从 JSTL 读取属性文件
我正在尝试使用 taglib 读取 JSTL 形式的“属性文件”，但我无法访问它
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt"%>
我已在 web.xml 中正确找到了 tld 文件，我确信
<taglib>
<taglib-uri>http://java.sun.com/jstl/fmt</taglib-uri>
<taglib-location>/WEB-INF/lib/fmt.tld</taglib-location>
</taglib>
属性文件名是 msg。 属性
<fmt:bundle basename="msg">
<fmt:message key="error.more" />
</fmt:bundle>
我不断收到
???error.more???
而不是属性文件中的消息
我认为问题在于定位属性文件， 或者在基本名称中
<fmt:bundle basename="msg">
我应该在哪里找到属性文件，以及如何在代码中引用它？
谢谢大家
I am trying to read a "properties file" form JSTL using taglib , but i can't access it
<%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt"%>
I've located the tld file correctly in the web.xml , am sure of this
<taglib>
<taglib-uri>http://java.sun.com/jstl/fmt</taglib-uri>
<taglib-location>/WEB-INF/lib/fmt.tld</taglib-location>
</taglib>
The properties file name is msg. properties
<fmt:bundle basename="msg">
<fmt:message key="error.more" />
</fmt:bundle>
I keep getting
???error.more???
instead of the message in properties file
I think the problem is either in locating the properties file ,
or in the base name in
<fmt:bundle basename="msg">
where should I locate the properties file , and how can I make a reference to it in the code??
thanks everyone

这是错误的 URI。这是针对已经过时很长时间的旧 JSTL 1.0。对于 JSTL 1.1，您应该使用
http://java.sun.com/jsp/jstl/fmt。当您修复 taglib URL 时这是不必要的。从您的
web.xml中删除它，并删除所有那些松散的 TLD 文件。您应该在/WEB-INF/lib中只有jstl.jar和standard.jar。或者，当您使用 JSTL 1.2 时，只需jstl-1.2.jar。无需再做任何事情。另请参阅：
将其放在类路径中。在您的特定情况下，使用基本名称
msg，您需要将msg.properties文件放在类路径的根目录中。另请参阅：
This is the wrong URI. This is for the old JSTL 1.0 which is out of life for long. For JSTL 1.1 you should be using
http://java.sun.com/jsp/jstl/fmt.This is unnecessary when you fix the taglib URL. Remove it from your
web.xmland remove all those loose TLD files as well. You should just havejstl.jarandstandard.jarin/WEB-INF/lib. Or when you're using JSTL 1.2, just thejstl-1.2.jar. Nothing more needs to be done.See also:
Put it in the classpath. In your particular case, with the base name
msg, you need to put themsg.propertiesfiles in the root of the classpath.See also:

1) 我应该在哪里找到属性文件？
您必须将属性文件保存在 src 目录中。例如，您有两个名为英语和丹麦语的属性文件
位于如下所示的包内
2) 以及如何在代码中引用它？
这将以英文打印相关的按摩
1) where should I locate the properties file?
You have to keep property files inside your src directory. For example you have two property files for English and Danish named
inside a package named like below
2) and how can I make a reference to it in the code?
This will print the relevant massage in English
正如 Isuru 所说，您必须将属性文件放在包中，就像讨论类一样。
我遇到了一个奇怪的问题，我一直在正确引用我的属性文件，但从未得到正确的输出，我发现你必须为属性包遵循相同的包名称格式，所以如果你有包：
你必须创建类似的内容：
你不能这样做
在这里你可以存储你的属性文件
然后像平常一样引用它们：

As Isuru says, you have to place the properties file in a package as if you were talking about a class.
I came with a weird problem, I had been referencing my properties file correctly but never got the correct output, what I discovered was that you have to follow the same package name format for your properties bundles, so if you have packages:
You have to create something like:
You CAN'T do
Here you can store your property files
And then referenced them as you would normally do:

这可以通过以下步骤来完成。我将 messages_en.properties 文件放在 src/main/resources 文件夹下，并使用下面的代码引用属性文件。我没有考虑任何本地化，所以没有提到任何与此相关的内容。
在jsp中引用JSTL fmt uri。<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
在jsp中引用bundle。
< fmt:bundle basename="messages_en">
< fmt:message key="error.loginfailure">
This can be done by following the below steps. I placed the messages_en.properties file under src/main/resources folder and referred the properties file using this code below. I didn't considered any localization, so didn't mentioned anything related to this.
Refer the JSTL fmt uri in jsp.<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
Refer the bundle in jsp.
< fmt:bundle basename="messages_en">
< fmt:message key="error.loginfailure">
