测试Spring MVC API：未找到合格bean

Question

我有以下由Spring MVC API提供的具有单endpointgetAnnotation的结构：

@SpringBootApplication
public class Application {
    @Bean
    public javax.validation.Validator localValidatorFactoryBean() {
        return new LocalValidatorFactoryBean();
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}


@Service
public class MyAnalyzerImpl implements MyAnalyzer
{

    @Autowired
    public MyAnalyzerImpl() {}

    @Override
    public Annotations getAnnotation(MyRequest request)
    {
        // ...
    }
}

接口

public interface MyAnalyzer {
    Annotations getAnnotation(MyRequest request);
}

控制器

@RestController
@RequestMapping("/thisapi/{id}")
public class MyController {

    @Autowired
    @Qualifier("MyAnalysis")
    MyAnalyzer myAnalyzer;

    @RequestMapping(value = "/getAnnotation", method = RequestMethod.GET)
    public Annotations getAnnotation(@PathVariable String docId,
                                     @RequestParam(value = "document", defaultValue = "{'id':'1','title':'bla-bla'}") String text) {
        MysRequest myRequest = new MyRequest(MyRequest.TYPE_ANNOTATION, text);
        return myAnalyzer.getAnnotation(myRequest);
    }
}

为了测试API，我首先创建了src/test/java/myAnalyzerImplTest.java，并且能够成功地执行它：

@RunWith(SpringJUnit4ClassRunner.class)
public class MyAnalyzerImplTest {

    private MyAnalyzerImpl myAnalyzer;
    private String sampleText;

    @Test
    public void testEndpoint() throws Exception {
        MyRequest request = new MyRequest(  MyRequest.TYPE_ANNOTATION,
                                                    "1",
                                                    sampleText
                                                 );
        Annotations results = myAnalyzer.getAnnotation(request);
        Assert.assertTrue("This " + results.getPayload().getWords().size() + ") " +
                "should be greater than 0", results.getPayload().getWords().size() > 0);
    }

    @Before
    public void setUp() throws Exception {
        myAnalyzer = new MyAnalyzerImpl();
        File f = new File("src/test/resources/texsts/text.json");
        if (f.exists()){
            InputStream is = new FileInputStream("src/test/resources/texts/text.json");
            samplePublication = IOUtils.toString(is);
        }
        Thread.sleep(1000);
    }

}

Answer 1

正如注释中所讨论的，最初的错误是由于使用了无效的限定符@qualifier（“myanalysis”）。上下文中没有id“myanalysis”的bean。因为只有一个合适的实现，所以使用其他@qualifier是没有用的。

第二个错误是由于在构造函数中无效地使用了@autowired。这里描述了一个类似的问题
