有一个简单的Mongo DB Producer连接到Mongo数据库
@SuppressWarnings({ "deprecation", "resource" })
@ApplicationScoped
public class MongoDBProducer {
@Resource(name = "mongoUri")
private MongoClientURI mongoClientURI;
private DB database;
@PostConstruct
public void init() throws UnknownHostException {
MongoClient mongoClient = new MongoClient(mongoClientURI);
database = mongoClient.getDB(mongoClientURI.getDatabase());
}
@Produces
public DB createDB() {
return database;
}
}
我的src / main / resources / META-INF中的资源文件
<resources>
<Resource id="mongoUri" class-name="com.mongodb.MongoClientURI" constructor="uri">
uri mongodb://localhost/ironman
</Resource>
</resources>
还有一个简单的Junit @RunWith（WeldJUnit4Runner.class）
public class MongoDBProducerTest {
@Inject
DB mongoDb;
@Test
public void runSampleTest() {
assertEquals(mongoDb.collectionExists("jobs"), true);
}
}
收到以下错误：org.jboss.weld.exceptions.WeldException：WELD-000049：无法调用public void test.dingo.query.db.util.MongoDBProducer.init（）在test.dingo上抛出java.net.UnknownHostException . query.db.util.MongoDBProducer@a1cdc6d
使用Weld
<dependency>
<groupId>org.jboss.weld.se</groupId>
<artifactId>weld-se</artifactId>
<version>2.2.8.Final</version>
</dependency>
WeldContext和WeldJUnit4Runner来自这里 - http://memorynotfound.com/java-se-unit-testing-cdi-junit-jboss-weld-se/

如果你想在单元测试中处理@Resource，你可以查看ejb-cdi-unit它在Weld-SE中运行测试并提供一个CDI-Extension，用@Inject替换@Resource，这样你就可以在你的测试中定义一个CDI-Alternative to被注射
