Question

我不确定这是一个码头问题还是shiro的问题，但我正在尝试使用Jetty-Maven插件进行开发，我想要的一个关键功能是Jetty在文件更改时的热重新部署。但是，当jetty尝试重新加载应用程序时，Shiro会抛出以下异常，我不确定如何解决这个问题。

我的web.xml如下所示：

<?xml version="1.0" ?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
    version="2.4">  

<!-- SHIRO CONFIGURATION ============================================== -->

<listener>
  <listener-class>org.apache.shiro.web.env.EnvironmentLoaderListener</listener-class>
</listener>

<filter>
  <filter-name>ShiroFilter</filter-name>
  <filter-class>org.apache.shiro.web.servlet.ShiroFilter</filter-class>
</filter>

<filter-mapping>
  <filter-name>ShiroFilter</filter-name>
  <url-pattern>/*</url-pattern>
  <dispatcher>REQUEST</dispatcher>
  <dispatcher>FORWARD</dispatcher>
  <dispatcher>INCLUDE</dispatcher>
  <dispatcher>ERROR</dispatcher>
</filter-mapping>

<!-- DATA SOURCE ====================================================== -->

<resource-ref>
  <description>Account Data Source</description>
  <res-ref-name>jdbc/AccountDB</res-ref-name>
  <res-type>javax.sql.DataSource</res-type>
  <res-auth>Container</res-auth>
</resource-ref>

</web-app>

最后，这是我的maven pom文件的相关部分：

<build>
  <plugins>
    <plugin>
      <groupId>org.eclipse.jetty</groupId>
      <artifactId>jetty-maven-plugin</artifactId>
      <version>9.0.0.RC2</version>
      <configuration>
        <jettyXml>src/jetty/jetty.xml</jettyXml>
        <scanIntervalSeconds>1</scanIntervalSeconds>
        <webApp>
          <contextPath>/</contextPath>
          <overrideDescriptor>src/jetty/override-web.xml</overrideDescriptor>
        </webApp>
      </configuration>
      <dependencies>
        <dependency>
          <groupId>mysql</groupId>
          <artifactId>mysql-connector-java</artifactId>
          <version>5.1.24</version>
        </dependency>
      </dependencies>
    </plugin>
  </plugins>

编辑：另一条相关的信息。我在eclipse中编辑文件，我正在使用M2E Maven Integeration for Eclipse插件。它可能与eclipse和/或这个插件重新编译文件的方式有关。
