今天來學習 Sofa 的演示。

調試了一晚上，啥也沒調通。Ծ‸Ծ

分割線

梳理了昨晚調試的思路。今天重新來。

1. 清空頁面關於dubbo與sofa的配置。
2. 按順序啓動 admin->application->dubbo->sofa

這時sofa的啓動頁面報錯如下：

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} 

這表示sofa接口沒有註冊到項目中。

這時查看頁面，當前接口數據確實沒展示：

爲了一探究竟，我們重啓啓動sofa。

根根打印信息，我們在註冊位置打上斷點查看，得到debug結果如圖所示：

哦豁，系統 is busy！！！

 

爲啥busy了？

原來系統有個設置：

 @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時，代碼沒走這裏。o(╥﹏╥)o
