Spring Boot 之注解@Component @ConfigurationProperties(prefix = sms)

從spring-boot開始，已經支持yml文件形式的配置，@ConfigurationProperties的大致作用就是通過它可以把properties或者yml配置直接轉成對象

?

例如：

配置文件:
sms.url=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
sms.appkey=XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
sms.secret=XXXXXXXXXXXXXXXXXXXXXXXXXXXXX
sms.signName=XXXXXXXXXXXXXXXXXXXXXXXXXXX
sms.tplCode=XXXXXXXXXXXXXXXXXXXXXXXXXXXX
sms.type=normal

?

JAVA代碼：
@Component
@ConfigurationProperties(prefix = "sms")
public class SmsSettings {private  String url ="";private  String appkey ="";private  String secret ="";private  String signName ="";private  String tplCode ="";private  String type ="";private  String open ="";private  String tplCode2 ="";public String getUrl() {return url;}public void setUrl(String url) {this.url = url;}public String getAppkey() {return appkey;}public void setAppkey(String appkey) {this.appkey = appkey;}public String getSecret() {return secret;}public void setSecret(String secret) {this.secret = secret;}public String getSignName() {return signName;}public void setSignName(String signName) {this.signName = signName;}public String getTplCode() {return tplCode;}public void setTplCode(String tplCode) {this.tplCode = tplCode;}public String getType() {return type;}public void setType(String type) {this.type = type;}public String getOpen() {return open;}public void setOpen(String open) {this.open = open;}public String getTplCode2() {return tplCode2;}public void setTplCode2(String tplCode2) {this.tplCode2 = tplCode2;}}

通過注解@ConfigurationProperties來配置redis

@Configuration    
@EnableAutoConfiguration  
public class RedisConfig {  @Bean    @ConfigurationProperties(prefix="spring.redis.poolConfig")    public JedisPoolConfig getRedisConfig(){    JedisPoolConfig config = new JedisPoolConfig();  return config;    }    @Bean    @ConfigurationProperties(prefix="spring.redis")    public JedisConnectionFactory getConnectionFactory(){    JedisConnectionFactory factory = new JedisConnectionFactory();    factory.setUsePool(true);  JedisPoolConfig config = getRedisConfig();    factory.setPoolConfig(config);    return factory;    }    @Bean    public RedisTemplate<?, ?> getRedisTemplate(){    RedisTemplate<?,?> template = new StringRedisTemplate(getConnectionFactory());    return template;    }    }
