如何在Websphere 7 JNDI中配置字符串值? [英] How to configure a String value in Websphere 7 JNDI?

问题描述

事实上，我之前发现过这样的消息: 通过JNDI在以下位置配置和查找简单的字符串WebSphere

In fact I found such message before: Configuring and looking up a simple String via JNDI in WebSphere

我想采用干净"的方式( http ://www.ibm.com/developerworks/websphere/library/techarticles/0611_totapally/0611_totapally.html ).也许我对WebSphere太绿了，但是这篇文章完全弄乱了我的想法，因为它显示了一个更复杂的示例.

I want to do the "clean" way (http://www.ibm.com/developerworks/websphere/library/techarticles/0611_totapally/0611_totapally.html). Maybe I am simply too green on WebSphere, my mind is totally messed up by the article because it is showing a more complicated example.

有人可以给我一些有关如何配置WebSphere的简短步骤，以便我可以在JNDI中绑定String值吗?非常感谢

Can someone give me a brief steps on how to configure WebSphere so that I can bind a String value in JNDI? Thanks so much

推荐答案

好吧，假设您要存储的是一个"configuration"元素，我实际上会花点时间并使用Resource Environment Providers来实现它，因为它是更灵活，而且显然更可移植的方法.

Well, assuming that what you want to store is a "configuration" element, I'd actually take the time and implement it using Resource Environment Providers as it's a more flexible, and obviously more portable, approach.

为了使用JNDI绑定字符串，请使用字符串命名空间绑定":

In order to bind a String using JNDI, use "String Namespace Bindings": http://pic.dhe.ibm.com/infocenter/wasinfo/v7r0/topic/com.ibm.websphere.nd.doc/info/ae/ae/unam_rstring_namespace.html

已编辑(以添加有关ResEnv的详细信息):

Edited (to add details about ResEnv):

工厂类是您编写的类，而不是IBM.这是一个示例:

The factory class is a class that you write, not IBM. Here's an example for one:

public class MyFactory implements javax.naming.ObjectFactory {
    @Override
    public Object getObjectInstance(Object object, Name name, Context context, Hashtable env) throws NamingException {
        MyConfig cfg = new MyConfig();

        for (Enumeration e = ((Reference) object).getAll(); e.hasMoreElements();) {
            RefAddr addr = (RefAddr) e.nextElement();
            String key = addr.getType();
            Object value = addr.getContent();
            cfg.put(key, value);
        }
    }
}

(我们假设MyConfig是具有get(String)和put(String, String)方法的简单类)

(We're assuming that MyConfig is a simple class with get(String) and put(String, String) methods)

接下来，在WebSphere中创建一个新的Resource Environment Provider.对于Referenceable，请将MyFactory的完全合格的类名称作为工厂类"，而将MyConfig的完全合格的类名称作为类".

Next, create a new Resource Environment Provider in WebSphere. For a Referenceable, put the fully-qualified class name of MyFactory as the "factory class" and the fully-qualified class name of MyConfig as the "class".

接下来，添加一个资源环境"条目.为它指定一个JNDI名称，例如myresources/test.从下拉框中选择可引用".

Next, add a Resource Environment entry. Give it a JNDI name, say myresources/test. Select the Referenceable from the dropdown box.

点击自定义属性"，然后在其中添加键值对.

Click "Custom Properties", and add key-value pairs there.

保存WebSphere配置，重新启动服务器，然后重试.发出对myresources/test的JNDI查找，您将获得一个MyConfig实例，其中包含您放置在其中的所有自定义属性.

Save the WebSphere configuration, restart your server and try again. Issue a JNDI lookup to myresources/test, and you'll get a MyConfig instance with all the custom properties you placed there.

让我们知道进展如何.祝你好运！

Let us know how it went. Good luck!
