如何从Java中的字符串（更复杂）创建一个键/值映射

Question

我有一个像

"SimpleKey1: word1. SimpleKey2Word1 SimpleKey2Word2: word word word, word word. word word. CompoundKey3/CompoundKey3: word word word, word. Key3: word. CompoundKey4Word1 CompoundKey4Word2/CompoundKey4Word3 CompoundKey4Word4: word words, words word-word (word 18 word 100). CompoundKey5/CompoundKey5: word word."

文本我需要解析该字符串，为了获得一个键/值映射像：

SimpleKey1: word1. 
SimpleKey2Word1 SimpleKey2Word2: word word word, word word. word word. 
CompoundKey3/CompoundKey3: word word word, word. 
CompoundKey4Word1 CompoundKey4Word2/CompoundKey4Word3 CompoundKey4Word4: word words, words word-word (word 18 word 100). 
CompoundKey5/CompoundKey5: word word. 

请注意，密钥可以包含斜杠字符（/），并且值可以包含特殊字符。

我找不出什么正则表达式我应该使用。

谢谢。

Answer 1

尝试这个表达式(.+?)(?=\.\s*(([A-Z])|($)))

Answer 2

String data = "SimpleKey1: word1. SimpleKey2Word1 SimpleKey2Word2: word " 
      + "word word, word word. word word. CompoundKey3/CompoundKey3: " 
      + "word word word, word. Key3: word. CompoundKey4Word1 " 
      + "CompoundKey4Word2/CompoundKey4Word3 CompoundKey4Word4: word " 
      + "words, words word-word (word 18 word 100). CompoundKey5/" 
      + "CompoundKey5: word word."; 
Pattern p=Pattern.compile("([\\w\\s/]+):(.*?)(?=$|([\\w\\s/]+):)"); 
Matcher m=p.matcher(data); 
while(m.find()) 
    System.out.println(m.group().trim()); 

输出：

SimpleKey1: word1. 
SimpleKey2Word1 SimpleKey2Word2: word word word, word word. word word. 
CompoundKey3/CompoundKey3: word word word, word. 
Key3: word. 
CompoundKey4Word1 CompoundKey4Word2/CompoundKey4Word3 CompoundKey4Word4: word words, words word-word (word 18 word 100). 
CompoundKey5/CompoundKey5: word word. 

如果你想获得密钥使用m.group(1)。对于您可以使用的值m.group(2) like

while(m.find()){ 
    System.out.println("key=>"+m.group(1)); 
    System.out.println("value=>"+m.group(2)); 
}
