基于springboot的校园新闻数据化系统

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
