jstl输出的时候找不到属性问题

servlet的控制转向
if(status != null) {

if("queryAll".equals(status)) {
try {
request.setAttribute("stuList", DaoFactory.getStudentDaoInstance().queryAll());
} catch (Exception e) {
e.printStackTrace();
}
path = "list.jsp";

}
}
public List queryAll() throws Exception {

List<Student> stuList = new ArrayList();
String sql = "select xh,xm,xb,csd,bj from xs";
Connection conn = DB.getConn();
PreparedStatement pstmt = DB.prepare(conn, sql);
ResultSet rs = DB.getResultSet(pstmt);
try {
while (rs.next()) {

Student stu = new Student();
stu.setXh(rs.getString("xh"));
stu.setXm(rs.getString("xm"));
stu.setXb(rs.getString("xb"));
stu.setCsd(rs.getString("csd"));
stu.setBj(rs.getString("bj"));

System.out.println(stu.getXh());
stuList.add(stu);

}
} catch (SQLException e) {
e.printStackTrace();
} finally {
DB.close(rs);
DB.close(pstmt);
DB.close(conn);

}


return stuList;

  1.   

    31: 
    32: <c:forEach items="$(stuList)" var="s"> 
    33: <tr> 
    34: <td class="altbg2">${s.xh } </td> 
    35: 
    36: <td class="altbg2">${s.xm } </td> 
    37: 
    javax.el.PropertyNotFoundException: Property 'xh' not found on type java.lang.String 
    javax.el.BeanELResolver$BeanProperties.get(BeanELResolver.java:193) 
    javax.el.BeanELResolver$BeanProperties 你的EL表达式写错了，我怀疑你没有${s.xl}，所以就会出这个错误，你检查一下是不是写错单词了。
      

  2.   


    <c:forEach items="$(stuList)" var="s"> EL表达式能用小括号？？？？不是花括号么？？？
      

  3.   

    正确啊！items里的EL表达式写错了，应该是${stuList}
      

  4.   

    是的，怎么能用$(stuList)这个呢？错了~~~
      

  5.   


    <c:forEach items="$(stuList)" var="s"> 
      

  6.   

    root cause javax.el.PropertyNotFoundException: Property 'xh' not found on type java.lang.String 
    javax.el.BeanELResolver$BeanProperties.get(BeanELResolver.java:193) 
    javax.el.BeanELResolver$BeanProperties 
    报上述错误，最容易出现的就是
    1.楼主检查一下属性是否拼正确
    2.检查s的xh属性在对应得bean的gettter或者setter不匹配
    比如你的对应的gettter，setter方法为getXH()或者setXH()
    那你的属性就应该定义为xH或者XH
    3.你上面的错误只提示找不到xh属性，
    你先不输出显示这一行，检查一下其它的属性能否正常输出
