spring + mybatis + springMVC + maven 实现登陆的一些功能

　　近期的项目，从中学到了很多，现在分享给大家，希望对需要的有帮助

　　分享给大家的是 ssm的整合， 提供app的一些接口和业务层的代码，

　　还是废话少说，直接上代码吧！！！

　　dao层的代码就不贴了，都是逆向工程生成的，直接从servcie层开始

　　UserYzmservice接口：

　　

/**
 * 发送用户验证码
 * @author Administrator
 *
 */
public interface UserYzmService extends BaseService<UserYzm, UserYzmExample, Long>{

         /**
         * @param phone
         * @param yzm
         * @return 校验验证码
         */
        public  boolean  validateYzm(String phone,String yzm);
}

　　

　　BaseService接口：

public interface BaseService  <T, E, P> {

    int countByExample(E example);

    int deleteByExample(E example);

    int deleteByPrimaryKey(P id);

    int insert(T record);

    int insertSelective(T record);

    int updateByExampleSelective( T record,  E example);

    int updateByExample(T record, E example);

    int updateByPrimaryKeySelective(T record);

    int updateByPrimaryKey(T record);
    
    List<T> selectByExample(E example);

    T selectByPrimaryKey(P id);
    
    PageInfo<T> select(E example, int pageNum, int pageSize);
}

　　UserYzmServiceImpl:

@Service("userYzmService")
public class UserYzmServiceImpl extends BaseServiceImpl<UserYzm, UserYzmExample, Long> implements UserYzmService{

    @Autowired
    private UserYzmMapper userYzmMapper;
    /**
     * 校验验证码
     */
    public boolean validateYzm(String phone, String yzm) {
        
        UserYzmExample example = new UserYzmExample();  
        example.setOrderByClause("id desc");
        UserYzmExample.Criteria criteria = example.createCriteria();  
        criteria.andPhoneEqualTo(phone);
        criteria.andCodeEqualTo(Integer.parseInt(yzm));
        List<UserYzm> userYzmlist =userYzmMapper.selectByExample(example);
        if(userYzmlist!=null && userYzmlist.size()>0){
            int  min=    DateUtil.diffMinute(new Date(),userYzmlist.get(0).getCreateTime());
            if(min<10){
                int yzmcode=userYzmlist.get(0).getCode();
                if(Integer.valueOf(yzm).intValue()==yzmcode){
                    return true;
                }
            }
        }
        return false;
    }

    @Override
    public BaseMapper<UserYzm, UserYzmExample, Long> getBaseMapper() {
        // TODO Auto-generated method stub
        return userYzmMapper;
    }
}
