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 {@Beanpublic 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*/@Beanpublic Converter<String, LocalDateTime> localDateTimeConverter() {return new Converter<String, LocalDateTime>() {@Overridepublic LocalDateTime convert(String timeStr) {return LocalDateTime.parse(timeStr,DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));}};}/*** LocalDate格式转换器*/@Beanpublic Converter<String, LocalDate> localDateConverter() {return new Converter<String, LocalDate>() {@Overridepublic LocalDate convert(String timeStr) {return LocalDate.parse(timeStr,DateTimeFormatter.ofPattern("yyyy-MM-dd"));}};}/*** LocalTime格式转换器*/@Beanpublic Converter<String, LocalTime> localTimeConverter() {return new Converter<String, LocalTime>() {@Overridepublic LocalTime convert(String timeStr) {return LocalTime.parse(timeStr,DateTimeFormatter.ofPattern("HH:mm:ss"));}};}
}
