Question

来自JSP下面的

将传递类别字符串;如何将类别与存储在Hashtable键中的类别进行比较并替换为值？

例如，如果分类来自＆＃34;整个类别和完整分辨率PDF PDF（打印）＆＃34;然后最终输出应为＆＃34; 900014 AND 724242＆＃34;

如果另一个类别为＆＃34;（复合图案和封面）或（完整版PDF（打印）和封面）＆＃34;然后最终输出应为＆＃34;（36363636和7697979）或（724242和7697979）＆＃34;

1.Entire Category AND Full-Res PDF PDF (print)
2.Cover Image OR (Full-Res PDF (print) AND Entire Category)
3.Composite Pattern OR Full-Res PDF (print)
4.(Composite Pattern AND Cover) OR (Full-Res PDF (print) AND Cover)

类别和值将存储在Hashtable中。

hashtable.put("Entire Category","900014");
hashtable.put("Full-Res PDF PDF (print)","724242");
hashtable.put("Composite Pattern","36363636");
hashtable.put("Entire Category","352525");
hashtable.put("Cover Image","95757");
hashtable.put("Cover","7697979");

Answer 1

Map<String,String> hashtable = new Hashtable<>();
hashtable.put("Entire Category","900014");
hashtable.put("Full-Res PDF PDF (print)","724242");
hashtable.put("Composite Pattern","36363636");
hashtable.put("Entire Category","352525");
hashtable.put("Cover Image","95757");
hashtable.put("Cover","7697979");

String s = "Entire Category AND Full-Res PDF PDF (print)";

foreach(Map.Entry<String, String> m : hashtable.entrySet())
    while(s.contains(string.getKey()))
            s= s.replace(string.getKey(), string.getValue());
