springboot(2)

实现在application.yaml中进行赋值的操作

Person.class

@ConfigurationProperties(prefix = "person")//容器中对person进行绑定这样在yaml中就可以直接赋值了
@Component  //放入容器中
@Data     //自动创建get set方法
@ToString
public class Person {
    private String  userName;
    private Boolean boss;
    private Date birth;
    private Integer age; 
    private Pet pet;
    private String[] interests;
    private List<String> animal;
    private Map<String,Object> score;
    private Set<Double> salarys;
    private Map<String,List<Pet>> allpets;


}

application.yml 赋值的格式

person:
  userName: zhangsan
  boss: true
  birth: 2019/12/9
  age: 18
  #interests: [篮球，足球] 行内写法
  interests:
    - 篮球
    - 足球
    - 18
  animal: [啊毛，阿狗]
  score:
    english: 80
    math: 90
  salarys:
    - 9999
    - 88888
  pet:
    name: zhangs
    weight: 32
  allpets:
    sick:
      - {name: sss,weight: 99}
      - name: 澳毛
        weight: 336
    health:
      - name: jiangkang
        weight: 66

ps:本来很简单，但是却在运行器报错，因为birth是date类型我写成了data提示我转型错误唉， 还有就是 name: 1 一定要有空格。
name="sfs \n 44" 会空行， 单引号会原样输出

HelloController.class

@RestController
public class HelloController {
    @RequestMapping("/hello")
    public String Str(){
        return "sfsf";
    }
    @Autowired   //从容器中拿出Person对象
    Person person;
    @RequestMapping("/7777")
    public Person person(){
        return person;
    }
}

在maven中导入依赖，这样我们在yaml中输入就会有提示

       <dependency>
           <groupId>org.springframework.boot</groupId>
           <artifactId>spring-boot-configuration-processor</artifactId>
           <optional>true</optional>
       </dependency>

为了使maven打包更加便捷，我们可以让这个提示不打包

   <exclude>
                            <groupId>org.springframework.boot</groupId>
                            <artifactId>spring-boot-configuration-processor</artifactId>
                        </exclude>
                    </excludes>

2.2欢迎页支持

• 静态资源路径下 index.html

• controller能处理/index
