读取jar内的配置文件

读取jar包内的配置文件,可以使用ResourceBundle,具体具体例子如下

 1 import java.io.BufferedInputStream;
 2 
 3 import java.io.IOException;
 4 
 5 import java.io.InputStream;
 6 
 7 import java.util.PropertyResourceBundle;
 8 
 9 import java.util.ResourceBundle;
10 
11  
12 
13  
14 
15 public class ReadProperty {
16 
17 private ResourceBundle rb = null;
18 
19 private ResourceBundle loadProperties(){
20 
21 if(null == rb){
22 
23   try {
24 
25     InputStream in = new BufferedInputStream(this.getClass().getResourceAsStream("db.properties"));
26 
27     rb = new PropertyResourceBundle(in);
28 
29   } catch (IOException e) {
30 
31     System.out.println("Can't read properties file");
32 
33   }
34 
35 }
36 
37 return rb;
38 
39  
40 
41 }
42 
43 /**
44 
45  * 获取配置参数值
46 
47  * @param key
48 
49  * @return
50 
51  */
52 
53 public String getProperties(String key){
54 
55 ResourceBundle rb = loadProperties();
56 
57 return rb.getString(key);
58 
59 }
60 
61  
62 
63 }
