2小时学会Spring Boot学习-项目属性配置

1.项目属性配置

resources文件夹下新建 application.yml application-dev.yml application-prod.yml文件

application.yml按需读取dev或prod中的参数

application.yml文件

spring:
  profiles:
    active: dev

application-dev.yml文件

server:
  port: 8080
girl:
  cupSize: B
  age: 18

application-prod.yml文件

server:
  port: 8081
girl:
  cupSize: F
  age: 18

新建GirlProperties.java

@Component
@ConfigurationProperties(prefix = "girl")
public class GirlProperties {

    private  String cupSize;

    private  Integer age;


    public String getCupSize() {
        return cupSize;
    }

    public void setCupSize(String cupSize) {
        this.cupSize = cupSize;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

}

controller类中调用

@RestController
public class HelloController {

   @Autowired
   private GirlProperties girlProperties;

    @GetMapping(value = "/hello")
    public String say(){
        return girlProperties.getCupSize();
    }
}
