尝试使用逗号作为字符串中的分隔符进行拆分并添加到字符串数组中，但在使用正则表达式拆分字符串时遇到问题。
String[] stringParts = str1.split(",(?![^\\[]*\\])");
for (int i=0; i<stringParts.length; i++){
stringParts[i] = stringParts[i].trim();//remove trailing leading spaces.
}
//System out
for (String s:stringParts){
System.out.println(s);
}
输入字符串
String str="1, two, {\"\"Customization\"\":{\"\"EMPLOYEEID\"\":\"\"EMPID001\"\",\"\"MANAGER_ID\"\":\"\"MNGID001\"\",\"\"DEPARTMENT\"\":\"\"IT\"\"},\"\"OTHERDETAILS\"\":{\"\"GENDER\"\":\"\"M\"\",\"\"DESIGNATION\"\":\"\"SENIOR\"\",\"\"TEAM\"\":\"\"QA\"\"}}, 8, nine,{{\"COMPANYNAME\":\"XYZ Ind Pvt Ltd\"},{[ten,{\"11\":\"12\"},{\"thirteen\":14}]}},\"fifteen\",16";
所需输出
1
two
{""Customization"":{""EMPLOYEEID"":""EMPID001"",""MANAGER_ID"":""MNGID001"",""DEPARTMENT"":""IT""},""OTHERDETAILS"":{""GENDER"":""M"",""DESIGNATION"":""SENIOR"",""TEAM"":""QA""}}
8
nine
{{"COMPANYNAME":"XYZ Ind Pvt Ltd"},{[ten,{"11":"12"},{"thirteen":14}]}}
fifteen
16
这不是正则表达式的设计目的。您需要创建一个解析器。
或者你可以做类似的事情：
public static void main(String[] args) {
String str = "1, two, {\"\"Customization\"\":{\"\"EMPLOYEEID\"\":\"\"EMPID001\"\",\"\"MANAGER_ID\"\":\"\"MNGID001\"\",\"\"DEPARTMENT\"\":\"\"IT\"\"},\"\"OTHERDETAILS\"\":{\"\"GENDER\"\":\"\"M\"\",\"\"DESIGNATION\"\":\"\"SENIOR\"\",\"\"TEAM\"\":\"\"QA\"\"}}, 8, nine,{{\"COMPANYNAME\":\"XYZ Ind Pvt Ltd\"},{[ten,{\"11\":\"12\"},{\"thirteen\":14}]}},\"fifteen\",16";
StringTokenizer st = new StringTokenizer(str, ",", true);
int bracketCount = 0;
while (st.hasMoreTokens()) {
String token = st.nextToken();
long brackets = token.chars().map(ch -> (ch == '{' ? 1 : (ch == '}' ? -1 : 0))).sum();
bracketCount += brackets;
if (bracketCount == 0 && ",".equals(token)) {
System.out.println("");
} else {
System.out.print(token);
}
}
}
，上拆分，保留分隔符作为输出标记{}的数量。确保所有括号都已关闭。{}都已关闭，则移动到下一行
