使用intellij idea搭建spring-springmvc-mybatis整合框架环境

1.打开idea，创建maven项目，File-New-Project



2.选择Maven，勾选Create from archetype,选择org.apache.cocoon:cocoon-22-archetype-webapp,然后点击Next



3.填写Groupid和Artifactid点击Next



4.选择自己本地安装的maven



5.填写项目名创建项目完成



6.打开pom.xml加入坏境所需的依赖

7.添加Java目录















8.添加需要的包





9.建立资源文件



spring-dao.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"

1.配置数据库相关参数-->
<context:property-placeholder location="classpath:jdbc.properties"/>

<!--2.数据库连接池-->

<!--配置连接池属性-->
<property name="driverClass" value="${driver}" />

<!-- 基本属性 url、user、password -->

<property name="checkoutTimeout" value="10000"/>
<!--当获取连接失败重试次数-->
<property name="acquireRetryAttempts" value="2"/>
</bean>

<!--约定大于配置-->
<!--３.配置SqlSessionFactory对象-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!--往下才是mybatis和spring真正整合的配置-->
<!--注入数据库连接池-->
<property name="dataSource" ref="dataSource"/>
<!--配置mybatis全局配置文件:mybatis-config.xml-->

<!--配置spring mvc-->
<!--1,开启springmvc注解模式
a.自动注册DefaultAnnotationHandlerMapping,AnnotationMethodHandlerAdapter
b.默认提供一系列的功能:数据绑定，数字和日期的format@NumberFormat,@DateTimeFormat
c:xml,json的默认读写支持-->
<mvc:annotation-driven/>

<!--2.静态资源默认servlet配置-->
<!--
1).加入对静态资源处理：js,gif,png
2).允许使用 "/" 做整体映射
-->
<mvc:default-servlet-handler/>

<!--3：配置JSP 显示ViewResolver-->

<setting name="useColumnLabel" value="true"/>
<!--开启驼峰命名转换Table:create_time到 Entity(createTime)-->

</configuration>

9.增加必要主要类



UserMapper

package com.cjq.dao;

import com.cjq.model.User;

import java.util.List;

/**
* Created by struggle on 2017/7/26.
*/
public interface UserMapper {

List<User> getAll();

void save(User user);

void delete(int id);

void update(User user);

User getUserById(int id);

}

UserMapper.xml

<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.cjq.dao.UserMapper">
<!--目的:为dao接口方法提供sql语句配置
即针对dao接口中的方法编写我们的sql语句-->

<select id="getAll" resultType="com.cjq.model.User">
select * from user
</select>
<select id="getUserById" resultType="com.cjq.model.User" parameterType="int">
select * from user where id=#{id}
</select>
<insert id="save" parameterType="com.cjq.model.User">
insert into user(id,name,age,password) values(#{id},#{name},#{age},#{password})
</insert>
<delete id="delete" parameterType="int">
delete from user where id=#{id}
</delete>
<update id="update" parameterType="com.cjq.model.User">
update user set name=#{name},age=#{age},password=#{password} where id=#{id}
</update>
</mapper>

UserService

package com.cjq.service;

import com.cjq.model.User;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

/**
* Created by struggle on 2017/7/26.
*/
@Transactional
public interface UserService {

List<User> getAll();

void save(User user);

void delete(int id);

void update(User user);

User getUserById(int id);
}

UserServiceImpl

package com.cjq.service.impl;

import com.cjq.dao.UserMapper;
import com.cjq.model.User;
import com.cjq.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
* Created by struggle on 2017/7/26.
*/
@Service("userService")
public class UserServiceImpl implements UserService {

@Autowired
UserMapper userMapper;
public List<User> getAll() {
return userMapper.getAll();
}

public void save(User user) {
userMapper.save(user);
}

public void delete(int id) {
userMapper.delete(id);
}

public void update(User user) {
userMapper.update(user);
}

public User getUserById(int id) {
return userMapper.getUserById(id);
}
}

10.使用Spring-test 测试

UserServiceImplTest

package com.cjq.servoce.impl;

import com.cjq.model.User;
import com.cjq.service.UserService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import javax.annotation.Resource;
import java.util.Date;
import java.util.List;

/**
* Created by struggle on 2017/7/26.
*/

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:spring/spring-*.xml")
public class UserServiceImplTest {
@Resource
Date date;
@Resource
UserService userService;

@Test
public void testDate(){
System.out.println(date);
}
@Test
public void testGetAll(){
List<User> list=userService.getAll();
for(User user:list){
System.out.println(user.getName());
}
}
@Test
public void testGetUserById(){
System.out.println(userService.getUserById(1).getName());
}
@Test
public void testSave(){
User user=new User();
user.setName("test");
user.setAge(11);
user.setPassword("pass");
userService.save(user);
}
@Test
public void testDelete(){
userService.delete(1);
}
@Test
public void testUpdate(){
User user=userService.getUserById(2);
user.setName("hello");
userService.update(user);
}
}
