RESTFul API设计指南及使用说明
RESTFul API设计指南及使用说明
一、 协议
API与用户的通信协议,使用HTTP协议。
二、 域名
应尽量将API部署在专用域名之下(http://api.example.com)
也可以将API放在主域名下(http://example.com/api)
三、 版本
应该将API的版本号放入URL(http://example.com/api/v1.0)
四、 路径与映射
REST的关键原则与将你的API分割成逻辑资源紧密相关。使用HTTP请求控制这些资源,
RESTFul原则提供了HTTP methods映射作为策略来处理CRUD actions,
需要继承Resource父类如下:
@API():类注解,括号类为类请求路径,如@API("/api/v1.0")
@GET():方法注解,查询,括号内为方法请求路径,如GET("/user"),如果通过API直接访问,括号可不加
@GET("/:id"):方法注解,根据ID查询,括号内表示可根据ID直接查询结果
@POST():方法注解,新增,括号内为方法请求路径,如果通过API直接访问,括号可不加
@PUT():方法注解,修改,括号内为方法请求路径,如果通过API直接访问,括号可不加
@DELETE():方法注解,删除,括号内为方法请求路径,如果通过API直接访问,括号可不加
五、 资源(Model)常用方法,需要继承Model父类
1:findBy(String where,Object... params):根据条件查询
1 public List<M> findBy(String username,String password){ 2 Model modelDao = new Model(); 3 List<M> list = modelDao.findBy("username=? AND password=?",username,password); 4 return list; 5 }
2:findById(Object id):根据ID查询
1 public Model findById(Object id){ 2 Model modelDao = new Model(); 3 Model model = modelDao.findById(id); 4 return model; 5 }
3: findFirstBy(String where,Object... params):根据条件查询,返回第一条数据
1 public Model findFirstBy(String username,String password){ 2 Model modelDao = new Model(); 3 Model model = modelDao.findFirstBy("username=? AND password=?",username,password); 4 return model; 5 }
4: findAll():查询所有
1 public List<M> findAll(){ 2 Model modelDao = new Model(); 3 List<M> list = modelDao.findAll(); 4 return list; 5 }
5:findColsBy(String colums, String where, Object... params):查询相关列信息
1 public List<M> findColsBy(String username,String password){ 2 Model modelDao = new Model(); 3 List<M> list = modelDao.findColsBy("id,username,password","username=? AND password=?",username,password) 4 return list; 5 }
6: save():添加
1 public boolean save(){ 2 Model model = new Model(); 3 model.set("username","test"); 4 model.set("password","123456"); 5 boolean flag = model.save(); 6 return flag; 7 }
7:save(Model model):添加
1 public boolean save(Model model){ 2 Model modelDao = new Model(); 3 boolean flag = modelDao.save(model); 4 return flag; 5 }
8:save(List<M> list):批量添加
1 public boolean save(List<M> list){ 2 Model modelDao = new Model(); 3 boolean flag = modelDao.save(list); 4 return flag; 5 }
9:update():更新
1 public boolean update(){ 2 Model model = new Model(); 3 model.set("id",1); 4 model.set("username","test"); 5 model.set("password","123456"); 6 boolean flag = model.update(); 7 return flag; 8 }
10:update(String sql,Object... params):更新或删除 sql为更新语句时更新,为删除语句时删除
1 public boolean update(String username,String password,int id){ 2 Model modelDao = new Model(); 3 String sql = "update user set username=?,password=? where id=?"; 4 boolean flag = modelDao.update(sql,username,password,id); 5 return flag; 6 }
11:delete():删除
1 public boolean delete(){ 2 Model model = new Model(); 3 model.set("id",1); 4 boolean flag = model.delete(); 5 return flag; 6 }
12:deleteBy(String where,Object... params):根据条件删除
1 public boolean deleteBy(String username,String password){ 2 Model modelDao = new Model(); 3 boolean flag = modelDao.deleteBy("username=? AND password=?",username,password); 4 return flag; 5 }
13:deleteById(Object id):根据ID删除
1 public boolean deleteById(int id){ 2 Model modelDao = new Model(); 3 boolean flag = modelDao.deleteById(id); 4 return flag; 5 }
14:fullPaginate(int pageNumber, int pageSize, String sql, Object... params):分页查询
1 public FullPage<M> fullPaginate(int pageNumber, int pageSize,String username,String password) { 2 Model modelDao = new Model(); 3 String sql = "select * from user where username=? AND password=?"; 4 FullPage<M> fullPage = modelDao.fullPage(pageNumber,pageSize,sql,username,password); 5 return fullPage; 6 }
//注:fullPage.getList()获取查询结果 fullPage.getTotalRow()获取总条数
