logback同时输出到控制台和文件,并按级别输出到不同的文件--配置开箱即用
第一步:添加maven依赖,编写pom.xml文件
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.2.3</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>1.2.3</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.21</version>
</dependency>
第二步:创建logback-test.xml文件,创建位置如下
logback-test.xml文件内容如下
<?xml version="1.0" encoding="UTF-8" ?>
<configuration>
<!-- 输出到控制台 -->
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<!-- 输出的格式 -->
<encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<!--输出错误日志-->
<appender name="ERROR" class="ch.qos.logback.core.rolling.RollingFileAppender">
<!-- 日志名称的格式 -->
<encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
<file>logs/error.log</file>
<!-- 配置滚动的策略 -->
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>logs/%d{yyyy-MM-dd}/error.log</fileNamePattern>
<!-- 保存的最长时间:天数 -->
<maxHistory>10</maxHistory>
</rollingPolicy>
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>ERROR</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
</appender>
<appender name="INFO" class="ch.qos.logback.core.rolling.RollingFileAppender">
<encoder>
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
<file>logs/info.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>logs/%d{yyyy-MM-dd}/XXXXMo.log</fileNamePattern>
<maxHistory>10</maxHistory>
</rollingPolicy>
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<!--可以修改成INFO,DEBUG等-->
<level>DEBUG</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
</appender>
<root level="debug">
<appender-ref ref="STDOUT" />
<appender-ref ref="ERROR" />
<appender-ref ref="INFO"/>
</root>
</configuration>
第三步(仅为测试):
@SpringBootApplication
@Component
@RestController
public class DemoApplication {
private static final Logger logger = LoggerFactory.getLogger(DemoApplication.class);
@Autowired
private Test test;
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
@RequestMapping("/get")
public void get() {
logger.error(DemoApplication.class+"error");
logger.info(DemoApplication.class+"success");
}
}
检查效果(控制台输出:)
日志文件输出:
好的,logback配置,同时输出控制台和日志文件,日志文件按不同级别输出到不同日志文件到此结束。
