springMVC总结
最近想了解下，弄了个最基本的dmeo看看。
步骤如下：
1. web.xml配置：
1.1 首先定义spring的上下文：
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring.xml,classpath:spring-mybatis.xml</param-value>
</context-param>
加载监听器：
<listener> <description>spring监听器</description> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
这样在web项目启动之后，就会自动在加载classpath里定义的文件spring.xml和spring-mybatis.xml;
1.2 定义一个springMVC的servlet：DispatcherServlet
<servlet> <servlet-name>springMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <discription>spring mvc 配置文件</discription> <param-name>contextConfigLocation</param-name> <param-value>classpath: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>
springMVC默认的配置文件名是：[servlet-name]-servlet.xml，这里我自定义为spring-mvc.xml通过classpath文件位置
以上三个配置文件：spring.xml,spring-mybatis.xml,spring-mvc.xml都放在resources目录下
2. 配置一个JDBC的属性文件：config.properties
spring.xml:
主要代码如下：
<!-- cservice包(自动注入) --> <context:component-scan base-package="com.bx.service"/> <!-- 引入属性文件 --> <context:property-placeholder location="classpath:config.properties" /> <!-- <bean class="com.comm.util.PropertiesUtil" /> --> <!-- 任务扫描 --> <task:annotation-driven/>
spring-mybatis.xml里配置数据源，配置事务管理器，用拦截器方式配置事物
