我想抑制特定字段或局部变量的FindBugs警告.FindBugs文档指出Target的edu.umd.cs.findbugs.annotations.SuppressWarning注释[1]可以是Type,Field,Method,Parameter,Constructor,Package.但是,只有当我注释警告被抑制的方法时,它才能对我进行注释.

注释整个方法似乎对我来说很广泛.有没有办法抑制特定字段的警告？还有另一个相关问题[2],但没有答案.

[2] 在Eclipse中抑制FindBugs警告

演示代码:

public class SyncOnBoxed
{
    static int counter = 0;
    // The following SuppressWarnings does NOT prevent the FindBugs warning
    @edu.umd.cs.findbugs.annotations.SuppressWarnings(value="DL_SYNCHRONIZATION_ON_BOXED_PRIMITIVE")
    final static Long expiringLock = new Long(System.currentTimeMillis() + 10);

    public static void main(String[] args) {
        while (increment(expiringLock)) {
            System.out.println(counter);
        }
    }

    // The following SuppressWarnings prevents the FindBugs warning
    @edu.umd.cs.findbugs.annotations.SuppressWarnings(value="DL_SYNCHRONIZATION_ON_BOXED_PRIMITIVE")
    protected static boolean increment(Long expiringLock)
    {
        synchronized (expiringLock) { // <<< FindBugs warning is here: Synchronization on Long in SyncOnBoxed.increment()
            counter++;
        }
        return …
