記錄心得-shiro框架demo示例

從懵懂到了解，再到熟悉，是一個進步的過程！

 

先擼代碼，跑起來看效果，再做詳細的介紹，開始干活！

1，先列出工程目錄結構，自己需要創建對應層級的程序和相關配置文件。

 

2，導入maven依賴的jar包。打開pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

3，配置web.xml文件。簡單的spring-mvc配置。

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         version="3.0">
  <display-name>Archetype Created Web Application</display-name>
  <!-- Spring和mybatis的配置文件 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring-mybatis.xml</param-value>
  </context-param>
  <!-- 編碼過濾器 -->
  <filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <async-supported>true</async-supported>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <!-- Spring監聽器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!-- 防止Spring內存溢出監聽器 -->
  <listener>
    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
  </listener>
  <!-- Spring MVC servlet -->
  <servlet>
    <servlet-name>SpringMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
    <async-supported>true</async-supported>
  </servlet>

  <!-- 配置由Spring提供的過濾器，用於整合shiro框架 -->
  <!-- 在項目啟動的過程中，當前過濾器會從Spring工廠中提取同名對象 -->
  <filter>
    <filter-name>shiroFilter</filter-name>
    <filter-class>
      org.springframework.web.filter.DelegatingFilterProxy
    </filter-class>
  </filter>
  <filter-mapping>
    <filter-name>shiroFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

　　　　　　　　　　　　
  <!-- Spring MVC 普通頁面攔截 -->
  <servlet-mapping>
    <servlet-name>SpringMVC</servlet-name>
    <!-- 此處可以可以配置成*.do，對應struts的后綴習慣 -->
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <welcome-file-list>
    <welcome-file>/index.jsp</welcome-file>
  </welcome-file-list>

</web-app>

 

4，配置數據庫配置文件jdbc.properties，需要配置自己的本地的數據庫信息。

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/自己的數據庫名稱
username=自己的數據庫登錄賬戶
password=自己的數據庫登錄密碼
#定義初始連接數
initialSize=0
#定義最大連接數
maxActive=20
#定義最大空閑
maxIdle=20
#定義最小空閑
minIdle=1
#定義最長等待時間
maxWait=60000

 

5，配置日志log4j.properties。注意 自己指定日志輸出的位置。

#定義LOG輸出級別
log4j.rootLogger=DEBUG,File  
#定義日志輸出目的地為控制台
#log4j.appender.Console=org.apache.log4j.ConsoleAppender
#log4j.appender.Console.Target=System.out
#可以靈活地指定日志輸出格式，下面一行是指定具體的格式
#log4j.appender.Console.layout = org.apache.log4j.PatternLayout
#log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

#文件大小到達指定尺寸的時候產生一個新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender  
#指定輸出目錄
log4j.appender.File.File = 需要自己配置輸出的日志位置及日志名稱。比如c:/desktop/shiro.log
#定義文件最大大小
log4j.appender.File.MaxFileSize = 10MB  
log4j.appender.File.Encoding = UTF-8
# 輸出所以日志，如果換成DEBUG表示輸出DEBUG以上級別日志
log4j.appender.File.Threshold = ALL  
log4j.appender.File.layout = org.apache.log4j.PatternLayout  
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n 

 

6，配置shiro-context.xml配置文件。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

                 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">

    <bean id="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
        <property name="securityManager" ref="securityManager" /> <!--加載管理器-->
        <property name="loginUrl" value="/user/login" />    <!--沒有登錄的時候，跳轉到這個頁面-->
        <property name="unauthorizedUrl" value="/user/nopermission" /> <!--當沒有權限的時候，跳轉到這個url-->
         
        <property name="filterChainDefinitions">
            <value>
                /user/login = anon <!--可以不需要登錄-->
                /user/readName = authc, perms[/readName]  <!-- perms 表示需要該權限才能訪問的頁面 -->
                /user/readData = authc, perms[/readData]
                /user/* = authc <!-- authc 表示需要認證才能訪問的頁面 -->
            </value>
        </property>
    </bean>

    <!-- 自定義Realm -->
    <bean id="myShiroRealm" class="com.Shiro.MyShiroReaml">
        <!-- businessManager 用來實現用戶名密碼的查詢 -->
        <property name="shiroService" ref="accountService" />
    </bean>

    <bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
        <!-- 注入realm -->
        <property name="realm" ref="myShiroRealm"/>
    </bean>

    <!--聲明一個Service 注入到自定義Realm-->
    <bean id="accountService" class="com.Service.Impl.ShiroServiceImpl"/>
    <!-- <bean id="shiroCacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager"> 
        <property name="cacheManager" ref="cacheManager" /> </bean> -->
</beans>

 

 

7，配置spring-mvc.xml文件。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

                        http://www.springframework.org/schema/context/spring-context-3.1.xsd
                        http://www.springframework.org/schema/mvc
                        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

    <import resource="shiro-context.xml"/>
    <!-- 自動掃描該包，使SpringMVC認為包下用了@controller注解的類是控制器 -->
    <context:component-scan base-package="com.*" />
    <!--避免IE執行AJAX時，返回JSON出現下載文件 -->
    <bean id="mappingJacksonHttpMessageConverter"
          class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
            </list>
        </property>
    </bean>

    <!-- 啟動SpringMVC的注解功能，完成請求和注解POJO的映射 -->
    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>
                <ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON轉換器 -->
            </list>
        </property>
    </bean>
    <!-- 定義跳轉的文件的前后綴 ，視圖模式配置-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 這里的配置我的理解是自動給后面action的方法return的字符串加上前綴和后綴，變成一個 可用的url地址 -->
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>

    <!-- 配置文件上傳，如果沒有使用文件上傳可以不用配置，當然如果不配，那么配置文件中也不必引入上傳組件包 -->
    <bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 默認編碼 -->

        <!-- 內存中的最大值 -->
        <property name="maxInMemorySize" value="40960" />
    </bean>

</beans>

 

 

 8，配置spring-mybatis.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

    <!-- 自動掃描 -->
    <context:component-scan base-package="com" />
    <import resource="shiro-context.xml"/>
    <!-- 引入配置文件 -->
    <bean id="propertyConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:jdbc.properties" />
    </bean>

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"

9，在本地數據庫維護初始化數據。

CREATE DATABASE `shirotest；USE `shirotest`;

/*Table structure for table `permission` */

DROP TABLE IF EXISTS `permission`;

CREATE TABLE `permission` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `url` varchar(30) NOT NULL,
  `roleid` int(11) DEFAULT NULL,
  `description` varchar(100) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

/*Data for the table `permission` */

insert  into `permission`(`id`,`url`,`roleid`,`description`) values (1,'/readName',1,'查看名單'),(2,'/readData',2,'查看數據');

/*Table structure for table `role` */

DROP TABLE IF EXISTS `role`;

CREATE TABLE `role` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `role` varchar(20) NOT NULL,
  `description` varchar(120) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

/*Data for the table `role` */

insert  into `role`(`id`,`role`,`description`) values (1,'管理員','管理員'),(2,'普通用戶','普通用戶');

/*Table structure for table `user` */

DROP TABLE IF EXISTS `user`;

CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `account` varchar(20) NOT NULL,
  `password` varchar(20) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

/*Data for the table `user` */

insert  into `user`(`id`,`account`,`password`) values (1,'123','123'),(2,'1234','1234');

/*Table structure for table `user_role` */

DROP TABLE IF EXISTS `user_role`;

CREATE TABLE `user_role` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `userid` int(11) NOT NULL,
  `roleid` int(11) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8 CHECKSUM=1 DELAY_KEY_WRITE=1 ROW_FORMAT=DYNAMIC;

/*Data for the table `user_role` */

insert  into `user_role`(`id`,`userid`,`roleid`) values (1,1,1),(2,2,2);

 

 

10，實現自己的reaml類。

package com.Shiro;

import com.Controller.loginController;
import com.Pojo.Permission;
import com.Pojo.User;
import com.Service.ShiroService;
import org.apache.log4j.Logger;
import org.apache.shiro.authc.*;

import org.apache.shiro.subject.PrincipalCollection;

import java.util.List;

public class MyShiroReaml extends AuthorizingRealm {
    private Logger logger = Logger.getLogger(MyShiroReaml.class);

0
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection pc) {
        logger.debug("doGetAuthorizationInfo----權限驗證");
        /**
         *
         * 流程
         * 1.根據用戶user->2.獲取角色id->3.根據角色id獲取權限permission
         */
        //方法一：獲得user對象
        User user=(User)pc.getPrimaryPrincipal();
        logger.debug("user========="+user);
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        //獲取permission
        if(user!=null) {
            List<Permission> permissionsByUser = shiroService.getPermissionsByUser(user);
            if (permissionsByUser.size()!=0) {

                    info.addStringPermission(p.getUrl());
                }
                return info;
            }

    private ShiroService shiroService;

    public ShiroService getShiroService() {
        return shiroService;
    }

    public void setShiroService(ShiroService shiroService) {
        this.shiroService = shiroService;
    }
}

 

11，完善pojo對象類。

Permission.java

package com.Pojo;

import org.springframework.stereotype.Component;

@Component
public class Permission {
    private int id;
    private String token;
    /**資源url**/
    private String url;
    /**權限說明**/
    private String description;
    /**所屬角色編號**/
    private int roleId;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getToken() {
        return token;
    }

    public void setToken(String token) {
        this.token = token;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public int getRoleId() {
        return roleId;
    }

    public void setRoleId(int roleId) {
        this.roleId = roleId;
    }

    @Override
    public String toString() {
        return "PermissionPojo{" +
                "id=" + id +
                ", token='" + token + '\'' +
                ", url='" + url + '\'' +
                ", description='" + description + '\'' +
                ", roleId=" + roleId +
                '}';
    }
}

 

Role.java

package com.Pojo;

public class Role {
    private int id;
    /**角色**/
    private String role;
    /**說明**/
    private String description;


    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getRole() {
        return role;
    }

    public void setRole(String role) {
        this.role = role;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    @Override
    public String toString() {
        return "Role{" +
                "id=" + id +
                ", role='" + role + '\'' +
                ", description='" + description + '\'' +
                '}';
    }
}

 

User.java

package com.Pojo;

import org.springframework.stereotype.Component;

@Component
public class User {
    private int id;
    private String account;
    private String password;

    public User(int id, String account, String password) {
        this.id = id;
        this.account = account;
        this.password = password;
    }

    public User() {
        super();
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getAccount() {
        return account;
    }

    public void setAccount(String account) {
        this.account = account;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    @Override
    public String toString() {
        return "UserPojo{" +
                "id=" + id +
                ", account='" + account + '\'' +
                ", password='" + password + '\'' +
                '}';
    }
}

 

12，開始寫驗證代碼，按照Controller-Service-Dao-Mapping

LoginController.java

package com.Controller;

import com.Pojo.User;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpSession;

@Controller
@RequestMapping("/user")
public class loginController {
    @Autowired
    private ShiroService shiroService;
    private Logger logger = Logger.getLogger(loginController.class);
    /**
     * 驗證登錄
     * @param username
     * @param password
     * @param session
     * @return url
     */
    @RequestMapping(value = "/login")
    public String Login(String username, String password, HttpSession session, Model model){
        if(username==null){
            model.addAttribute("message", "賬號不為空");
            return "login";
        }
        //主體,當前狀態為沒有認證的狀態“未認證”
        Subject subject = SecurityUtils.getSubject();
        // 登錄后存放進shiro token
        UsernamePasswordToken token=new UsernamePasswordToken(username,password);
        User user;
        //登錄方法（認證是否通過）
        //使用subject調用securityManager,安全管理器調用Realm
        try {
            //利用異常操作
            //需要開始調用到Realm中
            logger.debug("========================================");
            logger.debug("1、進入認證方法");
            subject.login(token);
            user = (User)subject.getPrincipal();
            session.setAttribute("user",subject);
            model.addAttribute("message", "登錄完成");
            logger.debug("登錄完成");
        } catch (UnknownAccountException e) {
            model.addAttribute("message", "賬號密碼不正確");
            return "index";
        }
        return "test";
    }

    @RequestMapping("/check")
    public String check(HttpSession session){
        Subject subject=(Subject)session.getAttribute("user");
        User user=(User)subject.getPrincipal();
        logger.debug(user.toString());
        return "permission";
    }

    @RequestMapping("/readName")
    public String readName(HttpSession session){

        return "name";
    }

    @RequestMapping("/readData")
    public String readData(){

        return "data";
    }


    @RequestMapping("/nopermission")
    public String noPermission(){
        return "error";
    }
}

 

ShiroService.java

package com.Service;

import com.Pojo.Permission;
import com.Pojo.User;

import java.util.List;
 
public interface ShiroService {

    /**
     * 根據賬號獲取賬號密碼

     */
     User getUserByUserName(String username);

    /**
     * 根據賬號獲取該賬號的權限
     *
     * @param user
     * @return List
     */
    List<Permission> getPermissionsByUser(User user);
}

 

ShiroServiceImpl.java

package com.Service.Impl;

import com.Dao.ShiroDao;

import com.Pojo.User;
import com.Service.ShiroService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.ArrayList;

    public User getUserByUserName(String username) {
        //根據賬號獲取賬號密碼
        User userByUserName = shiroDao.getUserByUserName(username);
        return userByUserName;
    }

    public List<Permission> getPermissionsByUser(User user) {
        //獲取到用戶角色userRole
        List<Integer> roleId = shiroDao.getUserRoleByUserId(user.getId());
        List<Permission> perArrary = new ArrayList<Permission>();

        if (roleId!=null&&roleId.size()!=0) {
            //根據roleid獲取peimission
            for (Integer i : roleId) {
                perArrary.addAll(shiroDao.getPermissionsByRoleId(i));
            }
        }

        System.out.println(perArrary);
        return perArrary;
    }
}

 

ShiroDao.java

package com.Dao;

import com.Pojo.Permission;
import com.Pojo.User;

    /**
     * 根據userId獲取角色id
     * @param id
     * @return LIST
     */
    List<Integer> getUserRoleByUserId(int id);
}

 

Shiro.xml

<?xml version="1.0" encoding="UTF-8" ?>

13，簡單的頁面jsp，可參考，也可自己擼前端的代碼，本文只起示例作用。

至此，框架搭建起了，測試代碼也擼好了。假設上面一切順利，沒有飄紅報錯，那么就可以用maven幫我們打個war包，直接扔tomcat上，跑起來玩了。如圖打包。瀏覽器訪問127.0.0.1:8080/mvc_shiro

 

實際操作中，可能不會很順利，有遇到一些問題，但是都解決了，現在沒法復現，所以暫不列出，如果有遇到問題的，歡迎留言討論。后續會把自己的一些理解添加到博文中，今天累了，先溜了。。
