我在STS中将以下内容作为我的servlet-context.xml,产生错误Build path is Incomplete. Cannot find class file for javax/servlet.ServletContext
。如果我对行<tx:annotation-driven transaction-manager="transactionManager"/>
发表评论,则错误消失。但我显然想要启用Transactional行为,因此我需要保留它。

答案 0 :(得分:1)
添加它可以解决您的问题:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
或者,如果您使用的是servlet 3.1(或3.0.1),则可以使用以下内容:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
