Jboss 7.1中的RestEasy Jax-RS不起作用

Question

我试图在JBoss AS 7.1下部署一个简单的web应用程序，该应用程序与Resteasy捆绑在一起。根据文档，只需要（至少）一个空的web.xml、一个带有注释的@applicationpath（“/mypath”）和其他类的@path（“/other_stuff”）的类

下面是我所遵循的文档：

• https://docs.jboss.org/author/display/as7/jax-rs+reference+guide
• https://docs.jboss.org/author/display/as7/java+API+for+RESTful+Web+服务+(JAX-RS)

不过，当我击中：

host:8080/warname/applicationpath/path

提前感谢您的任何帮助！

Answer 1

只需向类路径添加一些resteasy依赖项即可。例如，如果使用maven，可以将其添加到pom.xml:

<dependency>
    <groupId>org.jboss.resteasy</groupId>
    <artifactId>resteasy-jaxrs</artifactId>
    <version>2.3.1.GA</version>
    <scope>provided</scope> <!-- provided if youre deploying to jboss as 7.1 -->
</dependency>

然后仅使用此类设置应用程序：

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("/rest")
public class JaxRsActivator extends Application {
}

为了确保这一点，添加一个资源，如下所示：

@Path("/hello")
public class HelloResource {
    @GET
    @Produces("text/plain")
    public String helloResource() {
        return "Hello! It's "+new Date();
    }
}

http://127.0.0.1:8080/mywarname/rest/hello

-pom.xml
-src
 |
  --main
    |
     --java
       |
        --rest
          |
           --HelloResource.java
           --JaxRsActivator.java

我称之为simplerest，如下所示。所有档案都如图所示：

HelloResource.java

package rest;

import java.util.Date;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;

@Path("/hello")
public class HelloResource {
    @GET
    @Produces("text/plain")
    public String helloResource() {
        return "Hello! It's "+new Date();
    }
}

package rest;

import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

@ApplicationPath("/rest")
public class JaxRsActivator extends Application {

}

http://127.0.0.1:8080/simpleRest/rest/hello

HTTP Status 404 - /simpleRest/

这是一个找不到页的错误。另一方面，http://127.0.0.1:8080/simpleRest/rest提供：

HTTP Status 404 - Could not find resource for relative : / of full path: http://127.0.0.1:8080/simpleRest/rest

这是一个资源（REST服务）未找到错误。这样，您就知道JAX-RS正在起作用，尽管它没有该路径的处理程序。
