spring 引导应用程序中的 Hazelcast 客户端测试

[英]Hazelcast client testing in spring boot application

 原文  2020-07-22 20:00:39  9   1    java/ spring-boot/ hazelcast

问题描述

we have a springboot app running with hazelcast-client 3.12.6.我们有一个运行 hazelcast-client 3.12.6 的 springboot 应用程序。 the hazelcast server is not embedded we are running that externally and connecting with the hazelcast client. hazelcast 服务器不是嵌入式的，我们在外部运行它并与 hazelcast 客户端连接。

The problem is when spring boot tests are running the embedded tomcat startup if failing because there is no cluster running so the client is unable to connect.问题是当 spring 启动测试正在运行嵌入式 tomcat 启动时，如果由于没有集群运行，因此客户端无法连接而失败。

Below is the Test class code.下面是测试 class 代码。

@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
public class ApplicationStartTest {

  @Test
  void contextLoads() {
  }
}

we are configuring our hazlecast client with below mentioned beans我们正在使用下面提到的 bean 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);
  }

it would be very helpful if you can point me how to run my test in this scenario.如果您能指出如何在这种情况下运行我的测试，那将非常有帮助。

If you want just a simple unit test, then you can always mock HazeclastInstance .如果您只想要一个简单的单元测试，那么您可以随时模拟HazeclastInstance 。

However, if you want to create an integration (or E2E) test, then you should start Hazelcast server first and then Hazelcast Client can connect to it.但是，如果要创建集成（或 E2E）测试，则应先启动 Hazelcast 服务器，然后 Hazelcast 客户端才能连接到它。 Here is an example how to do it using @SpringBootTest这是一个如何使用@SpringBootTest的示例
