1 spring 整合 spring mvc

啓動服務器時，加載 spring 配置文件

1.1 加載 spring 配置文件

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>

  <!--設置配置文件的路徑-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <!--解決中文亂碼-->
  <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>


  <!--配置 spring監聽器
    默認只加載 WEB-INF 目錄下的 apllicationContext.xml 配置文件-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>


  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!--加載 spring mvc 配置文件-->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <!--啓動服務器時就創建該 servlet-->
    <load-on-startup>1</load-on-startup>
  </servlet>
  
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>

1.2 Controller

package com.tzb.controller;

import com.tzb.service.IAccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

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

    @Autowired
    private IAccountService accountService;

    @RequestMapping("/findAll")
    public String findAll(){
        System.out.println("表現層：查詢所有的賬戶信息。。");

        accountService.findAll();
        return "list";
    }
}

2 搭建 mybatis

2.1 DAO

package com.tzb.dao;

import com.tzb.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;

import java.util.List;

public interface IAccountDao {

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

    @Insert("insert into account(name,money) values (#{name},#{money})")
    public void saveAccount(Account account);
}

2.2 mybatis 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>
    <!--配置環境-->
    <environments default="mysql">
        <environment id="mysql">
            <transactionManager type="JDBC"></transactionManager>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql:///ssm?useUnicode=true&amp;characterEncoding=utf-8"/>
                <property name="username" value="root"/>
                <property name="password" value="root"/>
            </dataSource>
        </environment>
    </environments>

    <!--引入映射文件-->
    <mappers>
      <!--  <mapper class="com.tzb.dao.IAccountDao"></mapper>-->
        <package name="com.tzb.dao"/>
    </mappers>
</configuration>

2.3 單元測試

package com.tzb.dao;

import com.tzb.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 IOException {
        // 加載 mybatis 配置文件
        InputStream in = Resources.getResourceAsStream("SqlMapConfig.xml");

        // 創建 SqlSessionFactory 對象
        SqlSessionFactory factory = new SqlSessionFactoryBuilder().build(in);

        SqlSession session = factory.openSession();

        //獲取代理對象
        IAccountDao accountDao = session.getMapper(IAccountDao.class);

        List<Account> accounts = accountDao.findAll();

        System.out.println(accounts);

        session.close();
        in.close();

    }
}

3 spring 整合 mybatis

3.1 spring 配置文件

spring 配置文件 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，只處理 service,dao-->
    <context:component-scan base-package="com.tzb">
        <!--配置哪些不掃描-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--spring 整合 mybatis-->
    <!--配置連接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql:///ssm?useUnicode=true&amp;characterEncoding=utf-8"/>
        <property name="user" value="root"/>
        <property name="password" value="root"/>
    </bean>

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

    <!--配置 IAccountDao 接口所在包-->
    <bean id="mapperScan" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.tzb.dao"></property>
    </bean>

</beans>

此時可以刪除 mybatis 配置文件 SqlMapConfig.xml

3.2 DAO添加註解

3.3 Service

package com.tzb.service.impl;

import com.tzb.dao.IAccountDao;
import com.tzb.domain.Account;
import com.tzb.service.IAccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service("accountService")
public class AccoutServiceImpl implements IAccountService {

    @Autowired
    private IAccountDao accountDao;

    @Override
    public List<Account> findAll() {
        System.out.println("業務層：查詢所有的賬戶信息");
        List<Account> accounts = accountDao.findAll();
        return accounts;
    }

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

3.4 Controller

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

    @Autowired
    private IAccountService accountService;

    @RequestMapping("/findAll")
    public String findAll(Model model){
        System.out.println("表現層：查詢所有的賬戶信息。。");
        List<Account> accounts= accountService.findAll();

        model.addAttribute("list",accounts);
        
        return "list";
    }
}

list.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
    <title>賬戶信息</title>
</head>
<body>
<h3>查詢所有的賬戶信息</h3>

<c:forEach items="${list}" var="account">
    ${account}
</c:forEach>

</body>
</html>

4.1 Controller


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

    @Autowired
    private IAccountService accountService;

    @RequestMapping("/findAll")
    public String findAll(Model model) {
        System.out.println("表現層：查詢所有的賬戶信息。。");
        List<Account> accounts = accountService.findAll();

        model.addAttribute("list", accounts);

        return "list";
    }

    @RequestMapping("/save")
    public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException {

        System.out.println("Controller:" + account);
        accountService.saveAccount(account);
        response.sendRedirect(request.getContextPath() + "/account/findAll");
    }
