SpringBoot接收LocalDateTime参数的方式

作者：小小李程序员

这篇文章主要介绍了SpringBoot接收LocalDateTime参数的方式,本文通过实例代码给大家介绍的非常详细,感兴趣的朋友跟随小编一起看看吧

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"));
            }
        };
    }
}
