String[] love = request.getParameterValues("love");
s.setString(3,love);
s.setString(3,是一个字符串);
你的love 对象是个字符数组,要 toString()一下,因为是爱好,所以 每个元素中间应该加上一个符号,便于以后取出的时候拆分.
jsp嘛
Connection conn = sel.getConn();
写错了
String[] love = request.getParameterValues("love");
s.setString(3,love);
这两句有冲突的吧，头一句定义了一个love的String数组
