Payara Docker 数据源连接问题

Question

我开发了一个简单的 JAKARTAEE 网络应用程序并使用 netbeans 将其部署到 payara。我已经通过 docker 设置了一个 mysql 数据库并且它工作正常。现在我正在尝试使用 docker-compose.yml 文件来设置 mysql 和 payara 服务器。问题是，当我尝试将我的 payara-server 容器化时，我似乎无法访问数据库...

我的 docker-compose.yml 看起来如下：

version: '3'

services:
  docker-mysql:
    container_name: docker-mysql
    restart: always
    image: mysql:8
    environment:
      MYSQL_DATABASE: helloworld
      MYSQL_ROOT_PASSWORD: snoopy
      MYSQL_ROOT_HOST: '%'
      MYSQL_USER: snoopy
      MYSQL_PASSWORD: snoopy
    expose:
      - "3306"
    ports:
      - "3306:3306"
    networks:
      - backend

  helloworld-javaee-app:
    container_name: helloworld-javaee-app
    restart: on-failure
    build: ./
    expose:
      - "8080"
      - "4848"
    ports:
      - "8080:8080"
      - "4848:4848"
    environment:
      DATASOURCE_URL: jdbc:mysql://docker-mysql:3306
      DATASOURCE_USERNAME: root
      DATASOURCE_PASSWORD: snoopy
      DATASOURCE_DATABASE: helloworld
    depends_on:
      - docker-mysql
    networks:
      - backend
networks:
    backend:

我的 Dockerfile 如下所示：

#
# Build stage
#
FROM maven:3.6.0-jdk-11-slim AS build
WORKDIR /
COPY . /home/app
RUN mvn -f /home/app/pom.xml clean package

#
# Package stage
#
FROM payara/server-full
COPY --from=build /home/app/target/*.war $DEPLOY_DIR

</resources>

有人面临类似的情况吗？我似乎无法找到为什么 payara 无法达到 docker-mysql...

错误：

| Caused by: com.mysql.cj.exceptions.CJCommunicationsException: Communications link failure
 The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

将 glassfish-resources.xml 更改为 payara-resources.xml 并将文件内容更改为：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE resources PUBLIC "-//Payara.fish//DTD Payara Server 4 Resource Definitions//EN" "https://raw.githubusercontent.com/payara/Payara-Server-Documentation/master/schemas/payara-resources_1_6.dtd">
<resources>
    <jdbc-resource enabled="true" 
                   pool-name="MySQLPool" 
                   jndi-name="java:app/jdbc/hibernate"/>
    <jdbc-connection-pool name="MySQLPool" 
                          res-type="javax.sql.DataSource" 
                          datasource-classname="com.mysql.cj.jdbc.MysqlDataSource">
      <property name="URL" value="jdbc:mysql://docker-mysql:3306/helloworld"/>
      <property name="UseSSL" value="false"></property>
      <property name="User" value="snoopy"></property>
      <property name="Password" value="snoopy"></property>
      <property name="AllowPublicKeyRetrieval" value="true"></property>
    </jdbc-connection-pool>
</resources>

它奏效了...将它留在这里供遇到相同问题的任何人使用。我认为问题是 root 用户，尽管我将 MYSQL_ROOT_HOST 指定为 %
