Spring MVC：无法映射子文件夹下的 JSP 文件答案

【问题标题】：Spring MVC: Cannot mapping JSP files under subfoldersSpring MVC：无法映射子文件夹下的 JSP 文件
【发布时间】：2017-09-30 16:05:16
【问题描述】：

我知道有很多主题有相同的问题，但经过 3 天的研究，我无法解决我的问题。

如果有人在其他地方发现了答案，请随时将其标记为重复并引导我到那里。

我正在尝试在我的控制器中映射一个请求，然后重定向到我的默认视图文件夹下的子文件夹。但是，我收到 404 错误。

我的 web.xml：

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

我的 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"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"

    xsi:schemaLocation="http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/task
    http://www.springframework.org/schema/task/spring-task.xsd">

    <context:component-scan base-package="br.com.sigcom.controller" />

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

    <mvc:annotation-driven />

    <mvc:resources mapping="/resources/**" location="/resources/" cache-period="31556926" />
  </beans>

如您所见，我的默认视图文件夹是 WEB-INF/views。到目前为止，一切都很好。我做了一个这样的子文件夹：

WEB-INF/
  |-views/
    |-admin/
      |-default.jsp

在我的控制器中，我无法访问 WEB-INF/views/admin/default.jsp，因为我收到了这个 404 错误。

我的控制器：

package br.com.sigcom.controller;

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

@Controller

public class SpringController { 
  @RequestMapping(value = {"", "/", "home", "default", "index"})
  public String redirectDefaultPage() {
    return "default";
  }

  @RequestMapping("admin")
  public String redirectAdminPage() {
    return "admin/default";
  }
}

我尝试了很多，搜索了很多，但是没有成功。我知道这一定是一个简单的细节，但我已经筋疲力尽了。提前谢谢！

PS.：我的控制台：

【问题讨论】：

标签： java spring jsp servlets subdirectory

【解决方案1】：

我尝试使用与您相同的设置设置一个项目，只是 web.xml 中没有过滤器、过滤器映射、错误页面、侦听器，并且我能够在没有 404 的情况下访问 URL。

控制器也能够解析模板。您是否也使用上下文路径正确输入了您的 URL？例如http://localhost:8080/SIGCOM/admin

【讨论】：

您的其他配置设置一定有问题，因为在这里创建相同的项目有效。或许，你可以试试把最小的包上传到git，让我们看看？
已解决，@Chris。这是我的过滤器！

【解决方案2】：

我已经使用您的代码创建了一个新项目。但最后，我得到了正确的东西。也许你可以像一楼说的那样检查你的网址。

【讨论】：

再次检查...没有。

【解决方案3】：

已解决。当你们没有过滤器运行时，我已经评论了我的并工作了。现在我知道该怎么做了。感谢您的帮助，伙计们！
