java组织。springframework。jdbc。CannotGetJdbcConnectionException:无法获取JDBC连接；

Question

我的错误如下：

意外的数据访问错误：

org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Co
nnection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot
 create JDBC driver of class 'com.sybase.jdbc3.jdbc.SybDriver' for connect URL '
${jdbc.url}'

${jdbc.url}定义如下：

jdbc.url=jdbc:sybase:Tds:mtc-lpsybdb202:6306/df_xur
jdbc.user=AYB_VV_XURVAPS
jdbc.password=wsefsfsfdfffsdfsd

我的数据源。xml有以下代码

  <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jee="http://www.springframework.org/schema/jee"

        <property name="username" value="${jdbc.user}" />
        <property name="password" value="${jdbc.password}" />

        </property>
        <property name="maxIdle">
