我的本地（没有 docker）很好，工作没有任何问题。本地设置工作正常。Server-Jar：运行于 8081Client-War：运行在 8000，可以毫无问题地连接到 Server Jar。DOCKER 设置docker-compose.yml服务器employee: image: openjdk:jdk-alpine container_name: "employee" ports: - 9081:8080 - 9991:9990 - 65193:65193 volumes: - ./Employee/target/Employee-1.0-SNAPSHOT-jar-with-dependencies.jar:/deployments/Employee-1.0-SNAPSHOT-jar-with-dependencies.jar environment: - JAVA_OPTS=-agentlib:jdwp=transport=dt_socket,address=0.0.0.0:65193,suspend=n,server=y -Djava.net.preferIPv4Stack=true - GRPC_PORT=8080 command: java -jar /deployments/Employee-1.0-SNAPSHOT-jar-with-dependencies.jarclient: image: jboss/wildfly container_name: "client" ports: - 9080:8080 - 9990:9990 - 65193:65193 volumes: - ./Service/target/Service.war:/opt/jboss/wildfly/standalone/deployments/Service.war environment: - JAVA_OPTS=-agentlib:jdwp=transport=dt_socket,address=0.0.0.0:65193,suspend=n,server=y -Djava.net.preferIPv4Stack=true - EMPLOYEE_HOST=localhost:9081 command: > bash -c "/opt/jboss/wildfly/bin/add-user.sh admin Admin#007 --silent && /opt/jboss/wildfly/bin/standalone.sh -b 0.0.0.0 -bmanagement 0.0.0.0"links: - employeedepends_on: - employee员工服务器代码Server server = ServerBuilder.forPort(Integer.parseInt(env.get("GRPC_PORT"))) .addService(new Employee()) .build();try { server.start(); System.out.println("Server listening at: " + env.get("GRPC_PORT")); server.awaitTermination();} catch (IOException | InterruptedException e) { e.printStackTrace();}客户端连接代码。ManagedChannel channel = ManagedChannelBuilder.forTarget(env.get("EMPLOYEE_HOST")).usePlaintext().build();EmployeeServiceGrpc.EmployeeServiceBlockingStub employee = EmployeeServiceGrpc.newBlockingStub(channel);当我进行 gRPC 调用时抛出错误。您认为 docker 设置正确吗？如果那么我可以在其他地方寻找问题

看到这个人为的例子：
version: "3"
services:
server:
image: nginx:1.17.3
restart: always
container_name: nginx
expose:
- "80"
ports:
- 8888:80
client:
image: busybox:1.31.0
restart: always
depends_on:
- server
container_name: busybox
command:
- ash
- -c
- |
while true;
do
wget --spider http://server:80 2>&1
sleep 5s;
done;
client通过端口访问 Nginx 容器80，但它用作server主机地址以解析到适当的 (Nginx) 容器。
如果您要替换server为localhostin client，则客户端会尝试wget对自己执行命令，但会失败。
因为server发布8888到主机，当 Docker Compose 启动时，从主机（！），你可以wget http://localhost:8888并且这将起作用（200）。
