注意大多數是包依賴缺失

好多教程裡寫的是加入 

      <dependency>
		  <groupId>com.deepoove</groupId>
		  <artifactId>poi-tl</artifactId>
		  <version>1.3.1</version>
	  </dependency>

其實還得加入下面的依賴

<dependency>
          <groupId>org.apache.poi</groupId>
          <artifactId>poi-ooxml-schemas</artifactId>
          <version>3.14-beta1</version>
      </dependency>
      <dependency>
          <groupId>org.apache.poi</groupId>
          <artifactId>poi-ooxml</artifactId>
          <version>3.14-beta1</version>
      </dependency>
      <dependency>
          <groupId>org.apache.poi</groupId>
          <artifactId>poi-ooxml-schemas</artifactId>
          <version>3.14-beta1</version>
      </dependency>
      <dependency>
          <groupId>org.apache.poi</groupId>
          <artifactId>poi</artifactId>
          <version>3.14-beta1</version>
      </dependency>
 

最後能夠成功了

具體怎麼做的程式碼，請自行百度，例子很多。
