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#

下载soul-examples-tars

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.SoulTestTarsApplicationmain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：

com.qq.tars.server.config.ConfigurationException: error occurred on load server config    at com.qq.tars.server.config.ConfigurationManager.loadServerConfig(ConfigurationManager.java:113)    at com.qq.tars.server.config.ConfigurationManager.init(ConfigurationManager.java:57)    at com.qq.tars.server.core.Server.loadServerConfig(Server.java:90)    at com.qq.tars.server.core.Server.<init>(Server.java:42)    at com.qq.tars.server.core.Server.<clinit>(Server.java:38)    at com.qq.tars.spring.bean.PropertiesListener.onApplicationEvent(PropertiesListener.java:37)    at com.qq.tars.spring.bean.PropertiesListener.onApplicationEvent(PropertiesListener.java:31)    at org.springframework.context.event.SimpleApplicationEventMulticaster.doInvokeListener(SimpleApplicationEventMulticaster.java:172)    at org.springframework.context.event.SimpleApplicationEventMulticaster.invokeListener(SimpleApplicationEventMulticaster.java:165)    at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:139)    at org.springframework.context.event.SimpleApplicationEventMulticaster.multicastEvent(SimpleApplicationEventMulticaster.java:127)    at org.springframework.boot.context.event.EventPublishingRunListener.environmentPrepared(EventPublishingRunListener.java:76)    at org.springframework.boot.SpringApplicationRunListeners.environmentPrepared(SpringApplicationRunListeners.java:53)    at org.springframework.boot.SpringApplication.prepareEnvironment(SpringApplication.java:345)    at org.springframework.boot.SpringApplication.run(SpringApplication.java:308)    at org.springframework.boot.SpringApplication.run(SpringApplication.java:1226)    at org.springframework.boot.SpringApplication.run(SpringApplication.java:1215)    at org.dromara.soul.examples.tars.SoulTestTarsApplication.main(SoulTestTarsApplication.java:38)Caused by: java.lang.NullPointerException    at java.io.FileInputStream.<init>(FileInputStream.java:130)    at java.io.FileInputStream.<init>(FileInputStream.java:93)    at com.qq.tars.common.util.Config.parseFile(Config.java:211)    at com.qq.tars.server.config.ConfigurationManager.loadServerConfig(ConfigurationManager.java:63)    ... 17 moreThe exception occurred at load server config

成功启动会有如下日志：

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
