错误场景

在使用阿里巴巴的easyexcel，调用后台接口读取指定excel文件进行输出打印时报错

org.thymeleaf.exceptions.TemplateInputException: Error resolving template [excel/readExcel], template might not exist or might not be accessible by any of the configured Template Resolvers
    at org.thymeleaf.engine.TemplateManager.resolveTemplate(TemplateManager.java:869) ~[thymeleaf-3.0.14.RELEASE.jar:3.0.14.RELEASE]
    at org.thymeleaf.engine.TemplateManager.parseAndProcess(TemplateManager.java:607) ~[thymeleaf-3.0.14.RELEASE.jar:3.0.14.RELEASE]

代码如下

pom.xml

<!--读取excel文件-->
<dependency>
     <groupId>com.alibaba</groupId>
     <artifactId>easyexcel</artifactId>
     <version>2.2.6</version>
 </dependency>

Controller

//读取指定的Excel
@RequestMapping(value = "/readExcel")
 public List<Teacher> readExcel() {
   
     String fileName = "C:\\Users\\211145187\\Desktop\\fsdownload\\details (1).xls";
     TeacherListener studentListener = new TeacherListener();
     EasyExcel.read(fileName, Teacher.class, studentListener).sheet().doRead();
     return studentListener.getTeacherList();
 }

读取的excel文件如下

解决方案2种

第一种方案：@Controller => @RestController

第二种方案：方法添加注解 @ResponseBody
