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
