spring - java.lang.NullPointerException：在 org.apache.tiles.access.TilesAccess.getContainer 处为空（TilesAccess.java:124）~[tiles-api-3.0.8.jar:3.0.8]

Question

我正在尝试将 struts 从2.3迁移到2.5.20。作为这项任务的一部分，我必须将瓷砖 2迁移到瓷砖 3

我可以看到我的 tomcat 正在启动并且我可以访问我的端点（其余端点）

我添加了以下插件 struts2-tiles-plugin-2.5.20.jar

还为 Tiles 3 添加了以下罐子：

tiles-api-3.0.8.jar
tiles-autotag-core-runtime-1.2.jar
tiles-compat-3.0.8.jar
tiles-core-3.0.8.jar
tiles-el-3.0.8.jar
tiles-extras-3.0.8.jar
tiles-freemarker-3.0.8.jar
tiles-jsp-3.0.8.jar
tiles-mvel-3.0.8.jar
tiles-ognl-3.0.8.jar
tiles-request-api-1.0.7.jar
tiles-request-jsp-1.0.7.jar
tiles-request-mustache-1.0.7.jar
tiles-request-servlet-1.0.7.jar
tiles-request-servlet-wildcard-1.0.7.jar
tiles-servlet-3.0.8.jar
tiles-template-3.0.8.jar
tiles-velocity-3.0.8.jar

将 XML 中的 DTD 更改为：

<!DOCTYPE tiles-definitions PUBLIC 
        "-//Apache Software Foundation//DTD Tiles Configuration 3.0//EN" 
        "http://tiles.apache.org/dtds/tiles-config_3_0.dtd"> 

我收到以下异常：

注意：我使用apache-tomcat-7.0.88进行部署。

尝试添加以下罐子，但没有成功：

el-api-6.0.20.jar
jasper-el-6.0.20.jar 
javax.servlet-api-3.0.1.jar
javax.servlet.jsp-api-2.3.1.jar
jstl-1.2.jar
