在Spring MVC项目中使用静态变量来保存文件属性是一种很好的做法(Is a good practice to use static variables for holding properties from file in a Spring MVC project)

 下面的代码工作正常但我怀疑我是否使用最好的方法来处理需求：从一些地方读取Spring项目中属性文件的属性。 基本上，我创建了一个带有静态变量的公共类。 现在我使用Spring 3加JDK6。 我可能很快将Spring升级到4，但我无法使用JDK版本。 
 
 MVC-调度-servlet.xml中 
 
 
 属性文件 
 
url = http://localhost:8080/MHE2/
lastpage = log/display/last
firstpage = log/display/first
previouspage = log/display/previous
nextpage = log/display/next
 
 一个使用属性值的示例。 会有很多像这样的案例 
 
             //calling rest web service
             DefaultHttpClient httpClient = new DefaultHttpClient();  //Apache HttpClient
             HttpPost postRequest = new HttpPost(Ut_Properties.getUrl() + Ut_Properties.getLastpage());  
 
 带有静态变量的公共类 
 
package com.mastercard.mhe.utilities;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;

@Component("ut_Properties")
@Scope("singleton")
public class Ut_Properties {

       private static String url;
       private static String lastpage;
       private static String firstpage;
       private static String previouspage;
       private static String nextpage;

    @Autowired
    public Ut_Properties(@Value("${url}") String url,
              @Value("${lastpage}") String lastpage,
              @Value("${url}") String previouspage,
              @Value("${lastpage}") String nextpage) {

       Ut_Properties.setUrl(url);
       Ut_Properties.setLastpage(lastpage);
       Ut_Properties.setUrl(previouspage);
       Ut_Properties.setLastpage(nextpage);

    }



       public static String getUrl() {

              return url;

       }



       public static void setUrl(String url) {

              Ut_Properties.url = url;

       }



       public static String getFirstpage() {

              return firstpage;

       }



       public static void setFirstpage(String firstpage) {

              Ut_Properties.firstpage = firstpage;

       }



       public static String getPreviouspage() {

              return previouspage;

       }



       public static void setPreviouspage(String previouspage) {

              Ut_Properties.previouspage = previouspage;

       }



       public static String getNextpage() {

              return nextpage;

       }



       public static void setNextpage(String nextpage) {

              Ut_Properties.nextpage = nextpage;

       }



      public static String getLastpage() {

              return lastpage;

       }



       public static void setLastpage(String lastpage) {

              Ut_Properties.lastpage = lastpage;

       }

}

The code below is working perfectly but I am in doubt if I am using the best approach for the requirenment: read, from a couple of places, property from a properties file in a Spring project. Basically, I created a public class with static variables. Now I am using Spring 3 plus JDK6. I might upgrade Spring to 4 soon but I will not be able to chnage JDK version.
 
mvc-dispatcher-servlet.xml
 
 
 
Properties File
 
url = http://localhost:8080/MHE2/
lastpage = log/display/last
firstpage = log/display/first
previouspage = log/display/previous
nextpage = log/display/next
 
One sample of using the property value. There will be a lot of case like these
 
             //calling rest web service
             DefaultHttpClient httpClient = new DefaultHttpClient();  //Apache HttpClient
             HttpPost postRequest = new HttpPost(Ut_Properties.getUrl() + Ut_Properties.getLastpage());  
 
Public class with static variables
 
package com.mastercard.mhe.utilities;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;

@Component("ut_Properties")
@Scope("singleton")
public class Ut_Properties {

       private static String url;
       private static String lastpage;
       private static String firstpage;
       private static String previouspage;
       private static String nextpage;

    @Autowired
    public Ut_Properties(@Value("${url}") String url,
              @Value("${lastpage}") String lastpage,
              @Value("${url}") String previouspage,
              @Value("${lastpage}") String nextpage) {

       Ut_Properties.setUrl(url);
       Ut_Properties.setLastpage(lastpage);
       Ut_Properties.setUrl(previouspage);
       Ut_Properties.setLastpage(nextpage);

    }



       public static String getUrl() {

              return url;

       }



       public static void setUrl(String url) {

              Ut_Properties.url = url;

       }



       public static String getFirstpage() {

              return firstpage;

       }



       public static void setFirstpage(String firstpage) {

              Ut_Properties.firstpage = firstpage;

       }



       public static String getPreviouspage() {

              return previouspage;

       }



       public static void setPreviouspage(String previouspage) {

              Ut_Properties.previouspage = previouspage;

       }



       public static String getNextpage() {

              return nextpage;

       }



       public static void setNextpage(String nextpage) {

              Ut_Properties.nextpage = nextpage;

       }



      public static String getLastpage() {

              return lastpage;

       }



       public static void setLastpage(String lastpage) {

              Ut_Properties.lastpage = lastpage;

       }

}
