Java Spring異常：未找到類型xxx的屬性xxx

Question

我想添加一個新的存儲庫方法，以檢索元素列表。

主要問題是：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'insulinGTService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private xxx.xxx.xxx.repository.InsulinGTRepository xxx.xxx.xxx.service.jpa.InsulinGTServiceImpl.repository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'insulinGTRepository': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: No property storelistfromcontainer found for type class xxx.xxx.xxx.domain.InsulinGT

我有點解決了，它無法自動連接InsulinGTServiceImpl中的存儲庫 ，如果您遵循此錯誤，則最終會出現在InsulinGTRepository中 ，並看到錯誤。

胰島素GTServiceImpl

    @Service("insulinGTService")
    @Repository
    @Transactional
    public class InsulinGTServiceImpl implements InsulinGTService {

    @Autowired
    private InsulinGTRepository repository;

    @Override
    @Transactional(readOnly = true)
    public List<InsulinGT> findByID(Long insulinid) {
        // TODO Auto-generated method stub
        return Lists.newArrayList(repository.findByUserid(insulinid));
    }

    @Override
    public InsulinGT save(InsulinGT insulin) {
        return repository.save(insulin);
    }



    @Override
    public List<InsulinGT> liststorelistfromcontainerSave(InsulinlistGT insulin) {
        // TODO Auto-generated method stub
        return repository.storelistfromcontainer(insulin);
    }



}

胰島素GT服務

public interface InsulinGTService {

    public List<InsulinGT> findByID(Long insulinid);
    public InsulinGT save(InsulinGT insulin);
    public List<InsulinGT> storelistfromcontainerSave(InsulinlistGT insulin);

}

在InsulinGTRepository春天說， 無效的派生查詢！ 找不到InsulinGT類型的來自容器的屬性storelist！

public interface InsulinGTRepository extends CrudRepository<InsulinGT, Long> {


    public List<InsulinGT> findByUserid (Long id);
    public List<InsulinGT> storelistfromcontainer(InsulinlistGT insulin);
}

胰島素GT

@Entity
@Table(name = "insulin")
public class InsulinGT implements Serializable {                    
        private static final long serialVersionUID = 3333976984277807655L;
        private Long insulinid;
        private Long userid;
        private String ivalue;
        private String therapie;
        private String insulinname;
        private String einheit;
        private Date date;
        private Date time;

        @Id
        @GeneratedValue(strategy = IDENTITY)
        @Column(name = "insulin_id")
        public Long getInsulinid() {
            return insulinid;
        }

        public void setInsulinid(Long insulinid) {
            this.insulinid = insulinid;
        }

        @Column(name = "users_id")
        public Long getUserid() {
            return userid;
        }

        public void setUserid(Long userid) {
            this.userid = userid;
        }

        @NotNull    
        @Column(name = "ivalue")
        public String getIvalue() {
            return ivalue;
        }

        public void setIvalue(String ivalue) {
            this.ivalue = ivalue;
        }


        @Column(name = "date")
        public Date getDate() {
            return date;
        }

        public void setDate(Date date) {
            this.date = date;
        }


        @Column(name = "time")
        public Date getTime() {
            return time;
        }

        public void setTime(Date time) {
            this.time = time;
        }

        @Column (name = "therapie")
        public String getTherapie() {
            return therapie;
        }


        public void setTherapie(String therapie) {
            this.therapie = therapie;
        }

        @Column(name = "insulinname")
        public String getInsulinname() {
            return insulinname;
        }

        public void setInsulinname(String insulinname) {
            this.insulinname = insulinname;
        }

        @Column(name = "einheit" )
        public String getEinheit() {
            return einheit;
        }

        public void setEinheit(String einheit) {
            this.einheit = einheit;
        }

}

我已經嘗試過重命名類，但是沒有任何幫助。 沒有新添加方法的舊版本可以正常工作，沒有任何問題。 感謝您的幫助。

參見http://docs.spring.io/spring-data/jpa/docs/1.5.0.RELEASE/reference/html/repositories.html#repositories.create-instances

您需要在單獨的界面中定義自定義方法。

public interface CustomRepo {
    public List<InsulinGT> storelistfromcontainer(InsulinlistGT insulin);
}

現在定義一個基本接口

public interface InsulinGTRepository extends CrudRepository<InsulinGT, Long>, CustomRepo {
    public List<InsulinGT> findByUserid (Long id);
}

還提供一個滿足CustomRepo的bean：

public class CustomRepoImpl implements CustomRepo {
    @Override
    public List<InsulinGT> storelistfromcontainer(InsulinlistGT insulin) {
        throw new UnsupportedOperation("TODO");
    }
}

注意，CustomRepoImpl的名稱很重要（ extension接口的默認bean查找策略是在Impl后綴。
