我们已经将 spring boot(v1.5.1)-jpa 应用程序配置为指向 HikariCP，但由于一些奇怪的原因，应用程序仍然指向 tomcat-jdbc 池，这是 spring-boot 使用的默认值，而不是 Hikari-CP。我已经提到了下面使用的配置。

更新
现在当 HikariCP 尝试加载时进行更改后，我们得到 SQLNotSupportedFeature 异常。请注意，我们将 Springboot-JPA-Hibernate 与 hikari 结合使用。

任何帮助表示赞赏。

应用程序属性

hibernate.show.sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Oracle10gDialect
spring.datasource.hikari.maximum-pool-size=50
spring.datasource.hikari.idle-timeout=1000
spring.datasource.hikari.pool-name=pooool
spring.datasource.type=com.zaxxer.hikari.HikariDataSource

spring.datasource.url=jdbc:oracle:thin:@<hostname>:1521/<instance>
spring.datasource.username=<user>
spring.datasource.password=<password>
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver

数据配置

我们使用 Spring JPA 休眠组合以及 PCF（Pivotal Cloud Foundry）进行配置。

        public class DataSourceConfiguration {

            @Value("${spring.datasource.hikari.maximum-pool-size}")
            private int maxSize;

            @Value("${spring.datasource.hikari.idle-timeout}")
            private String idleTimeout;

            @Value("${spring.datasource.username}")
            private String username;

            @Value("${spring.datasource.password}")
            private String password;

            @Value("${spring.datasource.url}")
            private String url;

            @Value("${spring.datasource.driver-class-name}")
            private String driverClassName;

            @Bean("destroyMethod=close")
            @Primary
            public DataSource dataSource() {
                HikariDataSource dataSource = new HikariDataSource();
                dataSource.setUrl(url);
                dataSource.setPassword(password);
                dataSource.setUsername(username);
                dataSource.setDriverClassName(driverClassName);
                dataSource.setValidationQuery(idleTimeout);
                dataSource.setMaxIdle(maxSize);
                return dataSource;
            }

            @Bean
            public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource) {
                System.err.println("POOLSIZE----> " +dataSource.getPoolSize());
                System.err.println("POOLNAME----> " +dataSource.getName());
                    LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
                    entityManagerFactoryBean.setDataSource(dataSource);
                    entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
                    entityManagerFactoryBean.setPackagesToScan(applicationPropertiesConfig.getPackagestoScan());

                    Properties jpaProperties = new Properties();
                    jpaProperties.put("hibernate.dialect", applicationPropertiesConfig.getHibernateDialect());
                    jpaProperties.put("hibernate.show_sql", applicationPropertiesConfig.getHibernateShowSQL());
                    entityManagerFactoryBean.setJpaProperties(jpaProperties);
                    return entityManagerFactoryBean;
            }

            /**
             * Declaration of the transaction manager.
             *
             * @param entityManagerFactory the entity manager factory
             * @return an instance of JpaTransactionManager
             */
            @Bean
            JpaTransactionManager transactionManager(EntityManagerFactory entityManagerFactory) {
                    JpaTransactionManager transactionManager = new JpaTransactionManager();
                    transactionManager.setEntityManagerFactory(entityManagerFactory);
                    return transactionManager;
            }

请帮忙，因为这会阻止我们的应用程序并且令人沮丧。提前致谢。

您的 gradle 应该具有以下 hikari 配置：

configurations {
     compile.exclude module: "tomcat-jdbc"
}

dependencies {
     compile("org.springframework.boot:spring-boot-starter-jdbc")
     compile group: 'com.zaxxer', name: 'HikariCP', version: '2.6.3'
}

以上将排除 tomcat-jdbc 并将使用 hikari 创建连接池。希望这会有所帮助。

你应该new HikariDataSource(.....)而不是new DataSource()在你的 bean 中。
