    }
}
测试类
ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
        BeanDao dao = (BeanDao) ctx.getBean("userDAO");
        Users u = new Users();
        u.setId(22);
        u.setUsername("tx");
        dao.addBean(u);我现在程序执行到
this.getSqlMapClientTemplate()都没事，一调this.getSqlMapClientTemplate().insert("Users.insert", u);
就出错
java.lang.NoSuchMethodError: com.ibatis.sqlmap.client.SqlMapSession.getCurrentConnection()Ljava/sql/Connection;
