Question

Mybatis怎么能看是否执行了sql语句

Answer 1

配置如下

在pom中增加如下依赖：

<dependency>

<groupId>org.bgee.log4jdbc-log4j2</groupId>

<artifactId>log4jdbc-log4j2-jdbc4.1</artifactId>

<version>1.16</version>

</dependency>

<dependency>

<groupId>org.slf4j</groupId>

<artifactId>slf4j-api</artifactId>

<version>1.7.13</version>

</dependency>

<dependency>

<groupId>org.slf4j</groupId>

<artifactId>slf4j-log4j12</artifactId>

<version>1.7.13</version>

</dependency>

<dependency>

<groupId>org.apache.logging.log4j</groupId>

<artifactId>log4j-api</artifactId>

<version>2.0-beta9</version>

</dependency>

log4j.properties 如下配置 log4j.rootLogger=debug,stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

#log4j.appender.stdout.Target=System.err

log4j.appender.stdout.layout=org.apache.log4j.SimpleLayout

增加一个 log4jdbc.log4j2.prpperties 内容如下：

dbc.spylogdelegator.name=net.sf.log4jdbc.log.slf4j.Slf4jSpyLogDelegator

log4jdbc.debug.stack.prefix=

log4jdbc.sqltiming.warn.threshold=

log4jdbc.sqltiming.error.threshold=

log4jdbc.dump.booleanastruefalse=

log4jdbc.dump.sql.maxlinelength=

log4jdbc.dump.fulldebugstacktrace=

log4jdbc.statement.warn=

log4jdbc.dump.sql.select=

log4jdbc.dump.sql.insert=

log4jdbc.dump.sql.update=

log4jdbc.dump.sql.delete=

log4jdbc.dump.sql.create=

log4jdbc.dump.sql.addsemicolon=

log4jdbc.auto.load.popular.drivers=

log4jdbc.trim.sql=

log4jdbc.trim.sql.extrablanklines=

log4jdbc.suppress.generated.keys.exception=

log4jdbc.drivers=

最后在mybatis的全局配置文件中

<dataSource type="POOLED">

<property name="driver" value="net.sf.log4jdbc.sql.jdbcapi.DriverSpy" />

<property name="url" value="jdbc:log4jdbc:mysql://localhost:3306/test" />

<property name="username" value="root" />

<property name="password" value="" />

</dataSource>

Answer 2

log4j.layout.log4j.stdout=org，比如配置我们最常用的 log4j.File=D.log4j.common.appender.ibatis.logger.logger.ConsoleAppender
