The problem of integrating Alibaba cloud SMS: non static methods cannot be referenced from the static context

When doing Alibaba cloud SMS integration , The signature never passed , Here use the tested API：

The video should be the original SDK, Here I use the new version ：

    /** *  Use AK&SK Initialization account Client * @param accessKeyId * @param accessKeySecret * @return Client * @throws Exception */
    public static com.aliyun.dysmsapi20170525.Client createClient(String accessKeyId, String accessKeySecret) throws Exception {
    
        Config config = new Config()
                //  Your  AccessKey ID
                .setAccessKeyId(accessKeyId)
                //  Your  AccessKey Secret
                .setAccessKeySecret(accessKeySecret);

        config.endpoint = "dysmsapi.aliyuncs.com";
        return new com.aliyun.dysmsapi20170525.Client(config);
    }

    public static void main(String[] args_) throws Exception {
    
        java.util.List<String> args = java.util.Arrays.asList(args_);
        com.aliyun.dysmsapi20170525.Client client = Sample.createClient("accessKeyId", "accessKeySecret");
        SendSmsRequest sendSmsRequest = new SendSmsRequest()
                .setSignName(" Alibaba cloud SMS test ")
                .setTemplateCode("SMS_154950909")
                .setPhoneNumbers("17683839612")
                .setTemplateParam("{\"code\":\"1234\"}");
        RuntimeOptions runtime = new RuntimeOptions();
        try {
    
            //  Please print the copy code yourself  API  The return value of 
            client.sendSmsWithOptions(sendSmsRequest, runtime);
        } catch (TeaException error) {
    
            //  If necessary , Please print  error
            com.aliyun.teautil.Common.assertAsString(error.message);
        } catch (Exception _error) {
    
            TeaException error = new TeaException(_error.getMessage(), _error);
            //  If necessary , Please print  error
            com.aliyun.teautil.Common.assertAsString(error.message);
        }        
    }
}

Here I initialize createClient Draw a tool class ：AliyunUtils：

Don't use static methods here ：

@Component
public class AliyunUtils implements InitializingBean {
    
    @Value("${aliyun.msg.file.keyid}")
    private   String accessKeyId;


    @Value("${aliyun.msg.file.keysecret}")
    private  String accessKeySecret;

    public static String ACCESS_KEY_ID;
    public static String ACCESS_KEY_SECRET;


    @Override
    public void afterPropertiesSet() throws Exception {
    
        ACCESS_KEY_ID=accessKeyId;
        ACCESS_KEY_SECRET=accessKeySecret;
    }

    public  com.aliyun.dysmsapi20170525.Client createClient() throws Exception {
    
        Config config = new Config()
                //  Your  AccessKey ID
                .setAccessKeyId(ACCESS_KEY_ID)
                //  Your  AccessKey Secret
                .setAccessKeySecret(ACCESS_KEY_SECRET);
        //  Domain name visited 
        config.endpoint = "dysmsapi.aliyuncs.com";
        return new com.aliyun.dysmsapi20170525.Client(config);
    }
}

In the implementation class ：AliyunUtils It's through new Object instance called ,

    @Override
    public boolean send(Map<String, Object> param, String phone) throws Exception {
    
        if (StrUtil.isEmpty(phone)){
    
            return false;
        }
        AliyunUtils aliyunUtils=new AliyunUtils();
        //java.util.List<String> args = java.util.Arrays.asList(args_);
        com.aliyun.dysmsapi20170525.Client client = aliyunUtils.createClient();
     
        SendSmsRequest sendSmsRequest = new SendSmsRequest()
                .setSignName(" Alibaba cloud SMS test ")
                .setTemplateCode("SMS_154950909")
                .setPhoneNumbers("176xxxxxxxx")
                .setTemplateParam("{\"code\": "+ param.get("code")+"}");
                /*.setTemplateParam("{\"code\":\"1234\"}");*/
        RuntimeOptions runtime = new RuntimeOptions();
        try {
    
            //  Please print the copy code yourself  API  The return value of 
            client.sendSmsWithOptions(sendSmsRequest, runtime);
        } catch (TeaException error) {
    
            //  If necessary , Please print  error
            com.aliyun.teautil.Common.assertAsString(error.message);
        } catch (Exception _error) {
    
            TeaException error = new TeaException(_error.getMessage(), _error);
            //  If necessary , Please print  error
            com.aliyun.teautil.Common.assertAsString(error.message);
        }

        return true;
    }
}

The following is how static methods are called ： take createClient Defined as a static method , Pay attention to is ：
This method will not get the value , Will report a mistake : Cannot reference a non static method from a static context

@Value("${aliyun.msg.file.keysecret}")
 private  String accessKeySecret;

Ordinary variables are in use @value When the annotation , Add directly to the variable @value annotation , And pass spring The expression is written with the value you want to get , You can inject configuration values into variables . But if it is a static variable, it cannot be injected in this way , So how do static variables pass @value Annotations are injected , This sum spring Injecting static variables is similar , Need to write a set Method ,spring By calling set Method to inject , And assign the injected value to the static variable

@Component
public class AliyunUtils {
    

    @Value("${aliyun.msg.file.keyid}")
    public void setKey(String key) {
    
        AliyunUtils.ACCESS_KEY_ID = key;
    }


    @Value("${aliyun.msg.file.keysecret}")
    public void setSecret(String secret) {
    
        AliyunUtils.ACCESS_KEY_SECRET = secret;
    }

    public static String ACCESS_KEY_ID;
    public static String ACCESS_KEY_SECRET;


    public static com.aliyun.dysmsapi20170525.Client createClient() throws Exception {
    
        Config config = new Config()
                //  Your  AccessKey ID
                .setAccessKeyId(ACCESS_KEY_ID)
                //  Your  AccessKey Secret
                .setAccessKeySecret(ACCESS_KEY_SECRET);
        //  Domain name visited 
        config.endpoint = "dysmsapi.aliyuncs.com";
        return new com.aliyun.dysmsapi20170525.Client(config);
    }
}

Here you call the static method directly

Both methods actually take the configuration file key and secret, And assign it to a static variable
