Question

请告诉我。如何配置＆＃34; Hikari连接池+ Hibernate 4.3.8 + Spring Data JPA配置＆＃34;？这是我的配置，但由于某种原因，我确信这种配置不正确。因为控制台没有像＆＃34; connetction pooling＆＃34;那样出现。在互联网上，我找不到初学者的教程。感谢。

Answer 1

如果你想使用Hikari，你需要声明它，所以你的dataSource配置应该是

<bean id="dataSource"
    class="com.zaxxer.hikari.HikariDataSource">
    <property name="driverClassName" value="${dataSource.driverClassName}" />
    <property name="jdbcUrl" value="${dataSource.url}" />
    <property name="username" value="${dataSource.username}" />
    <property name="password" value="${dataSource.password}" />
</bean>

Answer 2

您的数据源配置应如下所示：

 <beans:bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource"  destroy-method="close">
                <beans:property name="dataSourceClassName" value="com.mysql.jdbc.jdbc2.optional.MysqlDataSource"/>
                <beans:property name="maximumPoolSize" value="5" />
                <beans:property name="maxLifetime" value="30000" />
                <beans:property name="idleTimeout" value="30000" />
                <beans:property name="dataSourceProperties">
                          <beans:props>
                              <beans:prop key="url">jdbc:mysql://localhost:3306/exampledb</beans:prop>
                              <beans:prop key="user">root</beans:prop>
                              <beans:prop key="password"></beans:prop>
                               <beans:prop key="prepStmtCacheSize">250</beans:prop>
                               <beans:prop key="prepStmtCacheSqlLimit">2048</beans:prop>
                               <beans:prop key="cachePrepStmts">true</beans:prop>
                               <beans:prop key="useServerPrepStmts">true</beans:prop>
                          </beans:props>
                </beans:property>
</beans:bean>

Answer 3

我们也可以在下面的定制JPAConfiguration类中使用它，您可以在其中建立连接并创建实体Manager Factory对象。

DECLARE @Columns_Updated VARCHAR(500)
DECLARE @Columns_Updated_Values AS NVARCHAR(500);
DECLARE @CUV_temp TABLE(value NVARCHAR (500))   
DECLARE @sqlQuery AS NVARCHAR(200) = 'SELECT CONCAT(' + REPLACE(@Columns_Updated,',',','','',') + ') from inserted';

INSERT INTO @CUV_temp
    EXEC(@sqlQuery) 

SELECT @Columns_Updated_Values = value 
FROM @CUV_temp

INSERT INTO Crm_Log (ModifedFields, ModifiedValues) 
    SELECT @Columns_Updated, @Columns_Updated_Values
