springboot项目中统一时间格式处理方法
作者:飞翔的小->子>弹->
JacksonConfiguration主要用于配置JSON的序列化和反序列化,而LocalDateTimeFormatter则用于处理请求和响应中的LocalDateTime格式,这两个配置项在SpringBoot项目中至关重要,确保数据格式的正确处理和传输
JacksonConfiguration:
主要用于配置 Jackson 的序列化和反序列化,影响 JSON 请求和响应的内容。适用于处理 JSON 数据的序列化和反序列化
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;
import com.fasterxml.jackson.databind.deser.std.StringDeserializer;
import com.fasterxml.jackson.databind.module.SimpleModule;
import com.fasterxml.jackson.databind.ser.std.ToStringSerializer;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateTimeDeserializer;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateTimeSerializer;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.io.IOException;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
@Configuration
public class JacksonConfiguration {
@Value("${spring.jackson.date-format}")
private String dateTimeFormat;
@Bean
public Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {
return builder -> {
builder.deserializerByType(Long.TYPE, StringDeserializer.instance);
builder.serializerByType(Long.class, ToStringSerializer.instance);
builder.serializerByType(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(dateTimeFormat)));
builder.deserializerByType(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(dateTimeFormat)));
SimpleModule module = new SimpleModule();
module.addKeySerializer(LocalDateTime.class, new JsonSerializer<>() {
final DateTimeFormatter FORMATTER = DateTimeFormatter.ofPattern(dateTimeFormat);
@Override
public void serialize(LocalDateTime value, JsonGenerator gen, SerializerProvider serializers) throws IOException {
gen.writeFieldName(FORMATTER.format(value));
}
});
builder.modules(module);
};
}
}LocalDateTimeFormatter:
主要用于处理 Spring MVC 中的请求参数和响应体中的 LocalDateTime。它直接影响 Controller 方法中参数的解析和返回值的格式化。
import org.springframework.context.annotation.Configuration;
import org.springframework.format.Formatter;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.Locale;
@SuppressWarnings("NullableProblems")
@Configuration
public class LocalDateTimeFormatter implements Formatter<LocalDateTime> {
public static final String DATA_TIME_FORMAT = "yyyy-MM-dd HH:mm:ss.SSS";
public static final String DATA_TIME_FORMAT_T = "yyyy-MM-dd'T'HH:mm:ss.SSS";
@Override
public LocalDateTime parse(String text, Locale locale) {
return LocalDateTime.parse(text, DateTimeFormatter.ofPattern(DATA_TIME_FORMAT));
}
@Override
public String print(LocalDateTime object, Locale locale) {
return DateTimeFormatter.ofPattern(DATA_TIME_FORMAT).format(object);
}
