Jersey / * Servlet映射导致静态资源出现404错误

java

如果我在2.0版本中将Jersey的url-pattern映射到/ *,它将为所有静态资源(例如/index.html)造成404。我的web.xml具有:

<servlet>
  <servlet-name>JerseyApp</servlet-name>
  <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
  <init-param>
    <param-name>javax.ws.rs.Application</param-name>
    <param-value>org.frog.jump.JerseyApp</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>JerseyApp</servlet-name>
  <url-pattern>/*</url-pattern>
</servlet-mapping>

如何使用相同的网址格式投放静态内容?

使用Jersey 1.x,如果你从Jersey servlet切换到过滤器,则应该能够从同一路径提供静态内容。删除你指定的servlet XML并将其切换到:

<filter>
  <filter-name>Jersey Filter</filter-name>
  <filter-class>com.sun.jersey.spi.container.servlet.ServletContainer</filter-class>
  <init-param>
    <param-name>javax.ws.rs.Application</param-name>
    <param-value>org.frog.jump.JerseyApp</param-value>
  </init-param>
  <init-param>
    <param-name>com.sun.jersey.config.property.WebPageContentRegex</param-name>
    <param-value>/.*html</param-value>
  </init-param>
</filter> 
<filter-mapping>
  <filter-name>Jersey Filter</filter-name>
  <url-pattern>/*</url-pattern> 
</filter-mapping>

编辑:在Jersey 2.x中,你应该可以做相同的事情,但是属性名称已更改。尝试类似的东西:

<filter>
  <filter-name>Jersey Filter</filter-name>
  <filter-class>org.glassfish.jersey.servlet.ServletContainer</filter-class>
  <init-param>
    <param-name>jersey.config.server.provider.packages</param-name>
    <param-value>org.example</param-value>
  </init-param>
  <init-param>
    <param-name>jersey.config.servlet.filter.staticContentRegex</param-name>
    <param-value>/.*html</param-value>
  </init-param>
</filter> 
<filter-mapping>
  <filter-name>Jersey Filter</filter-name>
  <url-pattern>/*</url-pattern> 
</filter-mapping>

而且你的POM应该包括:

<dependency>
  <groupId>org.glassfish.jersey.core</groupId>
  <artifactId>jersey-server</artifactId>
  <version>2.0-m07-1</version>
  <type>jar</type>
  <scope>compile</scope>
</dependency>

<dependency>
  <groupId>org.glassfish.jersey.containers</groupId>
  <artifactId>jersey-container-servlet-core</artifactId>
  <version>2.0-m07-1</version>
  <type>jar</type>
  <scope>compile</scope>
</dependency>

如果要提供CSS,JSP等服务,则必须在init-param中自定义正则表达式。

另一个不错的选择是为你的服务使用版本路径(“ / v1 / *”),然后静态内容将在没有过滤器的情况下工作。
