        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(移动端是根据我的GitHub
RxjavaRetrofit 项目修改而来的)

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~。
