微信里收集毕业论文

毕业论文选题系统是基于微信小程序，后端是基于java编程语言，ssm框架，mysql数据库和IDEA工具开发，本系统分为学生，教师，管理员三个角色；学生可以注册登陆系统，查看系统公告，选课论文课题，提交课题论文，查看论文审核，答辩结果等信息；教师可以发布课题，审核学生论文，课题答辩结果，在线回复学生留言；管理员对学生，教师，公告，论文，选题，答辩等进行管理；本系统功能齐全，文档齐全，适合作为微信小程序毕业设计来参考和学习。一.技术环境jdk版本： 及以上ide工具：IDEA ，微信小程序开发工具数据库: （必须）编程语言: Javatomcat: 及以上java框架：SSMmaven: 前端：layui ，微信详细技术：HTML+CSS+JS+JSP+JAVA+SSM+MYSQL+JQUERY+MAVEN+微信开发工具二.项目文件（项目获取请看文末官网）在这里插入图片描述三.系统功能在这里插入图片描述四.代码示例package ;/** * 和登陆有关的都在这里 */import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;@Controller("loginController")@Scope("prototype")public class LoginController extends ActionSupport { @Autowired private UserService userService; @Autowired private RoleService roleService; private User user; private Map map = new HashMap(); public User getUser() { return user; } public void setUser(User user) { = user; } public UserService getUserService() { return userService; } public void setUserService(UserService userService) { = userService; } /** * 用户登陆 * @return */ public void index() throws IOException { User user1 = (user); if (user1 != null){ if (() == 1){ if (().getEnName().equals("admin")){ ().getSession().put("user", user1); } if (().getEnName().equals("js")){ ().getSession().put("user1", user1); } if (().getEnName().equals("xs")){ ().getSession().put("user2", user1); } ("flag", 1); ("url", ""); ("id", ()); (map); } else { ("flag", 2); (map); } } else { ("flag", 3); (map); } } public String indexs() throws IOException { User u = (); if (u != null){ ().put("user", u); String ss = ().getEnName(); ().put("role", ().getEnName()); } return SUCCESS; } //登陆页面 public String login() { return SUCCESS; } //退出 public String tuichu() { ActionContext ac = (); Map session = (); ("userName"); ("userId"); ().getSession().invalidate(); return "login"; }}package ;/** * 用户新增 */import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;import ;@Controller("userController")@Scope("prototype")public class UserController extends ActionSupport implements ModelDriven { @Autowired private UserService userService; @Autowired private RoleService roleService; private User user; private Integer userId; private Map map = new HashMap();/** * list * * @return */ public String list() throws IOException { User user1 = (); if (user1 == null || () == null){ ().put("login", 1); return SUCCESS; } Pager pagers = null; Role role = (); if (().equals("admin")) { pagers = (user); ().put("pagers", pagers); ().put("user", user1); ().put("role", role); ().put("bean", user); return SUCCESS; } else if (().equals("xs") || ().equals("js")) { pagers = (user1); ().put("pagers", pagers); ().put("bean", user); return SUCCESS; } return null; }/** * 跳转add * * @return */ public String add() { Pager pagers = (); ().put("pagers", pagers); return SUCCESS; } /** * 查询修改 * * @return */ public String edit() { User bean = (userId); Pager pagers = (); ().put("bean", bean); ().put("pagers", pagers); return SUCCESS; }/** * 审核 * * @return */ public void updateSh() throws IOException { (1); (user); ("flag", true); ("url", ""); (map); } /** * 更新 * * @return */ public String update() throws IOException { if (().equals("")){ (null); } (user); ("flag", true); ("url", ""); (map); return SUCCESS; } /** * 保存 * * @return */ public void save() throws IOException { if ((user) != null){ ("flag", false); ("url", ""); (map); } else { (new Date()); (user); ("flag", true); ("url", ""); (map); } } public void delete() throws IOException { User user1 = (userId); (1); (user1); ("flag", true); ("url", ""); (map); } @Override public User getModel() { if (user == null) { user = new User(); } return user; } public Integer getUserId() { return userId; } public void setUserId(Integer userId) { = userId; } public User getUser() { return user; } public void setUser(User user) { = user; }}
