1.引入依赖

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-configuration-processor</artifactId>
<version>1.5.3.RELEASE</version>
</dependency>

2.配置文件（application.yml）

要注意属性名冒号后与值要有一个空格

girl:    age: 100    size: hello3.创建一个属性类(GirlPropertiespackage com.example.Properties;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.stereotype.Component;/** * Created by wangjiwei on 2017/5/3. */@Component@ConfigurationProperties(prefix = "girl")public class GirlProperties {    private Integer age;    public String getSize() {        return size;    }    public void setSize(String size) {        this.size = size;    }    private String size;    public GirlProperties() {        super();    }    public Integer getAge() {        return age;    }    public void setAge(Integer age) {        this.age = age;    }}
)
