spring boot 读取application.yml自定义配置文件

（1）引入依赖包

<!--读取资源文件依赖-->
<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
            <optional>true</optional>
        </dependency>

(2)application.yml自定义配置

employee :
   salary: 2000
   title: programer

（3）创建自定义字段bean

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@ConfigurationProperties(prefix = "employee")
public class EmployeeApplicationUnt {

    private String salary;
    private String title;


    public String getSalary() {
        return salary;
    }

    public void setSalary(String salary) {
        this.salary = salary;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }
}

(4)测试获取资源文件中的值

 @Autowired
    private  EmployeeApplicationUnt salar;

 @RequestMapping("/getEmp")
    public String getEmp(){

        return salar.getSalary();
    }

浏览器打开已经获取到值了
