SpringMVC中的400错误，The request sent by the client was syntactically incorrect.

 

 

在其他对象属性类型一样情况下，只需要创建一个类，再在springmvc.xml中添加配置：

 

package com.ujiuye.common;

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

import java.text.SimpleDateFormat;
import java.util.Date;

public class DateTimeConverter implements Converter<String, Date> {
    public Date convert(String s) {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        try{
            Date date = sdf.parse(s);
            return date;
        }catch (Exception ex){
            System.out.println(ex.getMessage());
            return null;
        }
    }
}

 

 

 

<!--全局类型转型器-->
    <bean id="converter" class="com.ujiuye.common.DateTimeConverter"></bean>
    <bean id="formattingConversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
        <property name="converters">
            <set>
                <ref bean="converter"></ref>
