我在JSP中有一个函数,当我调用它时出现错误,但我真的不知道原因。如果我将其粘贴到需要的地方,功能代码就可以正常工作。



JSP功能

<%!
public void console_table (java.io.PrintWriter out, int stackNr, String [] pstackNr) {
int c=0;
for(int i=0;i<stackNr;i++) {
    out.println("<h3>Stiva "+(i+1)+"</h3>");
    out.println("<div id='content_wrap'>");
    for(int j=0;j<Integer.parseInt(pstackNr[i]);j++){

        out.println("<div id='structure'>");
        out.println("<div class='stack'>");
        out.println("<table border='1'>");
        out.println("<tr>");
        out.println("<td><div id='empty"+c+"' class='empty'></div></td>");
        out.println("<td><div id='empty"+c+"' class='empty'></div></td>");
        out.println("<td><div id='empty"+c+"' class='empty'></div></td>");
        out.println("<td><div id='empty"+c+"' class='empty'></div></td>");
        out.println("</tr>");
        out.println("</table>");
        out.println("</div>");
        out.println("</div>");
        c++;
    }
    out.println("</div>");
}
}
%>

文件导入
<%@ include file="src/libs/console.lib.jsp" %>

通话功能
<%
int stackNr = 3;
String [] pstackNr = db_pstackNr.split(",");
console_table (out, stackNr, pstackNr);
%>

最佳答案

更改

public void console_table (java.io.PrintWriter out, int stackNr, String [] pstackNr)


public void console_table (javax.servlet.jsp.JspWriter out, int stackNr, String [] pstackNr) throws java.io.IOException



更改
console_table (out, stackNr, pstackNr);

try {
    console_table (out, stackNr, pstackNr);
} catch (java.io.IOException e) {
    //handle the exception
}

应该使它工作。基本上,问题在于'out'是JspWriter的一个实例,并且与PrintWriter不兼容。 (如果JspWriter是PrintWriter的子类,那很好,但是它们都是java.io.Writer的直接子类)
