when using DataSource to initialize the JDBC adapter to use Jcasbin, it's OK at first several hours. However, when it takes long enough, problem happens. It cannot connect to Database, I try to solve the problem according the log hint., I tried:

  1. set spring.datasource.hikari.validationTimeout = 300000 for application
  2. add &autoReconnect=true to jdbcUrl but it doesn't works at all.

Here is the my environment and library version:

<dependency>
      <groupId>org.casbin</groupId>
      <artifactId>jdbc-adapter</artifactId>
      <version>2.0.1</version>
  </dependency>
  <dependency>
      <groupId>org.casbin</groupId>
      <artifactId>jcasbin</artifactId>
      <version>1.6.0</version>
  </dependency>
  <dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
         <version>8.0.25</version>
  </dependency>
  <dependency>
    <groupId>com.zaxxer</groupId>
    <artifactId>HikariCP</artifactId>
        <version>4.0.3</version>
  </dependency>

Here is how I initialize the JDBC adapter:

  @Bean
  fun enforcer(
      properties: CasbinProperties,
      dataSource: DataSource
  ): EnforcerExt {
      val jdbcAdapter = JDBCAdapter(dataSource)
      val model = Model()
      val enforcer = Enforcer(model, jdbcAdapter)
      enforcer.enableAutoSave(false)
      enforcer.enableEnforce(properties.enable)
      return enforcer
 }

Here is the Error Log:

@PSilverQ autoReconnect=true doesn't apply to mysql8 and it is not officially recommended. mysql8 disconnects after 8 hours by default. Maybe you can try to set other config for hikari such as

spring.datasource.hikari.connection-test-query=SELECT 1
spring.datasource.hikari.connection-timeout=30000
spring.datasource.hikari.idle-timeout=60000
spring.datasource.hikari.max-lifetime=540000

I think this doesn't belong to the jdbc-adapter's problem

Thanks, It may not belong to the jdbc-adapter. Actually, I'm not sure. I used JPA and Jcasbin-adapter whith the same HikariCP DateSource and Mysql5.7 server, but the JPA never encounter the problem，It's puzzled. It is probable that JPA has Retry mechanism or someway else to avoid problem when it obtain a dead connection from datasource. It looks like that the jdbc-adapter dosen't implement such retry mechanism .

My team have a strict requirement that I must use HikariCP. Just recently my team decide to use PGSQL to replace MySQL to use some no SQL feature, so I may not have to solve this * Mysql 8 Hour Problem**.

Thanks anyway

I also encountered this problem

hsluoyz commented 3 years ago

@GodfreyGuo can you give more details?

pizhicheng commented 2 years ago

Same problem. When i use autowired datasource as the the parameter of JDBCAdapter constructor, several hours later all operation will throw exception Connection is closed.

hsluoyz commented 2 years ago

@seriouszyx can you follow up this issue?

seriouszyx commented 2 years ago

@pizhicheng Actually we implemented the retry mechanism in the latest PR #43 , can you give us your jdbc-adapter version and more details about the exception?

pizhicheng commented 2 years ago

Ok, i see. I used the same version with this issue creator - 2.0.1. I'll try the latest version.
