@_@ 寫在最前

之前分享過下面這幾篇：

mybatis學習筆記（五） -- maven+spring+mybatis從零開始搭建整合詳細過程（上）（附demo和搭建過程遇到的問題解決方法）

mybatis學習筆記（六） -- maven+spring+mybatis從零開始搭建整合詳細過程（下）

springmvc學習筆記（一） -- 從零搭建，基礎入門

這一篇，在這些練習的基礎上，將它們整合在一起！

 

搭建步驟如下

一、新建maven項目，配置環境，測試是否配置成功

二、整合spring+mybatis，添加ApplicationContext.xml文件，修改pom.xml,，並連接mysql，測試是否搭建成功

（如果想了解單獨的mybatis項目，可參考mybatis學習筆記(一）-- 簡單入門（附測試Demo詳細過程））

三、整合springmvc，添加springmvc-servlet.xml文件，修改調整，測試是否搭建成功

 

附：第一，二步詳細操作步驟可參考

mybatis學習筆記（五） -- maven+spring+mybatis從零開始搭建整合詳細過程（上）

mybatis學習筆記（六） -- maven+spring+mybatis從零開始搭建整合詳細過程（下）

 

當然下面也會附上詳細的搭建過程！ 

 

項目結構一覽

 

現在開始體驗！！!

一、新建maven項目

1、新建項目，然后修改幾個配置，修改完如下：

 

2、添加Dynamic Web Module

 

Apply后，查看項目結構可以看到多了個WebContent

 

3、將WebContent下的兩個文件復制到src/main/webapp下，然后將WebContent整個刪掉

 

4、修改Deployment Assembly，只留下下面幾個

新增/src/main/webapp，步驟Add->Floder->src->main->webapp->finish

 

5、測試，在src/main/webapp下，新建一個index.jsp文件

<%@ 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">
<title>Insert title here</title>
</head>
<body>hello
</body>
</html>

修改web.xml

<?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"
    id="WebApp_ID" version="3.0">
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

運行tomcat，訪問：http://localhost:8888/SSM01/，頁面顯示“hello”

到此，第一步驟完成！！！ 

 

二、整合Spring+MyBatis

1、修改pom.xml，加載項目需要的jar

<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/xsd/maven-4.0.0.xsd">

        </dependency>
    </dependencies>
</project>
pom.xml

 

2、數據庫准備

新建數據表tb_book，添加測試數據

 

3、新建包和類

 

（1）添加實體類Book

package com.lmei.ssm.entity;

public class Book {

    private int id;
    private String bookName;

    public int getId() {
        return id;
    }

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

    public String getBookName() {
        return bookName;
    }

    public void setBookName(String bookName) {
        this.bookName = bookName;
    }
    
    @Override
    public String toString() {
        return this.getId()+"\t"+this.getBookName();
    }
}

 

（2）添加Dao，BookDao

package com.lmei.ssm.dao;

import java.util.List;
import com.lmei.ssm.entity.Book;

public interface BookDao {

    public List<Book> getAllBook();
}

 

（3）添加service，BookService

package com.lmei.ssm.service;

import java.util.List;
import com.lmei.ssm.entity.Book;

public interface BookService {

    public List<Book> getAllBook();
}

 

（4）添加impl，BookServiceImpl實現BookService

package com.lmei.ssm.impl;

import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;

import com.lmei.ssm.dao.BookDao;
import com.lmei.ssm.entity.Book;
import com.lmei.ssm.service.BookService;

@Service public class BookServiceImpl implements BookService{
    @Resource
    BookDao bookDao;
    public List<Book> getAllBook() {    
        return bookDao.getAllBook();
    }
}

 

（5）添加BookMapper

<?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="com.lmei.ssm.dao.BookDao">
    <select id="getAllBook" parameterType="int" resultType="Book">
        select * from tb_book 
    </select>
</mapper>

 

4、添加ApplicationContext.xm和db.propertiesl文件，並注冊映射

ApplicationContext.xml

<?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"
    xmlns:aop="http://www.springframework.org/schema/aop" 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://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-4.3.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-4.3.xsd">

    <!-- 引入db.properties屬性文件 -->
    <context:property-placeholder location="classpath:db.properties" />

    <!--定義一個jdbc數據源，創建一個驅動管理數據源的bean -->
    <bean id="jdbcDataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="${jdbc.driver}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
    </bean>
    
    <!--創建一個sql會話工廠bean，指定數據源 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 指定數據源 -->
        <property name="dataSource" ref="jdbcDataSource" />
        <!--類型別名包，引入com.lmei.ssm.entity下的所有類 -->
        <property name="typeAliasesPackage" value="com.lmei.ssm.entity"></property>
        <!--指定sql映射xml文件的路徑 -->
        <property name="mapperLocations"
            value="classpath:com/lmei/ssm/mapper/*Mapper.xml"></property>
    </bean>
    
    <!--自動掃描映射接口-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!-- 指定sql會話工廠，在上面配置過的 -->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
        <!-- 指定基礎包，即自動掃描com.lmei.ssm.dao這個包下的所有接口類 -->
        <property name="basePackage" value="com.lmei.ssm.dao"></property>
    </bean>
  
      <!-- 創建一個sqlSession對象 -->
    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
        <constructor-arg index="0" ref="sqlSessionFactory" />
    </bean>
    
    
    <!--自動掃描組件 -->
    <context:component-scan base-package="com.lmei.ssm">
        <context:exclude-filter type="aspectj" expression="com.lmei.ssm.dao.*"/>
    </context:component-scan>
    <aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>
</beans>

db.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
jdbc.username=root
jdbc.password=123456

 

5、添加測試類

TestMyBatisSpring

package com.lmei.ssm.test;

import static org.junit.Assert.assertNotNull;
import java.util.List;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.lmei.ssm.dao.BookDao;
import com.lmei.ssm.entity.Book;

public class TestMyBatisSpring {
    @Test
    public void test() {
        //初始化容器
        ApplicationContext ctx=new ClassPathXmlApplicationContext("ApplicationContext.xml");
        //獲得bean     
        BookDao bookDao = ctx.getBean(BookDao.class);
        //訪問數據庫
        List<Book> books = bookDao.getAllBook();
        for (Book book : books) {
            System.out.println(book.getBookName());
        }
        assertNotNull(books);
    }
}

Run As->JUnit Test

到此，第二步完成Spring+MyBatis+Mysql！！！ 

 

三、整合springmvc

1、修改實體類Book

package com.lmei.ssm.entity;

import java.io.Serializable; public class Book implements Serializable {
    private static final long serialVersionUID = 1L; private int id;
    private String bookName;

    public int getId() {
        return id;
    }

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

    public String getBookName() {
        return bookName;
    }

    public void setBookName(String bookName) {
        this.bookName = bookName;
    }

    @Override
    public String toString() {
        return "id：" + getId() + "，bookName：" + getBookName() ;
    }

}

 

2、在WEB-INF下新建一個文件夾view，然后在里面新建hello.jsp文件，用來測試springmvc是否搭建成功

路徑webapp/WEB-INF/view/hello.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%-- <%@ page isELIgnored="false" %> --%>
<!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>
    <p>${message}</p>
</body>
</html>

 

3、新建一個controller，HelloWorld.java

HelloWorld.java代碼：

package com.lmei.ssm.controller;

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

//@Controller是為了讓Spring IOC容器初始化時自動掃描到；
//@RequestMapping是為了映射請求路徑
@Controller
@RequestMapping("/Hello")
public class HelloWorld {
    @RequestMapping("/SayHello")   
    public String SayHello(Model model) {        
        model.addAttribute("message", "Hello Spring MVC!");
        System.out.println(model.containsAttribute("message")); //是否成功賦值
return "hello";
    }   
}

 

 4、添加springmvc-servlet.xml

<?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-4.3.xsd
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">

    <!-- 自動掃描包，實現支持注解的IOC -->
    <context:component-scan base-package="com.lmei.ssm" />
    
    <!-- Spring MVC不處理靜態資源 -->
    <mvc:default-servlet-handler />

    <!-- 支持mvc注解驅動 -->
    <mvc:annotation-driven />
    
    <!-- 視圖解析器 -->
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver"
        id="internalResourceViewResolver">
        <!-- 前綴 -->
        <property name="prefix" value="/WEB-INF/view/" />
        <!-- 后綴 -->
        <property name="suffix" value=".jsp" />
    </bean>
    
</beans>

 

5、修改web.xml

<?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"
    id="WebApp_ID" version="3.0">

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

    <!-- Spring容器啟動監聽器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:ApplicationContext.xml</param-value>
    </context-param>

    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <!--Spring mvc配置文件路徑 -->
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:springmvc-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--編碼過濾器 -->
    <filter>
        <filter-name>characterEncodingFilter</filter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

之前在測試過程中，不小心把<url-pattern>/ 寫錯成 /*，導致springmvc把*.jsp,*.sql,*.txt都當做txt處理，訪問頁面時，直接在瀏覽器加載了jsp源碼。

導致測試頁面hello.jsp中的${message}一直取不到Controller傳過來的值。

<servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
</servlet-mapping>

 

6、測試，項目右鍵->Run As->Run On Server->Tomcat...

運行成功后，訪問：http://localhost:8888/SSM01/Hello/SayHello

控制台輸出：輸出true，表示${message}賦值成功

瀏覽器輸出：

到此，SpringMVC搭建成功 ！！！

 

繼續整合！！！

7、在controller包下，新建一個BookController

package com.lmei.ssm.controller;

import java.util.List;

import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.lmei.ssm.entity.Book;
import com.lmei.ssm.service.BookService;

@Controller @RequestMapping("/Book")
public class BookController {

    @Resource
    BookService bookService;

    @RequestMapping("/getAllBook")
    public String getAllBook(Model model) {
        List<Book> books = bookService.getAllBook();
        for (Book book : books) {
            System.out.println(book.getBookName());
        }
        
        model.addAttribute("books", books);
        return "Book/index";
    }
}

 

8、在WEB-INFO/view下新建一個文件夾Book，然后在文件夾內添加index.jsp

Book/index.jsp代碼：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>圖書管理</title>
</head>
<body>
    <div>
        <h3 class="title"><span>圖書管理</span></h3>       
        <table border="1" width="30%" class="tab">
            <tr>               
                <th>編號</th>
                <th>書名</th>                               
            </tr>
            <c:forEach var="book" items="${books}">
