类型不匹配消息的弹簧使用 [英] Spring usage of typeMismatch messages

问题描述

我已经在网络和stackoverflow上进行了一些搜索，看看如何处理我的一个屏幕上的以下消息：

无法将属性值
将[java.lang.String]类型转换为必需的
类型[java.lang.Long] for property
'qtyToShip';嵌套异常是
java.lang.IllegalArgumentException：
无法解析数：Unparseable
number：a

从研究和从网站看，我假设将以下内容添加到我的errors.properties文件将产生所需的结果：

  typeMismatch.shippingCommand.qtyToShip = 1。数量要发送的值无效，只接受数字。 
 typeMismatch.qtyToShip = 2。数量要发送的值无效，只接受数字。 
 shippingCommand.qtyToShip = 3。数量要发送的值无效，只接受数字。 
 qtyToShip = 4。数量要发送的值无效，只接受数字。 
 
 
 typeMismatch.java.lang.NumberFormatException = 5。 {0}的值无效，只接受数字。 
 typeMismatch.java.lang.Integer =必须指定一个整数值。 
 typeMismatch.java.lang.Long =必须指定整数值。 
 typeMismatch.java.lang.Float =必须指定一个十进制值。 
 typeMismatch.java.lang.Double =必须指定一个十进制值。 
 typeMismatch.int =输入的号码无效
 typeMismatch =输入的类型无效
  

I为消息添加整数值以确定哪一个将显示。

现在我的JSP顶部有以下内容：

 < center> 
< spring：hasBindErrors name =shippingCommand> 
< c：if test =$ {errors.errorCount> 0}> 
< h4>以下错误需要更正：< / h4> 
< font color =red> 
< c：forEach items =$ {errors.allErrors}var =error> 
< spring：message code =$ {error.code}arguments =$ {err.arguments}text =$ {error.defaultMessage}/>< br /> 
< / c：forEach> 
< / font> 
< / c：if> 
< / spring：hasBindErrors> 
< / center> 
  

以上是我窗体外，我的窗体我有以下（测试理想）所以结果是当我运行我的代码来触发错误时，我看到这个在我的表单内，我收到以下消息：

  1。数量要发送的值无效，只接受数字。 
  

哪个来自：typeMismatch.shippingCommand.qtyToShip

表单外部显示：

 输入的类型无效
  / pre> 
 
 
我不明白为什么我可以在我的表单中显示正确的消息，但不在外面？
 
 
 
在控制器中我添加了以下内容：
  @Override 
 protected void initBinder（HttpServletRequest pRequest， ServletRequestDataBinder pBinder）throws异常
 {
 NumberFormat numberFormat = NumberFormat.getInstance（）; 
 pBinder.registerCustomEditor（Long.class，qtyToShip，新的CustomNumberEditor（Long.class，numberFormat，false））; 
} 
  
感谢
解决方案
也许 error.code 不保证返回最具体的消息代码。尝试传递错误消息作为一个整体：
 < spring：message message =$ {error}/> 
  
 
I have done some searches on the web and in stackoverflow to see how to handle the following message that I get on one of my screens:

  
Failed to convert property value of
  type [java.lang.String] to required
  type [java.lang.Long] for property
  'qtyToShip'; nested exception is
  java.lang.IllegalArgumentException:
  Could not parse number: Unparseable
  number: "a"
From research and from looking at the web I assumed that adding the following to my errors.properties file would produce the desired results:
typeMismatch.shippingCommand.qtyToShip=1. Invalid value for Qty To Ship, accepts only numbers.  
typeMismatch.qtyToShip=2. Invalid value for Qty To Ship, accepts only numbers. 
shippingCommand.qtyToShip=3. Invalid value for Qty To Ship, accepts only numbers. 
qtyToShip=4. Invalid value for Qty To Ship, accepts only numbers.


typeMismatch.java.lang.NumberFormatException=5. Invalid value for {0}, accepts only numbers. 
typeMismatch.java.lang.Integer=Must specify an integer value. 
typeMismatch.java.lang.Long=Must specify an integer value. 
typeMismatch.java.lang.Float=Must specify a decimal value. 
typeMismatch.java.lang.Double=Must specify a decimal value.  
typeMismatch.int=Invalid number entered 
typeMismatch=Invalid type entered
I add integer values to the message to determine which one would show up.

Now at the top of my JSP I have the following:
  <center>
    <spring:hasBindErrors name="shippingCommand">
      <c:if test="${errors.errorCount > 0 }">
        <h4>Following errors need to be corrected:</h4>
        <font color="red">
          <c:forEach items="${errors.allErrors}" var="error">
            <spring:message code="${error.code}" arguments="${err.arguments}" text="${error.defaultMessage}"/><br />
          </c:forEach>
        </font>
      </c:if>
    </spring:hasBindErrors>
  </center>
The above is outside my Form, inside my Form I have the following (testing out ideals)


    

So the results is that when I run my code to trigger the error, I see that inside my form I get the following message:
1. Invalid value for Qty To Ship, accepts only numbers.
Which comes from this:  typeMismatch.shippingCommand.qtyToShip

The outside of the form displayes:
Invalid type entered
What I do not understand is why am I able to display the correct message inside my form but not outside?

In the controller I have added the following:
@Override
protected void initBinder(HttpServletRequest pRequest, ServletRequestDataBinder pBinder) throws Exception
{
    NumberFormat numberFormat = NumberFormat.getInstance();
    pBinder.registerCustomEditor(Long.class, "qtyToShip", new CustomNumberEditor(Long.class, numberFormat, false));
}
Thanks
解决方案
Perhaps error.code doesn't guarantee to return the most specific message code. Try to pass error message as a whole:
<spring:message message = "${error}" />
