经过一天时间的定位发现是poi版本的问题
原先版本：
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.14</version>
</dependency>
如果只用word的写入只用以下引入就可以，上面的是excel的读写引入的poi。
<dependency>
<groupId>com.deepoove</groupId>
<artifactId>poi-tl</artifactId>
<version>1.7.3</version>
</dependency>
最后经过不通项目测试得出版本是：
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>4.1.0</version>
</dependency>
写入输出正常
在做数据写入word模板中的时候一直报这个错误：经过一天时间的定位发现是poi版本的问题原先版本： <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>3.14</version> <...

该项目是
java
.util.stream及其各种支持接口的替代API，该接口允许引发已检查的异常。
用法示例：
Stream<String> names = Stream.of("

ThrowingStream<String> s = ThrowingStream.of(names,

常会遇到报找不到类的问题，有时是没有引入相关类，但很多时候明明是有的，现把原因简单总结如下：
1、
java
.
lang
.ClassNotFoundException: com.alibaba.nacos.client.logging.NacosLogging
调试spring cloud alibaba总报这个错，查到对应包nacos-client-2.0.3有此类，双击无法打开，果断判断是包下载问题，去仓库删除下载包，maven重新下载，搞定！
2、还有一种常见的报错原因是引入了不同版本的包，两个包都
