spring boot应用p6spy监控sql

Spring boot中使用p6spy监控hibernate sql语句值

开发环境

• 开发工具：IDEA
• 开发环境：spring mvc、spring boot、spring data
• 数据库:mysql

具体步骤如下：

• pom.xml中添加p6spy包依赖：

        <dependency>
            <groupId>p6spygroupId>
            <artifactId>p6spyartifactId>
            <version>3.0.0version>
        dependency>

• application.yml配置中：

(1). url中必须增加p6spy,才能对SQL进行拦截：

jdbc:p6spy:mysql://192.0.6.116:3066/testdb

(2). driver-class需替换为：

com.p6spy.engine.spy.P6SpyDriver

具体如下：

spring:
  datasource:
    url: jdbc:p6spy:mysql://192.0.6.116:3066/testdb
    #driver-class-name: com.mysql.jdbc.Driver
    driver-class-name: com.p6spy.engine.spy.P6SpyDriver
    username: root
    password: xxxxxx

• 将spy.properties放到resources根目录下

spy.properties文件内容参考如下：

# If you are using the DataSource support outside of an app     #
# server, you will probably need to define the JNDI Context     #
# environment.                                                  #

# If the P6Spy code will be executing inside an app server then #
# do not use these properties, and the DataSource lookup will   #
# use the naming context defined by the app server.             #
#                                                               #
# The two standard elements of the naming environment are       #
# jndicontextfactory and jndicontextproviderurl. If you need    #
# additional elements, use the jndicontextcustom property.      #
# You can define multiple properties in jndicontextcustom,      #
# in name value pairs. Separate the name and value with a       #
# semicolon, and separate the pairs with commas.                #

# a machine that is also running JBoss, so the JDNI context     #

# 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)
#
# (default is false)
#outagedetection=false
# (default is 60)
#outagedetectioninterval=30

其中spy.properties文件中的logMessageFormat可以使用自定义类，自定义输出格式：

logMessageFormat=com.aellelib.common.utils.P6LogFormat

P6LogFormat类代码如下：

package com.aellelib.common.utils;

import com.p6spy.engine.common.P6Util;
import com.p6spy.engine.spy.appender.SingleLineFormat;
import org.hibernate.engine.jdbc.internal.BasicFormatterImpl;

/**

 */
public class P6LogFormat extends SingleLineFormat {
    private static BasicFormatterImpl formatter = new BasicFormatterImpl();
    private int i = 0;

    @Override
    public String formatMessage(int connectionId, String now, long elapsed, String category, String prepared, String sql) {
        if (i == 0) {
            i++;
            return now + "|" + "" + elapsed + "|"  + "" + category + "|connection " + "" + connectionId + "|" + "\nAfter Prepared SQL:" +
            formatter.format(P6Util.singleLine(prepared)) + "\nBefore Prepared SQL:" + formatter.format(P6Util.singleLine(sql));
        } else {
            i =  0;
            return now + "|" + category + "|" + "Time Consumin:" + elapsed + "ms";
        }
    }
}
