只重写infor 方法。
增强类JSON
package logger;
import org.slf4j.Logger;
public class JsonLogger extends LoggerDecorator{
public JsonLogger(Logger logger) {
super(logger);
}
public void info(String s) {
String str = "log前缀 json格式化->";
super.info(str+s);
}
}
LoggerJsonFactory 工厂类
package logger;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class LoggerJsonFactory {
public static Logger getLogger(Class<?> clazz){
Logger logger = LoggerFactory.getLogger(clazz);
return new JsonLogger(logger);
}
}
package logger;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class Main {
static Logger log = LoggerFactory.getLogger(Main.class);
static Logger log1 = LoggerJsonFactory.getLogger(Main.class);
public static void main(String[] args) {
log1.info("aaaa");
}
}
打印结果
11:12:29.829 [main] INFO logger.Main - log前缀 json格式化->aaaa
