Maven搭建SpringMVC+Mybatis项目详解
前言
最近比较闲,复习搭建一下项目,这次主要使用spring+SpringMVC+Mybatis。项目持久层使用Mybatis3,控制层使用SpringMVC4.1,使用Spring4.1管理控制器,数据库连接池使用druid数据源,该项数据库暂使用MySQL。(如果是Oracle需修改pom.xml)
<!-- oracle连接 -->
<dependency>
<groupId>com.hynnet</groupId>
<artifactId>oracle-driver-ojdbc6</artifactId>
<version>12.1.0.1</version>
</dependency>
1、 数据库表结构以及maven项目结构
数据表非常的简单(不是重点),如下:
创建Maven Project时,将Filter选择为org.apache.maven.archetypes。填写完相关项目坐标信息后项目结构如下:
注:若无src/main/Java,src/test/java,src/test/resources时,创建这个几个Source Folder。
2、修改pom.xml添加对应的包依赖
这儿将全部使用的Maven依赖贴出了,对应什么作用上面都有解释,如下:
pom.xml
- <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3、使用Generator自动生成Mybatis相关表信息
自动生成表的Model,Mapping,Dao文件,先关使用见文章http://blog.csdn.net/fengshizty/article/details/43086833
并将其导入到项目的src/main/java包中。
其中生成的Model中UserInfo如下:
UserInfo.java(其中List<CourseInfo> courseInfos手动添加的)
- package org.andy.shop.model;
- import java.util.List;
- public class UserInfo {
- private Integer id;
- private String uname;
- private Integer unumber;
- private List<CourseInfo> courseInfos;
- public Integer getId() {
- return id;
- }
- public void setId(Integer id) {
- this.id = id;
- }
- public String getUname() {
- return uname;
- }
- public void setUname(String uname) {
- this.uname = uname == null ? null : uname.trim();
- }
- public Integer getUnumber() {
- return unumber;
- }
- public void setUnumber(Integer unumber) {
- this.unumber = unumber;
- }
- public List<CourseInfo> getCourseInfos() {
- return courseInfos;
- }
- }
Dao包中的UserInfoMapper.java
- package org.andy.shop.dao;
- import java.util.List;
- import org.andy.shop.model.UserInfo;
- public interface UserInfoMapper {
- int deleteByPrimaryKey(Integer id);
- int insert(UserInfo record);
- int insertSelective(UserInfo record);
- UserInfo selectByPrimaryKey(Integer id);
- int updateByPrimaryKeySelective(UserInfo record);
- int updateByPrimaryKey(UserInfo record);
- List<UserInfo> selectAll();
- }
mapping 中的配置文件UserInfoMapper.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="org.andy.shop.dao.UserInfoMapper">
- <resultMap id="BaseResultMap" type="org.andy.shop.model.UserInfo">
- <id column="id" property="id" jdbcType="INTEGER" />
- <result column="uname" property="uname" jdbcType="VARCHAR" />
- <result column="unumber" property="unumber" jdbcType="INTEGER" />
- </resultMap>
- <sql id="Base_Column_List">
- id, uname, unumber
- </sql>
- <select id="selectByPrimaryKey" resultMap="BaseResultMap"
- parameterType="java.lang.Integer">
- select
- <include refid="Base_Column_List" />
- from user_info
- where id = #{id,jdbcType=INTEGER}
- </select>
- <delete id="deleteByPrimaryKey" parameterType="java.lang.Integer">

- </delete>
- <insert id="insert" parameterType="org.andy.shop.model.UserInfo">
- insert into user_info (id,

- )
- values (#{id,jdbcType=INTEGER},

- )
- </insert>
- <insert id="insertSelective" parameterType="org.andy.shop.model.UserInfo">
- insert into user_info
- <trim prefix="(" suffix=")" suffixOverrides=",">
- <if test="id != null">
- id,
- </if>
- <if test="uname != null">

- </trim>
- <trim prefix="values (" suffix=")" suffixOverrides=",">

- </trim>
- </insert>
- <update id="updateByPrimaryKeySelective" parameterType="org.andy.shop.model.UserInfo">
- update user_info
- <set>
- <if test="uname != null">
- uname = #{uname,jdbcType=VARCHAR},
- </if>
- <if test="unumber != null">
- unumber = #{unumber,jdbcType=INTEGER},
- </if>
- </set>
- where id = #{id,jdbcType=INTEGER}
- </update>
- <update id="updateByPrimaryKey" parameterType="org.andy.shop.model.UserInfo">
- update user_info
- set uname = #{uname,jdbcType=VARCHAR},
- unumber =
- #{unumber,jdbcType=INTEGER}
- where id = #{id,jdbcType=INTEGER}
- </update>
- <resultMap type="org.andy.shop.model.UserInfo" id="UserCourseMap"
- extends="BaseResultMap">
- <collection property="courseInfos" javaType="list"
- ofType="org.andy.shop.model.CourseInfo">
- <id property="id" column="course_id" jdbcType="INTEGER" />
- <result property="cname" column="cname" jdbcType="VARCHAR" />
- <result property="caddress" column="caddress" jdbcType="VARCHAR" />
- </collection>
- </resultMap>
- <select id="selectAll" resultMap="UserCourseMap">
- select u.id, u.uname,
- u.unumber, c.id course_id, c.cname, c.caddress from user_info u left
- join course_user_info cu on u.id = cu.uid
- left join course_info c on
- cu.cid = c.id
- </select>
- </mapper>
4、引入Spring并配置相关属性
在src/main/resources创建spring的配置文件,这里创建了spring.xml,信息如下:
- <?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-4.1.xsd
- http://www.springframework.org/schema/context
- http://www.springframework.org/schema/context/spring-context-4.1.xsd">
- <!--引入配置属性文件 -->
- <context:property-placeholder location="classpath:config.properties" />
- <!--自动扫描含有@Service将其注入为bean -->
- <context:component-scan base-package="org.andy.shop.service" />
- </beans>
5、引入Mybatis并配置数据连接池等信息
5.1、数据连接池druid配置信息
配置连接池配置信息在config.properties中,如下:
- #mysql version database druid setting
- validationQuery=SELECT 1
- jdbc.url=jdbc:mysql://localhost:3306/shop?useUnicode=true&characterEncoding=utf-8
- jdbc.username=root
- jdbc.password=12345
5.2、配置Mybatis相关信息
以下是mybatis的配置信息:spring-mybatis.xml(ps:名字可随便起)
- <?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:tx="http://www.springframework.org/schema/tx"
- xmlns:aop="http://www.springframework.org/schema/aop"
- xsi:schemaLocation="
- http://www.springframework.org/schema/beans
- http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
- http://www.springframework.org/schema/tx
- http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
- http://www.springframework.org/schema/aop
- http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
- ">
- <!-- 配置数据源 使用的是Druid数据源 -->
- <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
- init-method="init" destroy-method="close">
- <property name="url" value="${jdbc.url}" />
- <property name="username" value="${jdbc.username}" />
- <property name="password" value="${jdbc.password}" />
- <!-- 初始化连接大小 -->
- <property name="initialSize" value="0" />
- <!-- 连接池最大使用连接数量 -->
- <property name="maxActive" value="20" />
- <!-- 连接池最小空闲 -->
- <property name="minIdle" value="0" />
- <!-- 获取连接最大等待时间 -->
- <property name="maxWait" value="60000" />
- <property name="poolPreparedStatements" value="true" />
- <property name="maxPoolPreparedStatementPerConnectionSize"
- value="33" />
- <!-- 用来检测有效sql -->
- <property name="validationQuery" value="${validationQuery}" />
- <property name="testOnBorrow" value="false" />
- <property name="testOnReturn" value="false" />
- <property name="testWhileIdle" value="true" />
- <!-- 配置间隔多久才进行一次检测,检测需要关闭的空闲连接,单位是毫秒 -->
- <property name="timeBetweenEvictionRunsMillis" value="60000" />
- <!-- 配置一个连接在池中最小生存的时间,单位是毫秒 -->
- <property name="minEvictableIdleTimeMillis" value="25200000" />
- <!-- 打开removeAbandoned功能 -->
- <property name="removeAbandoned" value="true" />
- <!-- 1800秒,也就是30分钟 -->
- <property name="removeAbandonedTimeout" value="1800" />
- <!-- 关闭abanded连接时输出错误日志 -->
- <property name="logAbandoned" value="true" />
- <!-- 监控数据库 -->
- <property name="filters" value="mergeStat" />
- </bean>
- <!-- myBatis文件 -->
- <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
- <property name="dataSource" ref="dataSource" />
- <!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 -->
- <property name="mapperLocations" value="classpath:org/andy/shop/mapping/*.xml" />
- </bean>
- <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
- <property name="basePackage" value="org.andy.shop.dao" />
- <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
- </bean>
- <!-- 配置事务管理器 -->
- <bean id="transactionManager"
- class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
- <property name="dataSource" ref="dataSource" />
- </bean>
- <!-- 注解方式配置事物 -->
- <!-- <tx:annotation-driven transaction-manager="transactionManager" /> -->
- <!-- 拦截器方式配置事物 -->
- <tx:advice id="transactionAdvice" transaction-manager="transactionManager">
- <tx:attributes>
- <tx:method name="insert*" propagation="REQUIRED" />
- <tx:method name="update*" propagation="REQUIRED" />
- <tx:method name="delete*" propagation="REQUIRED" />
- <tx:method name="get*" propagation="SUPPORTS" read-only="true" />
- <tx:method name="find*" propagation="SUPPORTS" read-only="true" />
- <tx:method name="select*" propagation="SUPPORTS" read-only="true" />
- </tx:attributes>
- </tx:advice>
- <!-- Spring aop事务管理 -->
- <aop:config>
- <aop:pointcut id="transactionPointcut"
- expression="execution(* org.andy.shop.service..*Impl.*(..))" />
- <aop:advisor pointcut-ref="transactionPointcut"
- advice-ref="transactionAdvice" />
- </aop:config>
- </beans>
主要配置数据连接池,事务管理, mybatis关联映射等,事务采用aop的声明式事务。
6、引入日志
在src/main/resources中添加log4j日志配置信息:
log4j.properties
- ### set log levels ###
- log4j.rootLogger = INFO , C , D , E
- ### console ###
- log4j.appender.C = org.apache.log4j.ConsoleAppender
- log4j.appender.C.Target = System.out
- log4j.appender.C.layout = org.apache.log4j.PatternLayout
- log4j.appender.C.layout.ConversionPattern = [springmvc_mybatis_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n
- ### log file ###
- log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
- log4j.appender.D.File = ../logs/springmvc-mybatis-demo.log
- log4j.appender.D.Append = true
- log4j.appender.D.Threshold = INFO
- log4j.appender.D.layout = org.apache.log4j.PatternLayout
- log4j.appender.D.layout.ConversionPattern = [springmvc_mybatis_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n
- ### exception ###
- log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
- log4j.appender.E.File = ../logs/springmvc-mybatis-demo_error.log
- log4j.appender.E.Append = true
- log4j.appender.E.Threshold = ERROR
- log4j.appender.E.layout = org.apache.log4j.PatternLayout
- log4j.appender.E.layout.ConversionPattern = [sspringmvc_mybatis_demo][%p] [%-d{yyyy-MM-dd HH:mm:ss}] %C.%M(%L) | %m%n
7、创建Service
在src/main/java中创建相关的org.andy.shop.service包和org.andy.shop.service.Impl包。
UserService接口:
- package org.andy.shop.service;
- import java.util.List;
- import org.andy.shop.model.UserInfo;
- /**
- * 创建时间:2015-1-27 下午5:15:03
- * @author andy
- * @version 2.2
- */
- public interface UserService {
- UserInfo getUserById(int id);
- List<UserInfo> getUsers();
- int insert(UserInfo userInfo);
- }
UserServiceImpl实现Service:
- package org.andy.shop.service.impl;
- import java.util.List;
- import org.andy.shop.dao.UserInfoMapper;
- import org.andy.shop.model.UserInfo;
- import org.andy.shop.service.UserService;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.stereotype.Service;
- /**
- * 创建时间:2015-1-27 下午5:22:59
- *
- * @author andy
- * @version 2.2
- */
- @Service("userService")
- public class UserServiceImpl implements UserService {
- @Autowired
- private UserInfoMapper userInfoMapper;
- @Override
- public UserInfo getUserById(int id) {
- return userInfoMapper.selectByPrimaryKey(id);
- }
- @Override
- public List<UserInfo> getUsers() {
- return userInfoMapper.selectAll();
- }
- @Override
- public int insert(UserInfo userInfo) {
- int result = userInfoMapper.insert(userInfo);
- System.out.println(result);
- return result;
- }
- }
8、测试Spring和Mybatis配置
在src/test/java中写测试类,检测是否能够读出数据,若能读出则证明Spring+Mybatis整合成功。
TestUserService测试类:
- package org.andy.shop.service;
- import java.util.List;
- import org.andy.shop.model.UserInfo;
- 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.alibaba.fastjson.JSON;
- /**
- * 创建时间:2015-1-27 下午10:45:38
- *
- * @author andy
- * @version 2.2
- */
- @RunWith(SpringJUnit4ClassRunner.class)
- @ContextConfiguration(locations = { "classpath:spring.xml",
- "classpath:spring-mybatis.xml" })
- public class TestUserService {
- private static final Logger LOGGER = Logger
- .getLogger(TestUserService.class);
- @Autowired
- private UserService userService;
- @Test
- public void testQueryById1() {
- UserInfo userInfo = userService.getUserById(1);
- LOGGER.info(JSON.toJSON(userInfo));
- }
- @Test
- public void testQueryAll() {
- List<UserInfo> userInfos = userService.getUsers();
- LOGGER.info(JSON.toJSON(userInfos));
- }
- @Test
- public void testInsert() {
- UserInfo userInfo = new UserInfo();
- userInfo.setUname("xiaoming");
- userInfo.setUnumber(4);
- int result = userService.insert(userInfo);
- System.out.println(result);
- }
- }
若是测试成功,那证明已经成功了一半了。
9、引入SpringMVC
9.1 配置SpringMVC配置信息
SpringMVC的配置信息主要包括控制层Controller的bean管理,视图层和控制层配置等等,下面是spring-mvc.xml信息:
- <?xml version="1.0" encoding="UTF-8"?>
- <beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
- xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
- xsi:schemaLocation="http://www.springframework.org/schema/beans
- http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
- http://www.springframework.org/schema/context
- http://www.springframework.org/schema/context/spring-context-4.1.xsd
- http://www.springframework.org/schema/mvc
- http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd">
- <!-- 自动扫描controller包下的所有类,如果@Controller注入为bean -->
- <context:component-scan base-package="org.andy.shop.controller" />
- <!-- 避免IE执行AJAX时,返回JSON出现下载文件 -->
- <bean id="mappingJacksonHttpMessageConverter"
- class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
- <property name="supportedMediaTypes">
- <list>
- <value>text/html;charset=UTF-8</value>
- </list>
- </property>
- </bean>
- <!-- 启动Spring MVC的注解功能,完成请求和注解POJO的映射 -->
- <bean
- class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
- <property name="messageConverters">
- <list>
- <!-- json转换器 -->
- <ref bean="mappingJacksonHttpMessageConverter" />
- </list>
- </property>
- </bean>
- <!-- 对模型视图名称的解析,即在模型视图名称添加前后缀 -->
- <bean
- class="org.springframework.web.servlet.view.InternalResourceViewResolver">
- <property name="viewClass"
- value="org.springframework.web.servlet.view.JstlView" />
- <property name="prefix" value="/WEB-INF/views" />
- <property name="suffix" value=".jsp" />
- </bean>
- <!-- 配置多文件上传 -->
- <bean id="multipartResolver"
- class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
- <property name="defaultEncoding">
- <value>UTF-8</value>
- </property>
- <property name="maxUploadSize">
- <!-- 上传文件大小限制为31M,31*1024*1024 -->
- <value>32505856</value>
- </property>
- <property name="maxInMemorySize">
- <value>4096</value>
- </property>
- </bean>
- </beans>
自动扫描org.andy.shop.controller报下还有@Controller的控制层,注入为bean。
9.2、Web容器web.xml配置
web容器配置启动加载的配置文件,设置SpringMVC拦截的请求(此处拦截.htmls结尾的url请求)
- <?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
- xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
- id="WebApp_ID" version="2.5">

9.3、Controller控制层
在org.andy.shop.controller创建控制层,如UserController.java
- package org.andy.shop.controller;
- import java.util.List;
- import org.andy.shop.model.UserInfo;
- import org.andy.shop.service.UserService;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.stereotype.Controller;
- import org.springframework.ui.ModelMap;
- import org.springframework.web.bind.annotation.PathVariable;
- import org.springframework.web.bind.annotation.RequestMapping;
- import org.springframework.web.bind.annotation.ResponseBody;
- /**
- * 创建时间:2015-1-28 下午1:17:27
- * @author andy
- * @version 2.2
- */
- @Controller
- @RequestMapping("/user")
- public class UserController {
- @Autowired
- private UserService userService;
- @RequestMapping("/showInfo/{userId}")
- public String showUserInfo(ModelMap modelMap, @PathVariable int userId){
- UserInfo userInfo = userService.getUserById(userId);
- modelMap.addAttribute("userInfo", userInfo);
- return "/user/showInfo";
- }
- @RequestMapping("/showInfos")
- public @ResponseBody Object showUserInfos(){
- List<UserInfo> userInfos = userService.getUsers();
- return userInfos;
- }
- }
9.4、视图层
在WEB-INF创建视图总目录views(为了安全起见一般都在WEB-INF下创建),创建/user/showInfo.jsp视图文件。
- <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
- <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
- <html>
- <head>
- <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
- <title>userInfo</title>
- </head>
- <body>
- 姓名: ${userInfo.uname}
- </body>
- </html>
9.5、项目总目录结构
到此为demo以及基本创建完成总目录如下:
10、项目测试
将项目编译,Maven build...输入clean compile package,部署到Tomcat服务器,启动项目。
测试1:测试第一个url, http://localhost:8080/springmvc_mybatis_demo/user/showInfo/1.htmls
测试2:测试第二个json数据返回的url, http://localhost:8080/springmvc_mybatis_demo/user/showInfos.htmls
