jakarta-ee - Arquillian 不能@Inject Stateless bean

Question

我使用 Arquillian 1.1.8 进行了集成测试，我使用 Wildfly 8.2.1 作为容器。这是测试:

@RunWith(Arquillian.class)
public class FileReaderAndWriterTest {

    private final MockDataFactory dataFactory = new MockDataFactory();

    @Rule
    public TemporaryFolder folder = new TemporaryFolder();

    @Inject
    private CSVFileWriter csvFileWriter;

    @Deployment
    public static WebArchive createDeployment() {
        MavenResolverSystem mavenResolverSystem = Maven.resolver();
        WebArchive archive = ShrinkWrap.create(WebArchive.class);
        archive.addClasses(FileReader.class, FileWriteService.class, MockDataFactory.class, CSVFileReader.class, 
                ExcelFileReader.class, CSVFileWriter.class, ConfigurationService.class, DataSet.class, Tuple.class, CSVFileWriter.CostCenterFilenameFilter.class);
        archive.addAsLibraries(mavenResolverSystem.loadPomFromFile("pom.xml").resolve("com.opencsv:opencsv").withTransitivity().asFile());
        archive.addAsLibraries(mavenResolverSystem.loadPomFromFile("pom.xml").resolve("org.apache.poi:poi").withTransitivity().asFile());
        archive.addAsLibraries(mavenResolverSystem.loadPomFromFile("pom.xml").resolve("org.apache.poi:poi-ooxml").withTransitivity().asFile());
        archive.addAsResource("config.properties").addAsResource("master_fte.csv").addAsManifestResource(EmptyAsset.INSTANCE, "beans.xml");
        System.out.println("yooooooooo" + archive.toString(true));
        return archive;
    }



    @Test
    public void csvReaderShouldProcessFileCorrectly() throws IOException{

    }
}

运行时，我得到这个异常:

我有一个类似的测试，包括一个有效的注入(inject)，所以这不是一般问题。

编辑:以下是 CSVFileWriter 的导入:

import com.xxx.xxx.configuration.ConfigurationService;
import com.xxx.xxx.datamodel.DataSet;
import com.opencsv.CSVWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.FilenameFilter;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.nio.file.attribute.PosixFilePermission;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.HashSet;
import java.util.List;
import javax.ejb.Stateless;
import javax.inject.Inject;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

Answer 1

错误在于，CSVFileWriter 正在实现一个接口(interface) FileWriteService。当我注入(inject) FileWriteService 时一切正常 >.>由于 CSVFileWriter 是迄今为止唯一实现它的一个，所以现在还可以，但我会将其更改为 JNDI 查找，以便更多实现。
