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

Posted 2020-09-19 Mr_伍先生

从spring-boot开始，已经支持yml文件形式的配置，@ConfigurationProperties的大致作用就是通过它可以把properties或者yml配置直接转成对象

 

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代码：
@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;
    }
    
}

 

 

 

通过注解@ConfigurationProperties来配置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;    
    }    
      
}
