Spring boot 读取配置文件application.yml （自定义属性值）

引入pom.xml支持
这个是对@ConfigurationProperties注解支持的包

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

yml配置

wechat:
      token: "bbb"

创建Bean

@Component
//接收application.yml中的wechat下面的属性
@ConfigurationProperties(prefix = "wechat")
public class ReadApplicationUntil {
    private String token;

    public String getToken() {
        return token;
    }

    public void setToken(String token) {
        this.token = token;
    }
}

单元测试

 	@Autowired
    private ReadApplicationUntil readApplicationUntil;
    
    @Test
    public void yml() {
        System.out.println(readApplicationUntil.getToken());
    }
