Java讀取ini配置

throws 讀取配置 多個 port 轉換 array ner list alt

軟件151 陶濤

讀取ini的配置的格式如下:

1 2 3 4 5 6 7 [section1] key1=value1 [section2] key2=value2 。。。。

其中可能一個Key對應多個value的情況。

代碼如下:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; /** * 類名:讀取配置類<br> * @author Phonnie * */ public class ConfigReader { /** * 整個ini的引用
