参数转换错误。报400

自定义类型转换器：

package com.lagou.edu.converter;
    
    import org.springframework.core.convert.converter.Converter;
    
    import java.text.ParseException;
    
    import java.text.SimpleDateFormat;
    
    import java.util.Date;
    
    /**
    
    * @author lyj
    
    * @Title: DateConverter
    
    * @ProjectName springmvc-demo
    
    * @Description: 自定义类型转换器，自定义完后需要注册
    
    * @date 2020/6/10 23:10
    
    */
    
    
    
    public class DateConverter implements Converter<String, Date> {
    
        @Override
    
        public Date convert(String s) {
    
            SimpleDateFormat simpleDateFormat=new SimpleDateFormat("yyyy-MM-dd");
    
            Date parse = null;
    
            try {
    
                parse = simpleDateFormat.parse(s);
    
            } catch (ParseException e) {
    
                e.printStackTrace();
    
            }
    
    
    
    
    
            return parse;
    
        }
    
    }

springmvc.xml中注册

<mvc:annotation-driven conversion-service="conversionServiceBean"/>
    
    
    
        <bean id="conversionServiceBean" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
    
            <property name="converters">
    
                <set>
    
                    <bean class="com.lagou.edu.converter.DateConverter"></bean>
    
                </set>
    
            </property>
    
        </bean>

问题：对于同一个项目中多个日期格式的，我们可以定义多个日期转换器，但是没有必要，我们可以在DateConverter转换器中catch中捕捉异常的时候再new一个新的simpleFormat的转换对象，继续进行转换。
