使用P6Spy格式化SQL语句

公司最近在做一个项目,开发过程中遇到点小问题，查询结果出不来，查看自带日志打印，有点不爽，特别是想复制sql语句到数据库navicat中去调试时，还要手动复制参数值，很是麻烦，那如果想打印出格式化的详细sql语句,我们该如何做呢?

一、pom.xml文件中添加依赖：

<dependency>
    <groupId>p6spy</groupId>
    <artifactId>p6spy</artifactId>
</dependency>

二、在profiles下的local和dev中加入spy.properties文件，配置自定义输出格式：
主要是指定数据库驱动（日期格式化、使用单行还是多行），指定输出方式控制台、log文件等）

# If you are using the DataSource support outside of an app     #

# jndicontextfactory and jndicontextproviderurl. If you need    #
# additional elements, use the jndicontextcustom property.      #
# You can define multiple properties in jndicontextcustom,      #

# Outage Detection
#
# This feature detects long-running statements that may be indicative of
# a database outage problem. If this feature is turned on, it will log any
# statement that surpasses the configurable time boundary during its execution.
# When this feature is enabled, no other statements are logged except the long
# running statements. The interval property is the boundary time set in seconds.
# For example, if this is set to 2, then any statement requiring at least 2
# seconds will be logged. Note that the same statement will continue to be logged
# for as long as it executes. So if the interval is set to 2, and the query takes
# 11 seconds, it will be logged 5 times (at the 2, 4, 6, 8, 10 second intervals).
#
# outagedetection=true|false
# outagedetectioninterval=integer time (seconds)

三、数据库datasource.xml：

    <!--数据库连接设置-->
    <bean id="dataSource" class="com.p6spy.engine.spy.P6DataSource">
        <constructor-arg>
            <ref bean="dataSourceDefault"/>
        </constructor-arg>
    </bean>

四、local下的log4j.properties文件添加代码（红框里的为新加代码）：

五、初次运行效果：

#####-----1504860808714|2|statement|connection 0|SELECT         *         FROM         t_course c         LEFT JOIN t_teacher_course tc ON tc.course_id =c.id         LEFT JOIN t_training_programs tp ON tp.course_id=c.id         WHERE         tp.semester_id = ? AND tp.grade = ? AND tc.teacher_id = ?         AND c.is_delete = 0 AND tc.is_delete = 0 AND tp.is_delete = 0|SELECT         *         FROM         t_course c         LEFT JOIN t_teacher_course tc ON tc.course_id =c.id         LEFT JOIN t_training_programs tp ON tp.course_id=c.id         WHERE         tp.semester_id = 'YVMEMS37M5KWYDM7LXEX01' AND tp.grade = '2013级' AND tc.teacher_id = '06493cbbdf79f909d6ab0a'         AND c.is_delete = 0 AND tc.is_delete = 0 AND tp.is_delete = 0

但是这样的结果，我们还是不太清晰，P6SpyLogger打印的不该是这样的格式，后来发现是tool里的jar包没有下载，于是：

1、在资源管理器中打开代码，按shift+鼠标右键，打开命令窗口：

2、命令窗口中输入：mvn compile -U，强制下载tool里jar包：

六、最终运行结果：

#####-----2017-09-08 16:59:16:358 | took 3ms | statement | connection 0
 SELECT
        *
        FROM
        t_course c
        LEFT JOIN t_teacher_course tc ON tc.course_id =c.id
        LEFT JOIN t_training_programs tp ON tp.course_id=c.id
        WHERE
        tp.semester_id = 'YVMEMS37M5KWYDM7LXEX01' AND tp.grade = '2013级' AND tc.teacher_id = '06493cbbdf79f909d6ab0a'
        AND c.is_delete = 0 AND tc.is_delete = 0 AND tp.is_delete = 0;

这样我们就可以直观看出sql语句，直接到navicat测试了，怎么样，这样是不是很方便，快来试试吧！
