通过Spring xml数据源配置postgresql驱动程序 [英] Configuring postgresql driver through Spring xml datasource

问题描述

我一直在尝试配置使用xml Spring配置文件中声明的postgresql数据源建立的连接。

I've been trying to configure the connections made with a postgresql datasource declared in a xml Spring configuration file.

<bean id="myDataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="org.postgresql.Driver" />
        <property name="url" value="jdbc:postgresql://localhost:5432/dbname" />
        <property name="username" value="postgres" />
        <property name="password" value="" />
        <property name="socketTimeout" value="10"/>
    </bean>

我知道，我不应该使用 DriverManagerDataSource 类从春季开始，（我们很快将移至C3p0或DBCP），因为它不是真正的池。
我正在尝试设置postgresql连接的socketTimeout值（在此处 https中进行描述：//jdbc.postgresql.org/documentation/head/connect.html ），但是当然， socketTimeout不是数据源的属性，因此它不起作用。

I know, I shouldn't be using the DriverManagerDataSource class from spring, (we will soon move to C3p0 or DBCP) because it's not a real pooling. I'm trying to set the socketTimeout value of a postgresql connection ( described here https://jdbc.postgresql.org/documentation/head/connect.html ) but of course, "socketTimeout" is not a property of the datasource, so it doesn't work.

是否可以通过数据源xml的配置来做到这一点？还是我应该在其他地方做？因为数据源管理连接，所以我认为我无法执行

Is it possible to do this through the datasource xml's configuration ? Or should I do it somewhere else ? Because the data source manages the connection I don't think I'll be able to do a

props.setProperty("timeout",30);
Connection conn = DriverManager.getConnection(url, props);

我什至可以使用DriverManagerDataSource做到这一点吗？我尝试搜索，但是没有找到任何有用的东西，因为没有很多人真正使用它。

Can I even do this with the DriverManagerDataSource ? I tried to search, but I didn't find anything usefull, as not a lot of people are really using it.

推荐答案

谢谢Deinum先生，我能够找到方法。
实际上，即使知道该属性的名称为 connectionProperties，我也没有找到很多答案（也许人们很少以这种方式使用它？）。因此，我将其发布：

Thank you M. Deinum, I was able to find how. Actually, even knowing the property was named "connectionProperties", I didn't found a lot answers (maybe people rarely use it this way ?). So I'm posting it:

<bean id="myDataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="org.postgresql.Driver" />
        <property name="url" value="jdbc:postgresql://localhost:5432/dbname" />
        <property name="username" value="postgres" />
        <property name="password" value="" />
        <!--<property name="socketTimeout" value="10"/>-->

        <property name="connectionProperties">
            <props>
                <prop key="socketTimeout">10</prop>
            </props>
        </property>
   </bean>

如果有人有更好/更完整的答案，我会检查出来;）

If anyone has a better/more complete answer, I'll check it out ;)
