1.导入必要的SpringMVC JAR包
2.在web.xml中配置SpingMVC的加载项
<servlet>//SpringMVC配置加载项的方式为在web.xml中定义其加载的servlet
<servlet-name>springMVC</servlet-name>//Servlet名称
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
//Servlet对应的class路径
<init-param>//servlet的启动项
<param-name>contextConfigLocation</param-name>//启动项的名称
<param-value>classpath*:config/springAnnotation-servlet.xml</param-value>
//classpath*：表示在所有路径下加载
//启动项的值，表示SpringMVC的配置文件为springAnnotation-servlet.xml
//如果不配置此启动项，则默认寻找WEB-INF目录下名称为 [<servlet-name>]-servlet.xml，如springMVC-servlet.xml
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springMVC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
3.在src下建立config文件夹，在其中编写springAnnotation-servlet.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!--<bean name="/test1/helloworld" class="com.tgb.web.controller.HelloWorldController" /> -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
<mvc:resources location=”/img/” mapping=”/img/**”/>这样就可以访问img下的静态文件。
//配置多方法Controller需在SpringMVC配置文件中添加：
<bean name="/test1/multi" class="com.tgb.web.controller.MultiController">
<property name="methodNameResolver">
<ref bean="paramMethodResolver"/>
</property>
</bean>
<bean id="paramMethodResolver" class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
<property name="paramName" value="action"></property>//value为解析的请求路径
</bean>
Java文件为：
public class MultiController extends MultiActionController {
public ModelAndView add(HttpServletRequest request,HttpServletResponse response){
System.out.println("---add---");
return new ModelAndView("/multi","method","add");
}
public ModelAndView update(HttpServletRequest request,HttpServletResponse response){
System.out.println("---update---");
return new ModelAndView("/multi","method","update");
}
启动注解时删除配置的bean和在配置多方法Controller需在SpringMVC配置文件中添加的代码，把SpringMVC的配置文件修改为如下：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!-- 配置扫描包，启动服务器时需要扫描的包 -->
<context:component-scan base-package="com.tgb.web.controller"></context:component-scan>
<!-- 配置启动注解所需的两个bean -->
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"></bean>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
