#### 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 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][Link 1]![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI0NTk4NjAx_size_16_color_FFFFFF_t_70 2]

#### 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: 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

#### java.lang.IllegalStateException: availableProcessors is already set to \[8\], rejecting \[8\] ####

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);
