声明返回Respons这种模式，客户端是通过服务发现的机制，基于 consumer 的方式调用，还是直接端项目通过http？ |
直接通过前端项目HTTP的，为了发布RESTful API的。 |

Steps to reproduce this issue
接口定义如下：
`
@path("users")
@consumes({ContentType.APPLICATION_JSON_UTF_8})
@produces({MediaType.APPLICATION_JSON})
public interface UserService {
}
`
以上使用dubbo发布为REST风格的服务（参见上面接口定义），把dubbo版本从3.1.9升级到3.2.0出现了几个问题，问题如下：
1、不能出现相同的URI而HTTP method不同，导致服务不能启动；
比如：GET http://127.0.0.1:8080/users 与 POST http://127.0.0.1:8080/users
GET http://127.0.0.1:8080/users/1 与 DELETE http://127.0.0.1:8080/users/1
3.2.0版本的启动报错内容在最底下。
注：这个问题在dubbo 3.1.9版本中并不会出现
2、在dubbo 3.2.0中一个URI无论用什么HTTP method请求都可以成功；
在接口定义的方法中中使用@get注解，使用GET还是其他HTTP方法都可以正常访问且HTTP响应状态为200
注：这个问题在dubbo 3.1.9版本中使用非注解的HTTP方法请求会得到HTTP status为405（Method Not Allowed）
3、同样是javax.ws.rs.core.Response返回类型，但3.1.9和3.2.0版本在HTTP body中的内容不相同；
在下面的实现中：
public Response getUsers() {
HashMap<String, Object> map = new HashMap<>();
map.put("code", 10000);
map.put("msg", "ok~~~");
return Response.serverError().entity(map).build();
}
使用3.1.9版本的HTTP body为
{
"msg": "ok~~~",
"code": 10000
}
使用3.2.0版本的HTTP body为
{
"allowedMethods": [ ],
"closed": false,
"cookies": { },
-"entity": {
"msg": "ok~~~",
"code": 10000
},
"entityClass": "java.util.HashMap",
"headers": { },
"length": -1,
"links": [ ],
"metadata": { },
"reasonPhrase": "Internal Server Error",
"status": 500,
"statusInfo": "INTERNAL_SERVER_ERROR",
"stringHeaders": { }
}
在dubbo-rpc-rest 3.1.9版本中依赖的是jboss-jaxrs-api_2.0_spec而在dubbo-rpc-rest 3.2.0中依赖的是jboss-jaxrs-api_2.1_spec，在3.1.9中直接返回entity而3.2.0返回Response，造成这种差异的原因不知道是dubbo方面的原因还是jaxrs-api的原因，又或者项目配置的问题呢？
3.2.0版本启动报错：
