1、es7.10.2报错：The number of object passed must be even but was [1]

解决：将.doc( XContentType.JSON,map)改为.doc(JSONObject.toJSONString(map), XContentType.JSON)

2、nacos2.x报错：NacosException: Client not connected,current status:STARTING

解决：docker启动时增加grpc端口，以下参考https://github.com/alibaba/nacos/issues/6154

docker run -d --name nacos-server -p 8848:8848 -p 9848:9848 \
--privileged=true \
--restart=always \
-e JVM_XMS=256m \
-e JVM_XMX=256m \
-e MODE=standalone \
-e PREFER_HOST_MODE=hostname \
-v /devtools/nacos/logs:/data/nacos/logs \
-v /devtools/nacos/conf/application.properties:/data/nacos/conf/application.properties \
nacos/nacos-server:2.0.3

云端口两个也要打开
