原因:在mybatis中使用二级缓存时候就必须需要将实体类序列化implements Serializable,我的mapper文件使用了<cache/>标签，使用了mybatis提供的二级缓存，所以在我的实体类里面必须序列化

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.baizhi.dao.UserDao">
     <!-- 在这里使用了二级缓存 实体类必须要实现序列化接口 -->
    <cache/>
    <select id="selectAllUsers" resultType="User">
        select id,
               phone,
               password,
                name,
        from c_user
    </select>
</mapper>

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User implements Serializable {
private String id;
private String phone;
private String password;
private String name;
}
