1.yml增加配置

注意：冒號後面一定要有一個空格

company:
  name: 天霸
  address: 北京市海淀區

2.編寫測試類

（1）通過value獲取

    @Value("${company.name}")
    private String name;
    @Value("${company.address}")
    private String address;

    @RequestMapping("/testValue")
    public String getCompany(){
        return "name:"+name+";address:"+address;
    }
 

（2）基於properties獲取

      寫CompanyConstantk類

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

@Component
@ConfigurationProperties(prefix = "company")//獲取配置名稱

public class CompanyConstant {

    private String name;

    private String address;

    public void setName(String name){
        this.name=name;
    }

    public String getName(){
        return name;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getAddress() {
        return address;
    }
}
 

獲取屬性值

 @Autowired
    private CompanyConstant companyConstant;
    @RequestMapping("/testProperties")
    public String getCompanyByProperties(){
        return  "通過Properties檔案獲取的》》》》"+"name:"+companyConstant.getName()+";address:"+companyConstant.getAddress();
    }

3.完整程式碼

@RestController
public class TestController {
    private static final Logger logger = LoggerFactory.getLogger(TestController.class);
    
    //獲取屬性值
    @Value("${company.name}")
    private String name;
    @Value("${company.address}")
    private String address;

    @RequestMapping("/testValue")
    public String getCompany(){
        return "通過value獲取的》》》》"+"name:"+name+";address:"+address;
    }

    @Autowired
    private CompanyConstant companyConstant;//注入配置類

    @RequestMapping("/testProperties")
    public String getCompanyByProperties(){
        return  "通過Properties檔案獲取的》》》》"+"name:"+companyConstant.getName()+";address:"+companyConstant.getAddress();
    }
}
