@_@ 写在最前

之前分享过下面这几篇：

mybatis学习笔记（五） -- maven+spring+mybatis从零开始搭建整合详细过程（上）（附demo和搭建过程遇到的问题解决方法）

mybatis学习笔记（六） -- maven+spring+mybatis从零开始搭建整合详细过程（下）

springmvc学习笔记（一） -- 从零搭建，基础入门

这一篇，在这些练习的基础上，将它们整合在一起！

搭建步骤如下

一、新建maven项目，配置环境，测试是否配置成功

二、整合spring+mybatis，添加ApplicationContext.xml文件，修改pom.xml,，并连接mysql，测试是否搭建成功

（如果想了解单独的mybatis项目，可参考mybatis学习笔记(一）-- 简单入门（附测试Demo详细过程））

三、整合springmvc，添加springmvc-servlet.xml文件，修改调整，测试是否搭建成功

附：第一，二步详细操作步骤可参考

mybatis学习笔记（五） -- maven+spring+mybatis从零开始搭建整合详细过程（上）

mybatis学习笔记（六） -- maven+spring+mybatis从零开始搭建整合详细过程（下）

当然下面也会附上详细的搭建过程！

项目结构一览

现在开始体验！！!

一、新建maven项目

1、新建项目，然后修改几个配置，修改完如下：

2、添加Dynamic Web Module

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

Apply后，查看项目结构可以看到多了个WebContent

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

3、将WebContent下的两个文件复制到src/main/webapp下，然后将WebContent整个删掉

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

4、修改Deployment Assembly，只留下下面几个

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

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

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

5、测试，在src/main/webapp下，新建一个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>

运行tomcat，访问：http://localhost:8888/SSM01/，页面显示“hello”

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

到此，第一步骤完成！！！

二、整合Spring+MyBatis

1、修改pom.xml，加载项目需要的jar

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

        </dependency>

    </dependencies>

</project>

2、数据库准备

新建数据表tb_book，添加测试数据

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

3、新建包和类

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

（1）添加实体类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实现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，并注册映射

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

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属性文件 -->

    <context:property-placeholder location="classpath:db.properties" />

    <!--定义一个jdbc数据源，创建一个驱动管理数据源的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>

    <!--创建一个sql会话工厂bean，指定数据源 -->

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

        <!-- 指定数据源 -->

        <property name="dataSource" ref="jdbcDataSource" />

        <!--类型别名包，引入com.lmei.ssm.entity下的所有类 -->

        <property name="typeAliasesPackage" value="com.lmei.ssm.entity"></property>

        <!--指定sql映射xml文件的路径 -->

        <property name="mapperLocations"

            value="classpath:com/lmei/ssm/mapper/*Mapper.xml"></property>

    </bean>

    <!--自动扫描映射接口-->

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

        <!-- 指定sql会话工厂，在上面配置过的 -->

        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>

        <!-- 指定基础包，即自动扫描com.lmei.ssm.dao这个包下的所有接口类 -->

        <property name="basePackage" value="com.lmei.ssm.dao"></property>

    </bean>

      <!-- 创建一个sqlSession对象 -->

    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">

        <constructor-arg index="0" ref="sqlSessionFactory" />

    </bean>

    <!--自动扫描组件 -->

    <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、添加测试类

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

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");

        //获得bean

        BookDao bookDao = ctx.getBean(BookDao.class);

        //访问数据库

        List<Book> books = bookDao.getAllBook();

        for (Book book : books) {

            System.out.println(book.getBookName());

        }

        assertNotNull(books);

    }

}

Run As->JUnit Test

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

到此，第二步完成Spring+MyBatis+Mysql！！！

三、整合springmvc

1、修改实体类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下新建一个文件夹view，然后在里面新建hello.jsp文件，用来测试springmvc是否搭建成功

路径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、新建一个controller，HelloWorld.java

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

HelloWorld.java代码：

package com.lmei.ssm.controller;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.RequestMapping;

//@Controller是为了让Spring IOC容器初始化时自动扫描到；

//@RequestMapping是为了映射请求路径

@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")); //是否成功赋值

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">

    <!-- 自动扫描包，实现支持注解的IOC -->

    <context:component-scan base-package="com.lmei.ssm" />

    <!-- Spring MVC不处理静态资源 -->

    <mvc:default-servlet-handler />

    <!-- 支持mvc注解驱动 -->

    <mvc:annotation-driven />

    <!-- 视图解析器 -->

    <bean

        class="org.springframework.web.servlet.view.InternalResourceViewResolver"

        id="internalResourceViewResolver">

        <!-- 前缀 -->

        <property name="prefix" value="/WEB-INF/view/" />

        <!-- 后缀 -->

        <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容器启动监听器 -->

    <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配置文件路径 -->

            <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>

    <!--编码过滤器 -->

    <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>

之前在测试过程中，不小心把<url-pattern>/ 写错成 /*，导致springmvc把*.jsp,*.sql,*.txt都当做txt处理，访问页面时，直接在浏览器加载了jsp源码。

导致测试页面hello.jsp中的${message}一直取不到Controller传过来的值。

<servlet-mapping>

        <servlet-name>springmvc</servlet-name>

        <url-pattern>/</url-pattern>

</servlet-mapping>

6、测试，项目右键->Run As->Run On Server->Tomcat...

运行成功后，访问：http://localhost:8888/SSM01/Hello/SayHello

控制台输出：输出true，表示${message}赋值成功

到此，SpringMVC搭建成功！！！

继续整合！！！

7、在controller包下，新建一个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下新建一个文件夹Book，然后在文件夹内添加index.jsp

maven+springmvc+spring+mybatis+mysql详细搭建整合过程讲解

Book/index.jsp代码：

<%@ 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>图书管理</title>

</head>

<body>

    <div>

        <h3 class="title"><span>图书管理</span></h3>

        <table border="1" width="30%" class="tab">

            <tr>

                <th>编号</th>

                <th>书名</th>

            </tr>

            <c:forEach var="book" items="${books}">

                <tr>

                    <td>${book.id}</td>

                    <td>${book.bookName}</td>
