示例

public class ClassA { public void makeStream (OutputStream oStream) { try { ZipOutputStream stream = new ZipOutputStream(oStream); stream.write(7); //do something... stream.close(); } catch (IOException e) { //stream leaked... } } }

解决方案

为了避免资源泄漏，请确保对每个 java.util.zip.ZipOutputStream 都调用 close()。 注意：此规则适用于所有形式的 ZipOutputStream 构造函数。

public class ClassA { public void makeStream (OutputStream oStream) { ZipOutputStream stream = null; try { stream = new ZipOutputStream(oStream); stream.write(7); //do something... } catch (IOException e) { //do something... } finally { if (stream != null) { try { stream.close(); } catch(IOException e) { //do something... } } } } }
