移动大脑-SpringMVc搭建RestFul后台服务（三）-RestFul接口编写（模拟用户注册登录）

        接着上一篇博客《移动大脑-SpringMVc搭建RestFul后台服务（二）-配置mysql数据库》 ，已经配置好了Mysql数据库，现在开始编写RestFul接口了，模拟实现用户的注册（PUT）和登录（POST）两个接口：

还是最经典的action-service-dao结构

一、创建UserDao.java接口和实现类UserDaoImpl.java

package com.ywl5320.appservice.dao;

import com.ywl5320.appservice.bean.UserBean;

/**
 * Created by ywl5320 on 2017/10/12.
 */
public interface UserDao {

    /**
     * 注册
     * @param userBean
     */
    UserBean registor(UserBean userBean);

    /**
     * 登陆
     * @return
     */
    UserBean login(String phone, String password);

    /**
     * 根据名字获取用户信息
     * @param phone
     * @return
     */
    UserBean getUser(String phone);

}

package com.ywl5320.appservice.dao;

import com.ywl5320.appservice.bean.UserBean;
import org.springframework.orm.hibernate5.support.HibernateDaoSupport;

import java.util.List;

/**
 * Created by ywl5320 on 2017/10/12.
 */
public class UserDaoImpl extends HibernateDaoSupport implements UserDao {

    public UserBean login(String phone, String password) {
        List<UserBean> users = (List<UserBean>) this.getHibernateTemplate().find("from UserBean where phone=? and password=?", phone, password);
        if(users != null && users.size() > 0)
        {
            return users.get(0);
        }
        return null;
    }

    public UserBean registor(UserBean userBean) {
        this.getHibernateTemplate().save(userBean);
        return getUser(userBean.getPhone());
    }

    public UserBean getUser(String phone) {
        List<UserBean> users = (List<UserBean>) this.getHibernateTemplate().find("from UserBean where phone=?", phone);
        if(users != null && users.size() > 0)
        {
            return users.get(0);
        }
        return null;
    }
}

这里实现类继承了HibernateDaoSupport类，就可以使用hibernate的语句操作数据库了。

二、编写UserService.java类

package com.ywl5320.appservice.service;

import com.ywl5320.appservice.bean.RestFulBean;
import com.ywl5320.appservice.bean.UserBean;
import com.ywl5320.appservice.dao.UserDao;
import com.ywl5320.appservice.util.RestFulUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.transaction.annotation.Transactional;

/**
 * Created by ywl5320 on 2017/10/12.
 */
@Transactional
public class UserService {

    @Autowired
    private UserDao userDao;

    public RestFulBean<UserBean> registorServer(UserBean userBean)
    {
        UserBean user = userDao.getUser(userBean.getPhone());
        if(user != null)
        {
            return RestFulUtil.getInstance().getResuFulBean(null, 1, "已经注册过了");
        }
        else
        {

            user = userDao.registor(userBean);
            if(user != null)
            {
                return RestFulUtil.getInstance().getResuFulBean(user, 0, "注册成功");
            }
            else{
                return RestFulUtil.getInstance().getResuFulBean(null, 1, "注册失败");
            }
        }

    }

    public RestFulBean<UserBean> login(String phone, String password)
    {
        UserBean user = userDao.login(phone, password);
        if(user != null)
        {
            return RestFulUtil.getInstance().getResuFulBean(user, 0, "登录成功");
        }
        else
        {
            return RestFulUtil.getInstance().getResuFulBean(null, 1, "用户不存在");
        }
    }

}

这里用了注解@Transactional和@Autowired来自动扫描service和注入实体类。

三、在beans.xml中配置service和dao

<!-- 配置server -->
    <bean id="loginService" class="com.ywl5320.appservice.service.UserService"/>
    <!-- 配置dao -->
    <bean id="userDaoImpl" class="com.ywl5320.appservice.dao.UserDaoImpl">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>

四、编写UserAction.java

package com.ywl5320.appservice.action;

import com.ywl5320.appservice.bean.RestFulBean;
import com.ywl5320.appservice.bean.UserBean;
import com.ywl5320.appservice.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;

/**
 * Created by ywl5320 on 2017-10-2.
 */
@Controller
@RequestMapping("/user")
public class UserAction {

    @Autowired
    private UserService userService;


    /**
     * 注册
     * @param userBean
     * @return
     */
    @ResponseBody
    @RequestMapping(value="/register.do", method= RequestMethod.PUT)
    public RestFulBean<UserBean> register(@RequestBody UserBean userBean)
    {
        return userService.registorServer(userBean);
    }

    /**
     * 登录
     * @param phone
     * @return
     */
    @ResponseBody
    @RequestMapping(value="/loginbypwd.do", method= RequestMethod.POST)
    public RestFulBean<UserBean> loginByPwd(String phone, String password)
    {
        System.out.println("phone:" + phone);
        return userService.login(phone, password);
    }

}

注册接口：/user/register.do

登录接口：/user/loginbypwd.do

RestFulUtil.java

package com.ywl5320.appservice.util;

import com.ywl5320.appservice.bean.RestFulBean;

/**
 * Created by ywl5320 on 2017-10-15.
 */
public class RestFulUtil<T> {

    private RestFulUtil(){}

    public static RestFulUtil getInstance()
    {
        return new RestFulUtil();
    }

    public RestFulBean<T> getResuFulBean(T o, int status, String msg)
    {
        RestFulBean<T> objectRestFulBean = new RestFulBean<T>();
        objectRestFulBean.setStatus(status);
        objectRestFulBean.setMsg(msg);
        objectRestFulBean.setData(o);
        return objectRestFulBean;
    }

}

整体目录如下：

五、启动服务，移动端访问测试 1、注册：

2、注册2

3、登录

4、数据库数据

源码下载：GitHub 服务端（AppServiceRestFul）和移动端（RxJavaRetrofit）

OK，这样就完成了注册登录接口了，移动端可以顺利访问。下一篇会添加token和过滤器。~~接着看SKT vs EDG了，目测后期EDG有点难了~。
