Question

我正在使用：

Spring 4.1.4.RELEASE
Hibernate 4.3.8.FINAL
HikariCP 2.3.2
MySQL 5.6.22 Homebrew

HikariCP 页面有两篇关于MySQL和Hibernate的有趣文档/博客

之后阅读以下关于MySQL的教程：

MySQL Configuration

我有关于DataSource的以下配置：

Alpha （最佳推荐和首次尝试）

@Bean(name="dataSource", destroyMethod="close")
public DataSource dataSourceDevelopment() throws Exception{

    HikariConfig hc = new HikariConfig();
    hc.setDataSourceClassName("com.mysql.jdbc.jdbc2.optional.MysqlDataSource");
    //hc.setDriverClassName("com.mysql.jdbc.Driver");
    //hc.setJdbcUrl("jdbc:mysql://localhost:3306/manolodb_01");
    hc.setUsername("user");
    hc.setPassword("password");
    hc.setPoolName("hikaricp-manolodb_01-pool");
    hc.addDataSourceProperty("databaseName", "manolodb_01");
    hc.addDataSourceProperty("cachePrepStmts", "true");
    hc.addDataSourceProperty("prepStmtCacheSize", "250");
    hc.addDataSourceProperty("prepStmtCacheSqlLimit", "2048");
    hc.addDataSourceProperty("useServerPrepStmts", "true");

    HikariDataSource hds = new HikariDataSource(hc);        
    return hds;
}

之后阅读以下有关Hibernate的教程：

Hibernate4

我有以下配置：

@Bean
public LocalSessionFactoryBean sessionFactory(DataSource dataSource){

    LocalSessionFactoryBean localSessionFactoryBean = new LocalSessionFactoryBean();

    localSessionFactoryBean.setDataSource(dataSource);
    localSessionFactoryBean.setPackagesToScan("com.manuel.jordan.domain");

    Properties hibernateProperties = new Properties();
    hibernateProperties.setProperty("hibernate.dialect", environment.getRequiredProperty("database.hibernate.dialect", String.class));
    hibernateProperties.setProperty("hibernate.connection.provider_class","com.zaxxer.hikari.hibernate.HikariConnectionProvider");
    hibernateProperties.setProperty("hibernate.cache.provider_class","org.hibernate.cache.NoCacheProvider");
    hibernateProperties.setProperty("hibernate.show_sql","true");
    hibernateProperties.setProperty("hibernate.format_sql","true");
    hibernateProperties.setProperty("hibernate.use_sql_comments","true");
    hibernateProperties.setProperty("hibernate.max_fetch_depth","30");
    hibernateProperties.setProperty("hibernate.default_batch_fetch_size","30");
    hibernateProperties.setProperty("hibernate.jdbc.batch_size","30");//N + 1
    hibernateProperties.setProperty("hibernate.order_updates", "true");

    hibernateProperties.setProperty("org.hibernate.SQL","true");
    hibernateProperties.setProperty("org.hibernate.type","true");


    localSessionFactoryBean.setHibernateProperties(hibernateProperties);

    return localSessionFactoryBean;

}

观察我正在使用： hibernateProperties.setProperty("hibernate.connection.provider_class","com.zaxxer.hikari.hibernate.HikariConnectionProvider");

但我总是收到：

Caused by: java.lang.IllegalArgumentException: one of either dataSource or dataSourceClassName must be specified
    at com.zaxxer.hikari.AbstractHikariConfig.validate(AbstractHikariConfig.java:747)
    at com.zaxxer.hikari.HikariDataSource.<init>(HikariDataSource.java:73)
    at com.zaxxer.hikari.hibernate.HikariConnectionProvider.configure(HikariConnectionProvider.java:80)
    ... 54 more

即使 Beta

@Bean(name="dataSource", destroyMethod="close")
public DataSource dataSourceDevelopment() throws Exception{

    HikariConfig hc = new HikariConfig();
    //hc.setDataSourceClassName("com.mysql.jdbc.jdbc2.optional.MysqlDataSource");
    hc.setDriverClassName("com.mysql.jdbc.Driver");
    hc.setJdbcUrl("jdbc:mysql://localhost:3306/manolodb_01");
    hc.setUsername("user");
    hc.setPassword("password");
    hc.setPoolName("hikaricp-manolodb_01-pool");
    hc.addDataSourceProperty("databaseName", "manolodb_01");
    hc.addDataSourceProperty("cachePrepStmts", "true");
    hc.addDataSourceProperty("prepStmtCacheSize", "250");
    hc.addDataSourceProperty("prepStmtCacheSqlLimit", "2048");
    hc.addDataSourceProperty("useServerPrepStmts", "true");

    HikariDataSource hds = new HikariDataSource(hc);        
    return hds;
}

我收到相同的错误消息：

我确实意识到我是否发表评论

hibernateProperties.setProperty("hibernate.connection.provider_class","com.zaxxer.hikari.hibernate.HikariConnectionProvider");

我有没有错误。为什么会出现这种情况？

我认为我的配置正确，因为第二个链接说：

In order to use the HikariConnectionProvider in Hibernate 4.x add the    
following property to your hibernate.properties configuration file:

hibernate.connection.provider_class=com.zaxxer.hikari.hibernate.HikariConnectionProvider

这就是我所拥有的......

我不想直接在hibernate.properties中包含HikariCP配置属性，第二个链接也是如此。

Answer 1

您可以使用2个选项配置DataSource以便与hibernate一起使用，或者在spring中完全配置DataSource并将其注入dataSource的{{1}}属性或您使用hibernate属性来配置LocalSessionFactoryBean，在这种情况下，您必须设置DataSource。

Hiknate与Hibernate和MySql：必须指定dataSource或dataSourceClassName之一
