@DateTimeFormat & @JsonFormat

• @DateTimeFormat(pattern = “yyyy-MM-dd”)
• @JsonFormat(timezone = “GMT+8”, pattern = “yyyy/MM/dd”)

@DateTimeFormat其实是作为Formatter被注册到ConvertionService中了
@JsonFormat被MappingJackson2HttpMessageConverter处理

@DateTimeFormat 处理：

    POST /testdate3 HTTP/1.1
    Host: localhost:8082
    Content-Type: application/x-www-form-urlencoded
    Cache-Control: no-cache
    Postman-Token: c764abc6-768e-dab0-f46a-19037c33921a
    name=asdf&date=2018-11-2+2%3A22%3A2

@JsonFormat处理：

    POST /testdate HTTP/1.1
    Host: localhost:8082
    Content-Type: application/json
    Cache-Control: no-cache
    Postman-Token: e9017210-0f4d-c86c-51c8-18f7ccafc93d
    {"name":"aaaa","id":1,"date":"2018/11/2 2:22:2"}
