SpringMVC 控制器写多个方法（非注解方式）

Controller类有两种方法

1，implements Controller（实现Controller接口）

2，extends MultiActionController（继承 MultiActionController）

但是实现接口有缺陷，只能写一种方法（handleRequest），比如完成某一业务对象的增，删，改，查，都属于一类相关的业务。把一类相关的操作分布到不同的类去完成，违返“高内聚”的设计原则。所以一般都会采用第二种方法。

springmvc-servlet.xml

        <property name="prefix" value="/page/" />
        <property name="suffix" value=".jsp" />
    </bean>
    
    <!--  MultiAction -->
    <!-- 引入多视图控制 -->
    <bean id="paramMethodResolver"
        class="org.springframework.web.servlet.mvc.multiaction.ParameterMethodNameResolver">
        <property name="paramName" value="method">
        </property>
    </bean>
    <bean id="simpleUrlHandlerMapping"
        class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="/testinterceptor">testInterceptorController</prop>
            </props>
        </property>
    </bean>
    <!-- 将多视图控制paramMethodResolver注入到自己的控制器--> 
    <bean id="testInterceptorController" class="com.TestInterceptorController">
        <property name="methodNameResolver" ref="paramMethodResolver"></property>
    </bean>
    
</beans>

控制器：

package com;

import java.util.Date;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.mvc.multiaction.MultiActionController;

@SuppressWarnings("deprecation")
public class TestInterceptorController extends MultiActionController {

    public String show(HttpServletRequest request, HttpServletResponse response){
        request.setAttribute("date", new Date());
        return "show";
    }
}

*这里要用request进行传值

输入访问：......?method=show
