action中的代码

public class CustomerAction extends ActionSupport {
	//action中因为在配置文件中注入了service层的对象，所以在这儿可以引用，但是需要天机set方法
	private CustomerService customerService;
	public void setCustomerService(CustomerService customerService) {

	//前台传入的请求参数保存到值栈中，，在这儿可以获取

	//根据主键查询
	public String findOne() throws Exception {
		Customer customer = customerService.findOne(custId);
		ActionContext.getContext().getValueStack().push(customer);
		return SUCCESS;
	}
	
}

service层的代码

public class CustomerServiceImpl implements CustomerService {

	private CustomerDao customerDao;
	public void setCustomerDao(CustomerDao customerDao) {
		this.customerDao = customerDao;
	}
	public Customer findOne(String custId) {

DAO层的代码

//继承HibernateDaoSupport 
public class CustomerDaoImpl extends HibernateDaoSupport implements CustomerDao {

	public Customer findOne(String custId) {
		return this.getHibernateTemplate().get(Customer.class, custId);
	}
