问题描述
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
,一个带有注释的类@ApplicationPath(/ mypath你的其他课程的)
和 @Path(/ other_stuff)
I'm trying to deploy a simple web application under JBoss AS 7.1 which comes bundled with resteasy. According to the documentation all that is needed is (at bare minimum) is an empty web.xml
, a class with annotated @ApplicationPath("/mypath")
and @Path("/other_stuff")
for your other classes
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)
但是,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。
I receive a 404 error on the webpage but nothing in the logs.
是否需要更改配置文件才能使JAX-RS正常工作?
Is there a configuration file I need to change in order for JAX-RS to work?
提前感谢您的帮助!
推荐答案
空 web.xml
将会这样做。
只需在你的类路径中添加一些resteasy依赖项。例如,如果您使用maven,则可以将其添加到 pom.xml
:
Just add some resteasy dependency to your classpath. For instance, if you use maven you can add this to your 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:
Then set up the application using only this class:
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
@ApplicationPath("/rest")
public class JaxRsActivator extends Application {
}
为了确保,添加如下资源:
Just to make sure, add a resource like this:
@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上部署并进入它,比如说:
And that's all you need. Deploy it at a JBoss AS 7.1 and get to it, say:
http://127.0.0.1:8080/mywarname/rest/hello
编辑:
I用最小的结构创建了一个java war maven项目:
I have created a java war maven project with the bare minimum strucutre:
-pom.xml
-src
|
--main
|
--java
|
--rest
|
--HelloResource.java
--JaxRsActivator.java
我叫它 simpleRest
,如下所示。所有档案都如下所示:
I called it simpleRest
as seen below. All the archives are exactly as shown:
pom.xml:
<?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
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:
JaxRsActivator.java:
package rest;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;
@ApplicationPath("/rest")
public class JaxRsActivator extends Application {
}
这会生成 simpleRest.war
(通过 mvn clean package
)。然后我将其部署到新安装的。如您所见,在部署期间未在日志中引用JAX-RS:
This generates a simpleRest.war
(through mvn clean package
). I then deploy it to a freshly installed JBoss AS 7.1.1.Final. As you can see, no reference is made to JAX-RS in the log during the deploy:
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,网址按预期显示:
After that, the URL is available as expected:
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.
Notice that everything else gives a 404 error. But it is a different kind of 404.
http://127.0.0.1:8080/simpleRest/
给出:
HTTP Status 404 - /simpleRest/
这是页面未找到错误。另一方面, http://127.0.0.1:8080/simpleRest/rest
给出:
That is a page not found error. On the other hand, http://127.0.0.1:8080/simpleRest/rest
gives:
HTTP Status 404 - Could not find resource for relative : / of full path: http://127.0.0.1:8080/simpleRest/rest
这是资源(REST服务)未找到错误。这样你知道JAX-RS正在运行,虽然它没有该路径的处理程序。
That is a resource (REST service) not found error. This way you know JAX-RS is acting, though it did not have a handler for that path.
