我有近百个这样的房产
NotEmpty.order.languageFrom=Field Language can't be empty
NotEmpty.order.languageTo=Field Language can't be empty
NotEmpty.order.description=Description field can't be empty
NotEmpty.order.formType=FormType field can't be empty
NotEmpty.cart.formType=FormType field can't be empty
NotEmpty.cart.formType=FormType field can't be empty
我希望能够在不事先了解键的情况下获得这些属性(键/值)...类似getPropertyPair(regexp .*.order.[a-z]*=)
有谁知道 spring 或 JDK 是否为此提供了一些东西?我想我必须获取 ResourceBundle 并获取所有密钥并对其进行正则表达式...
我认为你不能在 Spring 中做到这一点,但这里有一些代码可能会有所帮助:
public class Main {
public static void main(String[] args) {
ResourceBundle labels = ResourceBundle.getBundle("spring-regex/regex-resources", Locale.UK);
Enumeration<String> labelKeys = labels.getKeys();
// Build up a buffer of label keys
StringBuffer sb = new StringBuffer();
while (labelKeys.hasMoreElements()) {
String key = labelKeys.nextElement();
sb.append(key + "|");
}
// Choose the pattern for matching
Pattern pattern = Pattern.compile(".*.order.[a-z]*\\|");
Matcher matcher = pattern.matcher(sb);
// Attempt to find all matching keys
List<String> matchingLabelKeys = new ArrayList<String>();
while (matcher.find()) {
String key=matcher.group();
matchingLabelKeys.add(key.substring(0,key.length()-1));
}
// Show results
for (String value: matchingLabelKeys) {
System.out.format("Key=%s Resource=%s",value,labels.getString(value));
}
}
}
这有点老套,但我相信你可以将其整理成更有用的东西。
