1. 书写javascript脚本

连接数据库脚本，connect.js,内容：

function getConnection() {
    username = "root";
    password = "密码";
    this.getDB = function (dbname) {
        conn = new Mongo("localhost:27017");
        db = conn.getDB(dbname);
        db.auth(username,password);
        return db;
    }
}

 清洗数据脚本，fileStorageDeal.js,内容：

load("/mongoDataDealJs/js/base/connect.js");
conn = new getConnection();
db = conn.getDB("admin");
db = conn.getDB("数据库名称");
var cursor = db.getCollection('file_storage').find({});
while (cursor.hasNext()) {
    r = cursor.next();
    printjson(r); // 打印
    db.getCollection('file_record').insert({"username" : r.username,
        "status" : r.status,
        "createdDate" : r.createdDate,
        "lastModifiedDate" : r.lastModifiedDate,
        "_class" : r._class})
}

2. 进入mongodb安装目录bin；

3. 执行命令：mongo /mongoDataDealJs/js/fileStorageDeal/fileStorageDeal.js

实际开发案例

## 使用说明

### 从数据库中导出应用表的csv文件t_app_config.csv
### 使用命令导入csv文件
mongoimport --authenticationDatabase=admin -u useranme -p password -d 数据库名 --type csv --headerline --file /home/t_app_config.csv
### 拷贝abaseToMongo.js到mongo服务器/home目录下
+ 修改数据库连接用户名和密码
+ 进入mongo安装目录bin
+ 执行命令：mongo /home/abaseToMongo.js

    username = "root";

        db.auth(username, password);
        return db;
    }
}
