1.搭建SpringBoot工程

1.1创建一个空的Maven工程

1.2 添加SpringBoot的依赖

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
    
        <groupId>com.ias</groupId>
        <artifactId>logback-springboot-demo</artifactId>
        <version>1.0-SNAPSHOT</version>
    
        <parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.1.3.RELEASE</version>
            <relativePath/> 
        </parent>
    
        <properties>
            <java.version>1.8</java.version>
        </properties>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
        </dependencies>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>
    </project>

1.3 创建Spring配置文件

1.4在application-dev.xml中添加配置

server:
      port: 8764
    spring:
      application:
        name: logback-server
      mvc:
        servlet:
          load-on-startup: 1
    logging:
      level:
        root: INFO
      path: ../logs/oil/
      config: classpath:logback-spring.xml

1.5添加logback.xml配置文件

1.6内容如下，内容也是本文的重点，有对应的注释

    </configuration>

1.7创建启动文件主文件

package com.ias;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class LogApp {
        public static void main(String[] args) {
            SpringApplication.run(LogApp.class,args);
        }
    }

1.8 添加测试文件

package com.ias.contoller;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    @RestController
    public class HelloController {
        private final static Logger logger = LoggerFactory.getLogger(HelloController.class);
        @RequestMapping(value = "/index")
        public String index(){
            logger.debug("debug-test");
            logger.info("info-test");
            logger.error("error-test");
            return "index";
        }
    }

1.9运行启动类，开始测试
