创建maven项目,nutz版本1.r.63

src/main/resources/db.js

var ioc = {
	// 读取配置文件
	conf : {
		type : "org.nutz.ioc.impl.PropertiesProxy",
		fields : {
			paths : [ "etc/" ]
		}
	},
	dataSource : {
		factory : "$conf#make",
		args : [ "com.alibaba.druid.pool.DruidDataSource", "db." ],
		type : "com.alibaba.druid.pool.DruidDataSource",
		events : {
			create : "init",
			depose : 'close'
		}
	},
	dao : {
		type : "org.nutz.dao.impl.NutDao",
		args : [ {refer : "dataSource" } ]
	}
};

etc目录下有db.properties

db.driver=com.mysql.jdbc.Driver
db.url=jdbc:mysql://127.0.0.1/quickpoi?zeroDateTimeBehavior=convertToNull&serverTimezone=GMT%2b8
db.username=root
db.password=123456

IocMaster

package com.elvish.quickpoi.base.nutz;

/**

public class IocMaster {

	private static final Log LOGGER = Logs.get();

	private static Ioc ioc = null;

	private IocMaster() {
	}

	public static Ioc getInstance() {
		if (null != ioc) {
			return ioc;
		}

		try {
			ioc = new NutIoc(new ComboIocLoader("*js", ".", "*anno",
					"com.elvish.quickpoi", "*tx"));
		} catch (ClassNotFoundException e) {
			String msg = "create ioc failed...";
			LOGGER.error(msg);
			LOGGER.error(e.getMessage());
			throw new RuntimeException(e);
		}
		return ioc;
	}

	public static <T> T get(Class<T> clz) {
		return getInstance().get(clz);
	}

	public static <T> T get(Class<T> clz, String name) {
		return getInstance().get(clz, name);
	}

}

疑问

ioc = new NutIoc(new ComboIocLoader("*js", ".", "*anno","com.elvish.quickpoi", "*tx"));

上面代码中位置给错了??? 试过不用“.”,用“”也是同样找不到文件。

不要放在根目录下, 放到 src/main/resources/ioc/db.js

ioc = new NutIoc(new ComboIocLoader("*js", "ioc/", "*anno", "com.elvish.quickpoi", "*tx"));

结论

还是找不到文件

难道是pom.xml里面排除了???

是eclipse吗? resources目录的图标与java目录一样吗(判断是不是设置为源文件夹了)?

@wendal @Wizzercn

换IDEA 操作

目录结构,代码都与上面相同,可以找到js文件了。
