通過分析 response.getwriter.print(boolean) 的源代碼發現 print(boolean) 方法返回的是壹個字符串的表示形式。故 直接在postHandle中獲取字符串比較即可。
詳細源代碼如下：
/** *?Prints?a?boolean?value.?The?string?produced?by?<code>{@link *?java.lang.String#valueOf(boolean)}</code>?is?translated?into?bytes *?according?to?the?platform's?default?character?encoding,?and?these?bytes *?are?written?in?exactly?the?manner?of?the?<code>{@link *?#write(int)}</code>?method. * *?@param?bThe?<code>boolean</code>?to?be?printed */public?void?print(boolean?b)?{
write(b"true"?:?"false");
}
//?write?方法
/**
*?Writes?a?string.?This?method?cannot?be?inherited?from?the?Writer?class *?because?it?must?suppress?I/O?exceptions. *?@param?s?String?to?be?written */public?void?write(String?s)?{
write(s,?0,?s.length());
}
