Maven+Spring+SpringMVC+MyBatis框架搭建

  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：

91.    </build>

 二、第二点那必须是web.xml了：

24.        <filter-name>encodingFilter</filter-name>  
25.        <url-pattern>/*</url-pattern>  
26.    </filter-mapping>  
27.  
28.    <context-param>  
29.        <param-name>log4jConfigLocation</param-name>  
30.        <!-- <param-value>classpath*:config/log4j.properties</param-value> -->  
31.        <param-value>/WEB-INF/log4j.properties</param-value>  
32.    </context-param>  
33.    <listener>  
34.        <listener-class>  
35.            org.springframework.web.util.Log4jConfigListener  
36.        </listener-class>  
37.    </listener>  
38.      
39.    <!-- 加载所有的配置文件 -->  
40.    <context-param>  
41.        <param-name>contextConfigLocation</param-name>  
42.        <param-value>classpath*:config/applicationContext-*.xml</param-value>  
43.    </context-param>  
44.    <listener>  
45.        <listener-class>org.springframework.web.context.ContextLoaderListener  
46.        </listener-class>  
47.    </listener>  
48.  
49.    <!-- 配置springMVC -->  
50.    <servlet>  
51.        <servlet-name>springMVC</servlet-name>  
52.        <servlet-class>org.springframework.web.servlet.DispatcherServlet

54.        <init-param>  
55.            <param-name>contextConfigLocation</param-name>  
56.            <param-value>classpath*:config/spring_mvc.xml</param-value>

58.        <load-on-startup>1</load-on-startup>  
59.    </servlet>  
60.    <servlet-mapping>  
61.        <servlet-name>springMVC</servlet-name>  
62.        <url-pattern>/</url-pattern>  
63.    </servlet-mapping>  
64.  
65.</web-app>  


 三、springMVC配置文件：



Java代码 复制代码 收藏代码
1.<?xml version="1.0" encoding="UTF-8"?>  
2.<beans xmlns="http://www.springframework.org/schema/beans"  
3.    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"  
4.    xmlns:mvc="http://www.springframework.org/schema/mvc"  
5.    xsi:schemaLocation="http://www.springframework.org/schema/beans     
6.    http://www.springframework.org/schema/beans/spring-beans.xsd    
7.    http://www.springframework.org/schema/context    
8.    http://www.springframework.org/schema/context/spring-context-3.2.xsd    
9.    http://www.springframework.org/schema/mvc    
10.    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">  
11.  
12.    <!-- 注解扫描包 -->  
13.    <context:component-scan base-package="com.wang.cxf.test" />  
14.  
15.    <!-- 开启注解 -->  
16.    <mvc:annotation-driven />  
17.  
18.    <!-- 静态资源(js/image)的访问 -->  
19.    <mvc:resources location="/resource/" mapping="/resource/**" />  
20.  
21.    <!-- 定义视图解析器 -->  
22.    <bean id="viewResolver"  
23.        class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
24.        <property name="prefix" value="/view/"></property>  
25.        <property name="suffix" value=".jsp"></property>  
26.    </bean>  
27.  
28.</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，



Java代码 复制代码 收藏代码
1.<?xml version="1.0" encoding="UTF-8"?>  
2.<beans xmlns="http://www.springframework.org/schema/beans"  
3.    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   
4.    xmlns:jaxws="http://cxf.apache.org/jaxws"  
5.    xsi:schemaLocation="  
6.          http://www.springframework.org/schema/beans   
7.       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
8.       http://camel.apache.org/schema/spring   
9.       http://camel.apache.org/schema/spring/camel-spring.xsd  
10.       http://cxf.apache.org/jaxws   
11.       http://cxf.apache.org/schemas/jaxws.xsd">  
12.    <!-- 配置数据源 -->  
13.    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">  
14.        <property name="driverClass" value="com.mysql.jdbc.Driver" />  
15.        <property name="jdbcUrl" value="jdbc:mysql://localhost/mytest"></property>  
16.        <property name="user" value="root"></property>  
17.        <property name="password" value="123456"></property>  
18.    </bean>  
19.  
20.    <!-- mybatis 操作数据 -->  
21.    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">  
22.        <property name="configLocation" value="classpath:mybatis/mybatis-conf.xml"></property>  
23.        <property name="dataSource" ref="dataSource" />  
24.    </bean>  
25.  
26.    <bean class="org.mybatis.spring.SqlSessionTemplate">  
27.        <constructor-arg ref="sqlSessionFactory" />  
28.    </bean>  
29.  
30.    <!-- DAO接口所在包名，Spring会自动查找其下的类 -->  
31.    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">  
32.        <property name="basePackage" value="com.wang.cxf.test.dao" />  
33.        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>  
34.    </bean>  
35.  
36.</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。



Java代码 复制代码 收藏代码
1.<?xml version="1.0" encoding="UTF-8"?>  
2.<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">  
3.<mapper namespace="com.wang.cxf.test.dao.TestDao">  
4.  
5.    <select id="getAllTest" resultType="com.wang.cxf.test.model.Test">  
6.        select id, name from test  
7.    </select>  
8.  
9.</mapper>  


 之后，就能够想以前一样使用如下代码了：

1.@Autowired  
2.private TestDao testDao;  


 五、我的整个框架的结构：
