分布式鎖 分段鎖 基於 memcached redis zookeeper (3種資源模式) 實現

Example

//對 segmentation_object 這個字串加鎖ObjectLock objectSegmentationLock = new ObjectLock("segmentation_object");try {    objectSegmentationLock.lock();    dosomething();} catch (Exception e) {    e.printStackTrace();} finally {    objectSegmentationLock.releaseLock();}try {    //嘗試加鎖直到5秒後逾時加鎖失敗    if(objectSegmentationLock.tryLock(5000)) {        dosomething();    }} catch (Exception e) {    e.printStackTrace();} finally {    objectSegmentationLock.releaseLock();}CodeLock codeLock = new CodeLock();try {    //直接對以下代碼（dosomething）進行阻塞加鎖直到獲得鎖    codeLock.lock();    dosomething();} catch (Exception e) {    e.printStackTrace();} finally {    codeLock.releaseLock();}try {    //直接對以下代碼（dosomething）嘗試加鎖 直到5秒後逾時加鎖失敗    if(codeLock.tryLock(5000)) {        dosomething();    }} catch (Exception e) {    e.printStackTrace();} finally {    codeLock.releaseLock();}
