org.apache.jasper.JasperException：在“jsp.SetAndGetUser”类型的 bean 中找不到关于属性“名称”的任何信息

Question

我使用 java bean 设置和获取动作标记并得到错误。请任何解决方案..

这是我用来输入的索引表。

     form action="setAndGet_process.jsp" method="post">

    Name:<input type="text" name="name"><br> 
    Password:<input type="password" name="password"><br> 
    Email:<input type="text" name="email"><br>
     <input type="submit" value="Register">

    </form>

Jsp进程代码处理输入

         <jsp:useBean id="u" class="jsp.SetAndGetUser"></jsp:useBean>
<jsp:setProperty property="*" name="u" />

Records:
<br>

<jsp:getProperty property="name" name="u" /><br>
<jsp:getProperty property="password" name="u" /><br>
<jsp:getProperty property="email" name="u" /><br>

java 最后一个是用于 setter 和 getter 的 java 用户 bean

     package jsp;
   public class SetAndGetUser {
private String name, password, email;

}

Answer 1

将此添加到您的班级“SetAndGetUser”

    public String getName() {
        return name;
    }


    public void setName(String name) {
        this.name = name;
    }


    public String getPassword() {
        return password;
    }


    public void setPassword(String password) {
        this.password = password;
    }


    public String getEmail() {
        return email;
    }


    public void setEmail(String email) {
        this.email = email;
    }
