FastJson设置了默认日期格式后就无法使用JSONField进行设置日期格式了！！！ 
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");

Created November 27, 2018 11:44
git flow always show error : git flow fatal: Not a gitflow-enabled repo yet. Please run "git flow init" first.
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.

java.sql.SQLException: Illegal mix of collations (utf8mb4_0900_ai_ci,IMPLICIT) and (utf8mb4_general_ci,IMPLICIT) for operation '='
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.

Git 开发流程

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。
