Add @JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss+HHmm") to Date in EventCommit

Google translation:

As the title says, add `@jsonformat(pattern = "yyyy-MM-dd'T'HH:mm:ss+HHmm")` to Date in EventCommit class

The project uses `yyyy-MM-dd HH:mm:ss` by default, and an error will be reported when receiving an object.

original message:

如题EventCommit 类中的Date 增加@JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss+HHmm")
项目中默认使用yyyy-MM-dd HH:mm:ss ， 接收对象时会报错。
