该项目是一个基于Spring Boot的校园新闻数据化系统，可以用于计算机毕设。以下是一些可能的功能和代码示例：
- 用户登录和注册：
@RestController
public class UserController {
@Autowired
private UserService userService;
@PostMapping("/register")
public ResponseResult<String> register(@RequestBody UserRegisterRequest request) {
return userService.register(request);
}
@PostMapping("/login")
public ResponseResult<UserDTO> login(@RequestBody UserLoginRequest request) {
return userService.login(request);
}
}
- 新闻管理：
@RestController
@RequestMapping("/news")
public class NewsController {
@Autowired
private NewsService newsService;
@PostMapping("/add")
public ResponseResult<Void> addNews(@RequestBody NewsAddRequest request) {
return newsService.addNews(request);
}
@GetMapping("/list")
public ResponseResult<List<NewsDTO>> listNews(@RequestParam Map<String, String> params) {
return newsService.listNews(params);
}
@PostMapping("/delete/{id}")
public ResponseResult<Void> deleteNews(@PathVariable("id") Long id) {
return newsService.deleteNews(id);
}
@PostMapping("/update")
public ResponseResult<Void> updateNews(@RequestBody NewsUpdateRequest request) {
return newsService.updateNews(request);
}
}
- 用户权限管理：
@Component
public class UserDetailsServiceImpl implements UserDetailsService {
@Autowired
private UserService userService;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
UserDTO user = userService.getUserByUsername(username);
if (user == null) {
throw new UsernameNotFoundException("用户不存在");
}
return new UserDetailsImpl(user);
}
}
- 新闻数据可视化（使用ECharts）：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>新闻数据可视化</title>
<script src="path/to/echarts.min.js"></script>
</head>
<body>
<div id="main" style="width: 600px;height:400px;"></div>
<script type="text/javascript">
var myChart = echarts.init(document.getElementById('main'));
var option = {
// ECharts 配置项
};
myChart.setOption(option);
</script>
</body>
</html>
这些代码片段和HTML页面提供了一个基本框架，展示了如何实现用户登录注册、新闻管理、以及用户权限管理等功能。具
