1. application.conf

确保:

db.default.logStatements=true

此配置实际上是play2中使用的连接池bonecp的设置

This config is actually a setting of bonecp which is connection pool used in play2

将自定义记录器配置添加到conf/logger.xml.

Add a custom logger configuration to conf/logger.xml.

内容可能是:

<configuration>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%-5level - %msg%n</pattern>
        </encoder>
    </appender>

    <logger name="com.jolbox.bonecp" level="DEBUG">
        <appender-ref ref="STDOUT" />
    </logger>

    <logger name="play" level="DEBUG">
        <appender-ref ref="STDOUT" />
    </logger>

    <logger name="application" level="DEBUG">
        <appender-ref ref="STDOUT" />
    </logger>

</configuration>

com.jlbox.bonecp用于bonecp，play和application用于play2.

The com.jlbox.bonecp is for bonecp, and play and application are for play2.

注释application.conf中的记录器设置:

# Logger
# ~~~~~
# You can also configure logback (http://logback.qos.ch/), by providing a logger.xml file in the conf directory .

# Root logger:
# logger.root=ERROR

# Logger used by the framework:
# logger.play=INFO

# Logger provided to your application:
# logger.application=DEBUG

重新开始播放，您将看到所有已执行的SQL(包括参数值).

Restart play, and you will see all executed SQLs(including parameter values).
