Java Spring MVC应用程序只接受带有尾随斜杠的POST请求

Question

我有一个spring MVC应用程序，具有以下细节

1. WAR文件名为forms.war。web.xml中的url模式是“/”
2. 控制器操作的@requestmapping是“/”
3. RequestMethod.get操作在单击localhost:8080/forms时正常工作
4. RequestMethod.post操作未触发，如果post数据命中localhost:8080/forms
5. POST请求提供302重定向
6. 单击localhost:8080/forms/时，POST请求正常工作

public class HttpPostExample {
    public static void main(String[] args) {
        HttpClient httpClient = HttpClientBuilder.create().build();
        try {

            HttpPost request = new HttpPost("http://localhost:8080/forms");
            StringEntity params =new StringEntity("{\"form_url\":\"admin\",\"website\":\"US_WEBSITE\",\"email\":\"[e-mail]\",\"cis_name\":\"testscrip1\"} ");
            request.addHeader("content-type", "application/x-www-form-urlencoded");
            request.setEntity(params);
            HttpResponse response = httpClient.execute(request);

            System.out.println("Printing the response code " + response.getStatusLine().getStatusCode());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

将url更改为/forms/适用于POST请求，但不适用/forms

Answer 1

将@requestmapping更改为无映射（所以根本不要放值，甚至不要放值“/”)或将“/*”更改为无映射。
