框架搭建

spring SpringMVC mybatis maven 框架搭建

my git ： https://github.com/hejiawang

看了一段时间Android，学了学C++，搭个SSM的框架复习复习老本行。

原来的SSH——Struts，spring，hibernate，逐渐被现在的SSM取代，当然了，还有各有优缺点的。

搭的这个框架中的SpringMVC并不是返回页面，而是返回json数据，在前端的js中处理页面的展现，我是为了让Android客户端能够访问SpringMVC的controller，并给Android客户端返回json数据考虑的。

一、还是一样的，要先看maven中都引入什么包：

<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/maven-v4_0_0.xsd">

			</plugins>
		</pluginManagement>
	</build>
</project>

二、第二点那必须是web.xml了：

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

<web-app>

	<display-name>CXFTest</display-name>
<welcome-file-list>
		<welcome-file>view/test.jsp</welcome-file>
	</welcome-file-list>
	<!-- 配置字符集 -->
	<filter>
		<filter-name>encodingFilter</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-name>forceEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>encodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<context-param>
		<param-name>log4jConfigLocation</param-name>
		<!-- <param-value>classpath*:config/log4j.properties</param-value> -->
		<param-value>/WEB-INF/log4j.properties</param-value>
	</context-param>
	<listener>
		<listener-class>
			org.springframework.web.util.Log4jConfigListener
		</listener-class>
	</listener>
	
	<!-- 加载所有的配置文件 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath*:config/applicationContext-*.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>

	<!-- 配置springMVC -->
	<servlet>
		<servlet-name>springMVC</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet
		</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath*:config/spring_mvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>springMVC</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

</web-app>

三、springMVC配置文件：

<?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"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	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-3.2.xsd  
    http://www.springframework.org/schema/mvc  
    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

	<!-- 注解扫描包 -->
	<context:component-scan base-package="com.wang.cxf.test" />

	<!-- 开启注解 -->
	<mvc:annotation-driven />

	<!-- 静态资源(js/image)的访问 -->
	<mvc:resources location="/resource/" mapping="/resource/**" />

	<!-- 定义视图解析器 -->
	<bean id="viewResolver"
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/view/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>

</beans>

四、在搭建这步的时候有点费劲了。关键是spring和mybatis的整合，不太熟悉，不知道dao层怎么弄，

<?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:jaxws="http://cxf.apache.org/jaxws"
	xsi:schemaLocation="
          http://www.springframework.org/schema/beans 
       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
       http://camel.apache.org/schema/spring 
       http://camel.apache.org/schema/spring/camel-spring.xsd
       http://cxf.apache.org/jaxws 
       http://cxf.apache.org/schemas/jaxws.xsd">
	<!-- 配置数据源 -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="driverClass" value="com.mysql.jdbc.Driver" />
		<property name="jdbcUrl" value="jdbc:mysql://localhost/mytest"></property>
		<property name="user" value="root"></property>
		<property name="password" value="123456"></property>
	</bean>

	<!-- mybatis 操作数据 -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<property name="configLocation" value="classpath:mybatis/mybatis-conf.xml"></property>
		<property name="dataSource" ref="dataSource" />
	</bean>

	<bean class="org.mybatis.spring.SqlSessionTemplate">
		<constructor-arg ref="sqlSessionFactory" />
	</bean>

	<!-- DAO接口所在包名，Spring会自动查找其下的类 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.wang.cxf.test.dao" />
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
	</bean>

</beans>

spring和mybatis整合后，只需要写dao层的接口，不用写实现类，在mybatis的配置文件中就是dao层的实现类了。

<?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.wang.cxf.test.dao.TestDao">

	<select id="getAllTest" resultType="com.wang.cxf.test.model.Test">
		select id, name from test
	</select>

</mapper>

之后，就能够想以前一样使用如下代码了：
