使用MyBatis查询user表中所有的女性用户并输出

sex:0代表女性，1代表男性

User

package entity;

import java.sql.Date;

public class User {
    private String username;
    private String password;
    private Integer age;
    private int sex;
    private Date birthdate;
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
    public int getSex() {
        return sex;
    }
    public void setSex(int sex) {
        this.sex = sex;
    }
    public Date getBirthdate() {
        return birthdate;
    }
    public void setBirthdate(Date birthdate) {
        this.birthdate = birthdate;
    }
    @Override
    public String toString() {
        return "User [username=" + username + ", password=" + password + ", age=" + age + ", sex=" + sex
                + ", birthdate=" + birthdate + "]";
    }
