java.lang.NoSuchMethodError: org.springframework.boot.builder.SpringApplicationBuilder
原因： Springboot 与 Springcloud 版本冲突问题 解决： Springboot 与 Springcloud 版本对应关系可以去spring官网查看
com.jcraft.jsch.JSchException: Auth fail
Cannot clone or checkout repository
原因： 无权限操作，检查用户名和密码 解决： 输入正确的用户名和密码，只有 uri 采用 https 的方式才需要配置用户名和密码，如下图所示： 关于 ssh 的配置参数官网： Git SSH configuration using properties
关于 alibaba nacos 注册成功无法查看服务问题、nacos 无法启动问题
原因： Spring Cloud 、Spring Boot 和 Spring Cloud Alibaba 版本不一致导致 **解决： ** 参考官网
i.s.c.r.netty.NettyClientChannelManager : no available service ‘null’ found, please make sure registry config correct
保证 seata.tx-service-group 值与 seata.service.vgroup-mapping 中的 key 一致，见如下截图
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.
解决：
1. 查看nacos配置列表，seata配置是否已经导入成功
2. 查看nacos服务列表，serverAddr是否已经注册成功
3. 检查client端的registry.conf里面的namespace，registry.nacos.namespace和config.nacos.namespace填入nacos的命名空间ID，默认""，server端和client端对应，namespace 为public是nacos的一个保留控件，如果您需要创建自己的namespace，最好不要和public重名，以一个实际业务场景有具体语义的名字来命名
4. nacos上服务列表，serverAddr地址对应ip地址应为seata启动指定ip地址，如：sh seata-server.sh -p 8091 -h 122.51.204.197 -m file
启动时一定要指定启动ip，另外不要指定127.0.0.1
6. 查看seata/conf/nacos-config.txt 事务分组service.vgroupMapping.trade_group=default配置与项目分组配置名称是否一致
7. telnet ip 端口 查看端口是都开放，以及防火墙状态

解决办法： 在 bean 中 set 前加入下面代码或在启动类main方法最前加入
System.setProperty("es.set.netty.runtime.available.processors", "false");

原因： restTemplete 不支持 gzip 解压
解决办法：
方案一：检查请求头中是否存在 Accept-Encoding : gzip ，如果有，可去掉
方案二：检查 Nginx 是否配置了 gzip 压缩 json ，如果有，可去掉
方案三：
HttpComponentsClientHttpRequestFactory clientHttpRequestFactory = new HttpComponentsClientHttpRequestFactory();
RestTemplate restTemplate = new RestTemplate(clientHttpRequestFactory);
