網上說mybatis的早前版本配置打印sql還比較簡單,在3.0.6以後配置方式修改了。html
如今的spring-mybatis.xml配置以下:spring
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="configLocation" value="classpath:conf/mybatis-config.xml"></property> <!-- 自動掃描mapping.xml文件 --> <property name="mapperLocations" value="classpath:com/cyber/vip/dao/*.xml"></property> </bean>
mybatis-config.xml:sql
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <settings> <!-- 打印查詢語句 --> <setting name="logImpl" value="STDOUT_LOGGING" /> </settings> <!-- mapper已經在spring-mybatis.xml中的sqlSessionFactory配置,這裏再也不須要配置 --> <!-- <mappers> --> <!-- <mapper resource="com/a/b/c/dao/BusinessInfoDaoMapper.xml" /> --> <!-- </mappers> --> </configuration>
不錯,打印SQL只須要加一個setting就能夠了。mybatis
mybatis的日誌打印方式比較多,SLF4J | LOG4J | LOG4J2 | JDK_LOGGING | COMMONS_LOGGING | STDOUT_LOGGING | NO_LOGGING,能夠根據本身的須要進行配置app
settings的更多參數能夠參考官網文檔:http://www.mybatis.org/mybatis-3/zh/configuration.html#settingsspa
