最近在使用spring data jpa的过程由于粗心的原因中遇到了一个异常，异常如下：

spring data jpa中的Repository如下：

@CacheConfig(cacheNames = "urls")@Repositorypublic interface SonarUrlRepository extends JpaRepository<SonarUrl, Long> {@CachePut(key = "#p0.id")@TransactionalSonarUrl saveUrl(SonarUrl sonarUrl);}

出现异常的原因是不认识saveUrl这个属性，原因如下：

1、JpaRepository中没有定义saveUrl这个方法2、该方法上面没有用@Query类似注解，如果@Query注解中的值为空，同样也会报这个异常
