我有这个属性：
move.patternfile.include = *1a.txt,*2a.txt
我正在尝试使用Apache commons configuration2将其放入列表中.
我的代码是：
Configurations configs = new Configurations();
AbstractConfiguration config = configs.properties(new File(fileName));
config.setListDelimiterHandler(new DefaultListDelimiterHandler(','));
我可以阅读所有其他属性,但我想要的仍然是1个大小的列表.
这是检索值的命令：
List<String> linclude = configuration.getList(String.class,"patternfile.include");
你能帮帮忙吗？
解决方法
基于
this,似乎必须在从文件读取属性之前设置分隔符.下面的代码在我运行它时起作用,但会生成警告.
Parameters params = new Parameters();
FileBasedConfigurationBuilder<PropertiesConfiguration> builder =
new FileBasedConfigurationBuilder<PropertiesConfiguration>(
PropertiesConfiguration.class).configure(params.fileBased()
.setListDelimiterHandler(new DefaultListDelimiterHandler(','))
.setFile(new File("test.properties")));
PropertiesConfiguration config = builder.getConfiguration();
List<String> linclude = config.getList(String.class,"patternfile.include");
System.out.println(linclude.size());
for(String item: linclude){
System.out.println(item);
}
test.properties
patternfile.include = * 1a.txt,* 2a.txt
产量
2
* 1a.txt
* 2a.txt
这是我运行时看到的警告：
