处理方法返回值void

1、默认响应效果：根据请求url寻找相应页面

1.1、配置的视图解析器

    <!--配置视图解析器-->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

1.2、假定占位符的值为1，则会寻找/WEB-INF/pages/demo/test/1.jsp页面

package com.ly.mvc.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/demo")
public class DemoController {
    @RequestMapping("/test/{1}")
    public void test1() {
        System.out.println("test");
    }
}

1.3、会寻找/WEB-INF/pages/demo/test.jsp页面

package com.ly.mvc.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/demo")
public class DemoController {
    @RequestMapping("/test")
    public void test1() {
        System.out.println("test");
    }
}
