Question

我正在制作一个简单的Spring MVC Hello World项目。但是，我对URL中jsp文件的映射存在一些小问题。每当我致电http://localhost:8080/SalesManagement/welcome时，它都会返回404 Error。我已经尝试过在所提出的一些相同问题中所说的所有内容，但我仍然无法使其成功运行。这是我的代码：

package com.salesmanagement.web;

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


@Controller
public class HelloWorldController {

    @RequestMapping("/welcome")
    public ModelAndView helloWorld() {

        String message = "<br><div style='text-align:center;'>"
                + "<h3>********** Hello World, Spring MVC Tutorial</h3>This message is coming from CrunchifyHelloWorld.java **********</div><br><br>";
        return new ModelAndView("welcome", "message", message);
    }
}

销售-servlet.xml中

我的项目名称是SalesManagement。我在webContent / WEB-INF文件夹中有我的index.jsp，而我的welcome.jsp在WebContent / WEB-INF / jsp文件夹中。我尝试添加<mvc:annotation-driven />标记，但它仍无效。

更新此评论这对我有用销售-servlet.xml中

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"

            <property name="viewClass"

            <property name="prefix" value="/WEB-INF/jsp/" />
            <property name="suffix" value=".jsp" />
        </bean>
    </beans>

Answer 2

        you can use this viewResolver.
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
              <property name="prefix" value="/WEB-INF/jsp/" />
              <property name="suffix" value=".jsp" />
        </bean>

use **spring 3.1.1** version jar file into pom.xml
and create welcome.jsp file and print ${message}
