server:
port: 8881
spring:
application:
name: mySpringBoot
eureka:
client:
enabled: true
service-url:
defaultZone: http://localhost:8761/eureka/
instance:
id: 2
七、附录一 swagger注解
@Api: 修饰整个类,用于controller类上
@ApiOperation: 描述一个接口,用户controller方法上
@ApiParam: 单个参数描述
@ApiModel: 用来对象接收参数,即返回对象
@ApiModelProperty: 对象接收参数时,描述对象的字段
@ApiResponse: Http响应其中的描述,在ApiResonse中
@ApiResponses: Http响应所有的描述,用在
@ApiIgnore: 忽略这个API
@ApiError: 发生错误的返回信息
@ApiImplicitParam: 一个请求参数
@ApiImplicitParam: 多个请求参数
八、附录二 PO,VO,DAO,BO,POJO之间的区别
VO
value object:值对象
通常用于业务层之间的数据传递,由new创建,由GC回收。
PO
persistant object:持久层对象
对应数据库中表的字段。
VO和PO,都是属性加上属性的get和set方法;表面看没什么不同,但代表的含义是完全不同的。
DTO
data transfer object:数据传输对象。
表里面有十几个字段:id,name,gender(M/F),age,conmpanyId(如001)...
页面需要展示四个字段:name,gender(男/女),age,conmpanyName(如今日头条股份有限公司)。
DTO由此产生,一是能提高数据传输的速度(减少了传输字段),二能隐藏后端表结构。
BO
business object:业务对象
BO把业务逻辑封装为一个对象。
PO的组合
POJO
plain ordinary java object:简单无规则java对象
纯的传统意义的java对象,最基本的Java Bean只有属性加上属性的get和set方法。
可以转化为PO、DTO、VO;比如POJO在传输过程中就是DTO。
DAO
data access object:数据访问对象
主要用来封装对数据的访问,注意,是对数据的访问,不是对数据库的访问。
九、喜闻乐见环节
-
要求连接数MySQL据库,通过Mybatis 查询UserInfo对象
-
DDL、DML语句存储在mySpringBoot.sql文件中
