Question

我正在尝试从2.4迁移到2.5。我在过滤器代码中遇到问题。以下是我的过滤器代码

public class Filters implements HttpFilters {

    private final SecurityFilter securityFilter;

    @Inject
    public Filters(SecurityFilter securityFilter) {
        this.securityFilter = securityFilter;
    }

    @Override
    public EssentialFilter[] filters() {
        return new EssentialFilter[] {securityFilter.asJava()};
    }
}

根据文件https://www.playframework.com/documentation/2.5.x/JavaHttpFilters

asJava（）方法可用，并且在带有2.5 jar的eclipse中完美编译。但是当我通过激活器ui或者激活器dist 时，上面的代码失败了。

我已经用下面的内容更新了plugins.sbt addSbtPlugin（＆＃34; com.typesafe.play＆＃34;％＆＃34; sbt-plugin＆＃34;％＆＃34; 2.5.1＆＃34;）

但它仍然失败。还有什么应该改变？或者是否有其他配置需要更改？

当我将我的应用程序从2.4迁移到2.5时，我遇到了同样的问题，我解决了这个问题：

我将过滤器代码更改为：

import play.filters.cors.CORSFilter;
import play.http.DefaultHttpFilters;

import javax.inject.Inject;

public class Filters extends DefaultHttpFilters {

@Inject public Filters(CORSFilter corsFilter) {
    super(corsFilter);
}

然后按照文档中的步骤进行操作：Enabling the CORS filter

添加build.sbt

libraryDependencies + = 过滤器

在application.conf中配置cors：

filters{
# CORS filter configuration
cors {

  # The path prefixes to filter.
  pathPrefixes = ["/json/rest/api"]

  # The allowed origins. If null, all origins are allowed.
  allowedOrigins = null

  # The allowed HTTP methods. If null, all methods are allowed
  allowedHttpMethods = ["POST","GET"]

  # The allowed HTTP headers. If null, all headers are allowed.
  allowedHttpHeaders = null

  # The exposed headers
  exposedHeaders = []

  # Whether to support credentials
  supportsCredentials = true

  # The maximum amount of time the CORS meta data should be cached by the client
  preflightMaxAge = 1 hour
}

随时提出任何问题。
