使用Jersey访问REST资源和静态资源

Question

我想从JSP页面中使用一些静态资源(图像,js,css)作为Viewable

我不知道如何使用WebPageContentRegex

如果我使用servlet,我可以执行资源,但我无法访问静态文件
如果我使用过滤器,我可以访问静态文件,但我无法执行资源

你能帮我两个吗？

这是我的文件:

webapp
  |____ resources
  |       |____ css
  |       |____ images
  |       |____ js
  |
  |____ WEB-INF
          |____ jsp

这是我的web.xml文件:

<?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" 
     xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
                         http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

<display-name>test</display-name>

<servlet>
<servlet-name>REST</servlet-name>

<init-param>
  <param-name>com.sun.jersey.config.property.JSPTemplatesBasePath</param-name>
  <param-value>/WEB-INF/jsp</param-value>
</init-param>
<init-param>
  <param-name>com.sun.jersey.config.property.WebPageContentRegex</param-name>
  <param-value>(/resources/(css|images|js)/.*)|(/WEB-INF/jsp/.*\.jsp)</param-value>
</init-param>
</servlet>
<servlet-mapping>
  <servlet-name>REST</servlet-name>
  <url-pattern>/resources/*</url-pattern>
</servlet-mapping>

Answer 1

您可以验证您是否使用 jersey 1.x 吗？如果您使用的是 2.x，则应将 com.sun.jersey.config.property.WebPageContentRegex 替换为 jersey.config.servlet.filter.staticContentRegex

我可以问你是否也简化你的正则表达式，第一次只提供 *.html ？（可能是正则表达式的问题！）

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
                             http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
