PMD错误

Avoid autogenerated methods to access private fields and methods of inner / outer classes

样例

public class Test {

    public static void main(final String[] args) {
//code
} public void test(){
Executors.newSingleThreadExecutor().execute(new Thread() {
@Override
public void run() {
final int a = getNum();
System.out.println(a);
}
});
} private int getNum() {
return 0;
}
}

报错原因

在匿名内部类的方法里去调用外部类的私有方法或变量就会报这个PMD错误。

解决方法

可以将匿名内部类的方法里调用到的外部类的私有方法/变量改成protected。以样例来举例,即将getNum()的权限改为protected:

protected int getNum() {
return 0;
}
