405错误获取资源

Question

我有一个Spring MVC应用程序，每当我请求资源时，我都会收到405错误。

我在我servlet.xml文件如下：

<context:component-scan base-package="com.xetius"/> 

<mvc:annotation-driven/> 

<mvc:resources mapping="/images/**" location="classpath:/images/"/> 
<mvc:resources mapping="/thumbs/**" location="classpath:/thumbs/"/> 
<mvc:resources mapping="/gallery/**" location="classpath:/gallery/"/> 
<mvc:resources mapping="/style/**" location="classpath:/style/"/> 
<mvc:resources mapping="/script/**" location="classpath:/script/"/> 
<mvc:resources mapping="/downloads/**" location="classpath:/downloads/"/> 

<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" /> 

<bean id="viewResolver" 
     class="org.springframework.web.servlet.view.UrlBasedViewResolver"> 
    <property name="viewClass"> 
     <value>org.springframework.web.servlet.view.tiles2.TilesView</value> 
    </property> 
</bean> 

<bean class="org.springframework.web.servlet.view.tiles2.TilesConfigurer"> 
    <property name="definitions"> 
     <list> 
      <value>/WEB-INF/views/**/views.xml</value> 
     </list> 
    </property> 
</bean> 

，在我回到Home.jsp文件我有以下几点：

<img class="about" src="/images/about.jpg" alt="about" /> 

当我运行这个使用Tomcat7所有里面的IntelliJ资源正在返回405方法不允许。下面是该请求的HAR

    }, 
    "pageref": "page_1" 
} 

当我检查WAR文件时，具体文件位于WEB-INF/classes/images内。

我一定错过了一些东西，但是这让我疯狂。有人有主意吗？

编辑 -

我已经包括了我在这里的web.xml文件：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 
    <display-name>a-Form Catering</display-name> 
    <description>a-Form Catering Web Site</description> 

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

    <servlet-mapping> 
     <servlet-name>a-form</servlet-name> 
     <url-pattern>/</url-pattern> 
    </servlet-mapping> 

</web-app> 

我的servlet文件实际上是一个外形servlet.xml中

Answer 1

这可能是你错过了您在url中的应用背景

<img class="about" src="/WEBAPP_CONTEXT/images/about.jpg" alt="about" /> 

如果您没有任何明确的上下文配置，那么我认为它是没有.war扩展名的WAR文件的名称。

您也可以在JSP中使用JSTL核心URL标记来引用资源。

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> 
    .......................... 

<img class="about" src="<c:url value="/images/about.jpg"/>" alt="about" /> 

在这种情况下，您不需要指定上下文。

Answer 2

您的web.xml有没有可疑的产品？如果不是，我有一个预感，它可能是UrlBasedViewResolver劫持你的图像。你可以尝试添加viewNames属性来限制它解决，如：

<bean id="viewResolver" class="....UrlBasedViewResolver"> 
    ... 
    <property name="viewNames" value=".jspwhatever" /> 
</bean> 

（或重合prefix和/或suffix属性）。

希望有所帮助。

干杯，

我敢肯定，这已得到修复，但如果其他人有同样的问题。我通过更改<url-pattern>以*结尾来解决类似问题。这应该将DispatcherServlet映射到每个路径。如下所示：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" 
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> 
    <display-name>a-Form Catering</display-name> 
    <description>a-Form Catering Web Site</description> 

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

    <servlet-mapping> 
     <servlet-name>a-form</servlet-name> 
     <url-pattern>/*</url-pattern> 
    </servlet-mapping> 

</web-app>
