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

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">    <modelVersion>4.0.0</modelVersion>    <groupId>ssm</groupId>    <artifactId>com.cjq</artifactId>    <version>1.0-SNAPSHOT</version>    <dependencies>    <dependency>        <!--3.0的junit是使用编程的方式来进行测试，而junit4是使用注解的方式来运行junit-->        <groupId>junit</groupId>        <artifactId>junit</artifactId>        <version>4.11</version>        <scope>test</scope>    </dependency>    <!--补全项目依赖-->    <!--1.日志 java日志有:slf4j,log4j,logback,common-logging        slf4j:是规范/接口        日志实现:log4j,logback,common-logging        使用:slf4j+logback    -->    <dependency>        <groupId>org.slf4j</groupId>        <artifactId>slf4j-api</artifactId>        <version>1.7.12</version>    </dependency>    <dependency>        <groupId>ch.qos.logback</groupId>        <artifactId>logback-core</artifactId>        <version>1.1.1</version>    </dependency>    <!--实现slf4j接口并整合-->    <dependency>        <groupId>ch.qos.logback</groupId>        <artifactId>logback-classic</artifactId>        <version>1.1.1</version>    </dependency>    <!--1.数据库相关依赖-->    <dependency>        <groupId>mysql</groupId>        <artifactId>mysql-connector-java</artifactId>        <version>5.1.35</version>        <scope>runtime</scope>    </dependency>    <dependency>        <groupId>c3p0</groupId>        <artifactId>c3p0</artifactId>        <version>0.9.1.1</version>    </dependency>    <!--2.dao框架:MyBatis依赖-->    <dependency>        <groupId>org.mybatis</groupId>        <artifactId>mybatis</artifactId>        <version>3.3.0</version>    </dependency>    <!--mybatis自身实现的spring整合依赖-->    <dependency>        <groupId>org.mybatis</groupId>        <artifactId>mybatis-spring</artifactId>        <version>1.2.3</version>    </dependency>    <!--3.Servlet web相关依赖-->    <dependency>        <groupId>taglibs</groupId>        <artifactId>standard</artifactId>        <version>1.1.2</version>    </dependency>    <dependency>        <groupId>jstl</groupId>        <artifactId>jstl</artifactId>        <version>1.2</version>    </dependency>    <dependency>        <groupId>com.fasterxml.jackson.core</groupId>        <artifactId>jackson-databind</artifactId>        <version>2.5.4</version>    </dependency>    <dependency>        <groupId>javax.servlet</groupId>        <artifactId>javax.servlet-api</artifactId>        <version>3.1.0</version>    </dependency>    <!--4:spring依赖-->    <!--1)spring核心依赖-->    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-core</artifactId>        <version>4.1.7.RELEASE</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-beans</artifactId>        <version>4.1.7.RELEASE</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-context</artifactId>        <version>4.1.7.RELEASE</version>    </dependency>    <!--2)spring dao层依赖-->    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-jdbc</artifactId>        <version>4.1.7.RELEASE</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-tx</artifactId>        <version>4.1.7.RELEASE</version>    </dependency>    <!--3)springweb相关依赖-->    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-web</artifactId>        <version>4.1.7.RELEASE</version>    </dependency>    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-webmvc</artifactId>        <version>4.1.7.RELEASE</version>    </dependency>    <!--4)spring test相关依赖-->    <dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-test</artifactId>        <version>4.1.7.RELEASE</version>    </dependency>    </dependencies></project>

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"       xmlns:context="http://www.springframework.org/schema/context"       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">    <!--配置整合mybatis过程    1.配置数据库相关参数-->    <context:property-placeholder location="classpath:jdbc.properties"/>    <!--2.数据库连接池-->    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">        <!--配置连接池属性-->        <property name="driverClass" value="${driver}" />        <!-- 基本属性 url、user、password -->        <property name="jdbcUrl" value="${url}" />        <property name="user" value="${username}" />        <property name="password" value="${password}" />        <!--c3p0私有属性-->        <property name="maxPoolSize" value="30"/>        <property name="minPoolSize" value="10"/>        <!--关闭连接后不自动commit-->        <property name="autoCommitOnClose" value="false"/>        <!--获取连接超时时间-->        <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-->        <property name="configLocation" value="classpath:mybatis-config.xml"/>        <!--扫描entity包,使用别名,多个用;隔开-->        <property name="typeAliasesPackage" value="com.cjq.vo"/>        <!--扫描sql配置文件:mapper需要的xml文件-->        <property name="mapperLocations" value="classpath:mapper/*.xml"/>    </bean>    <!--４:配置扫描Dao接口包,动态实现DAO接口,注入到spring容器-->    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <!--注入SqlSessionFactory-->        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>        <!-- 给出需要扫描的Dao接口-->        <property name="basePackage" value="com.cjq.dao"/>    </bean></beans>

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. */@Transactionalpublic 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);    }}

web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4"         xmlns="http://java.sun.com/xml/ns/j2ee"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">  <!--用maven创建的web-app需要修改servlet的版本为3.1-->  <!--配置DispatcherServlet-->  <servlet>    <servlet-name>cjq-dispatcher</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <!--        配置SpringMVC 需要配置的文件        spring-dao.xml，spring-service.xml,spring-web.xml        Mybites -> spring -> springMvc    -->    <init-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:spring/spring-*.xml</param-value>    </init-param>  </servlet>  <servlet-mapping>    <servlet-name>cjq-dispatcher</servlet-name>    <!--默认匹配所有请求-->    <url-pattern>/</url-pattern>  </servlet-mapping>  <welcome-file-list>    <welcome-file>/login.jsp</welcome-file>  </welcome-file-list></web-app>
