I want to use crontab to run a task that invoke docker with -it options, and that task is run,but run docker is no result.

Crontab 运行任务中使用docker时不能使用交互模式(-ti),开始没有注意到这块，最后查询资料才发现，大意啊。

com.alibaba.fastjson.support.config.FastJsonConfig config = new com.alibaba.fastjson.support.config.FastJsonConfig();
		config.setSerializerFeatures(SerializerFeature.PrettyFormat, SerializerFeature.WriteMapNullValue);
		config.setDateFormat("yyyy-MM-dd HH:mm:ss");

 @JSONField(format="yyyy-MM-dd@HH:mm:ss.SSSZ")
    public Date getCreateTime() {
 return createTime;

打开windows salver下的jenkins-slaver.xml,寻找下列段落:

...
<arguments>-Xrs  -jar "%BASE%\slave.jar" ...
...

添加jvm properties,指定字符集:

-Dfile.encoding=utf-8 -Dsun.jnu.encoding=utf-8

方法

新建一个文件,生成一个文件系统,然后加载此文件系统,作为samba文件的存放位置.达到限制文件大小的目的.

优点

简单明了,限制文件大小

缺点

docker run --rm -e JAVA_OPTS='-agentlib:jdwp=transport=dt_socket,address=46029,suspend=n,server=y' -p 46029:46029 containername

注意: 需要把调试端口开放出来.

Git 协作流程

master 分支

master 永远处于稳定状态，这个分支代码可以随时用来部署。不允许在该分支直接提交代码。

develop 分支

开发分支，包含了项目最新的功能和代码，所有开发都在 develop 上进行。一般情况下小的修改直接在这个分支上提交代码。

	1. use git flow init in a exists repo (already has many branches).

	2. this command done with a message: "Production and integration branches should differ."

	3. try use "git flow init -d" , "git flow init -f ", or poen .git/config to delete all prefix with "git flow",and retry "git flow init", .problem not resolve.

	finally，I manual create develop branch(master already exists), and then "git flow init -f -d", then problem resolved.

	Spring Boot 2.1.2.RELEASE

	Spring boot App must extends SpringBootServletInitializer

	so web container can recognize the web config.

	1. mysql create database use utf8mb4 collation utf8mb4_general_ci, and then import tables with charset=utf8mb4 with out setting collation;
	2. the imported tables has use the default utf8mb4 collation utf8mb4_0900_ai_ci but not the database used;

	solution: change database collation to utf8mb4_0900_ai_ci, solved the above problem.
