SpringBoot怎么集成P6Spy实现SQL日志-java教程-PHP中文网

P6Spy简介

P6Spy是一个可以用来在应用程序中拦截和修改数据操作语句的开源框架。

通过P6Spy可以对SQL语句进行拦截，相当于一个SQL语句的记录器，这样我们可以用它来作相关的分析，比如性能分析。

应用场景

mybatis-plus也可以打印输出的sql日志，但是不是我们想要的效果，如何来控制想要的sql日志输出，可以使用P6Spy开源产品。

SpringBoot怎么集成P6Spy实现SQL日志

P6Spy入门使用

spy.properties

resources目录添加配置文件，类似log4j.xml，记录配置信息

module.log=com.p6spy.engine.logging.P6LogFactory,com.p6spy.engine.outage.P6OutageFactory
# sql日志打印输出
# 1、logMessageFormat=com.p6spy.engine.spy.appender.SingleLineFormat
# 2、logMessageFormat=com.p6spy.engine.spy.appender.CustomLineFormat
# customLogMessageFormat=%(currentTime) | SQL use time: %(executionTime) ms | connect info: %(category)-%(connectionId) | execute sql: %(sql)
# 3、自定义日志打印(全限定类名)
logMessageFormat=cn.zysheep.config.P6SPYConfig
# 使用日志系统记录sql
appender=com.p6spy.engine.spy.appender.Slf4JLogger
## 配置记录Log例外
excludecategories=info,debug,result,batc,resultset
# 设置使用p6spy driver来做代理
deregisterdrivers=true
# 日期格式
dateformat=yyyy-MM-dd HH:mm:ss
# 实际驱动
driverlist=com.mysql.cj.jdbc.Driver
# 是否开启慢SQL记录
outagedetection=true
# 慢SQL记录标准秒
outagedetectioninterval=2

P6Spy有内置的SQL输出格式，如上配置文件。这里我们使用自定义SQL日志打印

P6SPYConfig

public class P6SPYConfig implements MessageFormattingStrategy { @Override public String formatMessage(int connectionId, String now, long elapsed, String category, String prepared, String sql, String url) { Map message = new LinkedHashMap<>(8); String newPrepared = prepared.replace(" ", "").replace("\n", " "); message.put("prepared", newPrepared); String newSql = sql.replace(" ", "").replace("\n", " "); message.put("sql", newSql); return JSONObject.toJSONString(message, true); } }

登录后复制

application.yml

spring:
datasource:
# driver-class-name: com.mysql.cj.jdbc.Driver
driver-class-name: com.p6spy.engine.spy.P6SpyDriver
type: com.alibaba.druid.pool.DruidDataSource
# url: jdbc:mysql://localhost:3306/course_db?serverTimezone=GMT%2B8
url: jdbc:p6spy:mysql://localhost:3306/course_db?serverTimezone=GMT%2B8

# 打开mybatis-plus的sql日志输出
mybatis-plus:
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
