小编Chi*_*ani的帖子

我正在使用Eclipse Juno 4.2,Java 1.7和Tomcat 7.但是在我的系统中,当我创建servlet时,web.xml文件不会自动创建,而是另一个系统会自动创建web.xml文件.我完全糊涂了,有什么配置吗？

我还要web.xml在创建动态项目时添加文件.

这是我的示例docker-compose.yml文件.

version: '2'
config-server:
  image: ccc/config-server
  restart: always
registration-server:
  image: ccc/registration-server
  restart: always
  ports:
    - 1111:1111

当我使用时,docker-compose up -d我得到一个错误:

"ERROR: The Compose file './docker-compose.yml' is invalid because:
Additional properties are not allowed ('registration-server', 'config-server' were unexpected)

You might be seeing this error because you're using the wrong Compose file version. Either specify a version of "2" (or "2.0") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at …

这是我的代码管道部署阶段：

        {"type":"PLAINTEXT","name":"GIT_COMMIT_ID", "value":"#{GitlabCustomSource.commit_id}"}]'
      RunOrder: 2

我得到的确切错误是

ActionConfiguration 映射值必须满足约束：[成员的长度必须小于或等于 1000，成员的长度必须大于或等于 1]（服务：AWSCodePipeline；状态代码：400；错误代码：ValidationException；请求 ID：c6fe0776- 5582-4d0d-a95d-64f7bf34f87e；代理：空）

我该如何解决这个问题？有没有其他方法可以将参数值传递给cloudformation模板？

从导出数据时出错mysql 5.5.29(winx-64).我在用mysql workbench -gpl-5.2.45(win 32).

错误消息是:

**WARNING**

Error checking mysqldump version
Error retrieving version from mysqldump.exe:

我是MySQL新手.

如果我使用我的弹簧工具套件运行,那么它工作正常,但使用命令提示符运行mvn spring-boot:run我收到这些错误:

我收到了所有邮件,但我想根据日期提取邮件.

我正在 ubuntu 16.04 xenial .zookeeper 上安装 mesosphere，并且 mesos-master 和 mesos-slave 运行良好，而开始马拉松时我遇到了这个问题。 找不到必需的选项“master”。我在 /etc/marathon/conf 中创建了文件夹。这些是我为 marathon 遵循的步骤。

sudo mkdir -p /etc/marathon/conf
sudo cp /etc/mesos-master/hostname /etc/marathon/conf
sudo cp /etc/mesos/zk /etc/marathon/conf/master
sudo cp /etc/marathon/conf/master /etc/marathon/conf/zk
sudo nano /etc/marathon/conf/zk ,edit mesos to marathon in the end .
