Spring Web 套接字消息代理未通过测试

Question

I have difficulties integrating a web socket message broker into my existing spring project. I have a few fully functional repositories and services. However, when I try to wire up my stuff with a websocket configuration (which is automatically loaded from config.xml with a component scan), all my existing tests suddenly fail.

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");
    }


}

Test

@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

You have inconsistent dependencies on your classpath. Based on the stacktrace when Spring is loaded it can't find the ThreadPoolTaskScheduler.setRemoveOnCancelPolicy() method. Check the jars on your classpath and see if you have an old version of certain Spring jars. Most likely there is an old Spring jar that contains that class (without the method) on your classpath and it is being picked up first.

This could be because the jar is being included through a transitive dependency. If you are using Maven, you can make sure all of your spring jars are consistent by using the Spring BOM pom.

<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>

If using gradle you can do something like:

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'
      }
    }
  }
}

I found a solution here and it works for me.

You just need to add these dependencies into your pom.xml.

    <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>

对我有用的是添加最新的依赖项： https : //mvnrepository.com/artifact/org.springframework/spring-websocket/5.2.4.RELEASE
