如何在messages.properties文件中使用参数？

Question

在这个问题中,它指出,有可能有类似的东西:

message.myMessage = This message is for {0} in {1}

但我不知道如何将参数传递给它

MESSAGES.getString("message.myMessage", "foor", "bar")

但不幸的是getString无法知道拿其他参数有什么想法吗？

Answer 1

我猜你在想MessageFormat？如果是这样,就是这样:

String s = MessageFormat.format("This message is for {0} in {1}", "foo", "bar");

或者从属性:

Properties p = new Properties();
p.setProperty("messages.myMessage", "This message is for {0} in {1}");
String s = MessageFormat.format(
    p.getProperty("messages.myMessage"), "foo", "bar");

Answer 2

试试这个:

String message = "This message is for {0} in {1}.";
String result = MessageFormat.format(message, "me", "the next morning");
System.out.println(result);

(java.text.MessageFormat;)

或者在JSF中:

<h:outputFormat value="This message is for {0} in {1}.">
    <f:param value="me">
    <f:param value="the next morning">
</h:outputFormat>
