springMVC + Spring + MyBatis 整合

整理下SSM（基于注解）的整合

1. web.xml 配置文件

4 : 接下来 是springmvc-servlet.xml 注意配置文件的存放位置

     <mvc:annotation-driven />
     <!-- 自动扫描Controller -->
     <context:component-scan base-package="com.pro.*" />
     <!-- 配置一个springmvc框架的视图解析器 -->

     <!--          一下暂时注释 ，这个主要是返回到 html 或JSP，ftl 等  如果采用这个 就想下一个配置的去掉就好 -->
   <!--
   <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

       <  property name="suffix" value=".jsp" />
     </bean>
     --> 

     <!--   配置这个主要是最近项目采用jQueryEasy 返回json数据 ，如果采用这个就讲上面的去掉就好    -->

     <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
         <property name="messageConverters">

5：sqlMapConfig.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>
     <!-- 定义别名 -->
     <typeAliases>
         <typeAlias alias="SysUser"  type="com.pro.system.entity.SysUser" />
     </typeAliases>
     <!-- 这里不需要再注册mybatis的SQL映射文件 ，因为在Spring的配置文件中配置sqlSessionFactory时注册了mapper的路径-->
 </configuration>     

6 ：jdbc.properties

 jdbc.driverClassName=oracle.jdbc.driver.OracleDriver
 jdbc.url=jdbc:oracle:thin:@localhost:1521:dbname
 jdbc.username=usename
 jdbc.password=password
 c3p0.pool.size.max=20
 c3p0.pool.size.min=5
 c3p0.pool.size.ini=3
 c3p0.pool.size.increment=2
