java - 数组索引越界 : index0

Question

我有以下代码:

public interface CustomPlanRepository {
    void plansUpdate(Query query,Update update,Class classname,String Collection);  
}

@Repository
public interface PlanRepository extends MongoRepository<Plan, 
                                          Serializable>,CustomPlanRepository{

    Plan findById(String id);
}

它在服务器启动期间抛出以下异常:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'planManagementController': Unsatisfied dependency expressed through field 'planService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'planServiceImpl': Unsatisfied dependency expressed through field 'planRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'planRepository': Invocation of init method failed; nested exception is java.lang.IndexOutOfBoundsException: Index: 0

如果我删除它:

void plansUpdate(Query query,Update update,Class classname,String Collection);

服务器加载非常好。

如何解决这个问题？

当您组合 MongoRepository 和 customRepository (CustomPlanRepository) 时，您必须实现 CustomRepository 接口(interface) (CustomPlanRepositoryImpl)。 Spring 无法创建此实现。

public class CustomPlanRepositoryImpl implements CustomPlanRepository {
    @Autowired
    private MongoTemplate mongoTemplate;

     void plansUpdate(Query query,Update update,Class classname,String Collection){
    ....

     }
