技術標籤：SpringBootloglog4j2整合log4j專案使用log4jlog4j log4j2專案整合log4j2

pom.xml新增依賴：

		<!-- springboot預設是用logback的日誌框架的，所以需要排除logback，不然會出現jar依賴衝突的報錯 -->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter</artifactId>
			<exclusions>
				<exclusion> <!-- exclude掉spring-boot的預設log配置 -->
					<groupId>org.springframework.boot</groupId>
					<artifactId>spring-boot-starter-logging</artifactId>
				</exclusion>
			</exclusions>
		</dependency>
		<!-- log4j日誌 -->
		<dependency>

		<!-- 有其他jar依賴log4j -->
		<dependency>

		</dependency>
		<dependency>
			<groupId>com.lmax</groupId>
			<artifactId>disruptor</artifactId>
			<version>3.3.6</version>
		</dependency>
 

application.properties新增配置：

#Log4j2
logging.config=classpath:log4j2.xml

src/main/resources新增XML檔案：log4j2.xml

注意：

需要將xml中 "XXX" 進行更改，如："logs/XXX-info.log" 建議改為 "logs/當前專案名-info.log"（共計12處）

需要將 "com.test.dao" 更改為自己的專案中的dao介面所在包名（共計1處）
