以下 Spring 切入点有什么问题？

Question

我有一个切入点，用于建议在名为 Repository 的接口内声明的方法。但在运行时间内，该方面未应用。我的切入点有什么问题？

这里是切入点：-

@Around("execution (* *..Repository+.save*(..))" + " && args(entity,..) && target(target)")
    public Object cacheEvictOnSaveSingle(ProceedingJoinPoint proceedingJoinPoint, Region entity,
            RegionRepositoryCassandraImpl target) {
}

存储库界面如下：-

public interface Repository<ENTITY extends Entity<IDENTITY>, IDENTITY extends Serializable, DATAOBJECT> {

    /**
     * Find.
     *
     * @param id the id
     * @return the t
     */
    public ENTITY find(IDENTITY id);

    /**
     * Save.
     *
     * @param entity the entity
     */
    public void save(ENTITY entity);

    /**
     * Save async.
     *
     * @param entity the entity
     * @return the result set future
     */
    public ResultSetFuture saveAsync(ENTITY entity);

    /**
     * Save.
     *
     * @param entity the entity
     * @param batchStatement the batch statement
     */
    public void save(ENTITY entity, BatchStatement batchStatement);

    /**
     * Save.
     *
     * @param entities the entities
     */
    public void save(List<ENTITY> entities);

    /**
     * Save async.
     *
     * @param entities the entities
     * @return the result set future
     */
    public ResultSetFuture saveAsync(List<ENTITY> entities);

    /**
     * Save.
     *
     * @param entities the entities
     * @param batchStatement the batch statement
     */
    public void save(List<ENTITY> entities, BatchStatement batchStatement);

    /**
     * Delete.
     *
     * @param id the id
     */
    public void delete(IDENTITY id);

    /**
     * Delete async.
     *
     * @param id the id
     * @return the result set future
     */
    public ResultSetFuture deleteAsync(IDENTITY id);

    /**
     * Delete.
     *
     * @param id the id
     * @param batchStatement the batch statement
     */
    public void delete(IDENTITY id, BatchStatement batchStatement);

    /**
     * Delete.
     *
     * @param ids the ids
     */
    public void delete(List<IDENTITY> ids);

    /**
     * Delete async.
     *
     * @param ids the ids
     * @return the result set future
     */
    public ResultSetFuture deleteAsync(List<IDENTITY> ids);

    /**
     * Delete.
     *
     * @param ids the ids
     * @param batchStatement the batch statement
     */
    public void delete(List<IDENTITY> ids, BatchStatement batchStatement);

}

这是在抽象 class 中实现的：-

@Override
    public void save(ENTITY entity) {
        BatchStatement batchStatement = new BatchStatement();
        addEntityToSaveBatch(batchStatement, entity);

        session.execute(batchStatement);
    }

    /* (non-Javadoc)
     * @see com.byteobject.cloudsanthe.dbclient.repository.Repository#saveAsync(com.byteobject.cloudsanthe.dbclient.dto.compute.Entity)
     */
    @Override
    public ResultSetFuture saveAsync(ENTITY entity) {
        BatchStatement batchStatement = new BatchStatement();
        addEntityToSaveBatch(batchStatement, entity);

        return session.executeAsync(batchStatement);
    }

    /* (non-Javadoc)
     * @see com.byteobject.cloudsanthe.dbclient.repository.Repository#save(com.byteobject.cloudsanthe.dbclient.dto.compute.Entity, com.datastax.driver.core.BatchStatement)
     */
    @Override
    public void save(ENTITY entity, BatchStatement batchStatement) {
        addEntityToSaveBatch(batchStatement, entity);
    }

你能帮我解决这个问题吗？

方法签名有误，应该是:-

@Around("execution (* *..Repository+.save*(..))" + " && args(entity,..) && target(target)")
public Object cacheEvictOnSaveSingle(
    ProceedingJoinPoint proceedingJoinPoint,
    Entity<UUID> entity,
    RegionRepositoryCassandraImpl target
) {
    // ...
}

以下 Spring 切入点有什么问题？

Whats wrong with the following Spring PointCut?
