SpringMVC自定义类型转换器（让jsp支持2018-8-8转化成date类型）

package converter;

import java.sql.Date;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;

import javax.management.RuntimeErrorException;
import javax.xml.crypto.Data;

import org.springframework.context.support.ConversionServiceFactoryBean;
import org.springframework.core.convert.converter.Converter;

public class date_converter implements Converter<String, java.util.Date> {

    @Override
    public java.util.Date convert(String arg0) {
        if (arg0 == null) {
            throw new RuntimeException("空值");
        }
        DateFormat dFormat = new SimpleDateFormat("yyyy-MM-dd");
        try {
            return  dFormat.parse(arg0);
        } catch (ParseException e) {
            throw new RuntimeException("错误");
        }

    }

}
