Java EE 项目的依赖注入错误

【问题标题】：Dependency injection error on Java EE projectJava EE 项目的依赖注入错误
【发布时间】：2016-04-21 07:36:05
【问题描述】：

我正在开发一个 Java EE 7 Web 应用程序。我使用的技术：Maven、JPA 2.1、EJB 3.2、JSF 2.2、WildFly 10 Final。

EJB 注入提示错误

找到多个 EJB，其接口类型为“...InsuranceHouseDAO”，用于绑定...InsuranceHouseServiceBean/insuranceHouseDAO”。

这是InsuranceHouseDAO 类，它位于pm-domain Maven 模块中：

@Local
public interface InsuranceHouseDAO extends BaseDao<InsuranceHouse> {

}

这里是InsuranceHouseDAOBean 类，它实现了接口：

@Stateless
public class InsuranceHouseDAOBean extends BaseDAOBean<InsuranceHouse> implements InsuranceHouseDAO {

    public InsuranceHouseDAOBean() {
        super(InsuranceHouse.class);
    }

}

pm-services模块中的InsuranceHouseService接口如下：

@Local
public interface InsuranceHouseService {

    public void create(final InsuranceHouseTO insuranceHouseTO);
    public InsuranceHouseTO find(Long id);
    public void update(InsuranceHouseTO insuranceHouseTO);
    public void delete(InsuranceHouseTO insuranceHouseTO);
    public List<InsuranceHouseTO> findAll() throws Exception;
    public void deleteAll();
    public boolean exists(Long id);
    public Long count();

}

这是它的实现，InsuranceHouseServiceBean 类：

@Stateless
public class InsuranceHouseServiceBean implements InsuranceHouseService {

    @EJB
    private InsuranceHouseDAO insuranceHouseDAO;

    @EJB
    private InsuranceHouseAssembler insuranceHouseAssembler;

    public InsuranceHouseServiceBean() {
    }

    @Override
    public void create(InsuranceHouseTO insuranceHouseTO) {
        InsuranceHouse insuranceHouse = insuranceHouseAssembler.dtoToModel(insuranceHouseTO);
        insuranceHouseDAO.create(insuranceHouse);
    }

    @Override
    public List<InsuranceHouseTO> findAll() throws Exception {
        List<InsuranceHouseTO> dtoList = new LinkedList<>();
        List<InsuranceHouse> insuranceHouseList;
        try {
            insuranceHouseList = insuranceHouseDAO.findAll();
            if(insuranceHouseList != null){
                for (InsuranceHouse insuranceHouse : insuranceHouseList) {
                    dtoList.add(insuranceHouseAssembler.modelToDto(insuranceHouse));
                }
            }
        } catch (Exception e) {
            // OK, the exception handling isn't perfect yet...
            e.printStackTrace();
        }

        return dtoList;
    }

    // +other methods, which I haven't implemented yet

}

这是堆栈跟踪：

我也尝试过使用@Inject 注释而不是@EJB，但在这种情况下有一个有趣的行为：编译成功，但每隔一次部署就会出现异常。

当我尝试打开从InsuranceHouseServiceBean 类调用findAll() 方法的某个页面时，出现以下错误：

无法将 ...InsuranceHouseService 字段设置为 ...InsuranceHouseService$2112160917$Proxy$_$$_Weld$EnterpriseProxy$。

它在每秒钟部署一次时运行良好。

我已将 beans.xml 放在 META-INF 和 WEB-INF 文件夹中。

这是我的支持 bean，我在这里调用服务 bean 的 findAll() 方法：

@Named
@RequestScoped
public class InsuranceHouseController {

    @Inject
    private InsuranceHouseService insuranceHouseService;

    private InsuranceHouseTO insuranceHouseTO;

    @Inject
    private NavigationController navigationController;

    private List<InsuranceHouseTO> insuranceHouses;

    @PostConstruct
    public void init(){
        insuranceHouseTO = new InsuranceHouseTO();
        insuranceHouses = new ArrayList<InsuranceHouseTO>();

        try {
            insuranceHouses = insuranceHouseService.findAll();
        } catch (Exception e) {
            // TODO: make exception handling...
            e.printStackTrace();
        }
    }

    public InsuranceHouseTO getInsuranceHouseTO() {
        return insuranceHouseTO;
    }

    public void setInsuranceHouseTO(InsuranceHouseTO insuranceHouseTO) {
        this.insuranceHouseTO = insuranceHouseTO;
    }

    public List<InsuranceHouseTO> getInsuranceHouses() {
        return insuranceHouses;
    }

    public void setInsuranceHouses(List<InsuranceHouseTO> insuranceHouses) {
        this.insuranceHouses = insuranceHouses;
    }

    public void registerInsuranceHouse(){
        insuranceHouseService.create(insuranceHouseTO);
        navigationController.moveToAdminCreateInsuranceHouse();
    }

}

还有堆栈跟踪，属于这个错误：

我只包含了 pom 的相关部分，主要是模块的依赖关系。

【问题讨论】：

  • 从第一个错误看来，InsuranceHouseDAOBean 包含在 pm-web-0.0.1-SNAPSHOT.war 和 pm-domain-0.0.1-SNAPSHOT.jar 中。您可能应该检查您的构建以确保它仅包含在一个点中。有可能您声明了从战争到 jar 的依赖关系，并且 jar 除了包含在 ear 中之外，还包含在 war 中。
  • 是的，我已经检查过了，这是真的：pm-web-0.0.1-SNAPSHOT.war 和 pm-domain-0.0.1-SNAPSHOT.jar 还包含 InsuranceHouseDAOBean。但是我有点困惑，具体模块中的依赖关系应该如何声明呢？我有一个父 (pm)、pm-domain、pm-services、pm-web、pm-common（由 pm-domain、pm-services 和 pm-web 使用）和 pm-ear。
  • 我不是 Maven 专家，但是，在 WAR 的 POM 中尝试将对 JAR 的依赖声明为 &lt;scope&gt;provided&lt;/scope&gt;。
  • 我试过这个，但没有帮助。
  • @andris11m，您能否用每个模块的 pom.xml 文件的 relevant 部分更新您的问题？另外，请确认您的项目中没有重复的 bean...

【解决方案1】：

我阅读了所有 cmets，我认为 @Nikos Paraskevopoulos 为您指明了正确的方向。

请注意，ejb 模块“pm-services”、“pm-domain”和“pm-common”包含在文件根目录的ear 文件patient-manager.ear 中.

另外，“pm-services”和“pm-common”是“pm-web”的编译依赖，将包含在pm-web.war/WEB-INF/lib/中

因此，在编译时没有错误，但在运行时 InsuranceHouseDAO 的 两个实例，加载了一个：

  • 一个由 ejb pm-domain-0.0.1-SNAPSHOT.jar 位于 "patient-manager.ear"."pm-domain-0.0.1-SNAPSHOT.jar" 李>
  • 另一个由 "patient-manager.ear"."pm-web-0.0.1-SNAPSHOT.war"\WEB-INF\lib\pm-domain-0.0.1-SNAPSHOT.jar

如您所见，第一个日志在这方面是不言自明的。

所以解决方案是声明 pm-web pom.xml 的依赖项“pm-services”和“pm-common”：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </parent>
    <artifactId>pm-web</artifactId>
    <packaging>war</packaging>

            <groupId>edu.sapientia.patientmanager</groupId>
            <artifactId>pm-common</artifactId>
            <version>0.0.1-SNAPSHOT</version>
            <scope>provided</scope>
        </dependency>
    </dependencies>
</project>
