项目 cxf 安装在 JBoss Fuse 上但仍然“没有找到服务”

【问题标题】：project cxf installed on JBoss Fuse but still "no services have been found"项目 cxf 安装在 JBoss Fuse 上但仍然“没有找到服务”
【发布时间】：2017-10-11 19:23:50
【问题描述】：

我正在尝试学习如何使用 cxf 和 JBoss Fuse 制作 REST 服务。在服务器上成功安装服务后，我尝试在http://localhost:8181/cxf 上查看已安装的 cxf 服务列表，得到“未找到服务”的表达式。有人知道为什么没有服务没有出现，我该如何显示？ 我用作测试的代码是本教程中的代码https://www.tutorialspoint.com/jboss_fuse/jboss_fuse_rest_web_services.htm，从 maven 项目 org.apache.cxf cxf-http-basic 开始

编辑 1：在遵循 Abolfazl 的有用重写指南后，我安装并再次启动了该服务。 这次做 osgi:list 我得到了

[ 320] [Active     ] [Failure     ] [       ] [   80] mvn:com.tuts.abhinav/rest-service/1.0-SNAPSHOT

在做 log:display 时我得到了

【问题讨论】：

  • 你在安装和启动捆绑包后检查控制台日志了吗？请在 jboss fuse 控制台中输入“list”命令并检查捆绑状态是否为“活动”。
  • 安装并运行捆绑包后，日志中没有错误，就像服务运行正常一样。当我检查 osgi:list 包的状态是活动的

【解决方案1】：

也许可以试试这个来自 Fuse 的 REST 示例？它使用 JBoss Fuse 6.3：

https://github.com/jboss-fuse/quickstarts/tree/master/cxf/rest

【讨论】：

  • 安装并启动您的示例后，我可以在localhost:8181/cxf 上看到您的服务，但我仍然不明白为什么我看不到我正在使用的另一个示例。
【解决方案2】：

以上样本需要做如下修正：

1-在代码最后一行的“Add Fuse Plugin Repositories”部分，“”必须替换为。

2-在代码第 6 行的“添加构建指令”部分中，“artifalctId”必须替换为“artifactId”。

创建和部署上述示例的正确步骤如下：

1-使用以下命令创建一个简单的 Maven 快速启动项目：

mvn archetype:generate -DgroupId=com.tuts.abhinav -DartifactId=rest-service -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

2-更改项目结构，直到您具有以下结构：

3-“UserService.java”类必须有以下内容：

package com.tuts;

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

@Path("/UserService_1")
public class UserService {
   @GET
   @Path("/get_data")
   @Produces(MediaType.APPLICATION_JSON)

   public String getUser() {
      String reponse = "This is standard response from REST";
      return reponse;
   }
}

4-“blueprint.xml”文件应该有以下内容：

<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:jaxrs="http://cxf.apache.org/blueprint/jaxrs"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0     http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd    http://cxf.apache.org/blueprint/jaxrs     http://cxf.apache.org/schemas/blueprint/jaxrs.xsd">
    <jaxrs:server address="/users" id="service">
        <jaxrs:serviceBeans>
            <ref component-id="userService"/>
        </jaxrs:serviceBeans>
    </jaxrs:server>
    <bean class="com.tuts.UserService" id="userService"/>
</blueprint>

5-“pom.xml”文件应该有以下内容：

<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/maven-v4_0_0.xsd">

6-您可以使用以下命令安装项目：

mvn install

7-最后，您可以使用以下命令在 karaf 中部署项目包：

osgi:install -s mvn:com.tuts.abhinav/rest-service/1.0-SNAPSHOT

之后你的服务必须在http://localhost:8181/cxf url:

【讨论】：

  • 感谢您的帮助，但是我在熔断器上安装服务仍然有些问题。安装并执行 osgi:list 后，我​​得到：[320] [Active] [Failure] [] [80] mvn:com.tuts.abhinav/rest-service/1.0-SNAPSHOT。控制它说的日志：2017-05-22 17:19:09,545 |错误 | l 控制台线程 | BlueprintContainerImpl | 23 - org.apache.aries.blueprint.core - 1.4.5 |无法启动捆绑包 null/0.0.0 的蓝图容器
  • 请执行“log:display”命令并在此处打印您的异常。
  • cmets里面空间不够，我去编辑帖子写在那里
  • 请确保您的 MANIFEST.MF 在第一行包含：“Manifest-Version: 1.0”，在第二行包含“Class-Path:”。
  • MANIFEST.MF 很好，两行都如你所说
