客户

dao层

@Repository
public class CustomerDaoImpl implements ICustomerDao {

    @Autowired
    private HibernateTemplate template;//注入模板，方便开发

    @Override
    public int save(Customer customer) {
        return (int) template.save(customer);
    }

    @Override
    public List<Customer> findByExample(Customer example, int pageNum) {
        return template.findByExample(example, (pageNum - 1) * Const.PAGE_SIZE, Const.PAGE_SIZE);
    }

    @Override
    public int count(Customer cust) {
        List<Customer> list = template.findByExample(cust);
        return list.size();
    }
}

service层

@Service
public class CustomerServiceImpl implements ICustomerService {
    @Autowired
    private ICustomerDao customerDao;

    public Page<Customer> findByExample(Customer customer, int pageNum) {
        //查询客户
        List<Customer> list = customerDao.findByExample(customer, pageNum);
        // 总条数
        int count = customerDao.count(customer);
        //封装成page
        return new Page<Customer>(list, pageNum, count);
    }
}

action层

@Namespace("/") //名称空间
@ResultPath("/jsp/customer") //在所有的地址前面添加前缀
@Component //spring创建action
@Scope("prototype") //多例，action都是多例的
public class CustomerAction implements ModelDriven<Customer> {//模型驱动封装对象
    @Autowired
    private ICustomerService customerService;

    private Customer customer = new Customer();//模型驱动一对要手动创建对象

    private int pageNum = 1;//当前页数，默认是首页

    //配置action
    @Action(value = "list", results = { @Result(name = "success", location = "list.jsp") })
    public String list() throws IOException {
        Page<Customer> page = customerService.findByExample(customer, pageNum);
        ActionContext.getContext().put("page", page);//将结果放到域对象中
        return null;
    }

    //set、get方法

}
