HTTP Status 400 - n The request sent by the client was syntactically incorrect.

控制台报错:org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 1 errors

(string 无法绑定 date)

1.写一个类继承Converter

public class DateConvert implements Converter<String, Date> {


	@Override
	public Date convert(String stringDate) {
		   SimpleDateFormat simpleDateFormat =null;
	        if(stringDate.length()==10) {
	            simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd");
	        }
	        else  if(stringDate.length()>10)
	        {
	            simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
	        }
	        try {
	            return simpleDateFormat.parse(stringDate);
	        } catch (Exception e) {
	            e.printStackTrace();
	        }
	        return null;
	    }
	}

2.在springmvc.xml中配置这个类

<bean id="conversionService"
        class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
        <property name="converters">
            <list>
                <bean class="com.fish.controller.DateConvert" />
            </list>
        </property>
    </bean> 

<mvc:annotation-driven conversion-service="conversionService" >
<!-- 这段代码时处理responseBody 里面日期类型，不然是一串数字，和上面的代码无关可以加上，用的到 -->  
        <mvc:message-converters>  
            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">  
                <property name="objectMapper">  
                    <bean class="com.fasterxml.jackson.databind.ObjectMapper">  
                        <property name="dateFormat">  
                            <bean class="java.text.SimpleDateFormat">  
                                <constructor-arg type="java.lang.String" value="yyyy-MM-dd HH:mm:ss" />  
                            </bean>  
                        </property>  
                    </bean>  
                </property>  
            </bean>  
        </mvc:message-converters>  
	 </mvc:annotation-driven>
