LoginService
package service; import common.Account; import common.Response; import entity.User; import java.util.ArrayList; import java.util.List; public class LoginService { private static List<User> userList = new ArrayList(); static{ userList.add(new User(Account.ADMIN.getUsername(), Account.ADMIN.getPassword())); userList.add(new User(Account.USER1.getUsername(), Account.USER1.getPassword())); userList.add(new User(Account.USER2.getUsername(), Account.USER2.getPassword())); userList.add(new User(Account.USER3.getUsername(), Account.USER3.getPassword())); } public Response login(String username, String password){ if(username == null || "".equals(username)){ return new Response("error","用户名为空，请输入用户名。"); } if(password == null || "".equals(password)){ return new Response("error","密码为空，请输入密码。"); } for (User user : userList){ if(username.equals(user.getUsername()) && password.equals(user.getPassword())){ return new Response("success","登陆成功！"); } } return new Response("error","用户名或密码输入错误，请检查并重新输入。"); } }
