sql - 如何使用 log4j 打印 SQL 查询结果日志？

Question

我使用的是 Spring 3.1.1、MyBatis 3.1.1、MySQL 5.0.67。我的 Spring 配置如下:

<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" destroy-method="close">    
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url" value="${jdbc.url}" />
    <property name="username" value="${jdbc.username}" />
    <property name="password" value="${jdbc.password}" />
    <property name="validationQuery" value="select 1"/>
    <property name="testWhileIdle" value="true"/>
    <property name="timeBetweenEvictionRunsMillis" value="14400000"/>               
    <property name="testOnBorrow" value="false"/>       
</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation" value="classpath:mybatis/myBatisConfig.xml"/>
</bean>

<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
    <constructor-arg ref="sqlSessionFactory"/>
</bean>

<bean id="transactionManager"
    class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
    p:dataSource-ref="dataSource"/>

<tx:annotation-driven transaction-manager="transactionManager"/>

log4.properties 如下:

log4j.logger.org.springframework=DEBUG
log4j.logger.org.apache=DEBUG
log4j.logger.org.mybatis=DEBUG

log4j.logger.java.sql=DEBUG
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
log4j.logger.java.sql.ResultSet=DEBUG

通过这些配置，我可以看到执行的 SQL 查询语句和该查询的参数，但我看不到查询结果日志。我的日志是这样的:

[org.mybatis.spring.SqlSessionUtils] - Creating a new SqlSession
[org.mybatis.spring.SqlSessionUtils] - SqlSession             [org.apache.ibatis.session.defaults.DefaultSqlSession@4ccdd1f] was not registered for synchronization because synchronization is not active
[org.springframework.jdbc.datasource.DataSourceUtils] - Fetching JDBC Connection from DataSource
[org.mybatis.spring.transaction.SpringManagedTransaction] - JDBC Connection     [ProxyConnection[PooledConnection[com.mysql.jdbc.JDBC4Connection@3cfde82]]] will not be managed by Spring
[java.sql.Connection] - ooo Using Connection     [ProxyConnection[PooledConnection[com.mysql.jdbc.JDBC4Connection@3cfde82]]]
[java.sql.Connection] - ==>  Preparing: SELECT col FROM table WHERE col1=? AND col2=? 
[java.sql.PreparedStatement] - ==> Parameters: 93(Integer), 4(Integer)
[org.mybatis.spring.SqlSessionUtils] - Closing non transactional SqlSession     [org.apache.ibatis.session.defaults.DefaultSqlSession@4ccdd1f]
[org.springframework.jdbc.datasource.DataSourceUtils] - Returning JDBC Connection to DataSource

有没有办法打印包括查询结果的日志？

Answer 1

两种方式:

log4j.logger.java.sql.ResultSet=TRACE

或者使用命名空间来设置日志记录。这是mybatis 3.2中唯一的日志方式
