springboot整合日志框架

我就是我 2023-06-25 06:20 79阅读 0赞

springboot推荐使用SLF4j作为日志门面，Logback作为日志实现

但是由于SSM框架自带日志实现包，我们需要整合日志文件，让项目中的日志系统统一由SLF4j管理

详细日志包可以参考下图

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dqZzEzMTQ1MjE_size_16_color_FFFFFF_t_70][]

我们需要将项目中的

comments-logging

log4j

java util  logging

分别用

jcl-over-slf4j.jar

log4j-over-slf4j.jar

jul-to-slf4j.jar

代替。通过中间包来解决ssm框架中log包的依赖。

首先需要将comments-logging.jar排除

<exclusions>
        <exclusion>
    		<groupId>commons-logging</groupId>
    		<artifactId>commons-logging</artifactId>
    	</exclusion>
    </exclusions>

然後加入我們需要加入和替換的jar

<dependency>
    	<groupId>org.slf4j</groupId>
    	<artifactId>slf4j-api</artifactId>
    	<version>1.7.6</version>
    </dependency>
    剩下的两个包，不导入也行
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.7.25</version>
    </dependency> 
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jul-to-slf4j</artifactId>
        <version>1.7.25</version>
    </dependency>
    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>jcl-over-slf4j</artifactId>
        <version>1.7.25</version>
    </dependency>

加入依賴後，測試

package com.atguigu.test;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    
    public class HelloWorld {
    	public static void main(String[] args) {
    		Logger log = LoggerFactory.getLogger(HelloWorld.class);
    		log.info("nihao-name={},age={}","wujg",123);
    		log.debug("nihao-name={},age={}","wujg",123);
    		log.warn("nihao-name={},age={}","wujg",123);
    		log.error("nihao-name={},age={}","wujg",123);
    	}
    
    }

显示如下，即为成功

日志文件输出成功后，我们来学习一下怎么将日志文件输出到指定的位置

我们现在配置文件中配置上我们要将日志文件生成的位置

logging.path=C:/Users/wjg/Desktop/logs

然后在src/main/resources下即application.properties同级目录下，创建logback-spring.xml

原因：***我们在src/main/resources中创建一个logback-spring.xml，注意：-spring在application之后可以扫描到，如果只写logback.xml那么该xml就会优先于application.properties进行扫描，因此无效***

下面是logback-spring.xml配置

<?xml version="1.0" encoding="UTF-8"?>
    
    
    
    
    <configuration  scan="true" scanPeriod="10 seconds">
        <contextName>logback-spring</contextName>
    
        
        <property name="logging.path" value="${C:/Users/wjg/Desktop/log-ww}" />

        <springProfile name="dev">
            <logger name="com.springcloud.consumer.controller" level="debug"/>
        </springProfile>
    
        <root level="info">
            <appender-ref ref="CONSOLE" />
            <appender-ref ref="DEBUG_FILE" />
            <appender-ref ref="INFO_FILE" />
            <appender-ref ref="WARN_FILE" />
            <appender-ref ref="ERROR_FILE" />
        </root>
    
        
    </configuration>

修改开头日志文件生成的位置，我在这里做了一个引用，最后扫描controller也需要修改。

然后启动项目，查看效果

@GetMapping("/get")
        public List getinfo(){
            Logger log = LoggerFactory.getLogger(conController.class);
            List<Book> allBookInfo = bookClient.getAllBookInfo();
            log.debug("haaaaaaaaaaaaaaaaaaaaaaaaaaaaaa");
            log.error("cuole a");
            System.out.println("www");
            return allBookInfo;
    
        }

在指定位置生成了我们指定的日志等级的文件。
