使用ssh整合时出现的异常

使用ssh整合时出现的错误
在使用接口测试的时候出现

Exception in thread "main" java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Boolean
at com.sun.proxy.$Proxy5.doDraw(Unknown Source)
at com.accp.service.impl.UserinfoServiceImpl.main(UserinfoServiceImpl.java:45)

用这段代码可以通过测试

public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
UserinfoDao dao = (UserinfoDao) context.getBean("userinfoDao");
Userinfo userinfo = dao.findByBankNo(new BigDecimal("2222222222222222222"));
userinfo.setBalance(userinfo.getBalance()-100);
System.out.println(dao.doDraw(userinfo));
}

但是换成这段代码就不能通过测试了

public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");
UserinfoService service = (UserinfoService) context.getBean("userinfoService");
Userinfo userinfo = service.findByBankNo(new BigDecimal("2222222222222222222"));
userinfo.setBalance(userinfo.getBalance()-100);
System.out.println(service.doDraw(userinfo));
}

Spring的配置文件beans.xml的代码

[解决办法]
你打断点追一下，在dao实现doDraw方法里面 和service实现里面  看看走到哪里报的错。
