1. Provide parents and dependencies;
2. Use dependencies manage 3rdparties, and do not add version in sub modules.

1.users can add config to make header pass-through
by config : servicecomb.router.header
2.header spi ext need rewrite

client maintain a urls list , it will be refactory in the furture.

problem need to be resolve :

1. WARN log when invoke [string] type
2. ERROR log when invoke [pojo] use resttemplete

as saying in https://docs.spring.io/spring-boot/docs/current/reference/html/spring-boot-features.html#boot-features-developing-auto-configuration

You should make sure to provide a proper namespace for your starter. Do not start your module names with spring-boot, even if you use a different Maven groupId. 

and azure examples

<dependency>
<groupId>com.huaweicloud</groupId>
<artifactId>spring-cloud-huawei-dependencies</artifactId>
<version>1.2.0</version>
<type>pom</type>
<scope>import</scope>
</dependency>
在当前这个版本中，指定了
<spring-cloud.version>2.1.2.RELEASE</spring-cloud.version>
<spring-boot.version>2.1.6.RELEASE</spring-boot.version>
为什么还要指定<spring.version>5.2.3.RELEASE</spring.version>，spring的版本本身对springmvc就是有版本依赖管理的现在这样指定版本是有冲突的spring-boot的版本过低导致spring的api不兼容，我们发布前不测吗？基本的应用启动都起不来。

Currently is

org.springframework.cloud.huawei.config

and

org.springframework.cloud.dtm.consumer.feign

These are not very good. Change to the following

com.huaweicloud.config

and

com.huaweicloud.dtm

No additional configuration is required when building applications using Huawei Cloud.

there are missing depndencies like:

<dependency>
  <groupId>com.huawei.paas.dtm</groupId>
  <artifactId>dtm-client</artifactId>
</dependency>

gateway will invoke com.huaweicloud.servicecomb.discovery.discovery.ServiceCombDiscoveryClient#getServices
get all service include which status are not UP.
that will cause a error log when invoke getInstances() following:
2020-01-06 10:24:35.968 ERROR 10112 --- [ main] c.h.c.ServiceCombPropertySourceLocator : read response failed. status=401;mesage=Unauthorized

Some time we need encrpt config and decrpt in sdk.

同样使用例子中的spring-cloud-starter-huawei-servicecomb-discovery进行服务注册

测试可以使用服务id进行路由导航

gateway使用spring-cloud-starter-huawei-servicecomb-discovery,

服务提供者

org.apache.servicecomb
spring-boot-starter-provider
1.1.0

进行注册, 可以使用uri的方式进行路由,但是使用微服务id的方式进行路由报如下错误
java.lang.IllegalStateException: Invalid host: lb://workspace_service

When microservice have more than one schemas and using servicecomb-service-center 1.3.0, only one schema registration is successful.

some package name in the unit test is
org.springcloudframework.cloud
we need to change it to
com.huaweicloud

if exist mutiple instances with different version , we can only get the latest version instance .
cause:
org.springframework.cloud.servicecomb.discovery.client.model.ServiceRegistryConfig#DEFAULT_CALL_VERSION
it's a fix value

Now is Greenwich.SR5 and not related to this current development status.

• upgrade to Hoxton SR4
• reoganize the dependency management

spring.application.name and spring.cloud.servicecomb.discovery.serviceName have the same meaning.

version: master
env: macos10.13 + jdk 1.8

sch看上去已经有很多组件了，但是readme没有同步更新

Why having this feature:

• Eanbles servicecomb RPC consumer to invoke spring cloud REST service

Hi. The configurations for feature switch are irregular in spring-cloud-huawei.
For example, the config item to enable the credentials is spring.cloud.servicecomb.credentials.enable, while the config item to enable the service registry is spring.cloud.servicecomb.discovery.enabled. Conventionally, such kind of config items are usually suffixed by enabled.
And I find that the config key spring.cloud.servicecomb.discovery.enabled are referred in different places in literal form. Maybe it's better to define a const for it.
Any ideas? : )

在properties中使用的是enable而在@ConditionalOnProperty中使用的是enabled，名称为什么不统一

@Component @ConfigurationProperties("spring.cloud.servicecomb.config") public class ServiceCombConfigProperties { private boolean enable = true;

@Configuration @ConditionalOnServiceCombEnabled @ConditionalOnProperty( name = {"spring.cloud.servicecomb.config.enabled"}, matchIfMissing = true ) public class ServiceCombConfigAutoConfiguration

@Configuration @ConditionalOnProperty( name = {"spring.cloud.servicecomb.config.enabled"}, matchIfMissing = true ) public class ServiceCombConfigBootstrapConfiguration

可以要求开发者写注解，service center支持契约的管理，期望服务启动后能够自动注册契约到service center中

• set project to 1.3.3-Hoxton-SNAPSHOT

@RestController
@RequestMapping(path = "/", produces = MediaType.APPLICATION_JSON_VALUE)
public class UserEndpoint {
  @Autowired
  private UserService userService;

  @PostMapping(path = "/v1/user/login", produces = MediaType.APPLICATION_JSON_VALUE)
  @ResponseBody
  public SessionInfo login(@RequestParam(name = "userName") String userName,
      @RequestParam(name = "password") String password) {
    return userService.login(userName, password);
  }

got

This is not correct

门禁执行时长大幅降低

check style

coveralls

以及安全编程检查

Now only print register failed for servicecomb id and schema id, do not print reason.

Suggestions: print reason content in response and make user's find the cause easier.

Now there are no integration tests, we can add demo dicovery to integration tests.

[dtm module] and [router modele] only support feign client and resttemplet client for now.
We need support spring webflux in the future.

Servicestage constraints docker file path to have xx words, and lastest version fixed this issue. The docker file and scripts with short path can be deleted.

ServiceComb has application name , spring cloud not have this.
It is for aggregation services

com/huaweicloud/servicecomb/discovery/registry/ServiceCombServiceRegistry.java
这个java类中涉及到服务注册的环境，里头的loopRegister反复注册的方法采用了while(true)的方式，微服务启动过程如果没有配置注册中心地址或者没有启动注册中心的话，会一直在这里做循环，主函数main中的SpringApplication.run后面的执行语句如打印服务启动成功日志会因此无法执行。
是否可以考虑优化成异步注册的方式，异步处理重试注册的场景？

config demo里给的config.serverAddr端口号和提供的本地配置中心对不上，需要改成30113
