Hikari最大池大小不受DataSourceBuilder的影响

Question

我是springboot和JPA世界的新手。我的应用程序出现问题，maximum-pool-size没有更新。始终为10。为什么总是采用默认值？

下面是我的application.yml

  spring:
  profiles: uat

  datasource:
    platform: oracle
    initialization-mode: never
    driverClassName: xxx.xx.xx
    url: xxx
    username: xxx
    password: xxx

    hikari.connection-timeout: 20000
    hikari.minimum-idle: 5
    hikari.maximum-pool-size: 15
    hikari.idle-timeout: 300000
    hikari.max-lifetime: 1200000

我添加了hikari.maximumPoolSize: 100，但输出仍然相同10

下面是配置Bean。

     @EnableJpaRepositories( basePackages = {
            "entityjar.XX", "com.XXX"}, repositoryFactoryBeanClass = EnversRevisionRepositoryFactoryBean.class )
       @EnableTransactionManagement
       @EnableEncryptableProperties
    public class DatabaseConfig
    {
        @Autowired
        private Environment env;

        @Bean
        @Primary
        @ConfigurationProperties( "spring.datasource" )
        public DataSourcePropertie

s dataSourceProperties()
    {
        return new DataSourceProperties();
    }

    @Bean( name = "dataSource", destroyMethod = "close" )
    public DataSource dataSource()
    {
        String usr = env.getProperty( "spring.datasource.username" );
        String pwd = env.getProperty( "spring.datasource.password" );

        usr = StringUtils.isNotBlank( usr ) ? usr : getValueFromCredStash( "datasource.username" );
        pwd = StringUtils.isNotBlank( pwd ) ? pwd : getValueFromCredStash( "datasource.password" );

        String url = env.getProperty( "spring.datasource.url" ); 

        final DataSourceBuilder factory = DataSourceBuilder.create().username( usr ).password( pwd )
                .url( url );

        final DataSource dsc = factory.build();

        return dsc;
    }

启动tomcat时的日志输出

Answer 1

您可以使用Spring Boot中提供的这些属性：

spring.datasource.hikari.minimumIdle=5
spring.datasource.hikari.maximumPoolSize=8

然后：

spring.datasource.hikari.idleTimeout=120000

为了限制空闲连接的寿命，但是hikari没有为您提供初始连接数的此类属性。

您必须将minimum-idle更改为minimumIdle，并将maximum-pool-size更改为maximumPoolSize

如果是application.yaml

 hikari:
      minimumIdle: 10
      maximumPoolSize: 20
      connectionTimeout: 50000
      leak-detection-threshold: 45000
