Why is 'SHOW WARNINGS' query issued here? (JPA/Hibernate/MySQL)

由 ☆樱花仙子☆ 提交于 2019-12-07 05:37:34
问题 We are refactoring the persistence layer of a Java application from JDBC Template to JPA/Hibernate. I am profiling the SQL statements being issued to the database and I see "SHOW WARNINGS" is issued many, many times. According to JProfiler the "SHOW WARNINGS" is accounting for a considerable amount of 'inherent time'. What could cause SHOW WARNINGS to be issued so frequently? This SHOW WARNINGS was NOT previously issued when using Jdbc Template. Below is the part of our stack relevant to

问题 I have a SpringBoot app, I was making some performance test in the controller, and I realized that whatever is the first query I put the controller, It take ages compare to the others... (ths DB is a remote connection, but I can't change this) long t1 = System.nanoTime(); menuPriceSummaryService.findAllVegan().stream(); long t2 = System.nanoTime(); long elapsedTimeInSeconds = (t2 - t1) / 1000000000; System.out.println("elapsedTimeInSeconds1 -> " + elapsedTimeInSeconds); t1 = System.nanoTime()

SpringBoot数据访问 关系型数据库访问 1.连接池 dbcp2、c3p0、druid、HikariCP、proxool等 依赖连接池jar包、驱动的jar包 spring-boot-starter-jdbc默认会追加连接池(1.x tomcat-jdbc 2.x hikaricp) application.properties或者application.yml中配置 数据库连接参数 在启动类开启自动配置@SpringBootApplication DataSourceAutoConfiguration自动配置组件规则: 默认按创建Hikari，然后tomcat，dbcp2顺序执行 如果需要创建指定类型连接池，可以采用下面配置 spring.datasource.type=xxx，或者从jdbc中把hikaricpjar包删除调 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> <exclusions> <exclusion> <groupId>com.zaxxer</groupId> <artifactId>HikariCP</artifactId> </exclusion> </exclusions> <

HikariCP and maxLifetime

由 北城余情 提交于 2019-12-06 02:51:08
问题 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
