SpringBoot整合poi实现Word文件的导出

SpringBoot整合poi实现Word文件的导出

1、引入Maven依赖

        <dependency>
			<groupId>org.apache.poi</groupId>
			<artifactId>poi</artifactId>
			<version>3.16</version>
		</dependency>
		<dependency>
			<groupId>org.apache.poi</groupId>
			<artifactId>poi-ooxml</artifactId>
			<version>3.16</version>
		</dependency>
		<dependency>
			<groupId>org.apache.poi</groupId>
			<artifactId>poi-scratchpad</artifactId>
			<version>3.16</version>
		</dependency>

2、封装WordUtils工具类
