JSON parse error: Cannot deserialize value of type `java.time.LocalDateTime-蒲公英云

JSON parse error: Cannot deserialize value of type `java.time.LocalDateTime

方案一

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

方案二

LocalDateTime直接改称Date

private Date gmtCreate;
    private Date gmtModified;

方案三

pom.xml添加依赖

<dependency>
            <groupId>com.fasterxml.jackson.datatype</groupId>
            <artifactId>jackson-datatype-jsr353</artifactId>
            <version>2.11.0</version>
            <type>bundle</type>
        </dependency>

添加application.yml自定义配置项目

spring:
  jackson:
    local-date-time-format: yyyy-MM-dd HH:mm:ss
    local-date-format: yyyy-MM-dd
    local-time-format: HH:mm:ss

添加jackson配置类
