SSM框架引入logback日志框架

1、本章主要结合实例描述如何在SpringMVC框架中引入logback日志框架，关于常见的几种日志框架的介绍和性能对比大家可以自行去了解。

2、整合logback：

2.1、jar包引入，logback-ext-spring为spring支持jar

1. <dependency>
2. groupId>ch.qos.logback</groupId>
3. <artifactId>logback-classic</artifactId>
4. <version>1.1.2</version>
5. </dependency>
7. <dependency>
8. <groupId>ch.qos.logback</groupId>
9. <artifactId>logback-core</artifactId>
10. <version>1.1.2</version>
11. </dependency>
13. <dependency>
14. <groupId>org.logback-extensions</groupId>
15. <artifactId>logback-ext-spring</artifactId>
16. <version>0.1.1</version>
17. </dependency>

2.2、web.xml中配置监听器，param-name的配置参考WebLogBackConfigurer类

1. <context-param>
2. <param-name>logbackConfigLocation</param-name>
3. <param-value>classpath:logback.xml</param-value>
4. </context-param>
6. <listener>
7. <listener-class>ch.qos.logback.ext.spring.web.LogbackConfigListener</listener-class>
8. </listener>

2.3、配置日志相关属性logback.xml，关于详细的配置可以参考一篇博客，里面讲的很详细：llogback.xml

项目在D盘，这里配置的日志输出路径是：D:\local\logs\..，目录在项目启动时会自动创建

1. <?xmlversion="1.0"encoding="UTF-8"?>
2. <configuration>
4. <propertyname="log.root.level"value="DEBUG"/>
5. <propertyname="log.other.level"value="ERROR"/>
6. <propertyname="log.base"value="/local/logs"/>
7. <propertyname="log.moduleName"value="dubbo-provider"/>
8. <propertyname="log.max.size"value="20MB"/>
11. <appendername="stdout"class="ch.qos.logback.core.ConsoleAppender">
12. <encoderclass="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
13. <Pattern></Pattern>
14. </encoder>
15. </appender>
18. <appendername="file"class="ch.qos.logback.core.rolling.RollingFileAppender">
19. <File>${log.base}/${log.moduleName}.log</File>
21. <rollingPolicyclass="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
22. <FileNamePattern>
23. </FileNamePattern>
25. <timeBasedFileNamingAndTriggeringPolicyclass="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
26. <maxFileSize>${log.max.size}</maxFileSize>
27. </timeBasedFileNamingAndTriggeringPolicy>
28. </rollingPolicy>
30. <layoutclass="ch.qos.logback.classic.PatternLayout">
31. <pattern></pattern>
32. </layout>
33. </appender>
36. <loggername="com.dubbo.provider"additivity="false">
37. <levelvalue="debug"/>
38. <appender-refref="stdout"/>
39. <appender-refref="file"/>
40. </logger>
42. <rootlevel="debug">
43. <appender-refref="stdout"/>
44. <appender-refref="file"/>
45. </root>
46. </configuration>

3、启动项目，如果有输出日志则说明配置成功，可以根据项目需求修改logback.xml参数
