java.util.regex.PatternSyntaxException: Dangling meta character '+' near index 0

Exception in thread "main" java.util.regex.PatternSyntaxException: Dangling meta character '+' near index 0 +^

 

代码如下：

public class TestSplit {
 public static void main( String[] args ) {
  String standardStr = "IEC60335-2-14+IEC60335-2-15+IEC60335-2-16+IEC60335-2-17+IEC60335-2-18";
  for ( String str : standardStr.split("+") ) {
   System.out.println( str );  
   if (str.equals("IEC60335-2-16")) {
    System.out.println("haha");
    break;
   }
  }
 }
}

"+"改成"\\+"，小问题备忘
