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。

我的servlet.xml文件中包含以下内容：

<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>

在我的home.jsp文件中，我有以下内容：

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

当我使用Tomcat7在IntelliJ内部运行时，所有资源都被返回为405 Method Not Allowed。以下是该请求的HAR

当我检查WAR文件时，特定文件位于WEB-INF / classes / images。

我一定错过了什么，但这让我发疯了。有人有什么想法吗？

修改 -

我在这里包含了我的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a-form-servlet.xml

Answer 1

您可能错过了网址

中应用程序的上下文

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

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

您还可以在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，您无需指定上下文。

Answer 2

web.xml中是否有任何可疑之处？如果没有，我预感到可能是UrlBasedViewResolver劫持你的图像。您可以尝试添加viewNames属性来限制其解析的内容，例如：

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

（或一致prefix和/或suffix属性。）

希望有所帮助。

干杯，

Answer 3

我确信这已经修复，但是如果其他人遇到同样的问题。我通过将<url-pattern>更改为以*结尾来修复类似问题。这应该将DispatcherServlet映射到每个路径。见下文：

    <?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>
