Postgres Spring数据JPA休眠中的间歇性关闭连接

Question

我经常间歇性地遇到这个问题。

我们已经配置了

支持的Spring Boot项目

1. spring-boot-starter-data-jpa（1.5.3.RELEASE），
2. spring-data-jpa（1.11.3.RELEASE），
3. hibernate-core（5.0.12.Final），
4. org.postgresql：postgresql：9.4.1212.jre7
5. org.apache.tomcat：tomcat-jdbc：8.5.14

postgres => SELECT version（）;

版本

PostgreSQL 11.1 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28), 64-bit

（1行）

org.apache.tomcat.jdbc.pool.DataSource是从包含以下数据源属性的application.yml中填充的

spring:
 tomcat:
  removeAbandoned: true
  removeAbandonedTimeout: 120
  logAbandoned: true
  maxActive: 50
  maxIdle: 5
  maxWait: 1000
  validationQuery: "select 1"
  testOnBorrow: true
  testOnConnect: true
  testWhileIdle: true

我们间歇性地遇到以下连接关闭问题，当我们重新启动服务时，该问题已得到纠正。

我发现以下问题无用Intermittent Java PostgreSQL Connection closed

对此将提供任何帮助。
