Question

我第一次尝试了一个spring（3.1.0）项目，但它给了我运行时错误。我添加了log4j但仍然发生错误。org.springframework.beans.factory.xml.XmlBeanFactory也被弃用了。请帮帮我

这就是我得到的

Answer 1

你需要在类路径中记录apache commons。 Log4j不是commons-logging。

Answer 2

从下载公共记录jar http://commons.apache.org/logging/download_logging.cgi

Answer 3

您可以检查哪个类位于哪个Opensource（OSS）库here。

如果您使用的是Maven，可以尝试添加以下依赖项：

<dependency>
   <groupId>commons-logging</groupId>
   <artifactId>commons-logging</artifactId>
   <version>1.1.1</version>
   <classifier>api</classifier>
</dependency>
