Question

当我运行SpringWebApplication（localhost：8008 / SpringWebApplication /）时，我期待渲染welcome-file。

但它正在抛出404

有人可以告诉我我是否缺少任何配置。我是否需要一个Controller来访问welcome-file？或者可以在没有控制器的情况下访问文件。

以下是我的应用程序SpringWebApplication中的文件。

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" 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">
  <display-name>SpringWebApplication</display-name>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

  <servlet>
        <servlet-name>springWeb</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
      <servlet-name>springWeb</servlet-name>
      <url-pattern>/*</url-pattern>
  </servlet-mapping>

   <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/springWeb-servlet.xml</param-value>
   </context-param>

    <listener>
       <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

的index.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Index Page</title>
</head>
<body>
Index Page
</body>
</html>

springWeb-servlet.xml中

<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"

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
      <property name="prefix" value="/" />
      <property name="suffix" value=".jsp" />
    </bean>

</beans>

控制台

Answer 1

尝试在配置文件中添加以下内容：

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

Answer 2

在DispatcherServlet的<url-pattern>/</url-pattern>中尝试<url-pattern>/*</url-pattern>而不是servlet-mapping。

<servlet-mapping>
    <servlet-name>springWeb</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

无法使用Spring </welcome-file>访问<welcome-file>
