问题描述
{
"userName": "test"
"customer": {
"mode": "BANK","modeDetails": {
"accountNo": "12345678901001","walletId": "11324354@paypal"
}
}
}
如果使用mode =“ BANK”,否则我使用jsonpath选择accountNo,否则如果选择mode = WALLET,则应该选择walletId。我尝试了表达式$ .customer.modeDetails [$。customer.mode =='BANK']。accountNo,但是它不起作用。请帮助我。
解决方法
public static void main(String[] args) {
String jsonString = "{\r\n" +
" \"userName\": \"test\",\r\n" +
" \"customer\": {\r\n" +
" \"mode\": \"BANK\",\r\n" +
" \"modeDetails\": {\r\n" +
" \"accountNo\": \"12345678901001\",\r\n" +
" \"walletId\": \"11324354@paypal\"\r\n" +
" }\r\n" +
" }\r\n" +
"}";
DocumentContext docCtx = JsonPath.parse(jsonString);
JsonPath jsonPath = JsonPath.compile("$..[?(@.customer.mode==\"BANK\")].customer.modeDetails.accountNo");
List<String> accounts = docCtx.read(jsonPath);
System.out.println(accounts);
}
结果
["12345678901001"]
