本文介绍了如何在Spring项目中使用logback进行日志输出。首先，需要在pom.xml中排除slf4j-log4j12的依赖，并添加logback的相关jar包。

Spring 利用logback输出打印日志：

一、pom.xml中添加相应的jar包：

1、首先由于logback的jar包与slf4j-log4j12冲突，所以先去掉相关的jar包：

<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-client</artifactId>
<version>2.3.0</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-auth</artifactId>
<version>2.3.0</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>org.apache.hadoop</groupId>
<artifactId>hadoop-common</artifactId>
<version>2.3.0</version>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
</exclusions>
</dependency>

2、添加logback的相应jar包：

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.6.0</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>log4j-over-slf4j</artifactId>
<version>1.6.0</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>0.9.29</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>0.9.29</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-access</artifactId>
<version>0.9.29</version>
</dependency>
<dependency>
<groupId>org.logback-extensions</groupId>
<artifactId>logback-ext-spring</artifactId>
<version>0.1.2</version>
</dependency>

二、在web.xml中配置监听
<context-param>
<param-name>logbackConfigLocation</param-name>
<param-value>/WEB-INF/config/logback.xml</param-value>
</context-param>
<listener>
<listener-class>
ch.qos.logback.ext.spring.web.LogbackConfigListener
</listener-class>
</listener>

三、将logback的配置文件logback.xml放在/WEB-INF/config/文件夹下：
<?xml version="1.0" encoding="UTF-8"?>
<configuration>

<property name="LOG_HOME" value="/opt/search/nimitzlogs" />

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

<Encoding>UTF-8</Encoding>
<layout class="ch.qos.logback.classic.PatternLayout">

<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
</pattern>
</layout>
</appender>

<appender name="FILEINFO" class="ch.qos.logback.core.rolling.RollingFileAppender">

<Encoding>UTF-8</Encoding>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

<FileNamePattern>${LOG_HOME}/log-user.%d{yyyy-MM-dd}.log</FileNamePattern>

<MaxHistory>30</MaxHistory>
</rollingPolicy>
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} [%file:%line] - %msg%n
</pattern>
</layout>



<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>INFO</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
</appender>

<appender name="FILEERROR" class="ch.qos.logback.core.rolling.RollingFileAppender">

<Encoding>UTF-8</Encoding>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

<FileNamePattern>${LOG_HOME}/log-error.%d{yyyy-MM-dd}.log</FileNamePattern>

<MaxHistory>30</MaxHistory>
</rollingPolicy>
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} [%file:%line] - %msg%n
</pattern>
</layout>



<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>ERROR</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
</appender>

<root level="INFO">
<appender-ref ref="STDOUT"/>
<appender-ref ref="FILEINFO"/>
<appender-ref ref="FILEERROR"/>
</root>

<logger name="org.springframework" level="ERROR">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILEINFO" />
<appender-ref ref="FILEERROR" />
</logger>
<logger name="org.apache.solr" level="ERROR">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILEINFO" />
<appender-ref ref="FILEERROR" />
</logger>
<logger name="net.paoding" level="ERROR">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILEINFO" />
<appender-ref ref="FILEERROR" />
</logger>
<logger name="org.apache.commons" level="ERROR">
<appender-ref ref="STDOUT" />
<appender-ref ref="FILEINFO" />
<appender-ref ref="FILEERROR" />
</logger>

</configuration>

四、测试：
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Test {
private Logger log = LoggerFactory.getLogger(UsrController.class);
public String login(HttpServletRequest request) {
String username = request.getParameter("username");
String password = request.getParameter("password");
log.info("username:{} and pwd:{}", username, password);
return null;
}
}
