내가 여기서 무엇을 놓치고 있니?
해결법
-
==============================
1.이 포럼에는 해결책이 있습니다.

너무 중복됩니다.

2.내 환경 : 최대 절전 모드 5.2.5 + 봄 4.3.4
내 환경 : 최대 절전 모드 5.2.5 + 봄 4.3.4
이것이 내가이 문제를 겪은 이유입니다. hibernate.cfg.xml에 dabatabase 정보를 설정합니다 :
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/Elec</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password">123</property>이것이 내가이 문제를 해결 한 방법입니다. 나는 ID가 스프링 구성 XML 파일의 dataSource 인 빈을 만든 다음이 빈에서 데이터베이스 정보를 구성합니다. 그리고 id가 sessionFactory 인 bean에서 dataSource라는 속성으로 dataSource를 참조합니다.
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/Elec"/> <property name="username" value="root"/> <property name="password" value="123"/> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="configLocation" value="classpath:hibernate.cfg.xml"/> </bean> <bean id="txManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"></property> </bean>
