继续在application.properties中添加
wisely2.name=wyf2 wisely2.gender=male2 定义配置类 @ConfigurationProperties(prefix = "wisely2") public class Wisely2Settings { private String name; private String gender; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getGender() { return gender; } public void setGender(String gender) { this.gender = gender; } }若新用新的配置文件 1.5之前
建一个wisely.properties wisely.name=wangyunfei wisely.gender=male
@ConfigurationProperties(prefix = "wisely",locations = "classpath:config/wisely.properties") public class WiselySettings { private String name; private String gender; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getGender() { return gender; } public void setGender(String gender) { this.gender = gender; } } 最后注意在spring Boot入口类加上@EnableConfigurationProperties @SpringBootApplication @EnableConfigurationProperties({WiselySettings.class,Wisely2Settings.class}) public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); } }1.5版本之后 在spring boot（版本1.5.1.RELEASE）项目中，当准备映射自定义的配置文件属性到类中的时候，发现原本的@ConfigurationProperties注解已将location属性移除，因此导致无法正常给配置类的属性赋值(spring boot这么做其实也有他的道理，具体可参考https://github.com/spring-projects/spring-boot/issues/6726)
在@EnableConfigurationProperties取消激活自定义的配置类（重要） 在配置类中采用@Component的方式注册为组件，然后使用@PropertySource来指定自定义的资源目录 代码
