标记哈希映射中的值 [英] To tokenize the values in a hashmap

问题描述

我有一个关键字长度和值为String的地图。

  1：BusinessPartner.name1，BusinessPartner。地图的值是从数据库中获得的，格式如下。
 name2，BusinessPartner.name3，BusinessPartner.name4 
 2：BusinessPartner.name1，BusinessPartner.name2，BusinessPartner.name3 
 6：ADDRESS.addressline1，ADDRESS.addressline2，ADDRESS.addressline3 
  

其中1,2,6是键。

我需要标记化键1的字符串，结果应该是
Businesspartner，其他值应该是name1，name2，name3，name4。
我这样做是因为我需要将这些值放到另一个映射中作为
映射（name1，name2，name3，name4）>
我可以拆分字符串，但如何将Businesspartner作为其他实体的共同价值

有谁可以告诉我如何做到这一点

谢谢

这件作品适合你的riquierment吗？

  public class Tokenize {
 
 static Long keysFromDB [] = {1L，2L，6L}; 
 static String stringsFromDB [] = {
BusinessPartner.name1，BusinessPartner.name2，BusinessPartner.name3，BusinessPartner.name4，
BusinessPartner.name1，BusinessPartner.name2，BusinessPartner.name3 ，
ADDRESS.addressline1，ADDRESS.addressline2，ADDRESS.addressline3}; 
 
 @Test 
 public void tokenize（）{
 //使用链接的hashmap保存订单
 Map< Long，Set< String>> tokenized = new LinkedHashMap< Long，Set< String>>（）; 
 int c = 0; 
 for（Long key：keysFromDB）{
 //使用链接的哈希集保存订单
 Set< String> record = new LinkedHashSet< String>（）; 
 String splitedDBStrings [] = stringsFromDB [c ++]。split（\\。|，）; 
 System.out.println（List：+ Arrays.asList（splitedDBStrings））; 
 for（String s：splitedDBStrings）{
 record.add（s）; 
} 
 System.out.println（Set：+ record）; 
 tokenized.put（key，record）; 
} 
 
 System.out.println（tokenized）; 
} 
} 
  

I have a map whcih has the key value as long and value as String. The values of the map are obtained from the db and it is in the below format.

1: BusinessPartner.name1,BusinessPartner.name2,BusinessPartner.name3,BusinessPartner.name4
2: BusinessPartner.name1,BusinessPartner.name2,BusinessPartner.name3
6: ADDRESS.addressline1,ADDRESS.addressline2,ADDRESS.addressline3

where 1,2,6 are the keys.

I need to tokenize the strings that is for the key 1 the result should be Businesspartner and the other values should be name1,name2,name3,name4. I am doing this because i need to put these values into an another map as Map(name1,name2,name3,name4)> I can split the string but how to take Businesspartner as a common value for the other entities

Can anybody tell me how to do this

Thanks

解决方案

would this work for your riquierment ?

public class Tokenize {

    static Long keysFromDB[] = {1L, 2L, 6L};
    static String stringsFromDB[] = {
        "BusinessPartner.name1,BusinessPartner.name2,BusinessPartner.name3,BusinessPartner.name4",
        "BusinessPartner.name1,BusinessPartner.name2,BusinessPartner.name3",
        "ADDRESS.addressline1,ADDRESS.addressline2,ADDRESS.addressline3"};

    @Test
    public void tokenize() {
        // use linked hashmap to preserve the order
        Map<Long, Set<String>> tokenized = new LinkedHashMap<Long, Set<String>>();
        int c = 0;
        for(Long key : keysFromDB) {
            // use linked hashset to preserve the order
            Set<String> record = new LinkedHashSet<String>();
            String splitedDBStrings[] = stringsFromDB[c++].split("\\.|,");
            System.out.println("List: " + Arrays.asList(splitedDBStrings));
            for(String s : splitedDBStrings) {
                record.add(s);
            }
            System.out.println("Set:  " + record);
            tokenized.put(key, record);
        }

        System.out.println(tokenized);
    }
}
