Vue 前端向Java后台传递时间格式数据，进行数据查询，出现这个错误信息

Resolved [org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type ‘java.lang.String’ to required type ‘java.util.Date[]’; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [java.util.Date] for value ‘2020-03-12,2020-04-14’; nested exception is java.lang.IllegalArgumentException]

解决办法：添加转换类

import org.springframework.core.convert.converter.Converter;
import org.springframework.stereotype.Component;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
@Component
public class DateConverter implements Converter<String, Date> {
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
    @Override
    public Date convert(String source) {
        try {
            return sdf.parse(source);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return null;
    }
}
