三、代码参考
Java项目实战代码参考1：
@RequestMapping("/admin/category")
@Controller
public class AdminCategoryController {
@Autowired
CategoryService categoryService;
@Autowired
UserService userService;
@RequestMapping("/update")
public @ResponseBody
ResultDto update(Long categoryId, String categoryName){
if(categoryId <= 0){
return new ResultDto(false,"id is null");
}
Category category = categoryService.get(categoryId);
if(null == category){
return new ResultDto(false,"category not exist");
}
category.setName(categoryName);
categoryService.update(category);
return new ResultDto(true);
}
@RequestMapping("/delete")
public @ResponseBody ResultDto delete(Long categoryId){
if(categoryId <= 0){
return new ResultDto(false,"id is null");
}
categoryService.delete(categoryId);
return new ResultDto(true);
}
@RequestMapping("/save")
public @ResponseBody ResultDto save(String categoryName,HttpSession session){
if(null == categoryName || "".equals(categoryName)){
return new ResultDto(false,"name is null");
}
User user = userService.get((Long)session.getAttribute(SessionConstants.USER_ID));
Category category = new Category();
category.setName(categoryName);
category.setAuthor(user);
category.setPublishTime(new Date());
category.setState(EntityConstants.CATEGORY_STATE_NORMAL);
categoryService.save(category);
return new ResultDto(true);
}
} Java项目实战代码参考2：
@Controller
@RequestMapping("/admin")
public class AdminHomeController {
@Autowired
CategoryService categoryService;
@Autowired
UserService userService;
@Autowired
ActivityCheckSerivce activityCheckSerivce;
@RequestMapping({"","/index"})
public String index(){
return "redirect:/admin/category";
}
@RequestMapping("/category")
public String list(Model model, HttpSession session){
List<Category> categoryList = categoryService.list();
model.addAttribute("categoryList",categoryList);
model.addAttribute("user",userService.get((Long)session.getAttribute(SessionConstants.USER_ID)));
return "admin/category";
}
@RequestMapping("/check")
public String checkList(@RequestParam(defaultValue = "0") int pageNum, @RequestParam(defaultValue = "10") int pageSize, Model model){
SystemContext.setPageSize(15);
Page<ActivityCheck> activityCheckPager = activityCheckSerivce.getPager(pageNum, pageSize);
model.addAttribute("activityCheckPager",activityCheckPager);
return "admin/check";
}
} Java项目实战代码参考3：
@Controller
@RequestMapping("/user/score")
public class ScoreController {
@Autowired
ScoreService scoreService;
@Autowired
UserService userService;
@Autowired
ActivityService activityService;
@Autowired
EnrollService enrollService;
@RequestMapping("/update")
public @ResponseBody
ResultDto update(Long scoreId,Double scoreValue){
Score score = scoreService.get(scoreId);
score.setScore(scoreValue);
scoreService.update(score);
return new ResultDto(true);
}
@RequestMapping("/save")
public @ResponseBody ResultDto save(Long activityId,Long userId,Double scoreValue,Integer round){
if(!enrollService.hasEnrolled(activityId,userId)){
return new ResultDto(false,"该用户未报名此次活动");
}
Activity activity = activityService.get(activityId);
if(round == null || round > activity.getRound()){
return new ResultDto(false,"超出最大阶段数量:"+round);
}
Score score = new Score();
score.setUser(userService.get(userId));
score.setActivity(activity);
score.setScore(scoreValue);
score.setRound(round);
scoreService.save(score);
return new ResultDto(true);
}
@RequestMapping("/delete")
public @ResponseBody ResultDto delete(Long scoreId){
scoreService.delete(scoreId);
return new ResultDto(true);
}
