java - 包含单引号时，MessageFormat 不格式化

Question

我正在传递由 {} 填充符和文本组合而成的文本。我正在尝试用一些值填充 {} 并尝试使用 MessageFormat。

String sss = "{0}SomeText{1}\'.{2}SomeText{2}SomeText{0}{0}SomeText{2}{0}SomeText{0}{1}SomeText{0}{2}{0}{0}{1}{0}{2}{0}{0}{2}{0}{0}{1}{0}{2}{0}";

Object[] testArgs = {"nits1", "Nits2","nits#"};

System.out.println(MessageFormat.format(sss,testArgs));

输出

nits1SomeTextNits2.{2}SomeText{2}SomeText{0}{0}SomeText{2}{0}SomeText{0}{1}SomeText{0}{2}{0}{0}{1}{0}{2}{0}{0}{2}{0}{0}{1}{0}{2}{0}

Answer 1

必须使用双单引号对单引号进行转义：

String sss = "{0}SomeText{1}''.{2}S..."

Answer 2

我的错误是，我没有使用方法'format(..)'的返回值

错误代码：

MessageFormat.format(sss, testArgs);
System.out.println(sss);

正确代码：

String newString = MessageFormat.format(sss, testArgs);
System.out.println(newString);
