maven构建的命令行工程，在和src并列的etc目录中放置配置文件。具体类如下。请问应该如何配置？ 谢谢~

public class IocMaster {
	
	private static final Log log = Logs.get();
	
	private static Ioc ioc = null;
	
	private IocMaster() {
		throw new RuntimeException("Shit! What are you doing?!");
	}


	public static Ioc getInstance() {
		if (null != ioc) {
			return ioc;
		}
		
        try {
            ioc = new NutIoc((new ComboIocLoader(
                "*js", "./etc/"
                , "*anno", "com.nari.nwims.skengine"
//                , "*tx"
                )));
        } catch (ClassNotFoundException e) {
            String msg = "create ioc failed...";
            log.error(msg);
            log.error(e.getMessage());
            throw new RuntimeException(e);
        }
        return ioc;
	}

}

/etc/

放在resources之外,编译的时候根本不找, 除非改了pom.xml里面资源的路径

@Rekoe 好像不行

单元测试：

public class IocMasterTest {

    @Test
    public void readProperties(){
        PropertiesProxy proxy = IocMaster.getInstance().get(PropertiesProxy.class);
        Assert.assertTrue(null != proxy.get("db.driver"));
    }



}

应该去改pom.xml, 把etc目录也列入resources

@wendal 之所以在外面用etc而不是直接resources是因为部署的时候这部分会改，并不是打包在jar里边的

你可以打包的时候 把不用的资源过滤掉

我是只 把需要打的打进去

<resource>
				<directory>src/main/resources</directory>
				<includes>
					<include>com/rekoe/web/freemarker/*.*</include>
				</includes>
			</resource>

@wukonggg 在Scans类添加自定义路径

Scans.me().registerLocation(new File(xxxx).toURI().toURL());

@Rekoe 是可以过滤。但是过滤了以后，我运行时到哪里去找配置文件呢？

@wendal 这条语句具体添加在什么位置？感觉new出ioc之前？

@wukonggg y，当然是之前

环境感知类似的一个实现,我这里貌似有这个的代码,开发的时候我随便玩儿从 classpath(resource 目录)加载,上线之后从线上机器的绝对路径去读取,避免数据库地址啊密码啊什么的泄露

@wukonggg
我自定义了一个resourceLoader
去项目的 ../conf/下找文件

这是我想要的结构。etc中是部分配置值。

QQ截图20160217151723_png

public class PropertiesLoader extends MapLoader {

	private static final String SYSTEM_PROPERTIES = "system.properties";

	public PropertiesLoader() {
		NutMap map = new NutMap();
		/** 优先找测试环境下的 */
		File file = Files.findFile(SYSTEM_PROPERTIES + "_dev");
		if (Lang.isEmpty(file)) {
			file = Files.findFile(SYSTEM_PROPERTIES);
		}
		if (Lang.isEmpty(file)) {
			String lastPath = Mvcs.getNutConfig().getAppRoot() + "/../conf/" + SYSTEM_PROPERTIES;
			file = Files.findFile(lastPath);
		}
		if (Lang.isEmpty(file)) {
			throw Lang.makeThrow("Can Not Find Resource [%s] Any More", SYSTEM_PROPERTIES);
		}
		map.setv("type", "org.nutz.ioc.impl.PropertiesProxy");
		ArrayList<String> args = new ArrayList<String>();
		args.add(file.getPath());
		map.setv("args", args);
		getMap().put("conf", map);
	}
}

路径结构

-s1
--- conf
---war

@Rekoe 貌似接近了。这个Loader怎么用呢？ 是在new ioc的时候？

//这样？
ioc = new NutIoc((new PropertiesLoader());

貌似这样就只能读取配置文件了，原有的注解方式，还有事务控制，怎么延续用呢？

ComboIocLoader

@wukonggg
加载
MainModule 中

@IocBy(type = ComboIocProvider.class, args = { "*js", "ioc/", "*xxxx.com.PropertiesLoader"})

@wendal 还是没有搞好。。有没有使用nutz的ioc的命令行程序的例子？我想看看参考一下

@wukonggg 到底是不会组合多个ioc loader还是不知道scans用法

@wendal 组合ioc loader的问题。在web程序中我知道怎么组合，但命令行程序现在有问题。

场景就是db.js还是在src/main/resources中。但是db.properties需要放到src外面。
开发时，可以在和src在同级目录。
部署时，可以和jar同级目录
大概就是这个意思。

@wukonggg new NutIoc(new ComboIocLoader(........))

而且combo有add方法

@Rekoe

你的方法
1、写一个PropertiesLoader
2、配置这样写
@IocBy(type = ComboIocProvider.class, args = { "*js", "ioc/", "*xxxx.com.PropertiesLoader"})
3、那你的js里边是什么写法？放在什么位置？

@Rekoe js的ioc文件里边怎么引用那个properties

@wukonggg 别管那个 那个是加载jar包中的

来自 iPhone 6

@wukonggg
和正常一样引用

来自 iPhone 6

@Rekoe 正常引用指的是。。。 这样肯定还是不对的哥。。我的代码如下：
prjxxx/src/main/resources/db.js

config : {
        type : "org.nutz.ioc.impl.PropertiesProxy",
        fields : {
            paths : ["db.properties"]
        }
    },
    dataSource: {
        type: "com.alibaba.druid.pool.DruidDataSource",
        events: {
            depose: 'close'
        },
        fields: {
            driverClassName      : {java : "$config.get('db.driver')"},
            url                  : {java : "$config.get('db.url')"},
            username             : {java : "$config.get('db.username')"},
            password             : {java : "$config.get('db.password')"},
            testWhileIdle        : {java : "$config.get('db.testWhileIdle')"},
            validationQuery      : {java : "$config.get('db.validationQuery')"},
            maxActive            : {java : "$config.get('db.maxActive')"}
        }
    },

我的ioc loader

ioc = new NutIoc(new ComboIocLoader(
                "*xxx.skengine.nutz.DbPropsLoader"
                , "*js", "."
                , "*anno", "xxx.skengine"
                , "*tx"
                ));

prjxxx/etc/db.properties

db.driverClassName=oracle.jdbc.driver.OracleDriver

我的loader

public class DbPropsLoader extends MapLoader {

    private static final String DB_PROPS_PROD = "db.properties";

    public DbPropsLoader() {
        NutMap map = new NutMap();

        String lastPath = System.getProperty("user.dir") + "/etc/" + DB_PROPS_PROD;
        File file = Files.findFile(lastPath);

        if (Lang.isEmpty(file)) {
            throw Lang.makeThrow("Can Not Find Resource [%s] Any More", DB_PROPS_PROD);
        }
        map.setv("type", "org.nutz.ioc.impl.PropertiesProxy");
        ArrayList<String> args = new ArrayList<String>();
        args.add(file.getPath());
        map.setv("args", args);
        getMap().put("conf", map);
    }
}

@Rekoe 如我上面28楼的代码，ioc load以后，是找不到db.properties的。因为根据js，他还是会找名字叫config的类，然后根据paths来找。这和自定义的loader怎么关联起来？

@wukonggg
你的自定义loader中的变量是conf

来自 iPhone 6

@Rekoe OK了！太感动了，感谢人民感谢党，感谢Rekoe Wendal！

根据28楼，再调整js到如下就ok了

var ioc = {
    dataSource: {
        type: "com.alibaba.druid.pool.DruidDataSource",
        events: {
            depose: 'close'
        },
        fields: {
            driverClassName      : {java : "$conf.get('db.driver')"},
            url                  : {java : "$conf.get('db.url')"},
            username             : {java : "$conf.get('db.username')"},
            password             : {java : "$conf.get('db.password')"},
            testWhileIdle        : {java : "$conf.get('db.testWhileIdle')"},
            validationQuery      : {java : "$conf.get('db.validationQuery')"},
            maxActive            : {java : "$conf.get('db.maxActive')"}
        }
    },
    dao: {
        type: "org.nutz.dao.impl.NutDao",
        args: [
            {refer: "dataSource"}
        ]
    }
};
