问候

我有一个Spring Boot应用程序(1.4.1版).
以前从

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
    <groupId>net.sourceforge.nekohtml</groupId>
    <artifactId>nekohtml</artifactId>
    <version>1.9.22</version>
</dependency>

nekohtml-支持百里香模板中不严格的html.
我仅将Thymeleaf模板用于电子邮件模板.该应用程序代表REST API,所有控制器均返回json数据.

但是,在为电子邮件设置Thymeleaf之后,一些请求正在为其寻找Thymeleaf模板并返回代码500.

Thymeleaf配置(yml,这是百里香的所有配置,没有其他JAVA配置,Spring Boot处理所有内容)：

  thymeleaf:
    check-template-location: true
    prefix: classpath:/templates/
    suffix: .html
    mode: LEGACYHTML5
    encoding: UTF-8
    content-type: text/html 
    cache: true

示例控制器和错误：

@RequestMapping(value = "/register", method = RequestMethod.POST)
public JsonResponse AddUser(@RequestBody @Valid User user, WebRequest request) throws SQLException {
    String result = userService.RegisterUser(user);
    if(result.equals("done")) {
        try {
            eventPublisher.publishEvent(new OnRegistrationCompleteEvent(user, request.getLocale()));
        } catch (Exception me) {
            return new JsonResponse("FAIL", "Unknown on event publishing: "+ me.getMessage());
        }
        return new JsonResponse("OK", "");

    } else if(result.equals("duplicate")) {
        return new JsonResponse("FAIL", "duplicate");
    }
    return new JsonResponse("FAIL", "Unknown");
}

错误：

解决方法:

抱歉,这是我的错误.以前,我将应用程序从Spring MVC迁移到Spring Boot,并将其拆分为REST API和前端.
特别是该控制器没有被注释为@RestController.固定.
