Springboot序列化和反序列化LocalDateTime

一、注解方式
1.出参

@Data 
@ApiModel 
public class ResVO { 
	@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",shape=JsonFormat.Shape.STRING) 
	@ApiModelProperty(name="dateTime",value="日期",example="2020-03-17 12:07:00") 
	private LocalDateTime dateTime; 
} 

2.入参
a.Date类型

@Data 
@ApiModel(description="入参对象",value="rucna") 
public class ReqVO { 
	@JsonFormat(pattern="yyyy-MM-dd") 
	@ApiModelProperty(name="dateTime",required=true,example="2020-12-10") 
	private Date dateTime; 
} 

b.LocalDateTime类型

public class DateDeserializer extends JsonDeserializer<LocalDateTime> { 
 
    @Override 
    public LocalDateTime deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException, JsonProcessingException { 
    	if (StringUtils.isBlank(jsonParser.getText())) 
            return null; 
        LocalDate localDate = LocalDate.parse(jsonParser.getText(), DateTimeFormatter.ofPattern("yyyy-MM-dd")); 
        return LocalDateTime.of(localDate, LocalTime.MIN); 
    } 
} 
@Data 
@ApiModel(description="入参对象",value="rucna") 
public class ReqVO { 
	@JsonDeserialize(using = DateDeserializer.class) 
	@ApiModelProperty(name="dateTime",required=true,example="2020-12-10") 
	private LocalDateTime dateTime; 
} 

3.入参

4.出参

二、全局方式
1.配置类

@Configuration 
public class LocalDateTimeConfig { 
	@Bean 
	public Jackson2ObjectMapperBuilderCustomizer customizeLocalDateTimeFormat(@Value("${spring.jackson.date-format}") String pattern) { 
		return jacksonObjectMapperBuilder -> { 
			DateTimeFormatter formatter = DateTimeFormatter.ofPattern(pattern); 
			LocalDateTimeDeserializer deserializer = new LocalDateTimeDeserializer(formatter); 
			LocalDateTimeSerializer serializer = new LocalDateTimeSerializer(formatter); 
			jacksonObjectMapperBuilder.serializerByType(LocalDateTime.class, serializer); 
			jacksonObjectMapperBuilder.deserializerByType(LocalDateTime.class, deserializer); 
		}; 
	} 
} 

2.测试demo

	@PostMapping("/testDate") 
	@ApiOperation(value="测试时间格式化", notes="") 
	public ResVo login2(@RequestBody ReqVo req) 
	{ 
		System.out.println(JSONObject.toJSONString(req)); 
		LocalDateTime date = req.getDate(); 
		LocalDateTime plusHours = date.plusHours(2); 
		ResVo resVo = new ResVo(); 
		resVo.setDate(plusHours); 
		resVo.setId(18); 
		return resVo; 
	} 

@ApiModel 
@Data 
public class ReqVo { 
	@ApiModelProperty(name="date",value="时间") 
	private LocalDateTime date; 
	@ApiModelProperty(name="id",value="序号") 
	private Integer id; 
}
