19案例-编写实体类持久层和业务层代码

cn.bjut.domain.User

/**
 * 用户表的实体类
 */
public class User implements Serializable {
    private Integer id;
    private String username;
    private String password;
    private Integer age;
    private String sex;
    private String email;

    //=========get/set方法省略===========//

因为是mysql单表操作CRUD

所以可以选用： 通用mapper + DAO层接口继承 + 实体类注解映射 的方案

    <dependency><!--通用mapper对spring的集成-->
      <groupId>tk.mybatis</groupId>
      <artifactId>mapper-spring</artifactId>
      <version>1.1.5</version>
    </dependency>
    <dependency><!--Mybatis 通用 Mapper Jar 集成-->
      <groupId>tk.mybatis</groupId>
      <artifactId>mapper</artifactId>
      <version>4.1.5</version>
    </dependency>
