乐观锁

说明

save时 version 字段会自动填充0，update(实体类)、delete(实体类)自动会增加version条件：where version=?

示例

实体类

@Data
@Table
public class SysUser {

    @TableId
    private Integer id;

    private String userName;

    private String password;
    
    private Integer roleId;

    private LocalDateTime createTime;

    @Version
    private Integer version;
}

Mapper

继承 MybatisMapper 即可

public interface SysUserMapper extends MybatisMapper<SysUser> {

}

如何使用

@Service
public class Test{

    @Autowired
    private SysUserMapper sysUserMapper;

    public void demo() {
        SysUser sysUser=new SysUser();
        sysUserMapper.save(sysUser);
    }
}

前往@Version 查看
