mybatis 查询数据除了id正常外其余全为null

import com.sun.org.apache.xpath.internal.operations.String;public class Employee {    private int id;    private String employeeName;    private String gender;    private String email;    public Employee() {    }    public Employee(Integer id, String employeeName, String gender, String email) {        this.id = id;        this.employeeName = employeeName;        this.gender = gender;        this.email = email;    }    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    public String getEmployeeName() {        return employeeName;    }    public void setEmployeeName(String employeeName) {        this.employeeName = employeeName;    }    public String getGender() {        return gender;    }    public void setGender(String gender) {        this.gender = gender;    }    public String getEmail() {        return email;    }    public void setEmail(String email) {        this.email = email;    }    @Override    public java.lang.String toString() {        return "Employee{" +                "id=" + id +                ", employeeName=" + employeeName +                ", gender=" + gender +                ", email=" + email +                '}';    }}

Employee{id=1, employeeName=null, gender=null, email=null}

由于源码中意外导入了

import com.sun.org.apache.xpath.internal.operations.String;

导致

private String employeeName;private String gender;private String email;
无法正确接收数据
