Question

我是春季新手，试图获取home.jsp，但没有成功。我试图在这里和那里进行一些研究以解决此问题，但仍在home.jsp上得到404

我正在使用sts 3.9.3-RELEASE和Pivotal tc Server Developer Edition v3.2

我做了什么：

-在部署proyect时放置依赖项。

junit-3.8.1.jar spring-webmvc-5.0.7.RELEASE.jar。
spring-aop-5.0.7.RELEASE.jar spring-beans-5.0.7.RELEASE.jar。
spring-context-5.0.7.RELEASE.jar spring-core-5.0.7.RELEASE.jar。
spring-jcl-5.0.7.RELEASE.jar spring-expression-5.0.7.RELEASE.jar。
spring-web-5.0.7.RELEASE.jar slf4j-api-1.7.25.jar。

-获得servlet名称，但始终打印“ jsp”。 -更新了Maven几次。 -将jre库更改为jre 1.8.0_171

路径：/webapp/WEB-INF/views/home.jsp，/webapp/WEB-INF/web.xml和/webapp/WEB-INF/example-servlet.xml

服务器启动时，我可以通过/webapp/WEB-INF/index.jsp来获取信息。

web.xml：

<?xml version="1.0" encoding="UTF-8"?>
 <web-app id="WebApp_ID" version="3.1"
    xmlns="http://xmlns.jcp.org/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">
<servlet>
    <servlet-name>example</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>example</servlet-name>
    <url-pattern>*.html</url-pattern>
</servlet-mapping>

example-servlet.xml：

<?xml version="1.0" encoding="UTF-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
    http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">

<context:component-scan base-package="com.jp.holaspringmvc.controller"/>
<mvc:annotation-driven/>
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/views/</value>
        </property> 
        <property name="suffix">
            <value>.jsp</value>
        </property> 
    </bean>
  </beans>

HomeController.java：

package com.jp.holaspringmvc.controller;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
public class HomeController {


  private static final Logger log =  LoggerFactory.getLogger(HomeController.class);

  @RequestMapping(value="/home", method=RequestMethod.GET)
  public String goHome() {
    log.debug("mensaje del controller");
    return "home";
  }
}

/webapp/WEB-INF/views/home.jsp：

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
