Question

我正在使用 Spring 和 Spring Security 开发 Java 8 Web应用程序。我的IDE是 Intellij IDEA Ultimate ，该应用程序已与Intellij一起部署到 Tomcat 8.5 。构建过程使用两个Maven配置文件。如果我尝试通过Intellij Tomcat运行配置启动应用程序，有时（并非每次都很奇怪）（对于每次target\webapp\WEB-INF\lib\），我都会得到 FileNotFoundExceptions 。

ErrorStack示例：

在您的pom.xml中添加jar依赖项-

Dependencies : add dependency in your pom.xml

<dependency>
 <groupId>org.springframework.data</groupId>
 <artifactId>spring-data-jpa</artifactId>
 <version>1.11.1.RELEASE</version>
</dependency>

Build Configuration :
