不是很了解当前项目的状态，Example 都编译不过？

编译 go-spring-boot-demo ，报以下错误

go: downloading github.com/golang-jwt/jwt v3.2.2+incompatible
# github.com/go-spring/spring-core/dync
../../spring/spring-core/dync/dync.go:80:22: too many arguments in call to conf.Flatten
	have (string, interface {}, map[string]string)

../../spring/spring-core/dync/dync.go:82:4: cannot use err (type map[string]string) as type error in return argument:
	map[string]string does not implement error (missing Error method)

😝 主分支上的代码有时候重构可能编译不过，check 已发布的版本就好了。

项目当前至年底的状态是：不再增加新功能，对已有代码添加单元测试和英文文档，在这个过程中可能出现小修改。
