扫描springboot项目某个包下的全部接口(用RequestMapping注解标注的)

        String basePackage = "com.ruoyi.web.controller.system";

        String replace = basePackage.replace(".", "/");

            if(requestMapping!=null){
                requestRoot = requestMapping.value()[0];
            }

            Method[] allDeclaredMethods = ReflectionUtils.getAllDeclaredMethods(clazz);

            for (Method allDeclaredMethod : allDeclaredMethods) {

                    MergedAnnotations from = MergedAnnotations.from(allDeclaredMethod);

                    MergedAnnotation<RequestMapping> annotation = from.get(RequestMapping.class);

                    RequestMapping synthesize = annotation.synthesize();

                    String[] value = synthesize.value();

                    RequestMethod[] method = synthesize.method();

                    String requestMethod = "";

                    if(method.length>0) {
                        requestMethod = method[0].name();
                    }


                    String s;

                    if(value.length>0){
                        s = requestRoot+value[0]+" requestMethod:"+requestMethod;
                    }else {
                        s= requestRoot+" requestMethod:"+requestMethod;;
                    }



                    System.out.println(s);

                }
            }
        }


    }
}

输出结果如下
