20 SSM三大框架的整合

1.SSM整合的相关概念

(1)整合说明：SSM整合可以使用多种方式，优先使用XML + 注解的方式
(2)整合的思路
　　1.先搭建整合的环境
　　2.先把Spring的配置搭建完成
　　3.再使用Spring整合SpringMVC框架
　　4.最后使用Spring整合MyBatis框架

2.SSM环境搭建

(1)利用骨架创建一个webapp的maven项目

(2)修改pom文件，引入坐标依赖

    </dependency>

  </dependencies>

(3)完善项目目录结构，编写实体类

<1>domain包中编写Account.java

package lucky.domain;

import java.io.Serializable;

/**
 * 账户实体类
 */
public class Account implements Serializable {
    private Integer id;
    private String name;
    private Double money;

    public Integer getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Double getMoney() {
        return money;
    }

    public void setMoney(Double money) {
        this.money = money;
    }

    @Override
    public String toString() {
        return "Account{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", money=" + money +
                '}';
    }
}

<2>dao包下编写AccountDao接口

package lucky.dao;

import lucky.domain.Account;

import java.util.List;

/**
 * 账户dao接口
 * 注意：mybatis框架会帮我们生成代理对象，我们不必再编写其实现类
 */
public interface AccountDao {
    /**
     * 查询所有账户信息
     * @return
     */
    public List<Account> findAll();

    /**
     * 保存账户信息
     * @param account
     */
    public void saveAccount(Account account);
}

<3>service包下创建AccountService.java接口及其实现类AccountServiceImpl.java

AccountService.java接口

package lucky.service;

import lucky.domain.Account;

import java.util.List;

public interface AccountService {
    /**
     * 查询所有账户信息
     * @return
     */
    public List<Account> findAll();

    /**
     * 保存账户信息
     * @param account
     */
    public void saveAccount(Account account);
}

AccountServiceImpl.java

package lucky.service.impl;

import lucky.domain.Account;
import lucky.service.AccountService;

import java.util.List;

public class AccountServiceImpl implements AccountService {
    @Override
    public List<Account> findAll() {
        System.out.println("业务层查询所有账户");
        return null;
    }

    @Override
    public void saveAccount(Account account) {
        System.out.println("业务层：保存账户");
    }
}

(4)搭建和测试Spring的开发环境

<1>在ssm项目中的resources包下创建applicationContext.xml的配置文件，编写具体的配置信息。

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

    <!--开启注解扫描,希望处理service和dao,controller不需要Spring框架去处理-->
    <context:component-scan base-package="lucky">
        <!--配置哪些注解不扫描-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

</beans>

<2>对AccountServiceImpl.java文件添加spring注解

package lucky.service.impl;

import lucky.domain.Account;
import lucky.service.AccountService;
import org.springframework.stereotype.Service;

import java.util.List;

@Service("accountService")
public class AccountServiceImpl implements AccountService {
    @Override
    public List<Account> findAll() {
        System.out.println("业务层查询所有账户");
        return null;
    }

    @Override
    public void saveAccount(Account account) {
        System.out.println("业务层：保存账户");
    }
}

<3>在ssm_web项目中编写测试方法，进行测试

package lucky.test;

import lucky.service.AccountService;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class TestSpring {
    @Test
    public void testRun1(){
        //加载配置文件
        ApplicationContext ac=new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        //根据AccountServiceImpl注解配置的id(accountService),获取对象
        AccountService accountService = (AccountService) ac.getBean("accountService");
        //调用方法
        accountService.findAll();
    }
}

 (5)搭建和测试SpringMVC的开发环境

<1>在web.xml文件中配置前端控制器和解决中文乱码的过滤器

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>

  <!--配置前端控制器，让前端控制器去加载resources包下的springmvc.xml配置文件-->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!--全局的初始化参数-->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!--配置解决中文乱码的过滤器-->
  <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>
  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

</web-app>

<2>创建springmvc.xml的配置文件，编写配置文件

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

    <!-- 开启注解扫描,只扫描controller -->
    <context:component-scan base-package="lucky">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!-- 视图解析器对象 -->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!--配置控制器方法中return返回的字符串对应的同名文件所在目录-->
        <property name="prefix" value="/WEB-INF/pages/"/>
        <!--配置文件的后缀名-->
        <property name="suffix" value=".jsp"/>
    </bean>

    <!-- 设置静态资源不过滤 -->
    <mvc:resources location="/css/" mapping="/css/**" />
    <mvc:resources location="/images/" mapping="/images/**" />
    <mvc:resources location="/js/" mapping="/js/**" />

    <!-- 开启SpringMVC框架注解的支持 -->
    <mvc:annotation-driven/>


</beans>

<3>测试SpringMVC的框架搭建是否成功

index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <a href="/day20_ssm/account/findAll">测试</a>
</body>
</html>

AccountController.java控制器类

package lucky.controller;

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

/**
 *springmvc Controller控制器类
 */
@Controller
@RequestMapping(path = "/account")
public class AccountController {
    @RequestMapping(path = "/findAll")
    public String findAll(){
        System.out.println("表现层查询所有用户");
        return "success";
    }
}

(6)Spring整合SpringMVC的框架

<1>目的：在controller中能成功的调用service对象中的方法。
<2>在项目启动的时候，就去加载applicationContext.xml的配置文件，在web.xml中配置ContextLoaderListener监听器（该监听器只能加载WEB-INF目录下的applicationContext.xml的配置文件）。

<3>整合步骤

在web.xml文件中添加监听器：

<!-- 配置Spring的监听器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!-- 配置加载类路径的配置文件 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

在controller中注入service对象，调用service对象的方法进行测试

package lucky.controller;

import lucky.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 *springmvc Controller控制器类
 */
@Controller
@RequestMapping(path = "/account")
public class AccountController {
    @Autowired
    private AccountService accountService;

    @RequestMapping(path = "/findAll")
    public String findAll(){
        System.out.println("表现层查询所有用户");
        accountService.findAll();
        return "success";
    }
}

控制台输出：

(7)搭建和测试MyBatis的环境

<1>在resources包下编写SqlMapConfig.xml的配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <!--配置环境-->
    <environments default="mysql">
        <environment id="mysql">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql:///spring"/>
                <property name="username" value="root"/>
                <property name="password" value="plj824"/>
            </dataSource>
        </environment>
    </environments>

    <!-- 使用的是注解,引入映射配置文件 -->
    <mappers>
        <!-- 该包下所有的dao接口都可以使用 -->
        <package name="lucky.dao"/>
    </mappers>
</configuration>

<2>在AccountDao接口的方法上添加注解，编写SQL语句

package lucky.dao;

import lucky.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;

import java.util.List;

/**
 * 账户dao接口
 * 注意：mybatis框架会帮我们生成代理对象，我们不必再编写其实现类
 */
public interface AccountDao {
    /**
     * 查询所有账户信息
     * @return
     */
    @Select("select * from account")
    public List<Account> findAll();

    /**
     * 保存账户信息
     * @param account
     */
    @Insert("insert into account (name,money) values (#{name},#{money})")
    public void saveAccount(Account account);
}

<3>编写测试代码进行测试

package lucky.test;

import lucky.dao.AccountDao;
import lucky.domain.Account;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.Test;

import java.io.InputStream;
import java.util.List;

public class TestMybatis {
    @Test
    public void testRun1() throws Exception{
        // 加载配置文件
        InputStream inputStream = Resources.getResourceAsStream("SqlMapConfig.xml");
        // 创建工厂
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(inputStream);
        // 创建sqlSession对象
        SqlSession session = factory.openSession();
        // 获取代理对象
        AccountDao dao = session.getMapper(AccountDao.class);
        // 调用查询的方法
        List<Account> list = dao.findAll();
        for (Account account : list) {
            System.out.println(account);
        }
        // 释放资源
        session.close();
        inputStream.close();

    }

    @Test
    public void testRun2() throws Exception{
        Account account=new Account();
        account.setName("alice");
        account.setMoney(2300.0);
        // 加载配置文件
        InputStream inputStream = Resources.getResourceAsStream("SqlMapConfig.xml");
        // 创建工厂
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(inputStream);
        // 创建sqlSession对象
        SqlSession session = factory.openSession();
        // 获取代理对象
        AccountDao dao = session.getMapper(AccountDao.class);
        // 调用保存的方法
        dao.saveAccount(account);
        //提交事务
        session.commit();
        // 释放资源
        session.close();
        inputStream.close();

    }
}

(8)Spring整合MyBatis框架

<1>目的：把SqlMapConfig.xml配置文件中的内容配置到applicationContext.xml配置文件中,同时配置Spring的声明式事务管理

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

    <!--开启注解扫描,希望处理service和dao,controller不需要Spring框架去处理-->
    <context:component-scan base-package="lucky">
        <!--配置哪些注解不扫描-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--Spring整合Mybatis框架-->
    <!-- 配置C3P0的连接池对象 -->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql:///spring" />
        <property name="username" value="root" />
        <property name="password" value="plj824" />
    </bean>

    <!-- 配置SqlSession的工厂 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 配置扫描dao的包 -->
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="lucky.dao"/>
    </bean>

    <!--配置Spring框架声明式事务管理-->
    <!--配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!--配置事务通知-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="find*" read-only="true"/>
            <tx:method name="*" isolation="DEFAULT"/>
        </tx:attributes>
    </tx:advice>

    <!--配置AOP增强-->
    <aop:config>
        <aop:advisor advice-ref="txAdvice" pointcut="execution(* lucky.service.impl.*ServiceImpl.*(..))"/>
    </aop:config>

</beans>

注意：当applicationContext.xml配置的mybatis的相关内容后，SqlMapConfig.xml这个配置文件可以删除。

<2>在AccountDao接口中添加@Repository注解(目的：实现spring的IOC依赖注入)

package lucky.dao;

import lucky.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * 账户dao接口
 * 注意：mybatis框架会帮我们生成代理对象，我们不必再编写其实现类
 */
@Repository
public interface AccountDao {
    /**
     * 查询所有账户信息
     * @return
     */
    @Select("select * from account")
    public List<Account> findAll();

    /**
     * 保存账户信息
     * @param account
     */
    @Insert("insert into account (name,money) values (#{name},#{money})")
    public void saveAccount(Account account);
}

<3>在service中注入dao对象，进行测试

package lucky.service.impl;

import lucky.dao.AccountDao;
import lucky.domain.Account;
import lucky.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service("accountService")
public class AccountServiceImpl implements AccountService {
    @Autowired
    private AccountDao accountDao;

    @Override
    public List<Account> findAll() {
        System.out.println("业务层查询所有账户");
        return accountDao.findAll();
    }

    @Override
    public void saveAccount(Account account) {
        System.out.println("业务层：保存账户");
        accountDao.saveAccount(account);
    }
}

<4>AccountController.java

package lucky.controller;

import lucky.domain.Account;
import lucky.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
