在Spring中如何使用@Configuration属性前缀和虚线属性来映射属性文件？

@ConfigurationProperties(prefix = "prefix")
public class MyProperties {
    private String property1;
    private String property2;

    // 省略getter和setter方法
}

@Configuration
@EnableConfigurationProperties(MyProperties.class)
public class AppConfig {
    // 省略其他配置
}

prefix.property1=value1
prefix.property2=value2

<bean id="myBean" class="com.example.MyBean">
    <property name="property1" value="${prefix.property1}" />
    <property name="property2" value="${prefix.property2}" />
</bean>
