问题描述

在SpringBoot项目中使用Thymeleaf作为模板引擎时，出现了以下错误：

[THYMELEAF][http-nio-8080-exec-1] Exception processing template "xxx": Error resolving template [xxx], template might not exist or might not be accessible by any of the configured Template Resolvers

问题分析-解决方案

首先，检查是否引入了thymeleaf依赖。
若没有，则需在在pom.xml加入：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId> 
</dependency>

若引入后仍然报错，说明返回的内容不是Json字符串。
在@RequestMapping的上面加上@ResponseBody注解即可。
