servicecomb-samples's Introduction

ServiceComb samples

This project is samples for java-chassis 3.x.x. You can switch to other branches to see different samples.

basic

A sample shows a provider, a consumer and a gateway using java chassis.

porter_lightweight

A sample shows an application with basic login, download file, delete file functions. Read this document for details.

porter_springboot

A sample shows an application with basic login, download file, delete file functions. Read this document for details.

java-chassis-samples

Featured samples for java-chassis modules. Each module contains 10 minutes guides.

java-chassis-integration-tests

java-chassis integration tests。

Precondition

Before running the samples，install service center and kie. Or download Lightweight Cloud Service Engine which integrates both service center and kie for ease of use.

使用ServiceComb开发微服务的示例项目

这个项目使用java-chassis 2.0.x版本。可以切换分支，查看其他版本的例子。

basic

该项目展示了Java Chassis开发的一个provider，一个consumer和一个网关服务。

porter_lightweight

该项目演示了一个包括网关、文件下载、认证鉴权等功能的简单应用系统，同时演示了ServiceComb推荐的先写接口声明，再写业务代码的软件工程实践。可以阅读文章了解项目的细节。这个例子的运行环境采用vert.x作为HTTP服务器，即 REST over Vert.x transport。

porter_springboot

该项目演示了一个包括网关、文件下载、认证鉴权等功能的简单应用系统，同时演示了ServiceComb推荐的先写接口声明，再写业务代码的软件工程实践。可以阅读文章了解项目的细节。这个例子的运行环境采用Spring Boot及其Embeded Tomcat，即 REST over Servlet。

java-chassis-samples

java-chassis 各个模块功能的例子。每个子项目包含了10分钟可以学习完成的简单示例。

java-chassis-integration-tests

java-chassis 的集成测试用例。

前提条件

运行这些例子之前，需要先安装注册中心和配置中心。华为云提供一个出色的本地轻量化微服务引擎 ,可以直接下载安装使用。

servicecomb-samples's Issues

porter document link is broken

org.apache.servicecomb:java-chassis-bom:${project.version}

我不知道我这样引用是否正确，我在我的项目中使用了

org.apache.servicecomb
java-chassis-parent
2.1.5

但是无法启动，因为我必须在我的项目中规定2.1.5
否则会提示
[ERROR] The build could not read 1 project -> [Help 1]

于是我找到了在java-chassis-dependencies-2.1.5.pom中876行有如下内容

org.apache.servicecomb
java-chassis-bom
${project.version}
pom
import

我想知道是不是我使用的方式错误，这样导致我无法规定自己项目的版本号

root cannot start with '/'

servicecomb-samples/java-chassis-samples/bmi/webapp项目启动报java.lang.IllegalArgumentException: root cannot start with '/'异常

这个命令是不是错了

我按照porter_lightweight和springboot中readme的操作启动服务，webroot也设置了，并且把ui文件夹放在了${gateway.webroot}下，但访问/ui/login.html出错:Request has already been read

java编码形式对接cse配置中心

你好，目前我需要java以编码形式获取配置中心的内容，以及当配置发生变更后主动推送给我的java某个线程，请问我需要怎么做？类似对接nacos配置中心一样（ConfigService cs=NacosFactory.createConfigService(properties);之后能够使用ConfigService的实例对象获取nacos上的配置）。

指标服务的端口是多少？在哪查看？

已经设置了rest接口为8081，发现无法查看metrics数据：
配置：

调用：

localhost 拒绝了我们的连接请求

basic的logger配置文件不正确，需要使用logback

在CSE中使用Handler进行拦截时，抛出的异常如何正常回显至调用方

在CSE中使用Handler进行拦截时，Handler抛出了相应的自定义异常，CSE会对异常进行封装，如何让CSE不进行原异常的封装而是原异常抛出

org.apache.servicecomb.samples.bmi.CalculatorRestEndpoint 类注释中内容错误

类注释如下：

/**
 * {@link CalculatorRestEndpoint} provides the rest implementation of {@link CalculatorEndpoint}.
 * The rest endpoint is accessed by /bmi?height={value}&width={value} with HTTP GET.
 */

其中，/bmi?height={value}&width={value} 中的 width 字段应该是 weight 。

BMI例子没有办法正常启动

通过本地service center 2.0启动后，运行BMI例子，没有办法正常访问前端界面，前段提示404，后台提示：[ntloop-thread-7] o.a.s.c.rest.locator.OperationLocator : locate path failed, status:Not Found, http method:GET, path:/, microserviceName:gateway

专业版引擎软件包部署应用失败

专业版部署提示信息：auth token valid fail: AK/SK/project not present
ps：同样环境下，使用专业版部署天气预报应用是正常的。

Feature: Adding contributors section to the README.md file.

There is no Contributors section in readme file .
As we know Contributions are what make the open-source community such an amazing place to learn, inspire, and create.
The Contributors section in a README.md file is important as it acknowledges and gives credit to those who have contributed to a project, fosters community and collaboration, adds transparency and accountability, and helps document the project's history for current and future maintainers. It also serves as a form of recognition, motivating contributors to continue their efforts.
