spring JdbcDao Support 를 사용 하여'dataSource'또는'jdbcTemplate'가 필요 합 니 다.

프로젝트 요구 에 따라 J2SE 통합 spring 을 사용 하여 JDBCtemplate 를 사용 하여 Dao 작업 을 할 때 다음 과 같은 이상 이 발생 합 니 다.

오류 가 발생 한 후 첫 번 째 느낌 은 설정 에 문제 가 없 을 것 입 니 다.기본 클래스 는 dataSource 주입 설정 을 했 고 자 료 를 찾 아 도 결과 가 없 었 습 니 다.그 후에 testdao 에 도 dataSource 를 주입 하여 정상적으로 작 동 했 습 니 다.조사 자 료 를 통 해...
하위 클래스 Bean 에서 도 부모 클래스 속성 을 설정 해 야 하 며,부모 클래스 의 속성 값 을 수정 하거나 덮어 쓸 수 있 습 니 다.
변경 후 설정

<bean id="daoBase" class="hk.egame.frame.base.DaoBase">
   <property name="dataSource" ref="dataSource" />
</bean>
        
<bean id="testDao" class="hk.egame.test.imp.DaoImpl" parent="daoBase">
