SSM三大框架的整合

SSM三大框架的整合

搭建整合環境

1.整合說明：SSM整合有很多種方式，我們採用XML+註解的方式
2.整合思路：

先搭建整合的環境
先把Spring的配置搭建完成
使用Spring整合SpringMVC框架
使用Spring整合MyBatis框架

3.創建數據庫和表結構
DDL

4.創建maven工程（聚合和拆分）

創建ssm_parent父工程(打包方式選擇pom，必須)
創建ssm_web子模塊(打包方式是war包)
創建ssm_service子模塊(打包方式是jar包)
創建ssm_dao子模式(打包方式是jar包)
創建ssm_domain子模塊(打包方式是jar包)
web依賴於service,service依賴於dao,dao依賴於domain
再ssm_parent的pom.xml文件中引入座標依賴
pom.xml

再創建Account的三層結構

編寫Spring框架

1.配置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: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">
    
       <!-- 開啓註解掃描,要掃描的是service和dao層的註解，要忽略web(Controller)層註解，因爲web層讓SpringMVC框架去管理 -->
       <context:component-scan base-package="cn">
           <!-- 配置要忽略的註解 -->
           <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
       </context:component-scan>

</beans>

2.測試一下Spring是否配置成功
AccountServiceImpl.java

package cn.service.impl;

import cn.domain.Account;
import cn.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("業務層：查詢所有賬戶...");
        return null;
    }

    @Override
    public void saveAccount(Account account) {
        System.out.println("業務層：保存賬戶...");
    }
}

TestSpring.java

package cn.test;

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

public class TestSpring {

    @Test
    public void run1(){
        //加載配置文件
        ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        //獲取對象
        AccountService as = (AccountService) ac.getBean("accountService");
        //調用方法
        as.findAll();
    }
}

3.引入一個log4j.properties

# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE            debug   info   warn error fatal
log4j.rootCategory=debug, CONSOLE, LOGFILE

# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE

# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=d:\axis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

4.Spring配置成功控制檯輸出

編寫SpringMVC框架

1.配置web.xml

<!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 -->

      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <!-- 啓動服務器，創建servlet -->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!-- 解決中文亂碼過濾器 -->

  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

2,配置springmvc.xml

<?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"

       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">

       <!-- 開啓註解掃描，只掃描Controller註解 -->
       <context:component-scan base-package="cn">
           <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
       </context:component-scan>
       <!-- 配置視圖解析器對象 -->
       <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
           <property name="prefix" value="/WEB-INF/pages/"/>
           <property name="suffix" value=".jsp"/>
       </bean>
       <!-- 過濾靜態資源 -->
        <mvc:resources mapping="/css/**" location="/css/" />
        <mvc:resources mapping="/images/**" location="/images/" />
        <mvc:resources mapping="/js/**" location="/js/" />
       <!-- 開啓SpringMVC註解的支持 -->
        <mvc:annotation-driven/>
</beans>

3.測試一下SpringMVC是否配置成功
index.jsp

@Controller
@RequestMapping("/account")
public class AccountController {
    @RequestMapping("/findAll")
    public String findAll(){
        System.out.println("表現層：查詢所有賬戶信息...");
        return "list";
    }
}

4.成功頁面

Spring整合SpringMVC框架

1.分析

2.再次配置web.xml加監聽器
web.xml

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

  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
</web-app>

3.測試Spring和SpringMVC是否整合成功
AccountController.java

package cn.controller;

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

/**
 * 賬戶Web
 */
@Controller
@RequestMapping("/account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    @RequestMapping("/findAll")
    public String findAll(){
        System.out.println("表現層：查詢所有賬戶信息...");
        // 調用service的方法
        accountService.findAll();
        return "list";
    }
}

4.成功頁面

編寫Mybatis框架

1.配置SqlMapConfig.xml

<?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>
    <!-- 配置環境   -->
    <environments default="mysql">
        <!--  配置mysql環境 -->
        <environment id="mysql">
            <!-- 配置事務的類型 -->
            <transactionManager type="JDBC"/>
            <!-- 配置數據源(連接池) -->
            <dataSource type="POOLED">
                <!-- 配置連接數據庫的4個基本信息-->
                <property name="driver" value="com.mysql.cj.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://localhost:3306/ssm?userSSL=true&amp;useUnicode=true&amp;characterEncoding=UTF8&amp;serverTimezone=GMT"/>
                <property name="username" value="root"/>
                <property name="password" value="root"/>
            </dataSource>
        </environment>
    </environments>
    <!-- 引入映射配置文件 -->
    <mappers>
<!--        <mapper class="cn.dao.AccountDao"/>-->
        <package name="cn.dao"/>
    </mappers>
</configuration>

2.AccountDao.java

package cn.dao;

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

import java.util.List;

/**
 * 賬戶接口
 */
public interface AccountDao {

    //查詢所有賬戶信息
    @Select("select * from account")
    public List<Account> findAll();

    //保存賬戶信息
    @Insert("insert into account (name,money) values (#{name},#{money})")
    public void saveAccount(Account account);
}

3.測試Mybatis環境是否成功
TestMyBatis.java

package cn.test;

import cn.dao.AccountDao;
import cn.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.IOException;
import java.io.InputStream;
import java.util.List;

public class TestMyBatis {
    @Test
    public void run1() throws Exception {
        //加載配置文件
        InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
        //創建SqlSessionFactory對象
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
        //創建SqlSession對象
        SqlSession session = factory.openSession();
        //獲取到代理對象
        AccountDao dao = session.getMapper(AccountDao.class);
        //查詢所有賬戶信息
        List<Account> list = dao.findAll();
        for(Account account : list){
            System.out.println(account);
        }
        //釋放資源
        session.close();
        in.close();
    }
}

4.數據庫手動加一條記錄，看成功頁面

5.再測試一下保存方法
TestMyBatis.java

package cn.test;

import cn.dao.AccountDao;
import cn.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.IOException;
import java.io.InputStream;
import java.util.List;

public class TestMyBatis {
    /**
     * 測試查詢
     * @throws Exception
     */
    @Test
    public void run1() throws Exception {
        //加載配置文件
        InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
        //創建SqlSessionFactory對象
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
        //創建SqlSession對象
        SqlSession session = factory.openSession();
        //獲取到代理對象
        AccountDao dao = session.getMapper(AccountDao.class);
        //查詢所有賬戶信息
        List<Account> list = dao.findAll();
        for(Account account : list){
            System.out.println(account);
        }
        //釋放資源
        session.close();
        in.close();
    }

    /**
     * 測試保存
     * @throws Exception
     */
    @Test
    public void run2() throws Exception {
        Account account = new Account();
        account.setName("喬布斯");
        account.setMoney(400d);
        //加載配置文件
        InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");
        //創建SqlSessionFactory對象
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);
        //創建SqlSession對象
        SqlSession session = factory.openSession();
        //獲取到代理對象
        AccountDao dao = session.getMapper(AccountDao.class);
        //保存
        dao.saveAccount(account);
        //提交事務
        session.commit();
        //釋放資源
        session.close();
        in.close();
    }
}

6.數據庫插入成功頁面

Spring整合MyBatis框架

1.配置applicationContext.xml就是讓spring去配置連接池代替了mybatis中的SqlMapConfig.xml,就可以把SqlMapConfig.xml刪掉

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

       <!-- 開啓註解掃描,要掃描的是service和dao層的註解，要忽略web(Controller)層註解，因爲web層讓SpringMVC框架去管理 -->
       <context:component-scan base-package="cn">
           <!-- 配置要忽略的註解 -->
           <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
       </context:component-scan>

        <!-- Spring整合Mybatis框架 -->
        <!-- 配置連接池 -->

            <property name="basePackage" value="cn.dao"/>
        </bean>

</beans>

2.給AccountDao.java加註釋方法

package cn.dao;

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

import java.util.List;

/**
 * 賬戶接口
 */
@Repository
public interface AccountDao {

    //查詢所有賬戶信息
    @Select("select * from account")
    public List<Account> findAll();

    //保存賬戶信息
    @Insert("insert into account (name,money) values (#{name},#{money})")
    public void saveAccount(Account account);
}

3.修改AccountServiceImpl.java

package cn.service.impl;

import cn.dao.AccountDao;
import cn.domain.Account;
import cn.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("業務層：查詢所有賬戶...");
        return accountDao.findAll();
    }

    @Override
    public void saveAccount(Account account) {
        System.out.println("業務層：保存賬戶...");
        accountDao.saveAccount(account);
    }
}

4.修改AccountController.java

package cn.controller;

import cn.domain.Account;
import cn.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;

import java.util.List;

/**
 * 賬戶Web
 */
@Controller
@RequestMapping("/account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    @RequestMapping("/findAll")
    public String findAll(Model model){
        System.out.println("表現層：查詢所有賬戶信息...");
        // 調用service的方法
        List<Account> list = accountService.findAll();
        model.addAttribute("list",list);
        return "list";
    }
}

5.修改List.jsp

Spring整合MyBatis框架配置事務

1.在spring中的applicationContext.xml裏配置事務

           <!-- 配置要忽略的註解 -->
           <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
       </context:component-scan>

        <!-- Spring整合Mybatis框架 -->

</beans>

2.編寫index.jsp

<%--
  Created by IntelliJ IDEA.
  User: administrator
  Date: 2020/3/7
  Time: 23:46
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <a href="account/findAll">測試查詢</a>

    <h3>測試保存</h3>
    <form action="account/save" method="post">
        姓名：<input type="text" name="name"/><br/>
        金額：<input type="text" name="money"/><br/>
        <input type="submit" value="保存"/><br/>
    </form>
</body>
</html>

3.編寫AccountController.java，實現重定向保存數據後跳轉查看數據

package cn.controller;

import cn.domain.Account;
import cn.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;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;

/**
 * 賬戶Web
 */
@Controller
@RequestMapping("/account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    @RequestMapping("/findAll")
    public String findAll(Model model){
        System.out.println("表現層：查詢所有賬戶信息...");
        // 調用service的方法
        List<Account> list = accountService.findAll();
        model.addAttribute("list",list);
        return "list";
    }

    @RequestMapping("/save")
    public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException {
        accountService.saveAccount(account);
        //重定向
        response.sendRedirect(request.getContextPath()+"/account/findAll");
        return;
    }
}
