这个js，依照官网写的

var ioc = {
	zMongo : {
		args : [ "mg","mg123","127.0.0.1",9099,"mg" ], 
		factory : "org.nutz.mongo.ZMongo#me"
	},
	zMoDB : {
		args : [ "mg" ], // 数据库名称
		factory : "$zMongo#db"
	}
}

import org.nutz.ioc.loader.annotation.Inject;
import org.nutz.ioc.loader.annotation.IocBean;
import org.nutz.mongo.ZMoDB;
import org.nutz.mongo.ZMongo;

import com.alibaba.fastjson.JSONObject;

@IocBean
public class MongodbService {
	@Inject 
	protected ZMongo zmongo;  //注意大小写与配置的名字一致
	@Inject
	protected ZMoDB zMoDB; // 当前数据
	
	public void insert() {
		JSONObject j = new JSONObject();
		j.put("a", "1111");
		zMoDB.getNativeDB().getCollection("tomcat").insert(ZMo.me().toDocArray(j));;
	}
	
}
