springboot+feign+nacos+seata+docker整合踏坑实录

一、版本

springboot:2.7.2

feign:3.1.5

jdk:19

seata:1.5.2

nacos:V2.1.2

二、docker部署

1.配置文件实列

配置说明

下述配置为该当前最新镜像，seata的配置不需要区分成网上所说的registry.conf 、file等配置文件。

nacos和seata的配置文件可先启动容器之后从容器中拿出配置文件再做响应的修改。

docker-compose.yml配置文件：

2.问题记录

1.当用docker-compose启动该实列seata-server启动会失败，原因是因为depends_on配置的编排虽然等待了nacos容器的启动但是nacos实列还未完全启动成功，所以导致seata-server启动失败。

解决方案为重新再次启动一次seata-server

2.docker-compose.yml文件中个镜像启动配置一定配置好container_name。

3.seata-server的application.yml配置文件注册中心地址一定使用宿主机ip，不要使用docker配置的域名，会导致注册不上去。报**failed to req API:/nacos/v1/ns/instance after all servers([nacos_server:8848]) **错误！

三、springboot客户端配置

启动异常问题：

1.异常信息: org/springframework/boot/Bootstrapper，缺少spring-cloud-starter-bootstrap包，引入即可；

2.如果是springboot3.0.0版本讲读不到nacos的配置文件所以最好降下springboot的版本;

3.启动 Unable to make field protected java.lang.reflect.InvocationHandler java.lang.reflect.Proxy.h accessible: module java.base does not "opens java.lang.reflect" to unnamed module @3eb738bb Unable to make field protected java.lang.reflect.InvocationHandler java.lang.reflect.Proxy.h accessible: module java.base does not "opens java.lang.reflect" to unnamed module @3eb738bb，需要设置启动参数--add-opens java.base/java.lang.reflect=ALL-UNNAMED，如果是报错其它包就换其它包。
4.网络不通问题,宿主机无法ping通docker容器中的ip,报错异常信息为can not register RM,err:can not connect to services-server.。解决方案参考http://t.csdn.cn/taJtC
