如何减少 java 线程本地的冗长冗余
How to reduce the verbose redundancy of java thread local
我有一个 class,我想声明一个私有成员,它是一个线程本地字典。这就是它的样子...
private static ThreadLocal<HashMap<Integer, Measurement>> measurements =
new ThreadLocal<HashMap<Integer, Measurement>>()
{
@Override protected HashMap<Integer, Measurement> initialValue()
{
return new HashMap<Integer, Measurement>();
}
};
如您所见,我必须键入 HashMap<Integer, Measurement>
多得离谱的次数。有没有办法让这个更简洁?
这个怎么样?
private static ThreadLocal<HashMap<Integer, Measurement>> measurements = ThreadLocal.withInitial(HashMap::new);
