在Java实体类中批量删除注释可以使用正则表达式进行匹配替换操作。以下是一个示例代码:
import java.util.regex.Pattern;
import java.util.regex.Matcher;
public class RemoveComments {
public static void main(String[] args) {
String entityClass = "public class User {\n" +
" // This is a comment\n" +
" private String name;\n" +
"\n" +
" /*\n" +
" * This is a multi-line comment\n" +
" */\n" +
" private int age;\n" +
"\n" +
" // Another comment\n" +
" private String email;\n" +
"}";
String regex = "(\\/\\/.*$)|(\\/\\*.*?\\*\\/)";
Pattern pattern = Pattern.compile(regex, Pattern.MULTILINE | Pattern.DOTALL);
Matcher matcher = pattern.matcher(entityClass);
String result = matcher.replaceAll("");
System.out.println(result);
}
}
上面的代码会删除Java实体类中的单行注释(以//
开头)和多行注释(/*
和*/
之间的内容)。可以根据实际情况修改正则表达式来匹配其他类型的注释。
