mybatis详解-(5)面向接口

前面helloworld中通过selectOne完成了一次查询，但是那种方法需要将所有的参数都写在代码中，包括配置文件的命名空间。这里提供一种通过接口式编程，将所有的方法都定义为接口。在代码中调用接口，实际传递的参数都放置在配置文件中。

1.创建实例对象

Employee

package org.mybatis.settings;

public class Employee {
   
     

    private Integer id;
    private String lastName;
    private String email;
    private String gender;

    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public String getGender() {
        return gender;
    }
    public void setGender(String gender) {
        this.gender = gender;
    }
    @Override
    public String toString() {
        return "Employee [id=" + id + ", lastName=" + lastName + ", email=" + email
                + ", gender=" + gender + "]";
    }
}
