java - Jersey 服务 + PrettyFaces 冲突

Question

我的应用程序有一个正在运行的 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>

PrettyFaces 也做了一些 URL 重写，使用以下规则(来自 pretty-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>

请注意，规则不适用于 /rest/ 路径，但这不起作用。从我的浏览器到达其余路径时，抛出以下异常:

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

阅读异常我猜过滤器也适用于所有其他路径，而 Jersey 似乎不喜欢它。我该如何解决这个冲突？

如果您仔细查看异常，您会看到:

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

这看起来像是类路径问题。可能的原因是:

• 您的 WAR 中有 JAX-RS API 并将其部署到 Java EE 服务器。您应该从 WAR 中删除 API 或将范围更改为 provided。
• 您的类路径上有多个版本的 JAX-RS API，并且正在部署到 Tomcat 或 Jetty 等普通 servlet 容器。

希望对您有所帮助。
