## 工程准备：创建maven工程 ##

### 1.选择maven直接next ###

### 2.输入组织、工程名和版本号点击next,然后在下一个界面直接finish ###

### 3.配置maven本地地址 ###

### 4.引入依赖创建springBoot的启动，Application类 ###

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.1.3.RELEASE</version>
        </parent>
    
        
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            <dependency>
                <groupId> org.springframework.boot </groupId>
                <artifactId> spring-boot-configuration-processor </artifactId>
                <optional> true </optional>
            </dependency>
    
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
            </dependency>
    
            
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-devtools</artifactId>
            </dependency>
    
    
            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
            </dependency>
        </dependencies>

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

### 5.配置springMvc，创建yml文件，名称为application.yml ###

5.1配置端口号及服务器启动后的springMVC加载顺序

server:
      port: 80
    spring:
      mvc:
        servlet:
          load-on-startup: 1

### 6.日志级别输出的配置 ###

配置日志的输出地址和日志的输入级别

logging:
      path: E:\test.log
      level:
        com.fuke: debug

#### 在代码中使用log输出的方式 ####

1.直接获取一个log实例

Logger logger = LoggerFactory.getLogger(MyController.class);
            logger.debug("111");

2.再类上添加注解@Slf4j当前类就可以使用

log.debug("22");
