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

package com.example.demo.config;
    
    import java.time.LocalDate;
    import java.time.LocalDateTime;
    import java.time.LocalTime;
    import java.time.format.DateTimeFormatter;

    import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateTimeSerializer;
    import com.fasterxml.jackson.datatype.jsr310.ser.LocalTimeSerializer;
    
    @Configuration
    public class JacksonConfig {
    
        @Value("${spring.jackson.local-date-time-format:yyyy-MM-dd HH:mm:ss}")
        String localDateTimeFormat;
    
        @Value("${spring.jackson.local-date-format:yyyy-MM-dd}")
        String localDateFormat;
    
        @Value("${spring.jackson.local-time-format:HH:mm:ss}")
        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,
                new LocalDateSerializer(DateTimeFormatter.ofPattern(localDateFormat)));
            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;
        }
    }
