当在使用 Apache Curator ZooKeeper 进行单元测试时出现错误时,可以尝试以下解决方法:
import org.apache.curator.test.TestingServer;
public class ZooKeeperTest {
private static TestingServer server;
@BeforeClass
public static void setUp() throws Exception {
server = new TestingServer(2181, true);
// 其他初始化操作
}
@AfterClass
public static void tearDown() throws Exception {
server.close();
}
// 单元测试方法
}
import org.apache.curator.framework.CuratorFramework;
import org.apache.curator.retry.ExponentialBackoffRetry;
public class ZooKeeperTest {
private static CuratorFramework client;
@BeforeClass
public static void setUp() throws Exception {
client = CuratorFrameworkFactory.newClient("localhost:2181", new ExponentialBackoffRetry(1000, 3));
client.start();
// 其他初始化操作
}
@AfterClass
public static void tearDown() throws Exception {
client.close();
}
// 单元测试方法
}
import org.apache.curator.framework.CuratorFramework;
import org.apache.curator.framework.recipes.locks.InterProcessMutex;
public class ZooKeeperTest {
private static CuratorFramework client;
@BeforeClass
public static void setUp() throws Exception {
client = CuratorFrameworkFactory.newClient("localhost:2181", new ExponentialBackoffRetry(1000, 3));
client.start();
// 其他初始化操作
}
@AfterClass
public static void tearDown() throws Exception {
client.close();
}
@Test
public void testLock() throws Exception {
InterProcessMutex lock = new InterProcessMutex(client, "/test/lock");
lock.acquire();
// 执行测试逻辑
lock.release();
}
}
通过以上方法,可以解决 Apache Curator ZooKeeper 单元测试出现错误的问题。
