You have included a dependency on the SLF4J API, which is what you use in your application for logging, but you must also include an implementation that does the real logging work.
您已经包含了对 SLF4J API 的依赖，这是您在应用程序中用于日志记录的内容，但您还必须包含一个执行实际日志记录工作的实现。
For example to log through Log4J you would add this dependency:
例如，要通过 Log4J 登录，您将添加此依赖项：
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.5.2</version>
</dependency>
The recommended implementation would be logback-classic, which is the successor of Log4j, made by the same guys that made SLF4J and Log4J:
推荐的实现是 logback-classic，它是 Log4j 的继承者，由制作 SLF4J 和 Log4J 的同一个人制作：
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>0.9.24</version>
</dependency>
Note: The versions may be incorrect.
注意：版本可能不正确。

You have included the dependency for sflj's api, but not the dependency for the implementation of the api, that is a separate jar, you could try slf4j-simple-1.6.1.jar.
你已经包含了sflj的api的依赖，但没有包含实现api的依赖，那是一个单独的jar，你可以试试slf4j-simple-1.6.1.jar。

将所有tiles jars like(tiles-jsp,tiles-servlet,tiles-template,tiles-extras.tiles-core) 添加到你的服务器lib文件夹和你的应用程序构建路径，然后如果你在spring mvc应用程序中使用apache tailes，它就可以工作

Copy all order entries of home folder .iml file into your /src/main/main.iml file. This will solve the problem.
将主文件夹 .iml 文件的所有订单条目复制到您的 /src/main/main.iml 文件中。这将解决问题。
