Spring

Question

我正在尝试使用基于 xml 的 bean 配置为基于 spring 的应用程序使用 Hikari 连接池。下面是我的 Hikari 配置 bean，我使用 Db2 作为我的数据库。

<bean id="HikariConfig_UId_Primary" class="com.zaxxer.hikari.HikariConfig">
    <property name="poolName" value="uidPrimaryCP" />
    <property name="connectionTestQuery" value="select 1 from sysibm.systables fetch first row only with UR" />
    <property name="dataSourceClassName" value="${Jdbc_DataSourceClassName}" />
    <property name="maximumPoolSize" value="${Jdbc_MaxPoolSize}"/>
    <property name="idleTimeout" value="${Jdbc_IdleTimeOut}" />
    <property name="maxLifetime" value="${Jdbc_MaxLifeTime}" />
    <property name="connectionTimeout" value="${Jdbc_ConnTimeOut}" />

    <property name="dataSourceProperties">
        <props>
            <prop key="url">${Jdbc_UID_Primary}</prop>
            <prop key="user">${Jdbc_UserId}</prop>
            <prop key="password">${Jdbc_Password}</prop>
        </props>
    </property>
    </bean>

<bean id="UID_Primary_DataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close">
    <constructor-arg ref="HikariConfig_UId_Primary" />
    </bean>

它无法注册 bean，说数据库 url 属性 - url 在目标 class com.ibm.[=22 上不存在=].DB2SimpleDataSource。下面是完整的堆栈跟踪..

非常感谢任何帮助..

谢谢..

Answer 1

我已经使用 spring 引导连接到 Hikari，但没有使用 xml 配置。看我的post

我想，在属性下面加起来应该可以解决错误。

<property name="jdbcUrl" value="" />
<property name="username" value="" />
<property name="password" value="" />

Answer 2

你好像有几处地方不对。您没有 post 变量 ${Jdbc_DataSourceClassName} 的值，因为它似乎在运行时解析为 DB2SimpleDataSource。每 this IBM KnowledgeCenter topic, that datasource is not poolable and since you started the post with "I am trying to use Hikari connection pooling", I'm assuming you want a poolable DS like com.ibm.db2.jcc.DB2ConnectionPoolDataSource as described here。第二个问题是 DB2 数据源类不支持 url 属性，只有 DB2 DriverManager 接口支持它。 DB2数据源抽象基础的KC题目类，DB2BaseDataSource，说

You can set all properties on a DataSource or in the url parameter in a DriverManager.getConnection call.

url 不是列出的属性之一，因此您需要使用主机名、端口等属性建立与数据源的连接
