How can I print SQL query result log with log4j?
提问by firia2000
I'm using Spring 3.1.1, MyBatis 3.1.1, MySQL 5.0.67. My Spring configuration is below:
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"/>
And log4.properties is below:
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
With these configuration, I can see SQL query statement which is executed and parameters to that query but I can't see query result log. My log is like this:
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
Is there any way to print log including query result?
有没有办法打印包括查询结果的日志？

Two ways:
两种方式：
- log4j.logger.java.sql.ResultSet=TRACE
- log4j.logger.java.sql.ResultSet=TRACE
Or use the namespaces to set logging. This is the only logging method in mybatis 3.2
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

What works for me is:
对我有用的是：
log4j.logger.org.springframework.jdbc.core.StatementCreatorUtils=TRACE
log4j.logger.org.springframework.jdbc.core.StatementCreatorUtils=TRACE
This prints entries like these:
这将打印如下条目：
...
TRACE SimpleAsyncTaskExecutor-1 org.springframework.jdbc.core.StatementCreatorUtils - Setting SQL statement parameter value: column index 1, parameter value [12345], value class [java.math.BigDecimal], SQL type 3
TRACE SimpleAsyncTaskExecutor-1 org.springframework.jdbc.core.StatementCreatorUtils - Setting SQL statement parameter value: column index 2, parameter value [ADDRESS], value class [java.lang.String], SQL type 12
TRACE SimpleAsyncTaskExecutor-1 org.springframework.jdbc.core.StatementCreatorUtils - Setting SQL statement parameter value: column index 3, parameter value [20130916], value class [java.math.BigDecimal], SQL type 3
...
In my case I am using running a query inside a JdbcBatchItemWriter in a Spring Batch application, which uses named params so it may not be a general solution.
在我的情况下，我在 Spring Batch 应用程序中的 JdbcBatchItemWriter 中使用运行查询，该应用程序使用命名参数，因此它可能不是通用解决方案。
