springboot(10)日志记录

## 1、配置 ##

springboot默认使用logback日志框架。  
在src/main/resources路径下创建logback.xml文件，模板见2。springboot则会自动读取该配置文件并启动logback日志框架。

## 2、配置文件 ##

## 3、使用 ##

import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    @Controller
    public class TestAction { 
    
        private final static Logger logger = LoggerFactory.getLogger(TestAction.class);
    
        @RequestMapping("/index")
        public String index() {
    
            logger.info("记录日志");
            return "/index";
        }
    }
