Java控制器和服务-在服务中实现Getter和Setter

spring java

Futuregeek · 技术社区 · 6 年前

我有以下控制器和服务类,

用户控制器.java:

@RequestMapping(value = "/user/getUser")
@ResponseBody
public Map<String, Object> getUser(@ModelAttribute UserRequestModel userRequest, HttpServletRequest request)
        throws Exception {
    final IContext context = contextFactory.getContext(request);
    Map<String, Object> responseMap = new HashMap<>();

    String UserID = userService.getUserID(context, userRequest.getName());

    if (UserID != null) {
        UserDetails userDetails = userService.getUserDetails(context, userID);
        ...
    }

    ...

 return responseMap;
}

------
@RequestMapping(value = "/user/Booking")
@ResponseBody
public Map<String, Object> Booking(@RequestParam("bookingRequest") String RequestAsJSON,HttpServletRequest request) throws Exception {
    Map<String, Object> responseMap = new HashMap<>();

    final IContext context = contextFactory.getContext(request);
    UserList userList = userService.getUserList(context, RequestAsJSON);
    IUserResponse userresponse = userService.createBooking(RequestAsJSON, context, userList);
    return responseMap;
}

也遵循服务级别,

UserService.java

@Override
public String getUserID(IContext requestContext, String userName) {
   String userID = null;
   List<User> users = createUser(context, userName);
   userID = <API>.getID(context, userList);
   return userID;
}

@Override
public UserDetails getUserDetails(IContext context, String userID) {
   UserDetails userDetails = null;
   userDetails = <API>.getUserDetails(userID, context);
   return userDetails;
}

@Override
public UserList getUserList(IContext context, String requestAsJSON) {
    JsonObject requestObj = new JsonParser().parse(requestAsJSON).getAsJsonObject();
    String userName = requestObj.get("Name").getAsString();
    UserCard userCard = createCard(userName);
    List<User> users = new ArrayList<>();
    users.add(userCard);
    UserList userList = new UserList();
    userList.setUsers(users);
    ..

    return userList;
}
    ....
private List<User> createUser(IContext context, String userName) {
   List<User> users = new ArrayList<>();
   UserCard userCard = createCard(userName);
   users.add(userCard);
   return users;
}

private UserCard createCard(String userName) {
   UserCard userCard = new UserCard();
   userCard.setOfficeID(12345);
   userCard.setAddress("Addr1");
   userCard.setOffice(âTestâ);
   return userCard;
}

目前 createCard 方法在获取用户(“/user/getUser”)和预订(“/user/booking”)时调用两次。

我想 while“/user/getUser”并在“/user/Booking”时获取此卡。我想在创建getter和setter方面得到帮助。

在你的服务中,你可以使用 Map 储存 name 和 userCard

static Map<String , UserCard> userCardInfo = new HashMap<>();

//inside createUser populate it

private List<User> createUser(IContext context, String userName) {
    List<User> users = new ArrayList<>();
    UserCard userCard = createCard(userName);
    users.add(userCard);
    this.userCardInfo.put(userName , userCard);
    return users;
}

//and inside getUserList retrieve from that map

public UserList getUserList(IContext context, String requestAsJSON) {
    JsonObject requestObj = new JsonParser().parse(requestAsJSON).getAsJsonObject();
    String userName = requestObj.get("Name").getAsString();
    UserCard userCard = null;
    if(this.userCardInfo.containsKey(userName)) {
        userCard = this.userCardInfo.get(userName);
    } else {
        userCard = createCard(userName);
    }

    List<User> users = new ArrayList<>();
    users.add(userCard);
    UserList userList = new UserList();
    userList.setUsers(users);
    return userList;
}

这两个是单独的请求。休息是无状态的所以你怎么能做到?最好的选择是,您可以将第一次请求时创建的数据传递到客户端。然后为了 第二次请求 请求体 . 可以将数据放在静态变量上,但这不是一个好的做法。

你可以这样做:

if (UserID != null) {
            UserDetails userDetails = userService.getUserDetails(context, userID);
            responseMap.put("userDetails",userDetails);
        }

当从客户端调用时,客户端应该 . 生成将接受的请求在请求
