My perception is right. This was jar file problem. You did not put right JSF jar file in your classpath.
我的认知是对的。这是 jar 文件问题。您没有在类路径中放置正确的 JSF jar 文件。
<dependency>
<groupId>javax.faces</groupId>
<artifactId>javax.faces-api</artifactId>
<version>2.1</version>
</dependency>
Replace above dependency with following dependency:
用以下依赖替换上面的依赖：
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.faces</artifactId>
<version>2.1.13</version>
</dependency>
