Soul网关第四天- 演示Sofa RPC应用示例

soul源码地址：https://github.com/dromara/soul

今天来学习 Sofa 的演示。

调试了一晚上，啥也没调通。Ծ‸Ծ

分割线 

梳理了昨晚调试的思路。今天重新来。

清空页面关于dubbo与sofa的配置。 按顺序启动 admin->application->dubbo->sofa

这时sofa的启动页面报错如下：

2021-01-19 22:05:58.407 INFO 2679 --- [ main] trationDelegate$BeanPostProcessorChecker : Bean 'restTemplateBuilder' of type [org.springframework.boot.web.client.RestTemplateBuilder] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying) 2021-01-19 22:05:58.523 ERROR 2679 --- [pool-1-thread-1] o.d.s.client.common.utils.RegisterUtils : sofa client register error: {"appName":"sofa","contextPath":"/sofa","path":"/sofa/insert","pathDesc":"Insert a row of data","rpcType":"sofa","serviceName":"org.dromara.soul.examples.dubbo.api.service.DubboTestService","methodName":"insert","ruleName":"/sofa/insert","parameterTypes":"org.dromara.soul.examples.dubbo.api.entity.DubboTest","rpcExt":"{\"loadbalance\":\"hash\",\"retries\":3,\"timeout\":-1}","enabled":true} 2021-01-19 22:05:58.535 ERROR 2679 --- [pool-1-thread-1] o.d.s.client.common.utils.RegisterUtils : sofa client register error: {"appName":"sofa","contextPath":"/sofa","path":"/sofa/findById","pathDesc":"Find by Id","rpcType":"sofa","serviceName":"org.dromara.soul.examples.dubbo.api.service.DubboTestService","methodName":"findById","ruleName":"/sofa/findById","parameterTypes":"java.lang.String","rpcExt":"{\"loadbalance\":\"hash\",\"retries\":3,\"timeout\":-1}","enabled":true} 2021-01-19 22:05:58.545 ERROR 2679 --- [pool-1-thread-1] o.d.s.client.common.utils.RegisterUtils : sofa client register error: {"appName":"sofa","contextPath":"/sofa","path":"/sofa/findAll","pathDesc":"Get all data","rpcType":"sofa","serviceName":"org.dromara.soul.examples.dubbo.api.service.DubboTestService","methodName":"findAll","ruleName":"/sofa/findAll","parameterTypes":"","rpcExt":"{\"loadbalance\":\"hash\",\"retries\":3,\"timeout\":-1}","enabled":true}

这表示sofa接口没有注册到项目中。

这时查看页面，当前接口数据确实没展示：

为了一探究竟，我们重启启动sofa。

根根打印信息，我们在注册位置打上断点查看，得到debug结果如图所示：

哦豁，系统 is busy！！！

 

为啥busy了？

原来系统有个设置：

@ExceptionHandler(Exception.class) @ResponseBody protected SoulAdminResult serverExceptionHandler(final Exception exception) { log.error(exception.getMessage(), exception); String message; if (exception instanceof SoulException) { SoulException soulException = (SoulException) exception; message = soulException.getMessage(); } else { message = "The system is busy, please try again later"; } return SoulAdminResult.error(message); }

但我debug时，代码没走这里。o(╥﹏╥)o
