java - Oracle 池数据源 - 无法找到 Spring NamespaceHandler

Question

我想使用 Spring 实现 Oracle Pooling DataSource，如下所述: http://docs.spring.io/spring-data/jdbc/docs/current/reference/html/orcl.datasource.html

但是，我遇到了这个问题:

Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/data/orcl]
Offending resource: class path resource [applicationContext.xml]

据我了解，这个问题是因为Spring无法定位到Oracle JDBC Driver导致的。但是，驱动程序在我的类路径中；所以，我不知道是什么导致了这个问题。

applicationContext.xml

Answer 1

似乎缺少对 spring-data-oracle 的依赖。试试这个:

<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-oracle</artifactId>
  <version>1.2.1.RELEASE</version>
</dependency>
