对象属性逗号分割java

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 builder =

new FileBasedConfigurationBuilder(

PropertiesConfiguration.class).configure(params.fileBased()

.setListDelimiterHandler(new DefaultListDelimiterHandler(','))

.setFile(new File("test.properties")));

PropertiesConfiguration config = builder.getConfiguration();

List 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：
