Spring+SpringMVC+MyBatis+Maven框架整合

对于Spring、SpringMVC、MyBatis以及Maven有兴趣的同学，可以去查阅相关资料，这里不再赘述，本博文主要讲的是框架的整合。

1、创建Maven

• 在idea下兴建一个Maven项目，选择“Create from archetype‘,选择Maven app项目，点击下一步

• 填写相关配置

• maven配置选择默认（关于maven环境的配置，请查阅相关资料，这里不做赘述）

• 填写项目名，点击完成

2、配置pom.xml文件，引入需要的JAR包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          <password>tomcat</password>
        </configuration>
      </plugin>
    </plugins>

    <!--- 配置代码目录下的xml文件，没有此配置maven打好的war包会确实MyBatis对应的xml文件 -->
    <resources>
      <resource>
        <directory>src/main/java</directory>
        <includes>
          <include>**/*.properties</include>

        </includes>
        <filtering>false</filtering>
      </resource>
    </resources>
  </build>
</project>

3、新建配置jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf-8
jdbc.username=root
jdbc.password=

4、创建配置spring-mybatis.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:aop="http://www.springframework.org/schema/aop"
       xmlns:c="http://www.springframework.org/schema/c"
       xmlns:cache="http://www.springframework.org/schema/cache"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:jdbc="http://www.springframework.org/schema/jdbc"

       xmlns:oxm="http://www.springframework.org/schema/oxm"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:task="http://www.springframework.org/schema/task"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:util="http://www.springframework.org/schema/util"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.2.xsd
		http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd

		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">

    <!-- 开启spring注解配置 -->
    <context:annotation-config />

    <!-- 启用Spring Task @Scheduled 注解编程 -->
    <task:annotation-driven executor="executor" scheduler="scheduler" mode="proxy" />
    <task:scheduler id="scheduler" pool-size="10" />
    <task:executor id="executor" pool-size="5" />

    <!-- 扫描类包，将标注Spring注解的类自动转化Bean，同时完成Bean的注入 -->
    <context:component-scan base-package="com.loong.service" />
    <context:component-scan base-package="com.loong.mapper" />

    <!-- 1. 数据源 : DruidDataSource -->
    <!-- 加载配置文件 -->
    <context:property-placeholder location="classpath:jdbc.properties" />
    <!-- 数据库连接池 -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
          destroy-method="close">
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <property name="driverClassName" value="${jdbc.driver}" />
        <property name="maxActive" value="10" />
        <property name="minIdle" value="5" />
    </bean>

    <!--
        2. mybatis的SqlSession的工厂: SqlSessionFactoryBean dataSource:引用数据源

        MyBatis定义数据源,同意加载配置
    -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="configLocation" value="classpath:mybatis-config.xml" />
    </bean>

    <!--
        3. mybatis自动扫描加载Sql映射文件/接口 : MapperScannerConfigurer sqlSessionFactory

        basePackage:指定sql映射文件/接口所在的包（自动扫描）
    -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.loong.mapper"></property>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
    </bean>

    <!--
        4. 事务管理 : DataSourceTransactionManager dataSource:引用上面定义的数据源
    -->
    <bean id="txManager"
          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <!-- 5. 使用声明式事务
         transaction-manager：引用上面定义的事务管理器
     -->
    <tx:annotation-driven transaction-manager="txManager" />

</beans>

5、创建配置log4j.properties

#定义LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File=${catalina.home}/logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH:mm:ss}][%c]%m%n

6、创建配置mybatis-config.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>
    <plugins>
        <!-- com.github.pagehelper为PageHelper类所在包名 -->
        <plugin interceptor="com.github.pagehelper.PageHelper">
            <!-- 4.0.0以后版本可以不设置该参数 -->
            <property name="dialect" value="mysql"/>
        </plugin>
    </plugins>
</configuration>

7、创建测试表

/*
Navicat MySQL Data Transfer

Source Server         : test
Source Server Version : 50711
Source Host           : localhost:3306
Source Database       : ssm

Target Server Type    : MYSQL
Target Server Version : 50711
File Encoding         : 65001

Date: 2017-02-26 17:57:33
*/

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for `t_user`
-- ----------------------------
DROP TABLE IF EXISTS `t_user`;
CREATE TABLE `t_user` (
  `user_id` varchar(32) NOT NULL,
  `user_name` varchar(32) DEFAULT NULL,
  `user_password` varchar(32) DEFAULT NULL,
  `user_phone` varchar(32) DEFAULT NULL,
  `user_address` varchar(255) DEFAULT NULL,
  `user_email` varchar(32) DEFAULT NULL,
  PRIMARY KEY (`user_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

-- ----------------------------
-- Records of t_user
-- ----------------------------

8、利用MyBatis Generator自动创建代码，参考之前博文

9、UserService:

package com.loong.service;

import com.loong.pojo.User;

/**
 * Created by yvanme on 2017/2/26.
 */
public interface UserService {
    User info(String id)throws Exception;
}

10、UserServiceImpl:

package com.loong.service.impl;

import com.loong.mapper.UserMapper;
import com.loong.pojo.User;
import com.loong.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * Created by yvanme on 2017/2/26.
 */

@Service
public class UserServiceImpl implements UserService{
    @Autowired
    private UserMapper mapper;
    public User info(String id) throws Exception {
        return mapper.selectByPrimaryKey(id);
    }
}

11、测试Spiring+MyBatis

/**
 * Created by yvanme on 2017/2/26.
 */
import javax.annotation.Resource;

import com.loong.pojo.User;
import com.loong.service.UserService;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;


@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring-mybatis.xml"})

public class Test {
    @Resource
    private UserService userService;

    @org.junit.Test
    public void getUserInfo() throws Exception {
        User user = userService.info("1");
        System.out.println(user.getUserName());
    }
}

测试结果:

至此，Spiring+MyBatis整合成功

12、配置spring-mvc.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:p="http://www.springframework.org/schema/p"
       xmlns:util="http://www.springframework.org/schema/util"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
		http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">

    <!-- 启动扫描所有的controller -->
    <context:component-scan base-package="com.loong.controller"/>

    <mvc:annotation-driven />

    <!-- JSON转换器支持的类型列表 -->
    <util:list id="mediaTypes">
        <value>application/x-javascript;charset=UTF-8</value>
        <value>application/json;charset=UTF-8</value>
        <value>text/json;charset=UTF-8</value>
    </util:list>
</beans>

13、配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
         id="WebApp_ID" version="3.0">
  <display-name>ssm</display-name>

  <!-- The front controller of this Spring Web application, responsible for handling all application requests -->
  <servlet>

    <load-on-startup>1</load-on-startup>
  </servlet>
  <!-- Map all requests to the DispatcherServlet for handling -->
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!-- Spring character encording 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>
    <init-param>

      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!-- To initialize spring configuration files -->

  </context-param>

  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

14、测试，启动maven tomcat7插件

mvn tomcat7:run

测试结果：

至此，Spring+SpringMVC+MyBatis+Maven框架整合成功

15、源码下载
