SpringBoot接收LocalDateTime参数的方式
目录
- 一、通过@RequestBody接收
- 二、通过@RequestParam接收
一、通过@RequestBody接收
方式1:实体类上加上 @jsonFormat,并通过 pattern 属性指定时间格式
public class Time { @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss") LocalDateTime localDateTime; @JsonFormat(pattern = "yyyy-MM-dd") LocalDate localDate; @JsonFormat(pattern = "HH:mm:ss") LocalTime localTime; }
方式二:配置Jackson时间序列化,创建如下配置类即可
import com.fasterXML.jackson.databind.ObjectMapper; import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule; import com.faandroidsterxml.jackson.datatype.jsr310.deser.LocalDateDeserializer; import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateTimeDeserializer; import com.fasterxml.jackson.datatype.jsr310.deser.LocalTimeDeserializer; import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateSerializer; import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateTimeSerializer; import com.fasterxml.jackson.datatype.jsr310.ser.LocalTimeSerializer; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import java.time.LocalDate; import java.time.LocalDateTime; import java.time.LocalTime; import java.time.format.DateTimeFormatter; @Configuration public class JacksonConfig { @Bean public ObjectMapper objectMapper() { JavaTimeModule javaTimeModule = new JavaTimeModule(); // 时间序列化 javaTimeModule.addSerializer(LocalDateTime.class,new LocalDateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))); javaTimeModule.addSerializer(LocalDate.class,new LocalDateSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd"))); javaTimeModule.addSerializer(LocalTime.class,new LocalTimeSerializer(DateTimeFormatter.ofPattern("HH:mm:ss"))); // 时间反序列化 javaTimeModule.addDeserializer(LocalDateTime.class,new Locawww.devze.comlDateTimeDeserializer(DateTimeFormatter编程.ofPattern("yyyy-MM-dd HH:mm:ss"))); javaTimeModule.addDeserializer(LocalDate.class,new LocalDateDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd"))); javaTimeModule.addDeserializer(LocalTime.class,new LocalTijavascriptmeDeserializer(DateTimeFormatter.ofPattern("HH:mm:ss"))); ObjectMapper objectMapper = new ObjectMapper(); objectMapper.registerModule(javaTimeModule); return objectMapper; } }
二、通过@RequestParam接收
方式1:在参数前面加上 @DateTimeFormat 注解,通过 pattern 属性指定时间格式
@GetMapping("/param/local") public void testLocalDateTime(@RequestParam @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss") LocalDateTime localDateTime, @RequestParam @DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate localDate, @RequestParam @DateTimeFormat(pattern = "HH:mm:ss") LocalTime localTime) { }
方式2:配置时间格式转换器,创建如下配置类即可
import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.core.convert.converter.Converter; import java.time.LocalDate; import java.time.LocalDateTime; import java.time.LocalTime; import java.time.format.DateTimeFormatter; /** * 日期格式转换器配置 */ @Configuration public class DateConverterConfig { /** * LocalDateTime格式转换器 */ @Bean public Converter<String, LocalDateTime> localDateTimeConverter() { return new Converter<String, LocalDateTime>() { @Override public LocalDateTime convert(String timeStr) 编程{ return LocalDateTime.parse(timeStr,DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")); } }; } /** * LocalDate格式转换器 */ @Bean public Converter<String, LocalDate> localDateConverter() { return new Converter<String, LocalDate>() { @Override public LocalDate convert(String timeStr) { return LocalDate.parse(timeStr,DateTimeFormatter.ofPattern("yyyy-MM-dd")); } }; } /** * LocalTime格式转换器 */ @Bean public Converter<String, LocalTime> localTimeConverter() { return new Converter<String, LocalTime>() { @Override public LocalTime convert(String timeStr) { return LocalTime.parse(timeStr,DateTimeFormatter.ofPattern("HH:mm:ss")); } }; } }
