Question

我试图使用JBOSS AS7制作一些REST服务但是当我尝试访问它们时，日志显示为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，以便在JBOSS中进行部署。

我使用CXF和CDI来提供服务 JBOSS的EasyRest版本为3.0.5。

这是WAR项目的pom.xml：

这是EAR包的pom.xml，它引用了一个JAR，因为在一个教程中，我发现使用maven制作EAR，它说要使用它，但没有任何东西：

<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">

此类名为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"

       http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
       bean-discovery-mode="all">
</beans>

这是web.xml：

<!DOCTYPE web-app PUBLIC

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

</web-app>

当我尝试在tomcat中运行它完美时，但在JBOSS中只获得404 我认为这可能是图书馆的问题，但不知道特别是什么问题。

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，那就很抱歉。

祝你有个愉快的一天。

但现在它给了我以下错误：

引起：java.lang.ClassNotFoundException：org.apache.cxf.cdi.CXFCdiServlet来自[Module＆＃34; deployment.projectEar.ear.projectWARModule-0.0.1-SNAPSHOT.war：main＆＃34;来自服务模块加载器]

最终完成这项工作。

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

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

    </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，我可以访问jboss中部署的REST服务。

感谢您提供的帮助。

Answer 2

你的jboss-app.xml在哪里？ maven是否创造了它？在jboss-app.xml中，您（或maven）应该创建应用程序的上下文根。

jboss-app.xml ：每个EAR应用程序都应为类加载器指定唯一的字符串名称。它来自JBoss doc。 link

REST服务确实在jboss AS 7中加载
