如何在Spring（4）上下文中为HSQL配置Hikari CP？ [英] How to configure Hikari CP for HSQL in a Spring(4) context?

问题描述

我想在我的Spring 4.0.3环境中使用 Hikari CP ，但似乎我遗漏了一些东西。

i want to use Hikari CP in my Spring 4.0.3 context but seems i am missing something.

我的bean配置如下：

My bean configuration looks like:

<bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource">
   <constructor-arg>
     <bean class="com.zaxxer.hikari.HikariConfig">
       <constructor-arg>
         <props>
           <prop key="dataSource.driverClassName">${database.driver}</prop>
           <prop key="dataSource.jdbcUrl">${database.database.jdbc.url}</prop>
           <prop key="dataSource.port">${database.port}</prop>
           <prop key="dataSource.databaseName">${database.name}</prop>
           <prop key="dataSource.user">${database.user}</prop>
           <prop key="dataSource.password">${database.password}</prop>
         </props>
       </constructor-arg>

     </bean>
   </constructor-arg>
</bean>

但我得到一个例外：

Caused by: java.lang.IllegalArgumentException: one of either dataSource or dataSourceClassName must be specified
    at com.zaxxer.hikari.HikariConfig.validate(HikariConfig.java:655)
    at com.zaxxer.hikari.HikariDataSource.<init>(HikariDataSource.java:66)

    at org.springframework.beans.BeanUtils.instantiateClass(BeanUtils.java:148)
    ... 15 more

我试图使用HSQL配置dataSourceClassName org.hsqldb.jdbc.JDBCDataSource

i have tried to configure dataSourceClassName using the HSQL org.hsqldb.jdbc.JDBCDataSource

这样：

<prop key="dataSourceClassName">org.hsqldb.jdbc.JDBCDataSource</prop>

同样如此：

<prop key="dataSource.ClassName">org.hsqldb.jdbc.JDBCDataSource</prop>

两次我都得到以下例外：

both times i got the following exception:

Caused by: java.lang.RuntimeException: java.beans.IntrospectionException: Method not found: setPort
    at com.zaxxer.hikari.util.PropertyBeanSetter.setProperty(PropertyBeanSetter.java:109)
    at com.zaxxer.hikari.util.PropertyBeanSetter.setTargetFromProperties(PropertyBeanSetter.java:61)
    at com.zaxxer.hikari.pool.HikariPool.initializeDataSource(HikariPool.java:497)
    ... 23 more

有人能给我看一个 Hikari CP Spring 4 bean配置，可以与HSQL DB一起使用吗？

Can someone show me a working Hikari CP Spring 4 bean configuration that works with a HSQL DB?

我不感兴趣在MySql，PG等中，因为我知道如何让它们工作。但我无法通过HSQL完成它。

I am not interested in MySql, PG etc. because i know how to get them working. But i can't manage to get it done with HSQL.

谢谢，

推荐答案

完成工作的一种方法是提供DataSource对象的实例：

one way to get the job done is to provide an instance of a DataSource object:

<bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource">
  <constructor-arg>
    <bean class="com.zaxxer.hikari.HikariConfig">
      <property name="dataSource">
        <bean class="org.hsqldb.jdbc.JDBCDataSource">
          <property name="url" value="${database.database.jdbc.url}"/>
          <property name="databaseName" value="${database.name}"/>
          <property name="user" value="${database.user}"/>
          <property name="password" value="${database.password}"/>
        </bean>
      </property>
    </bean>
  </constructor-arg>
</bean>

肯定还有其他解决方案。

for sure there are other solutions.
