我在我的代码中找到了这样的行，如下所示
arg = remoteActionArgument.getDataType().getJavaDataType().getConstructor(new Class[] {
java/lang/String
}).newInstance(new Object[] {
strArg
});
在这里，我看到这样的 java / lang / String
我无法理解，这个结构究竟是什么。
有任何建议吗？
我尝试了以下内容
* 1. import java.lang。; *
2.更改此行以了解调用的位置，但除了此类代码外，我什么都没找到，另一个类文件

java中这样的java / lang / ....结构如何，需要帮助
由于
答案 0 :(得分：2)
在您的代码中替换：
.getConstructor(new Class[] { java/lang/String }) ...
使用：
getConstructor(new Class[] { String.class }) ...
符号java/lang/String是类String名称的内部表示。无需明确import java.lang.*;，它是隐式导入的。
答案 1 :(得分：1)
您的反编译器正在添加 java / lang / （不确定您使用的是哪个反编译器）。
如果要编译源代码。删除src中的所有java/lang/。无需导入任何默认情况下导入的java.lang。
