Question

我无法让我的控制器在我的Spring Web MVC应用程序中响应我的HTTP请求。该项目将部署，但只会加载默认的＆quot; index.jsp＆＃39;文件。我相信我的问题可能在context.xml文件中，但我不确定如果问题是如何正确配置文件。

项目结构：

-src /主/爪哇/控制器/ projectGitControllers

-src /主/ web应用/ WEB-INF /配置/ projectGit-servletConfig.xml

-src /主/ web应用/ WEB-INF /页/ homepage.jsp

我正在尝试使用的网址

- http://localhost:8080/projectGit/getHomepage

的web.xml

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

</beans>

Answer 1

您的@Controller班级有package controllers;

你有

base-package="com.application.projectGit.controllers"

因此，您的@Controller永远不会创建一个bean。

因此从package controllers;更改为package com.application.projectGit.controllers;

注意：是一种不好的做法，使用包名称的大写字符

添加01：

自：

<bean id="viewResolver"  
      class="org.s....InternalResourceViewResolver" 
      p:prefix="WEB-INF/pages/" 
      p:suffix=".jsp" />

将p:prefix="WEB-INF/pages/"更新为p:prefix="/WEB-INF/pages/"。因此现在是/WEB-INF，它以/

开头

Answer 2

您的viewResolver指向WEB-INF/jsp/

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="WEB-INF/jsp/" p:suffix=".jsp" />

而您的jsp位于WEB-INF/pages

下

src/main/webapp/WEB-INF/pages/homepage.jsp
