一、前言

本文承接上一节：猪齿鱼_01_环境搭建(一)_微服务支撑组件部署

前面两节，我们已经完成了猪齿鱼微服务支撑组件的部署；

这一节，我们来看下如何在前面部署好的微服务支撑组件的基础上，进行我们的业务服务的开发。

二、整合业务服务

这里我们将创建一个简单的Demo工程，然后将此工程整合进来。

1.创建工程

1.1 创建SpringBoot工程

创建一个SpringBoot工程即可，工程的GAV如下

groupId：hec-panda-cloud
artifactId：panda-cloud-service
version：1.0-SNAPSHOT

1.2 修改pom.xml

工程的pom.xml文件内容如下：

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

    <groupId>hec-panda-cloud</groupId>
    <artifactId>panda-cloud-service</artifactId>
    <version>1.0-SNAPSHOT</version>
    <modelVersion>4.0.0</modelVersion>

1.3 新建 PandaSystemExtraDataManager.java

此文件是用来将当前工程的接口信息注册到Swagger中。
文件内容如下：

/*
 *
 *  项目名称：choerodon-framework-parent
 *  Copyright @ 2018  Shanghai Hand Co. Ltd.
 *  All right reserved.
 *
 *
 */

package io.choerodon.demo;

import io.choerodon.core.swagger.ChoerodonRouteData;
import io.choerodon.swagger.annotation.ChoerodonExtraData;
import io.choerodon.swagger.custom.extra.ExtraData;
import io.choerodon.swagger.custom.extra.ExtraDataManager;

/** HcbmTemplateExtraDataManager
 *
 * @author yinbo.shi@hand-china.com
 * @date 2018/06/14
 */
@ChoerodonExtraData
public class PandaSystemExtraDataManager implements ExtraDataManager {

    @Override
    public ExtraData getData() {
        ChoerodonRouteData choerodonRouteData = new ChoerodonRouteData();

        choerodonRouteData.setName("panda-system");
        choerodonRouteData.setPath("/panda/system/**");
        choerodonRouteData.setServiceId("panda-system");
        extraData.put(ExtraData.ZUUL_ROUTE_DATA, choerodonRouteData);
        return extraData;
    }
}

2.指定注册中心地址

eureka
  client:
    serviceUrl:
      defaultZone: http://localhost:8000/eureka/
