struts2.2.1 org/apache/struts2/convention/PackageBasedActionConfigBuilder

环境tomcat6，struts2.2.1，使用convention plugin 2.2.1，启动tomcat报错：

org/apache/struts2/convention/PackageBasedActionConfigBuilder.java 592

org/apache/struts2/convention/PackageBasedActionConfigBuilder.java

 

搜了下网上的原因：https://issues.apache.org/jira/browse/WW-3486

 

后来把struts.xml里的：

<constant name="struts.devMode" value="false" />
    <constant name="struts.convention.classes.reload" value="false" />

设置成false，成功解决问题。

 

struts2.2.1官方文档里有这一段：

Automatic configuration reloading

The Convention plugin can automatically reload configuration changes, made in classes the contain actions, without restarting the container. This is a similar behavior to the automatic xml configuration reloading. To enable this feature, add this to your struts.xml file:

<constant name="struts.devMode"
 value="true"
/>

<constant name="struts.convention.classes.reload"
 value="true"
 />
 

This feature is experimental and has not been tested on all container, and it is strongly advised not to use it in production environments.

 

明确写道这两个选项可能会导致问题！
