jackson序列化时间
Date
spring:
jackson:
# 格式化设置
date-format: "yyyy-MM-dd HH:mm:ss.SSS"
# 时区
time-zone: "GMT+8"
LocalDateTime 和 LocalDate
import java.time.format.DateTimeFormatter;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateDeserializer;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateTimeDeserializer;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateSerializer;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateTimeSerializer;
@Configuration
public class JacksonConfiguration {
@Bean
public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
return builder -> {
// 格式
DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
//反序列化
builder.deserializers(new LocalDateDeserializer(dateFormatter));
builder.deserializers(new LocalDateTimeDeserializer(dateTimeFormatter));
// 序列化
builder.serializers(new LocalDateSerializer(dateFormatter));
builder.serializers(new LocalDateTimeSerializer(dateTimeFormatter));
};
}
}
ZonedDateTime

@Override
public void serialize(ZonedDateTime value, JsonGenerator gen, SerializerProvider serializers) throws IOException {

}
});
builder.deserializers(new StdDeserializer<>(ZonedDateTime.class) {

@Override

}
});
};
