LocalDateTime反序列化，LocalDateTime格式化

清疚 2021-12-23 11:45 343阅读 0赞

使用mybatis-plus的时候出现了LocalDateTime类（jdk8 中新出现的类
那么我在反序列化的时候出了问题。

我在springboot 2.1.3 中使用以下类结局问题）
用到了下面这个类解决了所有的问题。包括前端传值过来也能直接接受字符串

百度上面也猜了许许多多的坑最终换了一个spring boot的版本然后用以下的代码配置完美解决了问题

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
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 org.springframework.format.Formatter;

import java.text.ParseException;
import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;
import java.time.format.DateTimeFormatter;
import java.util.Locale;

/**

接收时间配置bean
*/
@Configuration
public class LocalDateTimeFormatConfig {

@Bean(name = “mapperObject”)
public ObjectMapper getObjectMapper() {

 ObjectMapper om = new ObjectMapper();
 JavaTimeModule javaTimeModule = new JavaTimeModule();
 javaTimeModule.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd HHss")));
 javaTimeModule.addSerializer(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern("yyyy-MM-dd")));
 javaTimeModule.addSerializer(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern("HHss")));
 om.registerModule(javaTimeModule);
 return om;

}

@Bean
public Formatter localDateFormatter() {

 return new Formatter<LocalDate>() {
     @Override
     public String print(LocalDate object, Locale locale) {
         return object.format(DateTimeFormatter.ofPattern("yyyy-MM-dd"));
     }
     @Override
     public LocalDate parse(String text, Locale locale) throws ParseException {
         return LocalDate.parse(text, DateTimeFormatter.ofPattern("yyyy-MM-dd"));
     }
 };

}

     }
     @Override
     public LocalDateTime parse(String text, Locale locale) throws ParseException {
         return LocalDateTime.parse(text, DateTimeFormatter.ofPattern("yyyy-MM-dd HHss"));
     }

}
