Springmvc+spring+maven+Mybatis整合

随着springmvc及maven越来越受到众多开发者的青睐，笔者主要结合springmvc+maven+spring+Mybatis，搭建一套用于开发和学习的框架。本文将一步步展示整个框架的搭建过程，方便交流和学习。

一、开发环境：

windows 8.1

eclipse Luna Service Release 1 (4.4.1)

mysql-5.6.19-winx64

maven-3.2.3

jdk 1.7

apache-tomcat-7.0.57

二、主要技术：

springmvc + spring + Mybatis

三、项目整体结构：

四、创建maven项目

maven主要是一个jar包管理，构建的工具。大家都知道java开发的第三方的框架和工具纷繁众多，maven就可以把开发者从这样一个jar管理的工作中解脱出来。更好的去关注代码的开发和业务。

a.配置maven插件

eclipse 和maven的集成需要一个插件，

插件地址：http://download.jboss.org/jbosstools/updates/stable/luna/

eclipse 配置maven的步骤：

Eclipse-Help — Install New Software—work with:

输入地址 http://download.jboss.org/jbosstools/updates/stable/luna/

b.创建maven项目

Select All(全选)，然后一直下一步，安装完成会提示重启Eclipse即可。

第一步：创建maven project



第二步：配置maven项目坐标等信息



如图：需要配置groupid，artifactid，packaging（这里时web项目，配置为war）

parentproject更多会用在存在众多的颗粒的系统中，这里不做配置。

关于详细的配置信息：推荐《maven实战》这本书，可以在网上搜到。

c.配置pom.xml

<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>

四、整合spring和Mybatis

a.配置spring-mybatis文件

<?xml version="1.0" encoding="UTF-8"?>

</property>
</bean>
<aop:config>
<aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" />

</beans>

b.配置spring-mvc文件

<?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-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
">

<!-- 引入属性文件 -->
<context:property-placeholder location="classpath:config.properties" />

<!-- 自动描述（自动注入） -->
<context:component-scan base-package="com.ict.base.service" />
</beans>

c.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.ict.base.dao.UserMapper" >
<resultMap id="BaseResultMap" type="com.ict.base.model.User" >
<result column="name" property="name" jdbcType="VARCHAR" />
<result column="id" property="id" jdbcType="INTEGER" />
<result column="age" property="age" jdbcType="VARCHAR" />
</resultMap>
<insert id="insert" parameterType="com.ict.base.model.User" >
insert into user (name, id, age
)
values (#{name,jdbcType=VARCHAR}, #{id,jdbcType=INTEGER}, #{age,jdbcType=VARCHAR}
)
</insert>
<insert id="insertSelective" parameterType="com.ict.base.model.User" >
insert into user
<trim prefix="(" suffix=")" suffixOverrides="," >
<if test="name != null" >
name,
</if>
<if test="id != null" >
id,
</if>
<if test="age != null" >
age,
</if>
</trim>
<trim prefix="values (" suffix=")" suffixOverrides="," >
<if test="name != null" >
#{name,jdbcType=VARCHAR},
</if>
<if test="id != null" >
#{id,jdbcType=INTEGER},
</if>
<if test="age != null" >
#{age,jdbcType=VARCHAR},
</if>
</trim>
</insert>
<select id="selectByPrimaryKey" resultMap="BaseResultMap">
select *
from user
where id = #{id}
</select>
</mapper>

d.测试spring和Mybatis整合

@Test
public void test1(){
ApplicationContext ac =new ClassPathXmlApplicationContext(new
String[] {"spring.xml","spring-mybatis.xml"});
UserServiceI userService=(UserServiceI) ac.getBean("userService");
System.out.println(userService);
User user=userService.getUserById(1);
System.out.println(user.getName().toString());
}

五、整合springmvc和spring

a.配置spring-mvc文件

<?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-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd"> 
<!-- 自动扫描controller包下的所有类，使其认为spring mvc的控制器 -->

<context:component-scan base-package="com.ict.base.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.MappingJacksonHttpMessageConverter">
<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>
<ref bean="mappingJacksonHttpMessageConverter" /><!-- json转换器 -->
</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" p:prefix="/" p:suffix=".jsp" />

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding">
<value>UTF-8</value>
</property>
<property name="maxUploadSize">
<value>32505856</value><!-- 上传文件大小限制为31M，31*1024*1024 -->
</property>
<property name="maxInMemorySize">
<value>4096</value>
</property>
</bean>

</beans>

b.测试spring-mvc和spring

<%@ page language="java" pageEncoding="UTF-8"%>
<!DOCTYPE HTML>
<html>
<body>
<h2>Hello World!</h2>
用户名：${user.name}
</body>
</html>

访问地址：最后使用的是restful的方式来访问的

http://localhost:8080/baseInter/userController/showUserName/2.do
