请参阅下面的 spring servlet 文件配置。它曾经可以工作，现在在将依赖项升级到 Spring core 4.0 和 Spring sec oauth 2.0 之后，它就不起作用了。我的意思是，我无法获得令牌。请参阅以下错误消息和问题：
当我尝试使用以下 URL 获取令牌时，它会给出 406 错误：
网址：/oauth2/oauth/token
“错误”：此请求标识的资源只能生成具有根据请求“接受”标头不可接受的特征的响应。
我是否缺少 Spring 4.0 和 Spring security 3.2 或 Spring security oauth 2.0.0 中的任何新配置
以下是详细信息：
这是一个基于 REST 的 API，没有客户端。我在 chrome 浏览器上用 Postman 测试了这个。明确地说，我没有在接受标头中发送任何内容。使用旧版本的 spring oauth2，它确实适用于接受标头中的 application/json。
使用下面提到的依赖版本，我得到了这个响应，它工作正常。但是，一旦我升级到新的依赖版本，它就会失败并给出 406：
{“access_token”：“f9287b1d-243b-453d-9d3e-f5ed67e974f6”，“token_type”：“bearer”，“refresh_token”：“c6a45534-7c20-4dda-b6f1-9a231cb649ed”，“expires_in”：299999，“范围” ：“读写”}
我使用以下依赖项来工作。：
<properties>
<springsec.version>3.1.0.RELEASE</springsec.version>
<spring.version>3.1.0.RELEASE</spring.version>
<jersey-version>1.18.1</jersey-version>
<springoauth2-version>1.0.0.RELEASE</springoauth2-version>
</properties>
New dependencies I changed to when it started to fail:
<properties>
<springsec.version>3.2.5.RELEASE</springsec.version>
<spring.version>4.1.1.RELEASE</spring.version>
<jersey-version>1.18.1</jersey-version>
<springoauth2-version>2.0.3.RELEASE</springoauth2-version>
</properties>
第一个是使用 InMemoryTokenStore 实现的。但是，现在我们要使用 JDBCTokenStore。我读到，Spring oauth2 2.0 具有更好的特性，所以我开始更改依赖项，同时我必须更改代码中的一些包引用，因为它们现在在 2.0 中已更改。

以下是两种实现的 curl 响应：
这是新的实现 Spring 4 和 Spring oauth 2.0.3
curl -v -X POST -d "username=user1&password=user1&client_id=client1&client_secret=client1&grant_type=password" -H "Accept:application/json" [url1]
它失败了：

这是使用 Spring 3 和 Spring oauth 1.0 的旧实现 - 它给出了正确的响应
