Spring controller的url扫描

为什么80%的码农都做不了架构师？>>>   

spring rest项目url规范

用到很多的url，有的不符合规范，需要统计所有url查看哪些不合理，哪些需要改进的。就写了一个小程序来读取Controller的注解来分析rest所用到的url。添加了递归调用的方式，更方便读取。

分析后的结果

public class RequestMappingUtil {

        private static String controllerUrl = "com.lanaya.web.controller";

        public static void main(String[] args){
            URL resource = RequestMappingUtil.class.getClass().getResource("/" + controllerUrl.replace('.','/'));

            ClassLoader classLoader = Thread.currentThread().getContextClassLoader();

            File directory = new File(resource.getPath());

            }

        public static List exportUrl(File file){

            List urlList = new ArrayList<>();

            try {

                    for (File file1 : files) {
                        urlList.addAll(exportUrl(file1));
                    }
                } else {

                    String fileName = file.getName();
                    Class clazz = Class.forName(controllerUrl + "." + fileName.substring(0, fileName.indexOf(".")));

                        topUrl = requestMapping.value()[0];
                    }

                    Method[] methods = clazz.getMethods();
                    for (Method method : methods) {
                        RequestMapping annotation = method.getAnnotation(RequestMapping.class);
                        if (annotation != null) {
                            String methodUrl = annotation.value()[0];

                            if (methodUrl.startsWith("/")) {
                                urlList.add(topUrl + methodUrl + ":" + (annotation.method().length == 0 ? RequestMethod.GET : annotation.method()[0]));
                            } else {
                                urlList.add(topUrl + File.separator + methodUrl + ":" + (annotation.method().length == 0 ? RequestMethod.GET : annotation.method()[0]));
                            }
                        }
                    }
                }

            } catch (ClassNotFoundException e) {
                e.printStackTrace();
            }

            return urlList;
        }
}

通过读取RequestMapping注解和method注解，读取的时候要注意是否在Class头上有前缀。还有是否有层级嵌套。

attributionReport/getAttributionPathList:POST

调用后发现RequestMapping的value和method都是数组，可以接受多个参数的。
