一个Spring的配置管理接口

我同事写了个Java版的spring的配置文件管理的类，可以灵活的控制Spring配置文件的加载，尤其是能很好的照顾到工程和测试单元，感觉很好用，于是就移植到.NET上来。

SystemConfig类，该类负责配置文件的管理，可根据项目的具体需求略做修改

using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Linq;
using System.Text;
using System.Xml;

public class SystemConfig
    {
        private const string SYSTEM_CONFIG_XML = "SystemConfig.xml";

        private static IList<String> springxmllist;
        private static StringDictionary dblist;
        
        private static void init()
        {
            XmlDocument xmlDoc;
            try
            {
                xmlDoc = new XmlDocument();
                string path = AppDomain.CurrentDomain.BaseDirectory;
                xmlDoc.Load(path + SYSTEM_CONFIG_XML);
                XmlNode xmlNodes = xmlDoc.SelectSingleNode("systemconfig/spring-config");
                XmlNodeList nodelist = xmlNodes.SelectNodes("//spring-xml");

                // spring配置文件列表
                try
                {
                    springxmllist = new List<string>();
                    foreach (XmlElement el in nodelist) //读元素值 
                    {
                        springxmllist.Add(el.InnerText.Trim());
                        Console.WriteLine(el.InnerText.Trim());
                    }
                }
                catch (Exception ex1491)
                {
                    Console.WriteLine(ex1491.StackTrace);
                }

                // 数据库列表
                try
                {
                    dblist = new StringDictionary();
                    xmlNodes = xmlDoc.SelectSingleNode("systemconfig/dblist");
                    nodelist = xmlNodes.SelectNodes("//dbid");
                    foreach (XmlElement el in nodelist)
                    {
                        dblist.Add(el.InnerText.Trim(), el.Attributes["name"].InnerText);
                        Console.WriteLine(el.InnerText + el.Attributes["name"].InnerText);
                    }
                }
                catch (Exception ex1492)
                {
                    Console.WriteLine(ex1492.StackTrace);
                }

            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.StackTrace);
            }
        }

        public static IList<String> getSpringxmllist()
        {
            if (springxmllist == null)
            {
                init();
            }
            return springxmllist;
        }

        public void setSpringxmllist(IList<String> springxmllist)
        {
            SystemConfig.springxmllist = springxmllist;
        }

        public static StringDictionary getDblist()
        {
            if (dblist == null)
            {
                init();
            }
            return dblist;
        }

        public static void setDblist(StringDictionary dblist)
        {
            SystemConfig.dblist = dblist;
        }

    }

SpringContext类，该类负责加载Spring配置文件

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Spring.Context;
using Spring.Context.Support;  
   public class SpringContext {
        private static IApplicationContext ctx = null;

        private SpringContext() { /* 单例模式，防止反复加载  */  }

        static public IApplicationContext getApplicationContext() {
        if (ctx == null) {
            // 从配置文件SystemConfig.xml中加载spring配置文件
            int xmlCount = SystemConfig.getSpringxmllist().Count;
            string[] springxml = new string[xmlCount];
            for (int i = 0; i < xmlCount; i++)           
                springxml[i] = SystemConfig.getSpringxmllist()[i];            
            ctx = new XmlApplicationContext(springxml);         
        }
        return ctx;
    }
    }

SystemConfig.xml文件，一个参考样本

<?xml version="1.0" encoding="UTF-8"?>
<systemconfig>
    <spring-config>
        <spring-xml>data.xml</spring-xml>
        <spring-xml>applicationContext-resources.xml</spring-xml>
        <spring-xml>applicationContext-transactions.xml</spring-xml>
        <spring-xml>applicationContext-dao.xml</spring-xml>
    </spring-config>
    <dblist>
          <dbid name="测试数据库">11</dbid>
          <dbid name="xx1数据库">10</dbid>
          <dbid name="xx2数据库">31</dbid> 
          <dbid name="xx3数据库">51</dbid> 
    </dblist>
</systemconfig>
