@ConfigurationProperties使用
application-dev.yml

my:  servers:    port: 8080    threadPool:      maxThreads: 100      minThreads: 8      idleTimeout: 6000

@ConfigurationProperties 使用

** * Created by jiyang on 16:10 2017/12/15 */@Controller@RequestMapping("/tester")@Api(value = "测试页面", description = "测试页面相关接口")@ConfigurationProperties(prefix = "my.servers")public class TestController {    @Getter    @Setter    private int port;    @Getter    @Setter    private Map<String,Object> threadPool;}

2.@EnableConfigurationProperties

//file MyWebServerConfigurationProperties.javaimport org.springframework.boot.context.properties.ConfigurationProperties;@ConfigurationProperties(prefix = "my.webserver")public class MyWebServerConfigurationProperties {    private int port;    private ThreadPool threadPool;    public int getPort() {        return port;    }    public void setPort(int port) {        this.port = port;    }    public ThreadPool getThreadPool() {        return threadPool;    }    public void setThreadPool(ThreadPool threadPool) {        this.threadPool = threadPool;    }    public static class ThreadPool {        private int maxThreads;        private int minThreads;        private int idleTimeout;        public int getIdleTimeout() {            return idleTimeout;        }        public void setIdleTimeout(int idleTimeout) {            this.idleTimeout = idleTimeout;        }        public int getMaxThreads() {            return maxThreads;        }        public void setMaxThreads(int maxThreads) {            this.maxThreads = maxThreads;        }        public int getMinThreads() {            return minThreads;        }        public void setMinThreads(int minThreads) {            this.minThreads = minThreads;        }    }}

// file: MyWebServerConfiguration.javaimport org.springframework.context.annotation.Configuration;import org.springframework.boot.context.properties.EnableConfigurationProperties;@Configuration@EnableConfigurationProperties(MyWebServerConfigurationProperties.class)public class MyWebServerConfiguration {    @Autowired    private MyWebServerConfigurationProperties properties;    /**     *下面就可以引用MyWebServerConfigurationProperties类       里的配置了    */   public void setMyconfig() {       String port = properties.getPort();       // ...........   }
