自定义介体ClassNotFoundException TransactionSynchronization(Custom Mediator ClassNotFoundException TransactionSynchronization)

 我创建了一个自定义中介类，它使用spring jdbc来访问数据库中的数据。 
 我从该类创建一个jar并将其部署在WSO2_HOME / repository / components / lib中。 
 之后，我将以下jar添加到同一文件夹： 
 春天了jdbc.jar， 
 弹簧tx.jar。 

 但是，当我尝试自定义中介时，出现错误“ClassNotFoundException org \ springframework \ transaction \ support \ TransactionSynchronization”。 

 问题是我很确定spring-tx.jar中提供了“TransactionSynchronization”类。 任何人都可以帮我解决这个问题吗？ :) 

I make a custom mediator class that used spring jdbc to access data from database. 
I make a jar from that class and deploy it in WSO2_HOME/repository/components/lib.
 After that I add the following jar to the same folder : 
spring-jdbc.jar,
 spring-tx.jar. 

But when I tried the custom mediator there is an error "ClassNotFoundException org\springframework\transaction\support\TransactionSynchronization". 

The problem is I'm pretty sure that "TransactionSynchronization" class is available in the spring-tx.jar. Can anyone help me to solve this problem? :)
