Question

我正在尝试一个简单的Spring-MVC应用程序，它从用户那里获取输入并在屏幕上显示它。我是Spring-MVC的新手。我在浏览器上收到消息说：

"HTTP status 404:The requested resource is not available"

我正在尝试使用网址在浏览器上运行：

"http://localhost:8080/Spring_Test/admissionForm.html"

它没有在eclipse控制台上显示任何消息。我不确定天气我缺少任何jar文件或其他东西。在这里，我分享我的文件内容和jar文件。请帮我解决这个问题。

Jar文件：

commons-fileupload-1.2.2.jar
commons-io-1.3.2.jar
commons-logging-1.1.1.jar
jstl-1.1.2.jar
mysql-connector-java-5.1.34-bin.jar
spring-aop-3.0.6.RELEASE.jar
spring-asm-3.0.6.RELEASE.jar
spring-beans-3.0.6.RELEASE.jar
spring-context-3.0.6.RELEASE.jar
spring-context-support-3.0.6.RELEASE.jar
spring-core-3.0.6.RELEASE.jar
spring-expression-3.0.6.RELEASE.jar
spring-jdbc-3.2.9.RELEASE.jar
spring-web-3.0.6.RELEASE.jar
spring-webmvc-3.0.6.RELEASE.jar

的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

Spring_Test-servlet.xml中：

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

</beans>

控制器：

package com.leader;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.stereotype.*;

@Controller
public class StudentAdmissionController {

@RequestMapping(value="/Spring_Test/admissionForm.html", method=RequestMethod.GET)
public ModelAndView getAdmissionForm(){
    ModelAndView model = new ModelAndView("AdmissionForm");
    return model;
}

@RequestMapping(value = "/Spring_Test/submitAdmissionForm.html", method = RequestMethod.POST)
public ModelAndView submitAdmissionForm(@RequestParam("studentName") String name,@RequestParam("hobby") String hobby){

    ModelAndView model = new ModelAndView("AdmissionSuccess");
    model.addObject("msg", "hello");
    return model;

}

}

Answer 1

也许您在配置中忘记了<mvc:annotation-driven />以启用@Controller注释扫描，至少是它的样子

Answer 2

@RequestMapping（value =“/ admissionForm.html”，method = RequestMethod.GET）而不是在你的控制器中使用

@RequestMapping（value =“/ Spring_Test / admissionForm.html”，method = RequestMethod.GET）

Answer 3

尝试将web.xml中的url模式更改为/ *而不是/

错误：HTTP状态404：请求的资源不可用？
