使用Built-in formatting来创建log字符串

在一次哦测试中，sonar-qube总是报Use the built-in formatting to contruct this argument,

在网上查了一下，原来它是推荐这样做：

log.info("#{} {} is completed.",index,task);

下面是全部代码，供你参考：

package logbackCfg;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class BuildinTester {
    private final static Logger log = LoggerFactory.getLogger(BuildinTester.class);
    
    public static void main(String[] args) {
        int index=3;
        String task="cleanExpiredData";
        
        // Traditional way to contruct a log msg
        log.info("#"+index+" "+task+" is completed.");
        
        // Built-in formatting to contruct a log msg
        log.info("#{} {} is completed.",index,task);
    }
}
