Spring 使用 JdbcDaoSupport 无法注入 dataSource 或 jdbcTemplate

[weixin_40506575]

求助，
不继承 JdbcDaoSupport 可以使用，但一旦使用 JdbcDaoSupport 就报错

applicationContext.xml:

<context:property-placeholder location="classpath:db.properties"  />
<!-- 事务核心管理器,封装了所有事务操作. 依赖于连接池 -->
<bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" >
	<property name="jdbcUrl" value="${jdbc.jdbcUrl}" ></property>
	<property name="driverClass" value="${jdbc.driverClass}" ></property>
	<property name="user" value="${jdbc.user}" ></property>
	<property name="password" value="${jdbc.password}" ></property>
</bean>
   <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
       	<property name="dataSource" ref="dataSource" ></property>
    </bean>
<!-- <bean name="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >
	<property name="dataSource" ref="dataSource" ></property>
</bean>
<bean name="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate" >
	<property name="transactionManager" ref="transactionManager" ></property>
</bean> -->
<bean name="springTXTest" class="Spring.SpringTXTest" >
	<property name="dataSource" ref="dataSource" ></property>
</bean>

<!-- 开启使用注解管理aop事务 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
<!-- 1.将连接池 -->

<context:component-scan base-package="Spring"></context:component-scan>
<!-- <aop:aspectj-autoproxy></aop:aspectj-autoproxy> -->
</beans>

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext.xml")
public class SpringTXTest extends JdbcDaoSupport {
	

	@Test
	public void execute() {

		System.out.println("SpringTXTest before");
		System.out.println();
		String sql = "insert into bank values(?,?,?) ";
		this.getJdbcTemplate().update(sql,"1","lee",100);
		
	}

}
