介绍：按照指定的本地目录进行restful接口扫描
原理：根据正则先匹配@RequestMapping后面的内容然后再匹配PostMapping|PutMapping|DeleteMapping|GetMapping后面的内容
正则1
@RequestMapping\("([^"]+)"//这个匹配RequestMapping后面括号里面的内容正则2
@(PostMapping|PutMapping|DeleteMapping|GetMapping)\\(\"([^\"]*)\"\\)"//这个匹配这四个Mapping后面括号里面的内容例子：
url
入参
{
"path" : "E:\\desktop\\ruoyi-vue-pro-master\\yudao-module-system\\yudao-module-system-biz\\src\\main\\java\\cn\\iocoder\\yudao\\module\\system\\controller\\admin\\dept"
}结果
{
"code": 200,
"message": "成功扫描到数据",
"data": [
"post /system/dept/create",
"put /system/dept/update",
"delete /system/dept/delete",
"get /system/dept/list",
"get /system/dept/list-all-simple",
"get /system/dept/get",
"post /system/post/create",
"put /system/post/update",
"delete /system/post/delete",
"get /system/post/list-all-simple",
"get /system/post/page",
"get /system/post/export"
]
}注意现只支持注解括号里面的默认值，如下面的@PostMapping("create")就可以识别出来，暂不支持其他形式的写法如（@PostMapping(value="create")）之类的
@Tag(name = "管理后台 - 部门")
@RestController
@RequestMapping("/system/dept")
@Validated
public class DeptController {
@Resource
private DeptService deptService;
@PostMapping("create")
@Operation(summary = "创建部门")
@PreAuthorize("@ss.hasPermission('system:dept:create')")
public CommonResult<Long> createDept(@Valid @RequestBody DeptCreateReqVO reqVO) {
Long deptId = deptService.createDept(reqVO);
return success(deptId);
}
@PutMapping("update")
@Operation(summary = "更新部门")
@PreAuthorize("@ss.hasPermission('system:dept:update')")
public CommonResult<Boolean> updateDept(@Valid @RequestBody DeptUpdateReqVO reqVO) {
deptService.updateDept(reqVO);
return success(true);
}
@DeleteMapping("delete")
@Operation(summary = "删除部门")
@Parameter(name = "id", description = "编号", required = true, example = "1024")
@PreAuthorize("@ss.hasPermission('system:dept:delete')")
public CommonResult<Boolean> deleteDept(@RequestParam("id") Long id) {
deptService.deleteDept(id);
return success(true);
}
@GetMapping("/list")
@Operation(summary = "获取部门列表")
@PreAuthorize("@ss.hasPermission('system:dept:query')")
public CommonResult<List<DeptRespVO>> getDeptList(DeptListReqVO reqVO) {
List<DeptDO> list = deptService.getDeptList(reqVO);
list.sort(Comparator.comparing(DeptDO::getSort));
return success(DeptConvert.INSTANCE.convertList(list));
}
@GetMapping("/list-all-simple")
@Operation(summary = "获取部门精简信息列表", description = "只包含被开启的部门，主要用于前端的下拉选项")
public CommonResult<List<DeptSimpleRespVO>> getSimpleDeptList() {
// 获得部门列表，只要开启状态的
DeptListReqVO reqVO = new DeptListReqVO();
reqVO.setStatus(CommonStatusEnum.ENABLE.getStatus());
List<DeptDO> list = deptService.getDeptList(reqVO);
// 排序后，返回给前端
list.sort(Comparator.comparing(DeptDO::getSort));
return success(DeptConvert.INSTANCE.convertList02(list));
}
@GetMapping("/get")
@Operation(summary = "获得部门信息")
@Parameter(name = "id", description = "编号", required = true, example = "1024")
@PreAuthorize("@ss.hasPermission('system:dept:query')")
public CommonResult<DeptRespVO> getDept(@RequestParam("id") Long id) {
return success(DeptConvert.INSTANCE.convert(deptService.getDept(id)));
}
}问题小结
一开始没有把文件一次性全部读进来导致识别有问题，因为这个逻辑就是根据一整个文件从上到下的一个顺序来写的
public class readSpecificFile {
public static void main(String[] args) {
String directoryPath = "E:\\desktop\\pro\\src\\main\\java\\org\\example\\controller"; // 指定目录的路径
File directory = new File(directoryPath);
if (!directory.isDirectory()) {
System.err.println("指定路径不是一个目录");
return;
}
File[] files = directory.listFiles(); // 获取目录中的所有文件
if (files == null || files.length == 0) {
System.out.println("目录中没有文件");
return;
}
List<String> list=new ArrayList<>();
for (File file : files) {
if (file.isFile()) {
System.out.println(file.getName()); // 输出文件名
// 在这里可以使用FileInputStream等类读取文件内容
Pattern requestMappingPattern = Pattern.compile("@RequestMapping\\(\"([^\"]+)\""); // 匹配@RequestMapping注解的正则表达式模式
Pattern mappingPattern = Pattern.compile("@(PostMapping|PutMapping|DeleteMapping|GetMapping)\\(\"([^\"]*)\"\\)");
// 正则表达式匹配模式
try {
//这一块读取文件
FileInputStream inputStream = new FileInputStream(file);
byte[] buffer = new byte[1024];
int len;
while ((len = inputStream.read(buffer)) != -1) {
/**改成了下面这种方式
* try (BufferedReader br = new BufferedReader(new FileReader(file))) {
* StringBuilder contentBuilder = new StringBuilder();
* String line;
* while ((line = br.readLine()) != null) {
* contentBuilder.append(line).append(System.lineSeparator());
* }
*/
String content = new String(buffer, 0, len, "UTF-8");
Matcher requestMappingMatcher = requestMappingPattern.matcher(content); // 匹配@RequestMapping注解
String requestParameter="";
while (requestMappingMatcher.find()) {
requestParameter = requestMappingMatcher.group(1); // 获取注解参数
}
Matcher mappingMatcher = mappingPattern.matcher(content);
while (mappingMatcher.find()) {
//加入集合。。。
}
}
}
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
for (String s:list) {
System.out.println(s);
}
}
}
