REST 服务不会在 jboss AS 7 中加载答案

【问题标题】：REST services does'n load in jboss AS 7REST 服务不会在 jboss AS 7 中加载
【发布时间】：2018-03-23 14:54:49
【问题描述】：

我正在尝试使用 JBOSS AS7 制作一些 REST 服务，但是当我尝试访问它们时，日志显示 404。
我一直在寻找解决方案，但没有找到解决方案。
这些服务位于 WAR 项目中，该项目位于 EAR 文件中以在 JBOSS 中进行部署。

我正在使用 CXF 和 CDI 来提供服务。
JBOSS 有 EasyRest 3.0.5 版本。

这是WAR项目的pom.xml：

这是 EAR 包的 pom.xml，它引用了一个 JAR，因为在我发现关于使用 maven 制作 EAR 的教程中，它说要使用它，但没有任何内容：

<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/xsd/maven-4.0.0.xsd">

  <build>
    <finalName>projectEar</finalName>
  </build>
</project>

这个类被命名为 PeopleRestService 并具有以下服务：

package com.example.rs;

import java.util.Collection;

import javax.inject.Inject;
import javax.ws.rs.DELETE;
import javax.ws.rs.DefaultValue;
import javax.ws.rs.FormParam;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.UriInfo;

import com.example.model.Person;
import com.example.services.PeopleService;

@Path( "/people" )
public class PeopleRestService {


@Inject private PeopleService peopleService;

    @Produces( { MediaType.APPLICATION_JSON } )
    @GET
    public Collection< Person > getPeople( @QueryParam( "page") @DefaultValue( "1" ) final int page ) {
        return peopleService.getPeople( page, 5 );
    }

    @Produces( { MediaType.APPLICATION_JSON } )
    @Path( "/{email}" )
    @GET
    public Person getPerson( @PathParam( "email" ) final String email ) {
        return peopleService.getByEmail( email );
    }

    @Produces( { MediaType.APPLICATION_JSON  } )
    @POST
    public Response addPerson( @Context final UriInfo uriInfo,
            @FormParam( "email" ) final String email, 
            @FormParam( "firstName" ) final String firstName, 
            @FormParam( "lastName" ) final String lastName ) {

        final Person person = peopleService.addPerson( email, firstName, lastName );
        return Response.created( uriInfo.getRequestUriBuilder().path( email ).build() ).entity( person ).build();
    }

    @Produces( { MediaType.APPLICATION_JSON  } )
    @Path( "/{email}" )
    @PUT
    public Person updatePerson(         
            @PathParam( "email" ) final String email, 
            @FormParam( "firstName" ) final String firstName, 
            @FormParam( "lastName" )  final String lastName ) {

        final Person person = peopleService.getByEmail( email );

        if( firstName != null ) {
            person.setFirstName( firstName );
        }

        if( lastName != null ) {
            person.setLastName( lastName );
        }

        return person;              
    }

    @Path( "/{email}" )
    @DELETE
    public Response deletePerson( @PathParam( "email" ) final String email ) {
        peopleService.removePerson( email );
        return Response.ok().build();
    }
}

这被命名为 JaxRsApiApplication：

package com.example.rs;

import java.util.Arrays;
import java.util.HashSet;
import java.util.Set;

import javax.enterprise.inject.Produces;
import javax.inject.Inject;
import javax.ws.rs.ApplicationPath;
import javax.ws.rs.core.Application;

import com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider;

@ApplicationPath( "api" )
public class JaxRsApiApplication extends Application {

}

这是 beans.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee 
       http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
       bean-discovery-mode="all">
</beans>

这是 web.xml：

<!DOCTYPE web-app PUBLIC

 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>

    <servlet-mapping>
        <servlet-name>PeopleRestService</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>

</web-app>

当我尝试在 tomcat 中运行它时效果很好，但在 JBOSS 中只能得到 404。
我认为可能是图书馆的问题，但不知道具体是什么问题。

如果有人知道会发生什么，那将是一个很大的帮助。非常感谢，如果我的英语不好，请见谅。

祝你有美好的一天。

更新

但它现在给了我以下错误：

原因：java.lang.ClassNotFoundException: org.apache.cxf.cdi.CXFCdiServlet from [Module "deployment.projectEar.ear.projectWARModule-0.0.1-SNAPSHOT.war:main" from Service Module Loader]

【问题讨论】：

同一个耳朵在tomcat中工作，但在jboss中不工作，对吧？
为什么要导入 JavaEE API 部分（焊接、CXF）的所有实现。让应用服务器决定使用哪个，您只需将 javaee-api 工件（包含所有接口定义）添加到具有 provided 范围的根项目中。
@yılmaz .war 在 tomat 中有效，但在 jboss 的 .ear 中无效。
@JanezKuhar 我想确定我明白了，你是说要注释掉焊缝和 cxf 的导入，然后用 pom 中 javaee-api 的导入重新替换它吗？
@LautaroSausa 是的

标签： java eclipse maven jboss

【解决方案1】：

终于让它工作了。

正如@JanezKuhar 所说，我评论了 pom 中所有额外的库并添加了两个，现在看起来像这样：

            </plugin>
        </plugins>
    </build>
</project>

注释 servlet 部分并将 restEasy scan 设置为 true，在 web.xml 中：

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
    <display-name>Archetype Created Web Application</display-name>

    <context-param>
        <param-name>resteasy.scan</param-name>
        <param-value>true</param-value>
    </context-param>
    <context-param>
        <param-name>resteasy.scan.providers</param-name>
        <param-value>true</param-value>
    </context-param>
    <context-param>
        <param-name>resteasy.scan.resources</param-name>
        <param-value>true</param-value>
    </context-param>

    <listener>
        <listener-class>org.jboss.weld.environment.servlet.Listener</listener-class>
    </listener>

</web-app>

现在它可以工作了，我可以访问部署在 jboss 中的 REST 服务。

感谢提供的帮助。

【讨论】：

【解决方案2】：

你的 jboss-app.xml 在哪里？ maven会创建它吗？在 jboss-app.xml 您（或 maven）应该创建应用程序的上下文根。

jboss-app.xml：每个 EAR 应用程序都应该为类加载器指定一个唯一的字符串名称。它来自 JBoss 文档。 link
