mybatis3.2.7有一個(gè)bug,使用log4j2 (2.0.2)版本時(shí),會(huì)找不到類 ,導(dǎo)致啟動(dòng)失敗,詳見 https://github.com/mybatis/mybatis-3/issues/235 但沒過多久 , 3.2.8就已經(jīng)修復(fù)了這個(gè)bug , 最新的mybatis3.2.8下載地址為: https://github.com/mybatis/mybatis-3/releases mybatis 3.2.8 整合 log4j2.0.2并不復(fù)雜 , 如果用spring-mvc做為web框架 , 以下是使用步驟:
1. pom.xml添加依賴項(xiàng)   1 <dependency> 2 <groupId>org.slf4j</groupId> 3 <artifactId>slf4j-api</artifactId> 4 <version>1.7.7</version> 5 </dependency> 6 <dependency> 7 <groupId>org.apache.logging.log4j</groupId> 8 <artifactId>log4j-api</artifactId> 9 <version>${log4j2.version}</version> 10 </dependency> 11 <dependency> 12 <groupId>org.apache.logging.log4j</groupId> 13 <artifactId>log4j-core</artifactId> 14 <version>${log4j2.version}</version> 15 </dependency> 16 <dependency> 17 <groupId>org.apache.logging.log4j</groupId> 18 <artifactId>log4j-web</artifactId> 19 <version>${log4j2.version}</version> 20 </dependency> 21 <dependency> 22 <groupId>org.apache.logging.log4j</groupId> 23 <artifactId>log4j-slf4j-impl</artifactId> 24 <version>2.0.2</version> 25 </dependency> slf4j的二項(xiàng)好象不加也行 , 大家可以自行試試
2. web.xml中增加listener 1 <listener> 2 <listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class> 3 </listener> 4 <filter> 5 <filter-name>log4jServletFilter</filter-name> 6 <filter-class>org.apache.logging.log4j.web.Log4jServletFilter</filter-class> 7 </filter> 8 <filter-mapping> 9 <filter-name>log4jServletFilter</filter-name> 10 <url-pattern>/*</url-pattern> 11 <dispatcher>REQUEST</dispatcher> 12 <dispatcher>FORWARD</dispatcher> 13 <dispatcher>INCLUDE</dispatcher> 14 <dispatcher>ERROR</dispatcher> 15 </filter-mapping> 上面這一段,加在web.xml最開頭
3. maven項(xiàng)目的resouces目錄下 , 放置log4j2.xml 1 <?xml version="1.0" encoding="UTF-8"?> 2 <Configuration status="off" monitorInterval="1800"> 3 4 <Appenders> 5 <Console name="Console" target="SYSTEM_OUT"> 6 <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" /> 7 </Console> 8 </Appenders> 9 10 <Loggers> 11 <Root level="debug"> 12 <AppenderRef ref="Console" /> 13 </Root> 14 </Loggers> 15 </Configuration> 只要把root logger的級(jí)別調(diào)成debug級(jí)別即可
4.如果采用mybatis-spring項(xiàng)目來集成mybatis, spring配置文件參考下面這樣:  1 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 2 <property name="dataSource" ref="dataSource" /> 3 <property name="configLocation" value="classpath:mybatis-config.xml"></property> 4 <property name="typeAliasesPackage" value="com.cnblogs.yjmyzz.entity"></property> 5 <property name="mapperLocations" value="classpath:mybatis/**/*.xml"></property> 6 </bean> <property name="configLocation" value="classpath:mybatis-config.xml"></property> 這一行,指定了mybatis的主配置文件
5.mybatis-config配置文件 1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration PUBLIC "-////DTD Config 3.0//EN" 3 "http:///dtd/mybatis-3-config.dtd"> 4 <configuration> 5 <settings> 6 <setting name="logImpl" value="LOG4J2" /> 7 </settings> 8 </configuration> 指定mybatis使用log4j2來記錄日志
如果在jboss eap 6.x上部署 , 啟動(dòng)時(shí)會(huì)有一個(gè)error , 但并不影響項(xiàng)目正常運(yùn)行 , 這是log4j2的一個(gè)bug , 估計(jì)在后續(xù)版本中會(huì)修復(fù),詳情見:http://mail-archives./mod_mbox/logging-log4j-dev/201403.mbox/%3CJIRA.12696787.1393155172406.128647.1393632623629@arcas%3E
鑒于國內(nèi)不太方便下載github上的東西,最后給出mybatis-2.3.8.jar包文件下載:mybatis-3.2.8.jar.zip |
