使用MessageFormat的转义双引号

Question

I have the following String in JSON format:

String message = "{ \"message\": \"Hello World!\" }";

But I want to set it up to use MessageFormat:

String message = MessageFormat.format("{ \"message\": \"Hello {0}!\" }", "World");

I know MessageFormat uses single quotes vs backslash to escape characters, but I am not seeing a way around using a backslash here since I need the double quotes in the message and without the backslash, the unescaped double quotes break the string.

Any idea how to get this to work?

Answer 1

您应该将大括号转义，所以将{和}放在单引号中：

 String message = MessageFormat.format("'{' \"message\": \"Hello {0}!\" '}'", "World");

Answer 2

使用两个转义字符作为转义字符，并使用转义的引号作为引号。

String message = MessageFormat.format("{ \\\"message\\\": \\\"Hello {0}!\\\" }", "World");
