Question

我很难将Web套接字消息代理集成到我现有的spring项目中。我有一些功能齐全的存储库和服务。但是，当我尝试使用websocket配置（通过组件扫描从config.xml自动加载）连接我的东西时，我现有的所有测试都突然失败。

WebSocketConfig

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableStompBrokerRelay("/topic/");
        config.setApplicationDestinationPrefixes("/app");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/main");
    }


}

测试

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:config.xml"})
public class CategoryDaoTest extends DomainTestBase {

    @Autowired
    private CategoryDao categoryDao;

    @Test
    public void testAdd() {
        int size = categoryDao.list().size();
        categoryDao.add(new Category(5L, "test-category", "lorem ipsum"));
        assertTrue (size < categoryDao.list().size());
    }

    @Test
    public void testUpdate() {
        Category category = new Category(5L, "test-category", "lorem ipsum");
        categoryDao.add(category);
        category.setTitle("updated");
        categoryDao.update(category);

        // verify actual update
        Category found = categoryDao.find(category.getId());
        assertEquals("updated", found.getTitle());
    }

    @Test
    public void testFind() {
        Category category = new Category(5L, "test-category", "lorem ipsum");
        categoryDao.add(category);
        Category found = categoryDao.find(category.getId());
        assertEquals(found, category);
    }

}

Answer 1

您的类路径依赖性不一致。基于加载Spring时的堆栈跟踪，它无法找到ThreadPoolTaskScheduler.setRemoveOnCancelPolicy()方法。检查类路径上的jar，看看你是否有某个Spring jar的旧版本。很可能在类路径中有一个旧的Spring jar包含该类（没有方法），并且它首先被拾取。

这可能是因为jar通过传递依赖包含在内。如果您使用Maven，可以使用Spring BOM pom确保所有弹簧罐都是一致的。

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-framework-bom</artifactId>
            <version>4.1.3.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

如果使用gradle，您可以执行以下操作：

configurations.all {
  resolutionStrategy {

    // add a dependency resolve rule
    eachDependency { DependencyResolveDetails details ->
      //specifying a fixed version for all libraries with 'org.springframework' group
      if (details.requested.group == 'org.springframework') {
          details.useVersion'4.1.3.RELEASE'
      }
    }
  }
}

我在这里找到了一个解决方案，它对我有用。

您只需将这些依赖项添加到pom.xml中即可。

    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-core</artifactId>
        <version>8.0.8</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-websocket</artifactId>
        <version>8.0.8</version>
        <scope>test</scope>
    </dependency>
