替换效果:

1. 引入maven依赖

   <dependencies><!-- springboot --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><version>RELEASE</version></dependency><!-- poi --><dependency><groupId>org.apache.poi</groupId><artifactId>poi</artifactId><version>3.7</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-ooxml</artifactId><version>3.7</version></dependency><dependency><groupId>org.apache.poi</groupId><artifactId>poi-scratchpad</artifactId><version>3.7</version></dependency></dependencies>
