Spring Tomcat和静态资源以及mvc：资源 [英] Spring Tomcat and static resources and mvc:resources

问题描述

我从头开始做一个网络应用程序。在我一直在处理已经运行很长时间的应用程序之前，所以我没有必要处理完整的设置阶段。我正在使用Spring 3和Tomcat 6，而我正在使用Eclipse 3.6

I started doing a web app from scratch. Before I've always been working on apps that were already running for a long time, so I didn't have to deal with the full setup phase. I am using Spring 3 and Tomcat 6, and I am using Eclipse 3.6

我在提供图像（或其他与控制器响应不同的事情）方面存在很大问题。事实上，我无法找到一种方法将我的图像放在我的jsps中。我的配置适用于：

I've a big problem with serving images (or other things different from controller responses). In fact I can't find a way to have my images in my jsps. My configuration, works with:

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

在web.xml中

<bean name="/accise" class="it.jsoftware.jacciseweb.controllers.MainController">

</bean>

用于servlet上下文（当然还有其他）。

for the servlet context (plus other of course).

我在这里和其他论坛上读到了很多消息：

I've read many messages here and other forums talking about this:

<mvc:resources mapping="/resources/**" location="/resources/" />

但是如果我在我的servlet-context.xml中插入它，我将能够提供图像，然而控制器accise将无法访问。我误用了还是误解了资源标签？什么是正确的方法？

but if I insert that in my servlet-context.xml, I will be able to serve images, yet the controller "accise" won't be reachable. Am I misusing or I misunderstood the resources tag? What's the correct way?

找到更新解决方案!!! ：）

问题是我的servlet-config.xml错过了一个声明：

The problem was that my servlet-config.xml missed one declaration:

现在它是（在控制器上使用注释）：

Now it is(using annotations on the controller):

<?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:mvc="http://www.springframework.org/schema/mvc"

    <context:component-scan base-package="it.jsoftware.jacciseweb.controllers"></context:component-scan>
    <mvc:annotation-driven />

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

<mvc:resources mapping="/resources/**" location="/resources/" />

推荐答案

< mvc：resources> 可以使用带注释的控制器，但可能需要对其他类型的控制器映射进行额外配置。

<mvc:resources> plays well with annotated controllers, but may require some extra configuration with other kinds of controller mappings.

我想在你的情况下你需要手动声明 BeanNameUrlHandlerMapping （它通常默认注册，但是< mvc：resources> 覆盖默认值作为应用其自身配置的副作用）：

I guess in your case you need to declare BeanNameUrlHandlerMapping manually (it's usually registered by default, but <mvc:resources> overrides defaults as a side-effect of applying its own configuration):

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