java - 使用 SolrServer 时 Bean 未注入(inject) CDI 和 Arquillian 测试失败

Question

我的 Arquillian 测试如下所示:

    import static org.junit.Assert.assertNotNull;
    import static org.junit.Assert.assertTrue;      
    import javax.enterprise.inject.spi.CDI;
    import javax.inject.Inject;     
    import org.jboss.arquillian.junit.Arquillian;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.wildfly.swarm.arquillian.DefaultDeployment;

    @RunWith(Arquillian.class)
    @DefaultDeployment(type = Type.WAR)
    public class CDIArquillianTest {

        @Inject
        private SomeClass someclass;

        @Test
        public void testInjection() {
            assertNotNull(someclass);
            assertTrue(someclass.printI().contains("my string"));
        }

        @Test
        public void testCDIContainerPresence() throws Exception {
            assertNotNull(CDI.current());
        }
    }

注入(inject)类:

    import javax.enterprise.context.ApplicationScoped;
    import org.apache.solr.client.solrj.SolrServer;

    @ApplicationScoped
    public class SomeClass{ 
        private SolrServer solrServer;

        public SomeClass(){     
        }

        public String printI(){
            String somestr = "my string";
            return somestr;
        }       
    }

在它的内部，有一个 SolrServer 类，这就是问题所在。没有类包含，一切正常。错误消息告诉我 SomeClass 被忽略了，因为找不到 SolrServer 类。我该如何处理这个错误？我应该手动包含这个 SolrServer 类吗？不能在这里使用@DefaultDeployment？也许 SolrServer 在某种程度上与 CDI 不兼容？

在 Ken 的回答后，我将 @DefaultDeployment(type = Type.WAR) 添加到 arquilian 测试中，现在该测试的部署工作正常，但测试失败并显示以下消息(没有 SolrServer 一直正常工作):

Answer 1

问题似乎是正在创建的部署是 JAR 而不是 WAR，这就是 solr 库不存在的原因。

您将需要使用:

@DefaultDeployment(type = WAR)

不仅仅是

@DefaultDeployment
