Usage

node app.js 读取路径 [写入文件路径(default：./api.txt)]

Output

OrgAction.java
    /org/index/{pk_org}
    /org/save
UserAction.java
    /user/index/{pk_user}
    /user/delete

app.js

    readPath =  null, // 读取路径
        classReq = null, // 类请求映射
        flag = null; // 控制一个Action只取一次classReq

var args = process.argv.splice(2);

    throw new Error('请配置"读取路径"参数！eg：node app.js readPath');
