Question

当我重新启动tomcat时，它会抛出异常：

Apr 28, 2017 2:33:58 PM org.apache.catalina.session.StandardManager doLoad

在我的项目中，我使用spring security 4.2.2

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-web</artifactId>
    <version>${org.springframework-version}</version>
</dependency>

Tomcat版本：

Server version: Apache Tomcat/7.0.64 (Ubuntu)
Server built:   Jun 29 2016 12:48:32 UTC
Server number:  7.0.64.0
OS Name:        Linux
OS Version:     3.13.0-96-generic
Architecture:   amd64
JVM Version:    1.7.0_111-b01
JVM Vendor:     Oracle Corporation

我的webapp的lib文件夹jar中有一个spring-security-web-4.2.2.RELEASE.jar文件，当tomcat启动时，它运行正常。

如何正确地进行tomcat重装会话，或者如何解决？

谢谢！

由于`ClassNotFoundException：org.springframework.security.web.csrf.DefaultCsrfToken`，Tomcat无法重新加载会话，如何修复？
