Bean类[org.apache.commons.dbcp.BasicDataSource]的无效属性'connectionProperties'

Question

初始化BasicDataSource时遇到此异常。 我想将自定义连接属性传递给dataSource。

我的配置是：

Caused by: org.springframework.beans.NotWritablePropertyException: Invalid property 'connectionProperties' of bean class [org.apache.commons.dbcp.BasicDataSource]: Bean property 'connectionProperties' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

我使用了来自spring论坛的帖子来解决此问题。

添加此bean解决了我的问题。

<bean
    class="org.springframework.beans.factory.config.MethodInvokingFactoryBean"
    lazy-init="false">
    <property name="targetObject" ref="csdbDataSource" />
    <property name="targetMethod" value="addConnectionProperty" />
    <property name="arguments">
        <list>
            <value>defaultRowPrefetch</value>
            <value>1</value>
        </list>
    </property>
</bean>
