检查一下你的配置哪儿有问题

[爪哇三郎]

SpringObjectFactory

与spring整合出错了

[Gmonday]

引用 2 楼 u012480848 的回复:

SpringObjectFactory

根本没有用到spring

[Defonds]

web.xml 里加入

<listener>
	<listener-class>
		org.springframework.web.context.ContextLoaderListener
	</listener-class>
</listener>

试试

你的项目里是不是有struts2-spring-plugin这个jar包？

根本没有啊 我上传了jar包的截图 在上面

[末日哥]

应该是多引入的jar的原因，删除一些不必要的包，想你antlr.jar就导入了2次
