Facelet 无法正确转换格式化货币

发布于 2024-08-27 08:12:42 字数 620 浏览 7 评论 0原文

我在 Facelet 页面中有以下代码：

<h:inputNumber value="bean.property">
    <f:convertNumber type="currency" />
</h:inputNumber

转换器是因为输入字段内可以有一种来自 bean 属性的默认值。一切都正确呈现。输入字段内的值用“€”字符呈现（例如“1.453 €”。

当我提交表单时出现错误：

"nameOfInputField" konnte nicht als ein Geldbetrag erkannt werden '304,00 â¬'

在英语中，它有点像：

"nameOfInputField" could not be regognized as an amount of money '304,00 â¬'

请看一下“€”字符。被打印为“â”。虽然在提交表单之前它已正确呈现，但现在在错误消息和输入字段中看起来像“â”。

所有页面都以 UTF-8 编码。

它似乎这个错误的原因是什么？如何修复它？

提前致谢

原文

I have the follwing code inside a facelet page:

<h:inputNumber value="bean.property">
    <f:convertNumber type="currency" />
</h:inputNumber

The converter is because there can be a kind of default value inside the input field, which comes from the bean property. Everything is rendered correctly. The value inside the input field is rendered with an "€" character (e.g. "1.453 €".

When I submit the form there comes an error up:

"nameOfInputField" konnte nicht als ein Geldbetrag erkannt werden '304,00 â¬'

In english it is some like:

"nameOfInputField" could not be regognized as an amount of money '304,00 â¬'

Please have a look at the "€" character. It seems to be printed as "â¬". While it was rendered correctly before submitting the form, now it looks like "â¬" inside the error message and inside the input field.

All pages are encoded in UTF-8.

What is the reason for this error?
How can fix it?

Thanks in advance

这是来自原始 UTF-8 源的 € 的典型情况，该源被错误地使用 ISO-8859-1 解码。这是一个小片段，它证明了这一点：

System.out.println(new String("€".getBytes("UTF-8"), "ISO-8859-1"));

所有页面均采用 UTF-8 编码。

您可能正在谈论响应编码。您还需要设置请求编码。

要设置 GET 请求的编码（基本上：URI 编码），您需要查阅应用程序服务器特定文档。由于不清楚您使用的是哪一个，这里有一个针对 Tomcat 的示例： <连接器 URIEncoding="UTF-8"/>。要设置 POST 请求的编码，您需要创建一个简单的过滤器，它执行 request.setCharacterEncoding("UTF-8") 如果为 null。更多背景信息和提示可以在这篇文章。

This is typical for the € from an original UTF-8 source which is incorrectly been decoded using ISO-8859-1. Here's a small snippet which demonstrates that:

System.out.println(new String("€".getBytes("UTF-8"), "ISO-8859-1"));

All pages are encoded in UTF-8.

You're likely talking about response encoding. You need to set the request encoding as well.

To set the encoding for GET requests (basically: URI encoding), you need to consult the appserver specific documentation. As it's unclear which one you're using, here's a Tomcat targeted example: <Connector URIEncoding="UTF-8" />. To set the encoding for POST requests, you need to create a simple filter which does request.setCharacterEncoding("UTF-8") if it is null.
