java.sql.SQLException：沒有合適的驅動程序<tx：annotation-driven />

我正在創建一個使用hibernate 4.1.4，struts 2.1和spring 3.1.1的web項目，而且我正面臨一個問題。我不知道爲什麼會出現這種情況：當我使用它讓我看到這樣的一個錯誤：java.sql.SQLException：沒有合適的驅動程序<tx：annotation-driven />

，並沒有通過我的春天層，如服務去了，但是當我刪除此從我的applicationContext.xml的代碼行，它會經過服務，然後道，但我不能創造任何會話： HibernateException的無會話發現當前線程，我的applicationContext.xml：

，也許它是有用的，當我調試我的項目也將通過這一行動

public String execute() { 
    if(firstName.equals("") || lastName.equals("")){ 
     return ERROR; 
    } 

    ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml"); 
    Students student = new Students(); 
    student.setFirstName(firstName); 
    student.setLastName(lastName); 
    StudentService service = (StudentService) ctx.getBean("StudentService"); 
    service.addStudent(student); 
    return SUCCESS; 
}

，當我使用TX：它要打開類JdkDynamicAopProxy註解，它不能，但是當我做不使用tx：annotations，它將轉到StudentServiceImpl.addStudent（學生）！

我很困惑，這是我第一個使用j2ee的項目，我應該在明天早上發佈：|，所以任何建議將不勝感激。

您需要在數據源bean中定義'driverClass'屬性。 – 2014-09-03 12:40:33

你能多解釋一下嗎？我怎樣才能做到這一點？ – 2014-09-03 12:41:48

與設置網址，用戶名和密碼的方式相同。 – 2014-09-03 12:44:16

你的數據源豆應該像下面

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> 
     <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> 
     <property name="url" value="jdbc:mysql://localhost:3306/enrollment"></property> 
     <property name="username" value="root"></property> 
     <property name="password" value="root"></property> 
    </bean>

注意你缺少的基礎數據源driverClassName屬性。
