Jboss 7.1中的RestEasy Jax-RS不起作用

Question

我正在尝试在JBoss AS 7.1下部署一个简单的Web应用程序,它与resteasy捆绑在一起.根据文档,所需要的只是(至少)是一个空的web.xml,一个带注释的类@ApplicationPath("/mypath")和@Path("/other_stuff")你的其他类

我关注的文档在这里:

• https://docs.jboss.org/author/display/AS7/JAX-RS+Reference+Guide
• https://docs.jboss.org/author/display/AS7/Java+API+for+RESTful+Web+Services+(JAX-RS)

当我点击时:

host:8080/warname/applicationpath/path

我在网页上收到404错误,但日志中没有任何内容.

是否需要更改配置文件才能使JAX-RS正常工作？

预先感谢您的任何帮助!

Answer 1

空的web.xml会做.

只需在类路径中添加一些resteasy依赖项.例如,如果你使用maven,你可以将它添加到你的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 {
}

只是为了确保添加这样的资源:

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

这就是你所需要的.在JBoss AS 7.1上部署它并进入它,说:

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

编辑:

我用最小的结构创建了一个java war maven项目:

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

我打电话给它simpleRest,如下所示.所有档案都如下所示:

pom.xml中:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
                        http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>simpleRest</groupId>
    <artifactId>simpleRest</artifactId>
    <version>1.0</version>
    <packaging>war</packaging>

    <dependencies>
        <dependency>
            <groupId>org.jboss.resteasy</groupId>
            <artifactId>resteasy-jaxrs</artifactId>
            <version>2.3.1.GA</version>
            <scope>provided</scope>
        </dependency>
    </dependencies>
<build>
    <finalName>${project.artifactId}</finalName>
    <plugins>
        <plugin>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.1.1</version>
            <configuration>
                <!-- So maven doesn't require web.xml -->
                <failOnMissingWebXml>false</failOnMissingWebXml>
            </configuration>
        </plugin>
    </plugins>
</build>
</project>

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();
    }
}

JaxRsActivator.java:

package rest;

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

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

}

这会产生一个simpleRest.war(通过mvn clean package).然后我将它部署到新安装的JBoss AS 7.1.1.Final.如您所见,在部署期间未在日志中引用JAX-RS:

22:48:08,677 INFO  [org.jboss.as.server.deployment] (MSC service thread 1-1) JBAS015876: Starting deployment of "simpleRest.war"
22:48:09,318 INFO  [org.jboss.web] (MSC service thread 1-4) JBAS018210: Registering web context: /simpleRest
22:48:09,492 INFO  [org.jboss.as.server] (DeploymentScanner-threads - 2) JBAS018559: Deployed "simpleRest.war"

之后,URL可按预期使用:

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

请注意,其他一切都会出现404错误.但它是另一种404.

http://127.0.0.1:8080/simpleRest/ 得到:

HTTP Status 404 - /simpleRest/

这是一个页面未找到错误.另一方面,http://127.0.0.1:8080/simpleRest/rest给出:

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.这样你知道JAX-RS正在运行,尽管它没有该路径的处理程序.
