ssm框架整合

一、maven項目的搭建

1.首先建立一個maven項目，本次整合基於eclipse。

 

 

 

2.pom.xml的配置

<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.maven項目轉成web項目

新建的maven項目目錄結構和傳統的web項目目錄結構不一致，還需要做一些改動

（1）右鍵新建的項目，選擇properties選項

　　先把Dynamic Web Module選項去掉，點擊apply->OK。然后再重新進入此頁面，把Dynamic Web Module選上對應版本的話我選擇3.0，apply->OK。注意，此處Dynamic Web Module的版本對JDK版本是有要求的，具體要求的話，大家另行百度啦。

（2）如果建好的maven項目默認的JDK版本不是你本機裝的，那還需要修改maven的setting.xml配置文件，添加下面一段代碼，我本機安裝的JDK版本為1.8

 <profiles>
    <profile>

    <id>jdk-1.8</id>

    <activation>

        <activeByDefault>true</activeByDefault>

        <jdk>1.8</jdk>

    </activation>

    <properties>

        <maven.compiler.source>1.8</maven.compiler.source>

        <maven.compiler.target>1.8</maven.compiler.target>

        <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>

    </properties>

    </profile>

這時候，項目的目錄結構就多出了一個WebContent。將src目錄下的web.xml文件復制到WebContent->WEB-INF目錄下。此時的maven項目還需要在Navigator模式下，添加/src/main/java項目。

直接在main目錄下添加java文件夾

（3）選擇發布到tomcat的目錄

到這里為止，maven項目已經建完成，jar包也通過pom.xml文件關聯到項目了。下一步做springMvc + mybatis的整合

二、框架整合

1.新建一個spring-mvc.xml文件，用於配置spring注解和jsp頁面的映射

<?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:context="http://www.springframework.org/schema/context"  
       xmlns:mvc="http://www.springframework.org/schema/mvc"  
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd  
       http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> 
    <!-- 啟用SPRING MVC注解 -->
    <mvc:annotation-driven>
    </mvc:annotation-driven>
    
    <!-- 使用基於注解的方式注入java bean -->
    <context:component-scan base-package="com.xh.info.*"></context:component-scan>
    
    <!-- 配置jsp的訪問路徑 -->
    <bean id="Resolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/page/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>
       
</beans>

2.新建一個名為jdbc.properties的JDBC的配置文件，添加如下內容

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/db1
username=root
password=root
initialSize=0
maxActive=20
maxIdle=20
minIdle=1
maxWait=60000

3.新建一個名為spring-mybatis.xml文件，用於整合spring和mybatis，添加如下內容

<?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:mybatis="http://mybatis.org/schema/mybatis-spring"  
       xmlns:context="http://www.springframework.org/schema/context"  
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  
       http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring.xsd  
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

    <!-- 關聯JDBC文件 -->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    
    <!-- 數據庫源配置 -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
        destroy-method="close">
        <property name="driverClassName" value="${driver}"></property>
        <property name="url" value="${url}" />
        <property name="username" value="${username}" />
        <property name="password" value="${password}" />
        <!-- 初始化連接大小 -->
        <property name="initialSize" value="${initialSize}"/>
        <!-- 連接池最大數量 -->
        <property name="maxActive" value="${maxActive}"/>
        <!-- 連接池最大空閑 -->
        <property name="maxIdle" value="${maxIdle}"/>
        <!-- 連接池最小空閑 -->
        <property name="minIdle" value="${minIdle}"/>
        <!-- 獲取連接最大等待時間 -->
        <property name="maxWait" value="${maxWait}"/>
    </bean>
       
     <!-- spring和mybatis整合 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="mapperLocations" value="classpath:com/xh/mappers/*.xml"></property>
    </bean>
    
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
</beans>

4.新建lo4f.properties文件，用於配置日志信息。

log4j.rootLogger=INFO,Console,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 = logs/ssm.log
#定義文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 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]

上面四個文件完成了springMvc的配置，spring和mybatis的整合配置，日志信息的配置。最后還需要在web.xml文件將配置 文件和項目關聯起來，附上web.xml的代碼

<?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>ssmDemo</display-name>    
    
    <!-- spring和mybatis整合的文件 -->
    <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>
    
    <!-- spring 內存溢出監聽器 -->
    <listener>
        <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
    </listener>
    
    <!-- springMvc servlet配置 -->
    <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>
    <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>

三、demo測試，搭建好的框架是否可用

1.建立controller類，測試springMvc的功能是否搭建成功

DemoController.java文件的內容如下

package com.demo.controller;


import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
@RequestMapping("/demo")
public class DemoController {
    
    /**
     * 定義一個跳轉到WEB-INF/page目錄下，名為resultPage.jsp的頁面
     * @param request
     * @return
     */
    @RequestMapping("test")
    public ModelAndView resultPage(HttpServletRequest request){
        ModelAndView mav  = new ModelAndView();
        mav.addObject("info", "此信息來自DemoController 的 test方法");
        mav.setViewName("resultPage");
        return mav;
    }
    
}    

 

在WEB-INF目錄下建一個叫page的文件夾，新建一個名為resultPage的jsp文件，此處新建的名字和方法中setViewName里的要一致。貼上resultPage.jsp文件

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
    <div> ${info}  </div>
</body>
</html>

測試結果：

下一步測試往數據庫里插入記錄

（1）新建一個t_product的表，附上表結構

 （2）建立實體類

package com.demo.model;

import java.io.Serializable;
import java.util.Date;

/**
 * 實體屬性和表屬性名一致，可以省去在配置文件映射的步驟
 * @author Administrator
 *
 */
public class Product implements Serializable{

    private static final long serialVersionUID = -3560655699428032777L;
    
    private Integer id;
    
    private String pname;
    
    private String pnumber;
    
    private String ptype;
    
    private Date pdate;
    
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getPname() {
        return pname;
    }
    public void setPname(String pname) {
        this.pname = pname;
    }
    public String getPnumber() {
        return pnumber;
    }
    public void setPnumber(String pnumber) {
        this.pnumber = pnumber;
    }
    public String getPtype() {
        return ptype;
    }
    public void setPtype(String ptype) {
        this.ptype = ptype;
    }
    public Date getPdate() {
        return pdate;
    }
    public void setPdate(Date pdate) {
        this.pdate = pdate;
    }
    
}

（3）新建名為ProductMapper.xml的映射文件，用於操作表t_product，配置：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
 "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="ProductMapper">
    <parameterMap type="com.demo.model.Product" id="ProductMap"></parameterMap>
    <resultMap type="com.demo.model.Product" id="Product"></resultMap>
    <sql id="feild">(pname,pnumber,ptype,pdate)</sql>
    
    <insert id="insertProductSql" parameterMap="ProductMap">
        insert into t_product <include refid="feild"/> values
        (#{pname},#{pnumber},#{ptype},#{pdate})
    </insert>
</mapper>

（4）在controller中寫一個新方法，用來接收頁面的傳參。

@RequestMapping("product")
    public ModelAndView dbPage(HttpServletRequest request){
        ModelAndView mav  = new ModelAndView();
        
        String name = request.getParameter("name");
        String number = request.getParameter("number");
        String type = request.getParameter("type");
        
        Product p = new Product();
        p.setPname(name);
        p.setPnumber(number);
        p.setPtype(type);
        p.setPdate(new Date());
        
        productService.saveObj(p);
        mav.addObject("success", "保存成功");
        mav.setViewName("success");
        return mav;
    }

 

（5）開始用於測試的resultPage.jsp頁面，修改一下，用來添加記錄

<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<script type="text/javascript">
    function product(){
        var pro = document.getElementById("productForm");
        pro.submit();
    }
</script>
<title>Insert title here</title>
</head>
<body>
    <form action="/ssmDemo/demo/product" id="productForm" method="post">
        <label>商品名稱：</label><input type="text" name="name"><br />
        <label>商品編號：</label><input type="text" name="number"><br />
        <label>商品類型：</label><input type="text" name="type"><br />
        <input type="button" value="添加" onclick="product()">
    </form>
</body>
</html>

（6）構建service和對應的實現類，ProductService和ProductServiceImpl代碼

package com.demo.service;

import com.demo.model.Product;

public interface ProductService {
    void saveObj(Product p);
}

package com.demo.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.demo.base.BaseDao;
import com.demo.model.Product;
import com.demo.service.ProductService;

@Service("productService")
public class ProductServiceImpl implements ProductService{

    @Resource(name="baseDao")
    private BaseDao baseDao;
    
    @Override
    public void saveObj(Product p) {
        if(p != null){
            baseDao.saveObject("ProductMapper.insertProductSql", p);
        }
    }

}

（7）構建Dao層的代碼，附上BaseDao和BaseDaoImpl代碼

package com.demo.base;

public interface BaseDao {
    
    /**
     * 數據保存
     * @param sql    保存sql
     * @param obj    保存對象
     */
    void saveObject(String sql,Object obj);
    
}

package com.demo.base.impl;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.support.SqlSessionDaoSupport;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import com.demo.base.BaseDao;

@Repository("baseDao")
public class BaseDaoImpl extends SqlSessionDaoSupport implements BaseDao{

    /**
     * 注入sessionFactory
     */
    @Autowired
    public void setSqlSessionFactory(SqlSessionFactory sqlSessionFactory) {

        super.setSqlSessionFactory(sqlSessionFactory);
    }

    @Override
    public void saveObject(String sql, Object obj) {
        getSqlSession().insert(sql, obj);
    }
    
    
}

最后通過瀏覽器測試

數據庫記錄

 

 THE END！
