一、yaml配置

1.application.yaml

person:
  name: lds
  age: 3
  happy: true
  brith: 2020/8/08
  maps: {k1:v1,l2:v2}
  lists:
    code
    music
  dog:
    name: wancai
    age: 3

• •

  可以配置对象，数组等

• •

  注意分号后的空格

• •

  类与属性间存在包含关系

2.怎么用yaml向pojo传递

1. 1.

   创建pojo类 Person and Dog 类

public class Person {
    private String name;
    private Integer age;
    private Boolean happy;
    private Date brith;
    private Map<String,Object> maps;
    private List<Object> lists;
    private Dog dog;
	。。。。。。

2. 注入注解

@Component

@ConfigurationProperties(prefix = "person")

• •

  Component 表示这是个springboot组件

• •

  ConfigurationProperties配置文件

• •

  prefix 指向application.yaml

3. 测试Test

Person{name='lds', age=3, happy=true, brith=Sat Aug 08 00:00:00 GMT+08:00 2020, maps={k1v1=, l2v2=}, lists=[code music], dog=Dog{name='wancai', age=3}}

3.JSR303(数据校验)

@Validated // 数据校验

引入依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-validation</artifactId>
</dependency>

可以验证各种类型

3、application.properties

• •

  配置多环境

• •

  application-test.properties application-dev.properties

• •

  spring,profiles.active=(test)(dev)

• •

  application.yaml

server：
  port: 8080 (默认)
spring:
  profiles:
	active: dev (8081)
---
server:
  port: 8081
	profiles: dev
---
server:
  port: 8082
	profiles: test
