Question

Tomcat 7サーバーに2つのSpring Rooアプリケーションをデプロイしました。私は例外

Cannot create JDBC driver of class 'org.postgresql.Driver' for connect URL 'postgres://username:password@localhost:5432/db' 
java.sql.SQLException: No suitable driver

私は私の問題を解決する方法をアドバイスしてください。..

Answer 1

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"  destroy-method="close"> 
    <property name="driverClass" value="org.postgresql.Driver" /> 
    <property name="jdbcUrl" value="jdbc:postgresql://localhost:5432/db" /> 
    <property name="user" value="user" /> 
    <property name="password" value="pass" /> 
    <!-- pool sizing --> 
    <property name="initialPoolSize" value="3" /> 
    <property name="minPoolSize" value="6" /> 
    <property name="maxPoolSize" value="25" /> 
    <property name="acquireIncrement" value="3" /> 
    <property name="maxStatements" value="0" /> 
</bean> 

私はこれを使用して動作します
