### 一，需求 ###

实现不同级别的日志输出到不同的文件，不同的环境使用不同的日志策略，并且按照大小和时间进行滚动。下面通过一个简单的小例子实现。

### 二，实现 ###

1，pom

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
    
            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
            </dependency>

2，项目结构

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9tcmxlZS5ibG9nLmNzZG4ubmV0_size_16_color_FFFFFF_t_70][]

3，配置文件

#application.yml
    
    logging:
      config: classpath:logback/logback-spring.xml
      #path: D:/logs
    spring:
      profiles:
        active: dev
    
    
    #application-dev.yml
    
    server:
      port: 8081
    
    
    #application-test.yml
    
    server:
      port: 8081
    
    
    #application-prod.yml
    
    server:
      port: 8081

日志配置logback-spring.xml

            </root>
        </springProfile>
    
    </configuration>

### 三，测试 ###

启动项目访问测试

@Slf4j
    @RestController
    public class MyController {
    
        @GetMapping("test")
        public String test1() {
            log.trace("I am trace logging");
            log.debug("I am debug logging");
            log.info("I am info logging");
            log.warn("I am warn logging");
            log.error("I am error logging");
            return "logger finish";
        }
    
    }

完成！！！

### 4，结束语 ###

感兴趣的小伙伴可以在此基础上进行扩展。。。最近较忙由于时间问题不在赘述。
