spring.jackson.date-format springboot時間格式化問題

1、如果是Date類型

 

1.1、使用JsonFormat

 

<!--  yyyy-MM-dd HH:mm:ss
    @JsonFormat(pattern = " yyyy-MM-dd HH:mm:ss", timezone = "Asia/Shanghai")
    private Date birthday;
  -->

依賴必須加入
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>2.9.0</version>
</dependency>

com.fasterxml.jackson.annotation 依賴
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>2.9.0</version>
</dependency>

 

 

1.2、使用全局配置

# 返回時間戳# 返回日期格式，字符串
#spring.jackson.serialization.write-dates-as-timestamps=true
spring.jackson.date-format =yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8

 

 

 

 

2、如果是LocalDateTime類型

 

2.1、單個配置

@JsonFormat(pattern = " yyyy-MM-dd HH:mm:ss", timezone = "Asia/Shanghai")
private LocalDateTime created;

依賴必須加入
<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-annotations</artifactId>
    <version>2.9.0</version>
</dependency>

 

2.2、全局配置

 

/**
* @author yuguang
* @date 2020/6/4 11:56
* @desc 全局時間格式化
*/
@Configuration
public class LocalDateTimeSerializerConfig {

    @Value("${spring.jackson.date-format}")
    private String pattern;

    @Bean
    public LocalDateTimeSerializer localDateTimeDeserializer() {
        return new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(pattern));
    }

    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
        return builder -> builder.serializerByType(LocalDateTime.class, localDateTimeDeserializer());
    }

}
