Question

我有一个带有宁静的Web服务API的Web应用程序。该应用程序现已开发并在Glassfish Server（3.1.x）上完美运行。

作为jax-rs的实现，webapp使用Rest-easy，因为现有的功能在泽西岛没有。

现在，有必要在WebLogic 12c中部署Web应用程序，特别是在weblogic 12.1.2中。但似乎不可能这样做。 Weblogic使用Jersey来提供宁静的服务，并且如果要使用不同的实现jax-rs则会产生冲突。那么问题是......是否可以使用不同的JAX-RS Jersey实现。（在我看来是RestEasy）。

尽管如此，web.xml存档配置为使用RestEasy Servlet，仍然显示错误，如使用泽西（<BEA-101216> <Servlet: "Jersey" failed to preload on startup in Web application: "pruebaRestWL-1.0-SNAPSHOT") and ( <Error> com.sun.jersey.spi.inject.Errors>）。

错误是：

web.xml （这是Resteasy在GF中工作所需的配置）

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <context-param>

        <param-value>true</param-value>
    </context-param>
    <listener>
        <listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class>
    </listener>
    <servlet>
        <servlet-name>Resteasy</servlet-name> <!-- Servlet for use RestEasy -->
        <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>Resteasy</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>
    <context-param>
        <param-name>resteasy.servlet.mapping.prefix</param-name>
        <param-value>/services</param-value>
    </context-param>
</web-app>

我尝试的方法之一是禁用了WebLogic上的Jersey。我尝试在ORACLE_HOME / oracle_common / modules中删除用于weblogic的jersey库。

Jersey的客户端 - 1.17.1
球衣核-1.17.1
Jersey的JSON-1.17.1
Jersey的多-1.17.1
球衣 - 服务器 - 1.17.1
Jersey的servlet的1.17.1

但我有这个错误：weblogic.application.ModuleException：java.lang.ArrayStoreException：sun.reflect.annotation.TypeNotPresentExceptionProxy

<17/12/2013 10:07:15 AM CST> <Error> <Deployer> <BEA-149265> <Failure occurred in the execution of deployment request with ID "1387296431330" for task "0". Error is: "weblogic.application.ModuleException: java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy"

编辑： 仅使用一个Restful服务共享一个maven项目并配置为使用RestEasy。该项目在GF工作。

可以使用de follow URI进行测试。 GET。

    Here is working solution on WebLogic 12.2.1 and WebLogic 10.3.6

    Changes in pom.xml
         <dependency>
            <groupId>org.jboss.resteasy</groupId>
            <artifactId>resteasy-jaxrs</artifactId>
            <version>2.2.1.GA</version>

         </dependency>

    Changes in web.xml
        <!-- A comma delimited list of fully qualified JAX-RS resource class names you want to register -->
        <!-- And don't use resteasy.scan=true -->
        <context-param>
            <param-name>resteasy.resources</param-name>
            <param-value>com.***.RestServiceClass</param-value>
        </context-param>

        <!-- This is needed if the url-pattern for the Resteasy servlet-mapping is not /* -->
        <context-param>
            <param-name>resteasy.servlet.mapping.prefix</param-name>
            <param-value>/rest</param-value>
        </context-param>

        <listener>

                org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap

        </listener>

        <servlet>

            <url-pattern>/rest/*</url-pattern>
        </servlet-mapping>

@Stateless
@Path("/test")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class RestServiceClass
{
   @POST
   @Path("/doJob1")
   @GZIP
   public String doJob1()
   {
      return "Ok";
   }
...

Answer 2

可以部署RESTeasy并使用它。务必设置weblogic.xml correctly so to isolate the classpath。没有必要，事实上你不应该禁用Jersey模块。

WebLogic12c上的Resteasy（或不是Jersey - JAXRS实现）是否可行？
