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直接改稱Date

    private Date gmtCreate;

    private Date gmtModified;

 

方案三

pom.xml添加依賴

        <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自定義配置項目

 

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配置類

package com.example.demo.config;

import java.time.LocalTime;
import java.time.format.DateTimeFormatter;

    String localTimeFormat;

    @Bean
    public ObjectMapper objectMapper() {
        ObjectMapper om = new ObjectMapper();
        JavaTimeModule javaTimeModule = new JavaTimeModule();
        javaTimeModule.addSerializer(LocalDateTime.class,
            new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(localDateTimeFormat)));
        javaTimeModule.addSerializer(LocalDate.class,

        javaTimeModule.addSerializer(LocalTime.class,
            new LocalTimeSerializer(DateTimeFormatter.ofPattern(localTimeFormat)));

        javaTimeModule.addDeserializer(LocalDateTime.class,
            new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(localDateTimeFormat)));
        javaTimeModule.addDeserializer(LocalDate.class,
            new LocalDateDeserializer(DateTimeFormatter.ofPattern(localDateFormat)));
        javaTimeModule.addDeserializer(LocalTime.class,
            new LocalTimeDeserializer(DateTimeFormatter.ofPattern(localTimeFormat)));
        om.registerModule(javaTimeModule);
        return om;
    }
