错误背景：

基于ssh框架的javaweb项目

错误代码

package cn.com.service;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import com.opensymphony.xwork2.ActionSupport;
@Repository(value="regedit")
@Scope("prototype")
public class Regedit extends ActionSupport{
private String name;
public void setName(String name) {
	this.name = name;
}
public String getName() {
	return name;
}
@Transactional
public String regedit_user(){
	System.out.println("name:"+name);
	return "regedit_success";
}

	
}

 解决方案：

1、

注解版本：

<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>

配置版本：

<tx:annotation-driven transaction-manager="transactionManager" proxy-target-class="true"/>
<aop:config proxy-target-class="true">
<cache:annotation-driven proxy-target-class="true"/>

2、去掉@Transactional或者去掉extends ActionSupport

---

错误原因

@Transactional就是有spring管理，spring管理的对象要生成代理！

proxy-target-class="true"是基于类的管理

proxy-target-class="false"是基于接口的管理  默认是基于接口的管理！

基于接口的管理是抽象类，抽象类不可以生成代理
