java - Spring Boot中的多个index.html

Question

我有一个简单的 Spring Boot 应用程序，在我的 web 应用程序中有两个 html。

在我的 Controller 中，我编写了如下映射:

@Controller
public class HtmlController {

@RequestMapping(value = "/", method = RequestMethod.GET)
public String index() {
    return "index";
}

@RequestMapping(value = "/anotherIndex", method = RequestMethod.GET)
public String anotherIndex() {
    return "anotherIndex";
}
}

我还有属性:

spring.mvc.view.prefix=/
spring.mvc.view.suffix=.html

当我传入浏览器 localhost:8080/- 我得到我的index.html页面但是当我通过 localhost:8080/anotherIndex 时，我遇到了异常:

javax.servlet.ServletException: Circular view path [/anotherIndex.html]: would dispatch back to the current handler URL [/anotherIndex.html] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

我的代码有什么问题吗？

Answer 1

主要问题是您没有使用为 Spring Boot 中的 Web 应用程序定义的文件夹结构。

你应该有

src
   main
       resources
                templates
                         index.html
                         anotherIndex.html
                         anotherFolder
                             index.html
                         ...

然后从你的 Controller 使用(你说得对)

@RequestMapping(value = "/", method = RequestMethod.GET)
public String index() {
    return "index";
}

@RequestMapping(value = "/anotherIndex", method = RequestMethod.GET)
public String anotherIndex() {
    return "anotherIndex";
}
