其实就是

public class UserResiterAction extends ActionSupport {

	public String msg;
	public boolean success;
	private String name;
	private String password;

	private String stuid;
	private String tel;
	private String sex;
	private String qq;
	private String email;
	private String grade_class;
	private String birthday;

//	UserManager um = new UserManagerImpl();\
	private UserManager um ;

	public UserResiterAction() {
		ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
		um = (UserManager)ctx.getBean("userManager");
	}

	@Resource(name="userManager")
	public void setUm(UserManager um) {
		this.um = um;
	}

	public String execute() throws Exception {
//		System.out.println(username);
		System.out.println(name);
		System.out.println(password);
		System.out.println(stuid);
		System.out.println(tel);
		System.out.println(sex);
		System.out.println(qq);
		System.out.println(email);
		System.out.println(grade_class);
		System.out.println(birthday);
		char[] c = birthday.toCharArray();
		  for (int i = 0;i < c.length;i ++)
		  {
		   System.out.println(c[i]);
		  }
		ConvertUtil cu =new ConvertUtil();
		User u = new User();
		u.setName(name);
		u.setPassword(cu.MD5(password));
		u.setScore(0);
		u.setStuid(stuid);
		u.setTel(tel);
		u.setSex(sex);
		u.setQq(qq);
		u.setEmail(email);
		u.setGrade_class(grade_class);
		String birthday2=cu.getTime2(birthday);
		System.out.println("new date="+birthday2);
		u.setBirthday(birthday2);
		u.setDirection("NO");
		u.setIntro("Empty");

//		if(um.exists(u)) {
//			this.msg="注册失败存在用户";
//			return "fail";
//		}
//		um.add(u);
		this.msg="注册成功";
		return SUCCESS;
	}

//	public String getName() {
//		return name;
//	}

	public void setName(String name) {
		this.name = name;
	}

//	public String getPassword() {
//		return password;
//	}

	public void setPassword(String password) {
		this.password = password;
	}

//	public String getStuid() {
//		return stuid;
//	}

	public void setStuid(String stuid) {
		this.stuid = stuid;
	}

//	public String getTel() {
//		return tel;
//	}

	public void setTel(String tel) {
		this.tel = tel;
	}

//	public String getSex() {
//		return sex;
//	}

	public void setSex(String sex) {
		this.sex = sex;
	}
//
//	public String getQq() {
//		return qq;
//	}

	public void setQq(String qq) {
		this.qq = qq;
	}
//
//	public String getEmail() {
//		return email;
//	}

	public void setEmail(String email) {
		this.email = email;
	}

//	public String getGrade_class() {
//		return grade_class;
//	}

	public void setGrade_class(String grade_class) {
		this.grade_class = grade_class;
	}

//	public String getBirthday() {
//		return birthday;
//	}

	public void setBirthday(String birthday) {
		this.birthday = birthday;
	}

	public void setMsg(String msg) {
		this.msg = msg;
	}

	public void setSuccess(boolean success) {
		this.success = success;
	}

}

把getUm去掉就行了，，其他get*注释掉是解决的时候尝试的 发现去了不影响 因为得到值是由 set方法

为什么getUm去掉，也就是一般的 get*Service去掉 ？我也不懂。。。
