本文介绍了typeMismatch 消息的 Spring 用法的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在网络和 stackoverflow 中进行了一些搜索，以了解如何处理我在其中一个屏幕上收到的以下消息:

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:

无法转换属性值输入 [java.lang.String] 到需要输入 [java.lang.Long] 作为属性'qtyToShip';嵌套异常是java.lang.IllegalArgumentException:无法解析数字:无法解析编号:a"

从研究和网上看，我认为将以下内容添加到我的 errors.properties 文件会产生预期的结果:

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

我将整数值添加到消息中以确定将显示哪个.

I add integer values to the message to determine which one would show up.

现在在我的 JSP 顶部，我有以下内容:

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>

以上在我的表格之外，在我的表格内我有以下内容(测试理想)

The above is outside my Form, inside my Form I have the following (testing out ideals)

所以结果是，当我运行我的代码来触发错误时，我看到在我的表单中我收到以下消息:

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.

来源于此:typeMismatch.shippingCommand.qtyToShip

Which comes from this: typeMismatch.shippingCommand.qtyToShip

表格外侧显示:

Invalid type entered

我不明白的是为什么我可以在表单内显示正确的消息，但在表单外却不能显示?

What I do not understand is why am I able to display the correct message inside my form but not outside?

在控制器中我添加了以下内容:

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));
}

谢谢
