测试方法：

 1     @Test
 2     public void testAdd(){
 3         logger.debug("testAdd !===================");
 4 
 5         try {
 6             ApplicationContext ctx=new 
 7                     ClassPathXmlApplicationContext("applicationContext.xml");
 8             UserService    userService=(UserService)ctx.getBean("userService");
 9             User user = new User();
10             user.setUserCode("test001");
11             user.setUserName("测试用户001");
12             user.setUserPassword("1234567");
13             Date birthday = new SimpleDateFormat("yyyy-MM-dd").parse("1984-12-12");
14             user.setBirthday(birthday);
15             user.setCreationDate(new Date());
16             user.setAddress("地址测试");
17             user.setGender(1);
18             user.setPhone("13688783697");
19             user.setUserRole(1);
20             user.setCreatedBy(1);
21             user.setCreationDate(new Date());
22             boolean flag = userService.addNewUser(user);
23             logger.info("添加用户的结果："+flag);
24
