java - Rest Controller 上的 Spring Boot Thymeleaf ViewResolver

Question

问候。

我有一个 Spring Boot 应用程序(1.4.1 版)。 之前设置了来自

的 Thymeleaf

<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 thymeleaf 模板中不严格的 html。 我仅将 Thymeleaf 模板用于电子邮件模板。该应用代表 REST API，所有 Controller 都返回 json 数据。

然而，在我为电子邮件设置 Thymeleaf 后，一些请求正在为它们寻找 Thymeleaf 模板并返回 code 500。

Thymeleaf 配置(yml，这是 thymeleaf 的所有配置，没有其他 JAVA 配置，Spring Boot 处理一切):

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

示例 Controller 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:

对不起大家，那是我的错误。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 Controller 未被注释为 @RestController。固定。
