为JpaTransactionManager启用日志记录

在启用JPATransactionManager的日志记录方面，这对我有用：1.下载logback jar（logback-
classic-1.0.1.jar，logback-
core-1.0.1.jar）并放入classpath。由于我使用的是SLF4J，因此我还有log4j-over-
slf4j-1.6.4.jar和slf4j-api-1.6.4.jar。2.使用以下logback.xml（在WEB-INF /
classes中）进行配置：

<?xml version="1.0" encoding="UTF-8"?><configuration><appender name="stdout" >    <enprer>        <pattern> %d %p [%c] - &lt;%m&gt;%n        </pattern>    </enprer>    <filter >        <level>DEBUG</level>    </filter></appender><appender name="FILE" >    <file>${catalina.home}/logs/application.log</file>    <rollingPolicy >        <fileNamePattern>${catalina.home}/logs/application-%d{yyyy-MM-dd}.%i.log</fileNamePattern>        <timebasedFileNamingAndTriggeringPolicy > <maxFileSize>20MB</maxFileSize>        </timebasedFileNamingAndTriggeringPolicy>    </rollingPolicy>    <enprer>        <pattern> %d %p [%c] - &lt;%m&gt;%n        </pattern>    </enprer>    <filter >        <level>ALL</level>    </filter></appender><logger name="org.hibernate.transaction.JDBCTransaction" level="DEBUG"/><logger name="org.hibernate.jdbc.ConnectionManager" level="DEBUG"/><logger name="org.springframework.orm.jpa.JpaTransactionManager" level="DEBUG"/><root level="ERROR">    <appender-ref ref="FILE"/></root></configuration>
