java - 带有 Docker : environment variable to override RabbitMQ host IP property in spring boot's application. 属性的 Spring Boot 不工作

Question

我正在开发 spring boot 应用程序，我必须在其中使用 RabbitMQ 作为消息代理。我没有在我的本地主机上使用 RabbitMQ，而是使用以下命令使用来自 docker hub 的 docker 图像

docker run -d --name rabbit-name-management -p 15672:15672 -p 5672:5672 -p 15671:15671 -p 5671:5671 -p 4369:4369 rabbitmq:3-management

因此它拉取镜像并作为 docker 容器成功运行。

现在在我的 spring boot 应用程序中，我使用 application.properties文件以便连接到 RabbitMQ看起来如下所示:

spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=*****
spring.rabbitmq.password=********

我的 spring boot docker 文件

FROM openjdk:8-jdk-alpine
VOLUME /tmp
COPY encryptionKey.jks encryptionKey.jks
COPY UnlimitedJCEPolicyJDK8/* /usr/lib/jvm/java-1.8-openjdk/jre/lib/security/
COPY target/ConfigServer-0.0.1-SNAPSHOT.jar ConfigServer.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","ConfigServer.jar"]

我使用命令 docker inspect <RABBITMQ_CONTAINER_ID>找出运行 RabbitMQ 的机器的 IP 地址。为了让它与 RabbitMQ 进行通信，我使用环境变量来使用运行 RabbitMQ 的容器的实际 IP 地址覆盖 localhost。 docker 命令如下所示

docker run -p 8012:8012 -e "spring.rabbitmq.host=http://172.17.0.3" config-server

但是这个命令失败了，它记录了如下错误

2020-08-20 06:10:31.077 ERROR 1 --- [           main] o.s.boot.SpringApplication               : Application run failed

我不知道这是什么 unquoted IPv6 address以及为什么它在这里提示它以及我应该在这里做什么来消除这个错误。

Answer 1

来自 amqpclie-Address source code :

   /**
     * Extracts hostname or IP address from a string containing a hostname, IP address,
     * hostname:port pair or IP address:port pair.
     * Note that IPv6 addresses must be quoted with square brackets, e.g. [2001:db8:85a3:8d3:1319:8a2e:370:7348].
     *
     * @param addressString the string to extract hostname from
     * @return the hostname or IP address
     */
    public static String parseHost(String addressString) {          
       //...
      int lastClosingSquareBracket = addressString.lastIndexOf("]");
         if (lastClosingSquareBracket == -1) {
                    String[] parts = addressString.split(":");
                    if (parts.length > 2) { // HERE OCCURS THE ISSUE
                        String msg = "Address " +
                                            addressString +
                                            " seems to contain an unquoted IPv6 address. Make sure you quote IPv6 addresses like so: [2001:db8:85a3:8d3:1319:8a2e:370:7348]";
                        LOGGER.error(msg);
                        throw new IllegalArgumentException(msg);
                    }                   
                return parts[0];
            }
       //...
    }

您应该删除 http 前缀(这将使您的地址被视为 ip v4 格式):

docker run -p 8012:8012 -e "spring.rabbitmq.host=172.17.0.3" config-server
