带有Jersey的JAX-RS在JBoss AS中不起作用 [英] JAX-RS with Jersey not working in JBoss AS
本文介绍了带有Jersey的JAX-RS在JBoss AS中不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试将简单的REST服务上传到JBoss AS 7.1(或TomEE JAX-RS)上.
I'm trying to upload simple REST service onto JBoss AS 7.1 (or TomEE JAX-RS).
我的web.xml:
<servlet>
<servlet-name>jersey-serlvet</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>com.javacodegeeks.jersey.main</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jersey-serlvet</servlet-name>
<url-pattern>/rs/*</url-pattern>
</servlet-mapping>
对pom.xml的依赖性:
<dependency>
<groupId>javax.ws.rs</groupId>
<artifactId>javax.ws.rs-api</artifactId>
<version>2.0.1</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-server</artifactId>
<version>1.9</version>
</dependency>
服务器端点:
@Path("account")
public class AccountDetailsService {
@GET
@Path("/details/{param}")
@Produces(MediaType.TEXT_PLAIN)
public Response getAccountDetails(@PathParam("param") String accountName) {
String output = "Account Name : " + accountName;
return Response.status(200).entity(output).build();
}
}
但我收到此错误:

如果同样在Tomcat 7容器上工作正常，为什么会发生这种情况?
Why does it happen if the same works fine on Tomcat 7 container?

推荐答案
解决方案不是很明显...
The solution was quite non-obvious...
1)以下行已添加到web.xml:
1) The following lines was added to web.xml:
<context-param>
<param-name>resteasy.scan</param-name>
<param-value>false</param-value>
</context-param>
<context-param>
<param-name>resteasy.scan.providers</param-name>
<param-value>false</param-value>
</context-param>
<context-param>
<param-name>resteasy.scan.resources</param-name>
<param-value>false</param-value>
</context-param>
2)注释掉了来自web-xml的以下几行:
2) Next lines from web-xml was commented out:
<!--<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.javacodegeeks.jersey.main</param-value>
</init-param>-->
3)无需创建 jboss-deployment-structure.xml 或编辑 standalone.xml .
3) No need to create a jboss-deployment-structure.xml or edit standalone.xml.
