SpringBoot接收LocalDateTime参数
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.fasterxml.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 LocalDateTimeDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));
javaTimeModule.addDeserializer(LocalDate.class,new LocalDateDeserializer(DateTimeFormatter.ofPattern("yyyy-MM-dd")));
javaTimeModule.addDeserializer(LocalTime.class,new LocalTimeDeserializer(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) {
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"));
}
};
}
}
