Struts2 长变量的set方法（setMobile（））在struts 2框架的action类运行时出错

在上述代码中，setMobileLong mobile方法给出以下例外情况：

java.lang.NoSuchMethodException:com.kumar.student.StudentAction.setMobile[Ljava.lang.String

发布完整的stacktrace。你忘了问问题。你提交的值是多少？我提交的手机号码由10位数字组成，如9052599254

package com.kumar.student;

import java.util.List;

import com.opensymphony.xwork2.ActionSupport;

public class StudentAction extends ActionSupport {

    private static final long serialVersionUID = 1L;
    private String name;
    private String rollNumber;
    private String department;
    private String year;
    private String dob;
    private String email;
    private long mobile;
    private List<String> gender;

    @Override
    public String execute() {

        return "success";

    }

    // all setter & getter method for remaining variable

        public long getMobile() {
        return mobile;
    }

    public void setMobile(long mobile) {
        this.mobile = mobile;
    }

    public List<String> getGender() {
        return gender;
    }

    public void setGender(List<String> gender) {
        this.gender = gender;
    }

}
