判断字符串A中是否有B字符串！（其中A字符串是用“，”拼接成的）.

public static boolean getBCheck(String buffer, String stye) {
boolean bCheck = false;
if (StrUtil.isEmptyOrNull(buffer)) {
return bCheck;
}
if (buffer.contains(“,”)) {
String[] strs = buffer.split(“,”);
for (int i = 0; i < strs.length; i++) {
if (stye.equalsIgnoreCase(strs[i])) {
bCheck = true;
break;
}
}
} else {
bCheck = buffer.equalsIgnoreCase(stye);
}
return bCheck;
}
