macos – 使用Intellij IDEA重新加载远程Spring引导应用程序的例外

我正在尝试使用spring devtools,docker和IntelliJ设置远程spring-boot环境.一切都从article开始.不幸的是它随机失败,有例外.配置下方:

Dockerfile

FROM        java:8

EXPOSE      8888

WORKDIR     /app

ADD         build.gradle    /app/build.gradle
ADD         gradlew         /app/gradlew
ADD         gradle          /app/gradle

ADD         src             /app/src

RUN         ["chmod", "+x", "/app/gradlew"]

泊坞窗,compose.yml

backend:
  build: .
  env_file: environment
  ports:
    - "8888:8888"
  volumes:
    - ./.gradle-docker:/root/.gradle
  command: "/app/gradlew clean bootRun"
  links:
    - db

db:
  image:  postgres:9.5.3
  env_file: environment
  ports:
    - "5454:5432"

整个应用程序从命令行启动:docker-compose build和docker-compose up命令.

在IntelliJ中,我准备了以下java应用程序配置:
configuration

其中docker:8888是spring应用程序使用的docker-machine和port的IP.运行配置后,输出如下:

在docker和IntelliJ中:

2016-07-06 12:49:29.141  INFO 17731 --- [   File Watcher] o.s.b.d.r.c.ClassPathChangeUploader      : Uploaded 1 class resource

日志我看到上下文被重新加载.可能是什么问题?

最佳答案
Spring启动的DevTools中有一个bug,这意味着如果您在上次更改触发的重启过程中对应用程序进行了更改,则上载更改的尝试将失败.我想我们可能需要更新DevTools来重试上传尝试.

与此同时,唯一的“解决方案”是每当您看到由于java.net.ConnectException导致的失败时停止并重新启动RemoteSpringApplication:连接被拒绝.
