Question

我想添加一个新的存储库方法，以检索元素列表。

主要问题是：

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

我有点努力，它无法自动装载 InsulinGTServiceImpl 中的存储库，如果您按照错误，最终会进入 InsulinGTRepository 你可以看到的错误。

InsulinGTServiceImpl

    @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);
    }



}

InsulinGTService

public interface InsulinGTService {

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

}

在 InsulinGTRepository 中说，无效的派生查询！找不到类型为InsulinGT的物业storelistfromcontainer！

public interface InsulinGTRepository extends CrudRepository<InsulinGT, Long> {


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

InsulinGT

@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alredy尝试重命名这些课程，但没有任何帮助。没有新添加方法的旧版本正常工作没有任何问题。感谢每一位帮助。

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

您需要在单独的界面中定义自定义方法。

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

现在定义一个基本接口

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

还提供满足CustomRepo的bean：

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

注意名称CustomRepoImpl是重要的（extension接口的默认bean查找策略是以Impl为后缀。
