泽西服务+ PrettyFaces冲突

Question

我的应用程序运行了一个RESTFul web服务。

<servlet>
    <servlet-name>jersey-servlet</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>com.sun.jersey.config.property.packages</param-name>
        <param-value>org.okkam.sameauthor.api</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>jersey-servlet</servlet-name>
    <url-pattern>/rest/*</url-pattern>
</servlet-mapping>

此外，PrettyFaces还使用以下规则进行了一些URL重写(来自漂亮的config.xml配置文件)

<url-mapping id="home">
    <pattern value="/" />
    <view-id value="/index.xhtml" />
</url-mapping>

<url-mapping id="demo">
    <pattern value="/demo" />
    <view-id value="/demo.xhtml" />
</url-mapping>

<url-mapping id="notfound">
    <pattern value="/notfound" />
    <view-id value="/notfound.xhtml" />
</url-mapping>

<url-mapping id="stop">
    <pattern value="/stop" />
    <view-id value="/stop.xhtml" />
</url-mapping>

注意，规则并不应用于/rest/路径，但是这是行不通的。当从我的浏览器到达rest路径时，将引发以下异常：

    SEVERE: Servlet.service() for servlet [jersey-servlet] in context with path [/sameauthor] threw exception [Servlet execution threw an exception] with root cause

读取异常时，我猜过滤器也适用于所有其他路径，而泽西岛似乎不喜欢它。我该如何解决这场冲突？

Answer 1

如果您仔细查看异常，您将看到以下内容：

java.lang.AbstractMethodError:
 javax.ws.rs.core.UriBuilder.uri(Ljava/lang/String;)Ljavax/ws/rs/core/UriBuilder;

这看起来像是一个类路径问题。可能的原因是：

• WAR中有Java，并将其部署到Java服务器上。您应该从WAR中删除API，或者将作用域更改为provided。
• 您的类路径上有多个版本的JAX，并且部署到一个普通的servlet容器中，比如Tomcat或Jetty。

我希望这能帮到你。
