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

<?xml version="1.0" encoding="UTF-8"?>

    <shutdownHook class="ch.qos.logback.core.hook.DelayingShutdownHook"/>

    <!-- Logger 根目录 -->
    <root level="INFO">

        <appender-ref ref="DEBUG-OUT" />
        <appender-ref ref="TRACE-OUT" />
    </root>
</configuration>

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";
    }
}
