我正在关注 Struts2 中的 Tile 教程，但遇到了以下错误：

您添加错误消息说丢失的库；Slf4J。

看起来您正在尝试手动进行依赖管理——IMO 这是一个非常糟糕的主意。它使升级困难、部署困难、难以理解编译、测试和部署要求之间的差异等等。

例如，为什么要部署源 jar 或 junit？

如果您收到以下错误：java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory at org.apache.tiles.web.startup.AbstractTilesListener。

添加此依赖项

<dependency>
            <groupId>org.apache.tiles</groupId>
            <artifactId>tiles-core</artifactId>
            <version>2.2.2</version>
        </dependency>

或添加这个罐子：slf4j-api-1.5.8.jar jcl-over-slf4j-1.5.8.jar
