MyBatis-Plus 自动填充功能不生效，MyObjectHandler 两个方法不执行

当前使用版本(必填,否则不予处理)

版本 3.0.7.1

该问题是如何引起的？(确定最新版也有问题再提!!!)

重现步骤(如果有就写完整)

实体类：@Data @NoArgsConstructor @AllArgsConstructor @TableName("user") public class User { private Long id; private String name; private Integer age; @TableField(fill = FieldFill.INSERT_UPDATE) private String email; //在创建的时候填充这个字段 private LocalDateTime createDate; //在更新的时候更新这个字段 private LocalDateTime updateDate; //逻辑删除标志 @TableLogic //查询的时候排除这个属性 @TableField(select = false) private Integer delFlag;

}

自定义处理器

@Component public class MyObjectHandler implements MetaObjectHandler {

@Override
public void insertFill(MetaObject metaObject) {
    this.strictInsertFill(metaObject, "email", String.class, "liukun");
    System.out.println("aaa");
    System.out.println("bbb");
}

@Override
public void updateFill(MetaObject metaObject) {
    System.out.println("更新");

}

}

test测试如下 @Test public void test7(){ User user = new User(); user.setName("陈二牛");
```
int insert = userMapper.insert(user);
System.out.println(insert);
```
}

4，控制台打印 ==> Preparing: INSERT INTO user ( id, name, age, email ) VALUES ( ?, ?, ? ) ==> Parameters: 1257479187862765570(Long), 陈二牛, null <== Updates: 1

最后发现 MyObjectHandler 两个方法都不执行
