spring 引导应用程序中的 Hazelcast 客户端测试
Hazelcast client testing in spring boot application
我们有一个 spring 启动应用 运行 hazelcast-client 3.12.6。
hazelcast 服务器不是嵌入式的，我们 运行 在外部连接它并与 hazelcast 客户端连接。
问题是当 spring 启动测试正在 运行 嵌入 tomcat 启动时失败，因为没有集群 运行 使客户端无法连接。
下面是测试 class 代码。
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
public class ApplicationStartTest {
@Test
void contextLoads() {
}
}
我们正在使用下面提到的 beans 配置我们的 hazlecast 客户端
@Bean
public ClientConfig hazelcastConfig() {
ClientConfig config = new ClientConfig();
String[] addresses = hazelCastEndPoints.split(",");
ClientNetworkConfig networkConfig = config.getNetworkConfig();
networkConfig.addAddress(addresses);
networkConfig.setSmartRouting(false);
networkConfig.setRedoOperation(true);
networkConfig.setConnectionTimeout(30000);
Timestamp timestamp = new Timestamp(System.currentTimeMillis());
config.setInstanceName(applicationName + timestamp.toString());
// HazelcastClient.newHazelcastClient(config);
return config;
}
@Bean
public HazelcastInstance hazelcastInstance(ClientConfig config) {
return HazelcastClient.newHazelcastClient(config);
}
运行宁测试时的错误日志：

如果你能告诉我如何运行我在这种情况下的测试，那将非常有帮助。
如果你只想要一个简单的单元测试，那么你可以随时模拟 HazeclastInstance。
但是，如果您想创建一个集成（或端到端）测试，那么您应该先启动 Hazelcast 服务器，然后 Hazelcast 客户端才能连接到它。这是一个例子 how to do it using @SpringBootTest
我们有一个 spring 启动应用 运行 hazelcast-client 3.12.6。 hazelcast 服务器不是嵌入式的，我们 运行 在外部连接它并与 hazelcast 客户端连接。
