### 查看依赖冲突 ###

#### 安装idea插件并重启idea ####

#### 当 `pom.xml` 下方未出现切换选项时 ####

#### 查看冲突依赖 ####

![在这里插入图片描述][b907be453c47493d8732f9427b43b544.png_pic_center]

#### 修改冲突依赖版本 ####

<dependency>
        <groupId>org.mybatis</groupId>
        <artifactId>mybatis</artifactId>
        
        <version>3.5.9</version>
    </dependency>

### 全局日志管理 ###

#### 引入日志相关依赖 ####

<dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>1.7.36</version>
    </dependency>
    <dependency>
        <groupId>ch.qos.logback</groupId>
        <artifactId>logback-classic</artifactId>
        <version>1.2.11</version>
    </dependency>

#### 添加全局日志配置 ####

logging:
      config: demo/src/main/resources/logback.xml
      level:
        com.example.demo: trace

#### 在 `resources` 目录下创建 `logback.xml` 配置文件 ####

<?xml version="1.0" encoding="UTF-8"?>
    <configuration debug="false">
        
        <property name="LOG_HOME" value="/Users/lee/Documents/AAA-PLee/C-Code/java-app/log"/>

            </encoder>
            
            <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
                <MaxFileSize>10MB</MaxFileSize>
            </triggeringPolicy>
        </appender>
    
        
        <logger name="org.springframework" level="INFO"/>
        <logger name="com.hl.magic" level="INFO"/>
        <root level="INFO">
            <appender-ref ref="CONSOLE"/>
            <appender-ref ref="FILE"/>
        </root>
    </configuration>
