springboot read custom profiles and garbage problem

First, customize a configuration file in the resources directory

As sms.properties

# SMS platform related 
mall.sms.regionId = CH- o hangzhou 
mall.sms.accessKeyId = ********* 
mall.sms.accessKeySecret = ********** 
mall.sms.product = Dysmsapi 
mall.sms.domain = dysmsapi.aliyuncs.com 
mall.sms.timeout = 1000 
mall.sms.signName = Jingan international nations Hui Park 
mall.sms.templateCode = SMS_150172034 
mall.sms.templateParam = {\ "code \": \ "@ code @ \"} 
mall.sms.verify.timeout = 600

Annotate @PropertySource need in this class configured

@Service
@Slf4j
@PropertySource(value="classpath:sms.properties",encoding = "utf-8")
public class SmsService {

    @Autowired
    private RedisManager redisManager;

    @Value("${mall.sms.signName}")
    private String signName;
    @Value("${mall.sms.templateCode}")
    private String templateCode;
    @Value("${mall.sms.templateParam}")
    private String templateParam;
    @Value("${mall.sms.verify.timeout}")
    private long timeout;
}

@PropertySource annotation value of the value of classpath: profile name

Finally, there are two points to note:

First: the need to pay attention to the file format properties should be set to utf-8 
@PropertySource not only need to add value attributes and then reads the configuration file, you need to set encoding to utf-8
