Spring 使用 logback 记录日志

2. logback.xml

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

<configuration>
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">

3. Application.java

package liujiajia.me;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
* Created by liujiajia on 2017/3/23.
*/
@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

4. TestController.java

package liujiajia.me.Controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

/**
* Created by liujiajia on 2017/3/23.
*/
@RestController
@RequestMapping("/Test")
public class TestController {
    private static final Logger logger = LoggerFactory.getLogger("liujiajia.me.Controller.TestController");

    @RequestMapping(value = "/Log", method = RequestMethod.GET)
    public String Log() {
        logger.error("test log");
        return "test log";
    }
}
