java - 非常简单的字符串替换失败

Question

final String message =
                        "Please enter the following code in the password reset screen:\n" +
                                "\n"+
                                "{CODE} (((((" + codeStr + ")))))\n" +
                                "If you didn't ask for this code, or don't know what this e-mail is about, you can safely ignore it."
                                .replace("{CODE}", codeStr);

这会导致

Please enter the following code in the password reset screen: {CODE} (((((5RE2GT4FWH))))) If you didn't ask for this code, or don't know what this e-mail is about, you can safely ignore it.

这么简单的替换怎么会不起作用呢？我认为问题可能在于 {CODE} 的两个实例看起来很相似，但实际上由不同的字符组成，但我将一个复制粘贴到另一个上，但没有解决问题。

问即知:

final String message =
                    (
                            "Please enter the following code in the password reset screen:\n" +
                            "\n"+
                            "{CODE}" + codeStr + "\n" +
                            "If you didn't ask for this code, or don't know what this e-mail is about, you can safely ignore it."
                    )
                    .replace("{CODE}", codeStr);

由于缺少括号，所以先对组成字符串的最后部分进行替换，然后才将各部分连接在一起。
