我的项目中存在问题，没有任何帮助.. 其他类不会显示，因为一切都很好，如何修复此错误？我在Intellij IDEA中编写，创建maven项目，加载spring和hibernate库，还加载mysql连接器和其他库。 我的主要课程：
import DAO.StoreDAO;
import logic.Store;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Main {
public static void main(String[] args){
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
new String[] { "applicationContext.xml" }, true);
StoreDAO studDao = (StoreDAO) context.getBean("dataDao");
Store data1 = new Store();
data1.setName("test1");
data1.setType("test1Type");
data1.setAddress("test1Address");
studDao.saveStore(data1);
System.out.println(studDao.findStore("t%").size());
}
}

还有很多其他......
答案 0 :(得分：0)
请确保一些事情
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
<property name="url">
<value>jdbc:mysql://localhost/practick</value>
</property>
<property name="username">
<value>root</value>
</property>
<property name="password">
<value></value>
</property>
</bean>
此错误基本上来自数据源或SessionFactory，并且它被链接到第一个资源bean。
txAdvice需要事务管理器，它需要sessionFactory
你的错误实际上是这一点，显示
WARNING: Exception encountered during context initialization - cancelling refresh attempt
添加以下内容并检查其是否有效
Spring支持通过以下方式自动扫描实体类：
<context:component-scan base-package="your.package.name" />
