配置文件：

 

 

 

 

 

 

创建映射文件：

package org.example.pojo;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component           //使用Component注解，声明一个组件，被控制器依赖注入
@ConfigurationProperties(prefix = "obj")                //obj为配置文件中key的前缀
public class StudentProperties
{
    private String sname;
    private int sage;

    public String getSname()
    {

        return sname;
    }

    public void setSname(String sname)
    {

        this.sname = sname;
    }

    public int getSage()
    {

        return sage;
    }

    public void setSage(int sage)
    {

        this.sage = sage;
    }

    @Override
    public String toString()
    {

        return "StudentProperties [sname=" + sname + ", sage=" + sage + "]";
    }
}

 

 

 

 

 

 

测试：

package org.example.controller;

import org.example.pojo.StudentProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
public class ConfigurationPropertiesController
{

    @Autowired
    StudentProperties studentProperties;


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

        return studentProperties.toString();
    }

}
