java.lang.NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder

原因： Springboot 與 Springcloud 版本沖突問題

解決： Springboot 與 Springcloud 版本對應關系可以去spring官網檢視

com.jcraft.jsch.JSchException: Auth fail

Cannot clone or checkout repository

原因：無權限操作，檢查使用者名和密碼

解決：輸入正确的使用者名和密碼，隻有

uri

采用

https

的方式才需要配置使用者名和密碼，如下圖所示：

保證 seata.tx-service-group 值與 seata.service.vgroup-mapping 中的 key 一緻，見如下截圖

【持續更新】SpringCloud 學習之異常解決辦法總結

io.seata.common.exception.FrameworkException: can not register RM,err:can not connect to services-server

io.seata.common.exception.FrameworkException: connect failed, can not connect to services-server.

解決：

1. 檢視nacos配置清單，seata配置是否已經導入成功
2. 檢視nacos服務清單，serverAddr是否已經注冊成功
3. 檢查client端的registry.conf裡面的namespace，registry.nacos.namespace和config.nacos.namespace填入nacos的命名空間ID，預設""，server端和client端對應，namespace 為public是nacos的一個保留控件，如果您需要建立自己的namespace，最好不要和public重名，以一個實際業務場景有具體語義的名字來命名
4. nacos上服務清單，serverAddr位址對應ip位址應為seata啟動指定ip位址，如：sh seata-server.sh -p 8091 -h 122.51.204.197 -m file
啟動時一定要指定啟動ip，另外不要指定127.0.0.1
6. 檢視seata/conf/nacos-config.txt 事務分組service.vgroupMapping.trade_group=default配置與項目分組配置名稱是否一緻
7. telnet ip 端口 檢視端口是都開放，以及防火牆狀态

解決辦法：

在 bean 中 set 前加入下面代碼或在啟動類main方法最前加入

System.setProperty("es.set.netty.runtime.available.processors", "false");

原因： restTemplete 不支援 gzip 解壓

解決辦法：

方案一：檢查請求頭中是否存在 Accept-Encoding : gzip ，如果有，可去掉
方案二：檢查 Nginx 是否配置了 gzip 壓縮 json ，如果有，可去掉
方案三：

HttpComponentsClientHttpRequestFactory clientHttpRequestFactory = new HttpComponentsClientHttpRequestFactory();
RestTemplate restTemplate = new RestTemplate(clientHttpRequestFactory);
