java - bean 类 [org.apache.commons.dbcp.BasicDataSource] 的属性 'connectionProperties' 无效

Question

我在初始化 BasicDataSource 时遇到此异常。我想将自定义连接属性传递给数据源。

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?

我用了this post from spring forum来解决问题。

添加这个 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>
