ssm框架搭建

结合前面文章，把spring ,springmvc,mybatis集成在一起。

新建maven项目ssm.

步骤：其中，先整合spring和mybatis,再整合springmvc

1,myecplise:new -web project,勾选 add maven support

2，pom.xml

3，加入以下类：

User：

package com.aluo.domain;

public class User {

    public User(int id, String phone, String password) {
        super();
        this.id = id;
        this.phone = phone;
        this.password = password;
    }

    private int id;
    private String phone;
    private String password;

    public int getId() {
        return id;
    }

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

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

}

接口UserMapper：

package com.aluo.mybatis;

import java.util.List;

import com.aluo.domain.User;

public interface UserMapper {
    User selectUser(int id);

    List<User> selectUserList();

    void insertUser(User user);

    void deleteUserById(int id);
}

UserMapper.xml：

<?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.aluo.mybatis.UserMapper">
    <select id="selectUser" resultType="com.aluo.domain.User">
        select * from user where id =
        #{id}
    </select>
    <select id="selectUserList" resultType="com.aluo.domain.User">
        select * from user
    </select>
    <insert id="insertUser">
        insert into user (phone,password)
        values
        (#{phone},#{password})
    </insert>
    <delete id="deleteUserById">
        delete from user where id = #{id}
    </delete>
</mapper>

接口UserDao：

package com.aluo.dao;

import java.util.List;

import com.aluo.domain.User;

public interface UserDao {
    User selectUser(int id);

    List<User> selectUserList();

    void inserttUser(User user);

    void deleteUserById(int id);
}

实现类UserDaoImpl：

package com.aluo.dao.Impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import com.aluo.dao.UserDao;
import com.aluo.domain.User;
import com.aluo.mybatis.UserMapper;

@Repository 
public class UserDaoImpl implements UserDao {
    @Autowired
    UserMapper userMapper;

    @Override
    public User selectUser(int id) {
        return userMapper.selectUser(id);
    }

    @Override
    public List<User> selectUserList() {
        return userMapper.selectUserList();
    }

    @Override
    public void inserttUser(User user) {
        userMapper.insertUser(user);
    }

    @Override
    public void deleteUserById(int id) {
        userMapper.deleteUserById(id);
    }

}

接口UserService：

package com.aluo.service;

import java.util.List;

import com.aluo.domain.User;

public interface UserService {
    User selectUser(int id);

    List<User> selectUserList();

    void insertUser(User user);

    void deleteUserById(int id);
}

实现类：UserServiceImpl：

package com.aluo.service.impl;

import java.util.List;

import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import com.aluo.dao.UserDao;
import com.aluo.domain.User;
import com.aluo.service.UserService;
import com.aluo.test.ssmTest;
@Service
//@Transactional (propagation = Propagation.REQUIRED, rollbackFor = Throwable.class)
public class UserServiceImpl implements UserService {
    @Autowired
    UserDao userDao;

    @Override
    public User selectUser(int id) {
        return userDao.selectUser(id);
    }

    @Override
    public List<User> selectUserList() {
        return userDao.selectUserList();
    }

    @Override
    public void insertUser(User user) {
        userDao.inserttUser(user);
       // int  a = 12/0;
    }

    @Override
    public void deleteUserById(int id) {
        userDao.deleteUserById(id);
    }

}

Controller类UserController：

package com.aluo.control;

import javax.annotation.Resource;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;

import com.aluo.domain.User;
import com.aluo.service.UserService;

@Controller
public class UserController {
    @Autowired
    UserService userService;

    @RequestMapping("/getUsser")
    public String getUser(ModelMap model) {
        model.addAttribute("user", userService.selectUser(3));
        return "user";
    }
    
    @RequestMapping("/selectUserList")
    public String selectUserList(ModelMap model) {
        model.addAttribute("userList", userService.selectUserList());
        return "userList";
    }
    
    @RequestMapping("/insertUser")
    public String insertUser(ModelMap model) {
        User user = new User(7, "7777", "777");
        userService.insertUser(user);
        model.addAttribute("message","insert success" );
        return "message";
    }
    
    @RequestMapping("/deleteUserById")
    public String deleteUserById(ModelMap model) {
        userService.deleteUserById(3);
        model.addAttribute("message", "delete success");
        return "message";
    }
}

4，新建测试类SsmTest：

package com.aluo.test;

import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.aluo.dao.UserDao;
import com.aluo.domain.User;
import com.aluo.mybatis.UserMapper;
import com.aluo.service.UserService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class SsmTest {
    private static Logger logger = Logger.getLogger(SsmTest.class);
    @Autowired
    private UserService userService;

    @Test
    public void test() {
        System.out.println("begin");
        System.out.println(userService.selectUser(3));
//        User user = new User(2, "999", "999");
//        userService.insertUser(user);
        // logger.info("value:" + userMapper.selectUser(3));
    }
}

output： com.aluo.domain.User@5aacc14

至此，spring和mybatis整合成功。接下来，再整合springmvc

5,web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
  <!-- 配置SpringMVC下的配置文件位置及名称 -->
   <display-name>Spring MVC Application</display-name>
   <!-- Spring和mybatis的配置文件 -->  
    <context-param>  
        <param-name>contextConfigLocation</param-name>  
        <param-value>classpath:applicationContext.xml</param-value>  
    </context-param>  
   
   <!-- Springmvc的配置文件 -->  
   <servlet>
      <servlet-name>ssm</servlet-name>
      <servlet-class>
         org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
      <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:ssm-servlet.xml</param-value>
    </init-param>
      <load-on-startup>1</load-on-startup>
   </servlet>
   <servlet-mapping>
      <servlet-name>ssm</servlet-name>
      <url-pattern>/</url-pattern>
   </servlet-mapping>
 <!-- Spring监听器 -->  
    <listener>  
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
    </listener>  
    <!-- 防止Spring内存溢出监听器 -->  
    <listener>
    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>  

</web-app>

6,web-inf下面新建文件夹jsp,再新建user.jsp,message.jsp,userList.jsp,贴出关键部分：

<body>
    This is my JSP page. <br>
    ${user }
  </body>

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<body>
    This is my JSP page.
    <br>
    <table align='center' border='1' cellspacing='0'>
        <tr>
            <td>id</td>
            <td>phone</td>
            <td>password</td>
        </tr>
        <c:forEach items="${userList}" var="c" varStatus="st">
            <tr>
                <td>${c.id}</td>
                <td>${c.phone}</td>
                <td>${c.password}</td>
            </tr>
        </c:forEach>
    </table>
</body>

 <body>
    This is my JSP page. <br>
    ${message }
  </body>

7，项目运行在tomcat7服务器。

访问http://localhost:8080/ssm/getUsser，如图：

访问：http://localhost:8080/ssm/selectUserList，如图：

访问：http://localhost:8080/ssm/insertUser，如图：

至此，基本搭建完成。

加上事务：

有两种，一种是注解，二是xml配置aop.

一，注解

1,applicationContext.xml加上以下代码

<tx:annotation-driven transaction-manager="transactionManager" />

2，类UserServiceImpl的方法insertUser加上出错代码

int a = 12/0;

3，UserServiceImpl加上

@Transactional (propagation = Propagation.REQUIRED, rollbackFor = Throwable.class)

如图；

4，再运行http://localhost:8080/ssm/insertUser，提示出错，事务回滚。

二，xml配置aop

1,,applicationContext.xml加上以下代码

<!-- 配置事务管理器 -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>
    <!-- 配置事务的增强 -->
    <tx:advice id="transactionAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="append*" propagation="REQUIRED" />
            <tx:method name="insert*" propagation="REQUIRED" />
            <tx:method name="save*" propagation="REQUIRED" />
            <tx:method name="update*" propagation="REQUIRED" />
            <tx:method name="modify*" propagation="REQUIRED" />
            <tx:method name="edit*" propagation="REQUIRED" />
            <tx:method name="delete*" propagation="REQUIRED" />
            <tx:method name="remove*" propagation="REQUIRED" />
            <tx:method name="repair" propagation="REQUIRED" />
            <tx:method name="delAndRepair" propagation="REQUIRED" />

            <tx:method name="get*" propagation="SUPPORTS" />
            <tx:method name="find*" propagation="SUPPORTS" />
            <tx:method name="load*" propagation="SUPPORTS" />
            <tx:method name="search*" propagation="SUPPORTS" />
            <tx:method name="datagrid*" propagation="SUPPORTS" />

            <tx:method name="*" propagation="SUPPORTS" />
        </tx:attributes>
    </tx:advice>
    <!-- 配置切面 -->
    <aop:config>
        <!-- 配置切点 -->
        <aop:pointcut expression="execution(* com.aluo.service.*.*(..))"
            id="pointcut1" />
        <!-- 配置切面 -->
        <aop:advisor advice-ref="transactionAdvice" pointcut-ref="pointcut1" />
    </aop:config>
    <!-- 开启注解事务 -->
    <tx:annotation-driven transaction-manager="transactionManager" />

2，类UserServiceImpl的方法insertUser加上出错代码

int a = 12/0;

3,再运行http://localhost:8080/ssm/insertUser，提示出错，事务回滚。
