HikariCP and maxLifetime

房东的猫 提交于 2019-12-04 06:53:49
I moved my project to HikariCP . Everything is going fine so far, but with one setting I'm having trouble. It's the .setMaxLifetime(30*1000) setting in HikariConfig object. I get this warning WARN com.zaxxer.hikari.HikariConfig - maxLifetime is less than 120000ms, using default 1800000ms. I know that they recommend not setting is that low as I am trying to. But Unfortunately due to circumstances that I can not change, every TCP connection that is open longer than 50 secods will be terminated in our production environment. i don't know your HikariCP Version, but in the version 2.2.4 you will

HikariCP Wrapper (thread safety)

[亡魂溺海] 提交于 2019-12-04 05:56:59
问题 I'm learning to use HikariCP (i'm new in java) and i found a wrapper but i think it's not thread safety, well the instance of the singleton is thread safety but not the method getConnection(). The class is this: public class HikariCPWrapper{ private static final HikariCPWrapper INSTANCE; private HikariDataSource ds; static { INSTANCE = new HikariCPWrapper(); } private HikariCPWrapper(){ HikariConfig config = new HikariConfig(); //config.set... //... ds = new HikariDataSource(config); } public

Configuration of JTDS for use with HikariCP + Spring + MS SQL Server

烂漫一生 提交于 2019-12-04 05:32:22
I kept googling for configuration of JTDS (1.3.1) for use with HikariCP (2.4.3), Spring (4.1.2), and MS SQL Server (2008), but unable to find a complete and working example. Here is what I have: <bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close"> <constructor-arg ref="hikariConfig" /> </bean> <bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig"> <property name="poolName" value="springHikariCP" /> <property name="connectionTestQuery" value="SELECT 1" /> <property name="dataSourceClassName" value="${jdbc.dataSourceClassName}" /> <property name=

spring boot添加非maven库里的jar包

笑着哭i 提交于 2019-12-04 05:03:08
日常开发用到的是oracle的jar包,但在maven中央库里没有;需要手动引包,但这样不利用项目以后的开发管理; 有一种方法是用maven install 命令将jar打成本地包, mvn install:install-file -DgroupId=com.zaxxer -DartifactId=HikariCP -Dversion=2.4.7 -Dpackaging=jar -Dfile=C:/Users/yangqc/Downloads/HikariCP-2.4.7.jar 另一种方式是配置maven打包机制,将工程中的jar中引入maven,打包时也引入打包资源中;这样算是彻底解决了问题; 工程目录 目录为src/main/lib,可根据个人习惯调整 引入依赖 <dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc7</artifactId> <version>12.1.0.2</version> <scope>system</scope> <systemPath>${basedir}/src/main/lib/ojdbc7-12.1.0.2.jar</systemPath> </dependency> 这里的scope和systemPath都不能少 pom改写 <build> <plugins>

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . I am trying to figure out the best approach for using hikaricp (JDBC connection pool) with microsoft sql server. From what I saw, the DataSource option is recommended (as is the case for most connection pools I've seen). However, I was not able to form a connection correctly with the sql server database based on

崛起于Springboot2.X + mysql读写分离升级版(22)

《SpringBoot2.X心法总纲》 介绍:之前写了一篇博客关于mysql的读写分离,那个需要配置多个类,如今读写分离升级了,我们不需要配置任何java配置文件类就可以,因为有人为我们封装了,我们只管添加依赖就好了。 注意:如果您看的不明白,可以去看下之前我写的读写分离,会发现简单很多, 读写分离Mysql 1、添加pom依赖 <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.1.10</version> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>dynamic-datasource-spring-boot-starter</artifactId> <version>1.4.0</version> </dependency> <dependency> <groupId>com.zaxxer</groupId> <artifactId>HikariCP</artifactId> <version>2.7.0</version> </dependency> 添加三个依赖,dynamic-datasource-spring
