@Data
@TableName("sys_user")
public class User {@TableId(type = IdType.AUTO)private Long id;@NotBlank(message = "用户名不能为空")private String username;@NotBlank(message = "密码不能为空")private String password;private String realName;private String email;private String phone;private Integer status;private LocalDateTime createTime;private LocalDateTime updateTime;@TableField(exist = false)private List<Role> roles;
}// Document.java
@Data
@TableName("oa_document")
public class Document {@TableId(type = IdType.AUTO)private Long id;@NotBlank(message = "文档标题不能为空")private String title;private String content;private String filePath;private String fileType;private Long fileSize;private Long creatorId;private LocalDateTime createTime;private LocalDateTime updateTime;private Integer status;private String keywords;@TableField(exist = false)private User creator;
}// ApprovalProcess.java
@Data
@TableName("oa_approval_process")
public class ApprovalProcess {@TableId(type = IdType.AUTO)private Long id;@NotBlank(message = "流程名称不能为空")private String processName;private String processKey;private Integer status;private String description;private LocalDateTime createTime;private LocalDateTime updateTime;@TableField(exist = false)private List<ApprovalNode> nodes;
}// Meeting.java
@Data
@TableName("oa_meeting")

}
2. 数据库连接配置
// MyBatisConfig.java
@Configuration
public class MyBatisConfig {@Beanpublic SqlSessionFactory sqlSessionFactory(DataSource dataSource) throws Exception {SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();factoryBean.setDataSource(dataSource);// 设置MyBatis配置org.apache.ibatis.session.Configuration configuration = new org.apache.ibatis.session.Configuration();configuration.setMapUnderscoreToCamelCase(true);configuration.setCacheEnabled(true);factoryBean.setConfiguration(configuration);// 设置TypeAliases包factoryBean.setTypeAliasesPackage("com.officeautomation.entity");// 设置MapperLocationsResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();factoryBean.setMapperLocations(resolver.getResources("classpath:mapper/*.xml"));return factoryBean.getObject();}@Beanpublic PlatformTransactionManager transactionManager(DataSource dataSource) {return new DataSourceTransactionManager(dataSource);}
}
3. 服务层实现
// UserServiceImpl.java
@Service
@Transactional
public class UserServiceImpl implements UserService {@Autowiredprivate UserMapper userMapper;@Autowiredprivate RoleMapper roleMapper;@Overridepublic User getUserById(Long id) {User user = userMapper.selectById(id);if (user != null) {List<Role> roles = roleMapper.getRolesByUserId(id);user.setRoles(roles);}return user;}@Overridepublic User getUserByUsername(String username) {QueryWrapper<User> wrapper = new QueryWrapper<>();wrapper.eq("username", username);User user = userMapper.selectOne(wrapper);if (user != null) {List<Role> roles = roleMapper.getRolesByUserId(user.getId());user.setRoles(roles);}return user;}@Overridepublic List<User> getAllUsers() {List<User> userList = userMapper.selectList(null);for (User user : userList) {List<Role> roles = roleMapper.getRolesByUserId(user.getId());user.setRoles(roles);}return userList;}@Overridepublic boolean saveUser(User user) {if (user.getId() == null) {// 新增用户user.setCreateTime(LocalDateTime.now());user.setUpdateTime(LocalDateTime.now());user.setStatus(1);// 加密密码String password = user.getPassword();user.setPassword(PasswordEncoderUtil.encode(password));int result = userMapper.insert(user);return result > 0;} else {// 更新用户user.setUpdateTime(LocalDateTime.now());// 如果密码不为空，则更新密码if (!StringUtils.isEmpty(user.getPassword())) {user.setPassword(PasswordEncoderUtil.encode(user.getPassword()));} else {// 不更新密码，移除该字段user.setPassword(null);}int result = userMapper.updateById(user);return result > 0;}}@Overridepublic boolean deleteUser(Long id) {int result = userMapper.deleteById(id);// 删除用户角色关联roleMapper.deleteUserRoleByUserId(id);return result > 0;}
}// DocumentServiceImpl.java
@Service
@Transactional
public class DocumentServiceImpl implements DocumentService {@Autowiredprivate DocumentMapper documentMapper;@Autowiredprivate UserService userService;@Overridepublic Document getDocumentById(Long id) {Document document = documentMapper.selectById(id);if (document != null) {User creator = userService.getUserById(document.getCreatorId());document.setCreator(creator);}return document;}@Overridepublic List<Document> getDocumentsByPage(Page<Document> page, DocumentQuery query) {QueryWrapper<Document> wrapper = new QueryWrapper<>();if (!StringUtils.isEmpty(query.getTitle())) {wrapper.like("title", query.getTitle());}if (query.getCreatorId() != null) {wrapper.eq("creator_id", query.getCreatorId());}if (query.getStatus() != null) {wrapper.eq("status", query.getStatus());}if (query.getStartTime() != null) {wrapper.ge("create_time", query.getStartTime());}if (query.getEndTime() != null) {wrapper.le("create_time", query.getEndTime());}wrapper.orderByDesc("create_time");Page<Document> documentPage = documentMapper.selectPage(page, wrapper);List<Document> documentList = documentPage.getRecords();// 设置创建人信息for (Document document : documentList) {User creator = userService.getUserById(document.getCreatorId());document.setCreator(creator);}return documentList;}@Overridepublic boolean saveDocument(Document document, MultipartFile file) {try {if (document.getId() == null) {// 新增文档document.setCreateTime(LocalDateTime.now());document.setUpdateTime(LocalDateTime.now());document.setStatus(1);// 处理上传文件if (file != null && !file.isEmpty()) {String filePath = FileUploadUtil.uploadFile(file, "documents");document.setFilePath(filePath);document.setFileName(file.getOriginalFilename());document.setFileSize(file.getSize());document.setFileType(file.getContentType());}int result = documentMapper.insert(document);return result > 0;} else {// 更新文档document.setUpdateTime(LocalDateTime.now());// 处理上传文件if (file != null && !file.isEmpty()) {// 删除原有文件Document oldDocument = documentMapper.selectById(document.getId());if (oldDocument != null && !StringUtils.isEmpty(oldDocument.getFilePath())) {FileUploadUtil.deleteFile(oldDocument.getFilePath());}String filePath = FileUploadUtil.uploadFile(file, "documents");document.setFilePath(filePath);document.setFileName(file.getOriginalFilename());document.setFileSize(file.getSize());document.setFileType(file.getContentType());}int result = documentMapper.updateById(document);return result > 0;}} catch (Exception e) {e.printStackTrace();return false;}}@Overridepublic boolean deleteDocument(Long id) {// 删除文档前先删除关联文件Document document = documentMapper.selectById(id);if (document != null && !StringUtils.isEmpty(document.getFilePath())) {FileUploadUtil.deleteFile(document.getFilePath());}int result = documentMapper.deleteById(id);return result > 0;}
}
4. 控制器层实现

@RestController
@RequestMapping("/api/users")
@Api(tags = "用户管理")
public class UserController {@Autowiredprivate UserService userService;@GetMapping("/{id}")@ApiOperation("获取用户详情")public Result<User> getUser(@PathVariable Long id) {User user = userService.getUserById(id);return Result.success(user);}@GetMapping@ApiOperation("获取用户列表")public Result<List<User>> listUsers() {List<User> userList = userService.getAllUsers();return Result.success(userList);}@PostMapping@ApiOperation("新增用户")@PreAuthorize("hasAuthority('sys:user:add')")public Result<?> addUser(@RequestBody User user) {boolean result = userService.saveUser(user);if (result) {return Result.success();} else {return Result.error("新增用户失败");}}@PutMapping@ApiOperation("更新用户")@PreAuthorize("hasAuthority('sys:user:edit')")public Result<?> updateUser(@RequestBody User user) {boolean result = userService.saveUser(user);if (result) {return Result.success();} else {return Result.error("更新用户失败");}}@DeleteMapping("/{id}")@ApiOperation("删除用户")@PreAuthorize("hasAuthority('sys:user:delete')")public Result<?> deleteUser(@PathVariable Long id) {boolean result = userService.deleteUser(id);if (result) {return Result.success();} else {return Result.error("删除用户失败");}}
}// DocumentController.java
@RestController
@RequestMapping("/api/documents")
@Api(tags = "文档管理")
public class DocumentController {@Autowiredprivate DocumentService documentService;@GetMapping("/{id}")@ApiOperation("获取文档详情")public Result<Document> getDocument(@PathVariable Long id) {Document document = documentService.getDocumentById(id);return Result.success(document);}@GetMapping@ApiOperation("获取文档列表")public Result<PageInfo<Document>> listDocuments(@RequestParam(required = false, defaultValue = "1") Integer pageNum,@RequestParam(required = false, defaultValue = "10") Integer pageSize,DocumentQuery query) {Page<Document> page = new Page<>(pageNum, pageSize);List<Document> documentList = documentService.getDocumentsByPage(page, query);PageInfo<Document> pageInfo = new PageInfo<>(documentList);pageInfo.setTotal(page.getTotal());pageInfo.setPages((int) page.getPages());return Result.success(pageInfo);}@PostMapping@ApiOperation("新增文档")@PreAuthorize("hasAuthority('oa:document:add')")public Result<?> addDocument(@RequestBody Document document) {boolean result = documentService.saveDocument(document, null);if (result) {return Result.success();} else {return Result.error("新增文档失败");}}@PostMapping("/upload")@ApiOperation("上传文档")@PreAuthorize("hasAuthority('oa:document:add')")public Result<?> uploadDocument(@RequestParam("file") MultipartFile file,@RequestParam("title") String title,@RequestParam("content") String content,@RequestParam("creatorId") Long creatorId) {Document document = new Document();document.setTitle(title);document.setContent(content);document.setCreatorId(creatorId);boolean result = documentService.saveDocument(document, file);if (result) {return Result.success();} else {return Result.error("上传文档失败");}}@PutMapping@ApiOperation("更新文档")@PreAuthorize("hasAuthority('oa:document:edit')")public Result<?> updateDocument(@RequestBody Document document) {boolean result = documentService.saveDocument(document, null);if (result) {return Result.success();} else {return Result.error("更新文档失败");}}@DeleteMapping("/{id}")@ApiOperation("删除文档")@PreAuthorize("hasAuthority('oa:document:delete')")public Result<?> deleteDocument(@PathVariable Long id) {boolean result = documentService.deleteDocument(id);if (result) {return Result.success();} else {return Result.error("删除文档失败");}}
