获取java.lang.ClassNotFoundException：org.apache

Question

我正在执行spring的简单Dependency Injection程序并获取此异常。我已经包含了common-logging1.1.1.jar和spring.jar文件。你能帮忙吗？

Answer 1

如果您正在使用maven来管理依赖项，请在pom.xml中添加以下行：<dependency>&nbsp; &nbsp; &nbsp; &nbsp; <groupId>commons-logging</groupId>&nbsp; &nbsp; &nbsp; &nbsp; <artifactId>commons-logging</artifactId>&nbsp; &nbsp; &nbsp; &nbsp; <version>1.1.1</version></dependency>

Answer 2

commons-logging-1.1.1.jar或jcl-over-slf4j-1.7.6.jar al如果使用的是maven，请使用以下代码。<dependency>&nbsp; &nbsp; <groupId>org.slf4j</groupId>&nbsp; &nbsp; <artifactId>jcl-over-slf4j</artifactId>&nbsp; &nbsp; <version>${slf4j.version}</version></dependency>
