问题描述

在做项目时遇到问题：



后台报错：

Resolved [org.springframework.http.converter.HttpMessageNotReadableException:

JSON parse error: Cannot deserialize value of type

java.time.LocalDateTime

from String “2023-03-11 09:00:00”:

nested exception is com.fasterxml.jackson.databind.exc.InvalidFormatException:

from String “2023-03-11 09:00:00”:

line: 4, column: 17] (through reference chain: com.cxz.springdemo02.Entity.ProcessingBatch[“startTime”])]

问题解决：

在实体类的字段加上@JsonFormat即可

	@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm:ss")
    private LocalDateTime startTime;

   @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm:ss")
    private LocalDateTime endTime;
