Question

尝试使用ProGuard对我的代码进行模糊处理。

这些是我的配置

因此。当我跑步时，没有发生任何问题。但是，如果我打开我的.jar，我只能找到一个类，内部包控制器，它只是充满了注释（我认为堆栈）和/ *错误* /标题。

我很确定这个问题与StringBuffer有关。我使用String Buffer为邮件创建一条消息。

我在另一个类中遇到同样的问题并解决了我已经改变了变量的范围。（以下代码）

由此：

private static String sendMail() {
    try { 
        StringBuffer header = new StringBuffer();
        StringBuffer footer = new StringBuffer();
       //CODE WHERE I USE header and footer
         return "Mail Disabilitata.";
    } catch (Throwable t) {
        return MyUtils.stackTrace(t);
    }
}

到这个

private static String sendMail() {
    StringBuffer header = new StringBuffer();
    StringBuffer footer = new StringBuffer();
    try { 
        //CODE WHERE I USE header and footer
         return "Mail Disabilitata.";
    } catch (Throwable t) {
        return MyUtils.stackTrace(t);
    }
}

对于我的第一堂课，这种解决方法有效。

在我的第二堂课中，（控制器，我不试图混淆的那个，正如你在我的proguard配置中看到的那样）它没有。

我很确定这是关于StringBuffer的。

或者至少（我希望不是）多个String只在一个方法中反复改变

ProGuard：StringBuffer
