Spring Boot不允许POST请求静态资源

标签： java spring spring-mvc spring-boot http-post

我有一个使用Angular 2前端的spring boot Web应用程序。当我构建我的应用程序时，我的Angular 2前端都位于我的类路径的/static/目录中，因此spring boot将它作为静态资源提供。

我的应用程序使用SAML 2.0对IdP进行身份验证，当身份验证后IdP返回我的应用程序时，它会发送POST请求以发布SAML响应。

这导致 405 - 方法不允许。

有没有办法允许POST请求通过spring boot启动静态资源？

我甚至尝试添加一个接受POST请求的控制器，只需将请求转发到我的应用程序的根目录到index.html。

我在application.properties中添加了以下属性：

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

并添加了以下控制器：

@Controller
public class IndexController {

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

}

但无济于事。 Spring启动仍在内部解析我对静态服务资源的请求，该资源不允许POST请求。以下是来自spring的相关调试消息：

我最终添加了spring-boot-starter-thymeleaf作为依赖项，然后将index.html移出/static/并进入/templates/。我从application.properties中删除了spring.mvc.view.prefix和spring.mvc.view.suffix属性，因为spring boot thymeleaf将自动在.html中查找/templates/个模板。执行此操作后，我的index.html在春天之前不再作为静态资源提供，我的IndexController（原始问题中显示的相同）正确处理我的POST请求并呈现＆＃34 ;索引＆＃34;视图，正确显示我的index.html。
