java - spring-boot在@ResponseBody返回json时的时间处理

Question

在application.properties增加

spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.joda-date-time-format=yyyy-MM-dd HH:mm:ss

但是并没有生效，返回的时间依然是long型的时间戳。并且我是想把这里的dataFormat改成动态的，但是加了以后一直在报错。我先把我的代码贴一下，看看哪位朋友可以帮忙解决。

Answer 1

customObjectMapper Dari mana datangnya objek ini? Jika anda menciptanya sendiri, tetapkannya terus melalui ObjectMapper Jika tidak, anda harus menggunakan kaedah penciptaan konfigurasi spring-boot untuk menggunakan konfigurasi.

Answer 2

Masalah telah selesai. Berkaitan dengan anotasi kelas permulaan but spring

Answer 3

Selesai, mengapa anda tidak menulisnya dengan jelas. Saya juga menghadapi masalah ini, ia sangat menjengkelkan
