Tars快速开始
本文档将演示如何快速使用Tars接入Soul网关。您可以直接在工程下找到本文档的示例代码。
环境准备
请参考配置网关环境并启动soul-admin
和soul-bootstrap
。
注:soul-bootstrap
需要引入tars依赖
<dependency>
<groupId>org.dromara</groupId>
<artifactId>soul-spring-boot-starter-plugin-tars</artifactId>
<version>${project.version}</version>
</dependency>
<dependency>
<groupId>com.tencent.tars</groupId>
<artifactId>tars-client</artifactId>
<version>1.7.2</version>
</dependency>
运行soul-examples-tars项目
修改application.yml
中的host
为你本地ip
修改配置src/main/resources/SoulExampleServer.SoulExampleApp.config.conf
:
- 建议弄清楚 config 的主要配置项含义, 参考开发指南
- config 中的 ip 要注意提供成本机的
- local=…, 表示开放的本机给 tarsnode 连接的端口, 如果没有 tarsnode, 可以掉这项配置
locator
: registry服务的地址,必须是有ip port的,如果不需要registry来定位服务,则不需要配置;node=tars.tarsnode.ServerObj@xxxx
,表示连接的 tarsnode 的地址,如果本地没有 tarsnode, 这项配置可以去掉
更多config配置说明请参考Tars官方文档
运行org.dromara.soul.examples.tars.SoulTestTarsApplication
main方法启动项目。
注: 服务启动时需要在启动命令中指定配置文件地址 -Dconfig=xxx/SoulExampleServer.SoulExampleApp.config.conf
如果不加-Dconfig
参数配置会可能会如下抛异常:

tars 插件设置
- 在
soul-admin
插件管理中,把tars
插件设置为开启。
测试
soul-examples-tars
项目成功启动之后会自动把加 @SoulTarsClient
注解的接口方法注册到网关。
打开插件管理->tars可以看到插件规则配置列表
下面使用postman模拟http的方式来请求你的tars服务
