原文教程链接在此http://blog.csdn.net/lxhjh/article/details/51752419。
使用了org.slf4j.Logger和org.slf4j.LoggerFactory
贴三句代码：
protected static Logger logger=LoggerFactory.getLogger(HelloController.class);
logger.debug("访问hello");
logger.debug("访问helloName,Name={}",name);
-----------------------------------------------------------------------------------
记录问题：
按教程正常操作后，日志文件一直没有找到。
解决过程：
1.阅读console输出。
1)发现Spring这里先加载了resource目录下的logback.xml配置文件，然后才是后续的SpringBoot一系列启动执行过程，这里可能涉及Spring的加载机制，暂且放下，留作以后发现。
2)发现这里输出的文字都是乱码，后来在logback.xml中修改了对应的<charset>为utf-8，重启后输出正常。这里猜测eclipse控制台默认解码为utf-8，暂且不做研究。这里同样发现了昨天的问题，就是SpringBoot启动后，代码的修改都不会生效，很是奇怪。
3)还有一个发现，console的输出格式，刚好是 %d %p (%file:%line\)- %m%n 。
2.阅读logback.xml。
配置了两种appender，分别对应<root><logger>，level分别为info、debug。其中配置对应关系，尚需详查。
3.刷新项目目录。
解决。。。。。。坑啊有点，而且打开日志文件，再次从前端访问，日志文件内容并无变化，重启eclipse后打开日志文件，发现有了。。。
这里的刷新机制真心有点奇怪。。。
------------------------------------------
粗略记录三个问题，以待查询：
1.SpringBoot的加载机制，如加入resource下的文件后。
2.SpringBoot刷新机制，如启动后修改代码不生效。
3.日志框架，如log4j,slf4j。
