我使用Backbone.js,Bootstrap,NetBeans IDE 8.0,Java EE 7,JDK 8,WildFly服务器8.1.0,JBoss RESTEasy(resteasy-jaxrs-3.0.8),JBoss 2.2.22,JBoss EJB 3制作Web应用程序.
我(相对)是Web开发的新手,因此我才开始掌握很多基本概念和技术.我正在尝试将用户和角色的权限系统构建到Web应用程序中,但我似乎无法使@RolesAllowed注释在我的RESTful Web服务中工作.我已经在这个问题上工作了几天.
我有一个名为UserResource.java的RESTful资源(Java Enterprise/Session Bean？),在这里我有一个方法create来为应用程序创建一个新用户:
import java.net.URI;
import java.security.Principal;
import java.util.List;
import javax.annotation.security.PermitAll;
import javax.annotation.security.RolesAllowed;
import javax.ejb.EJB;
import javax.ejb.Stateless;
import javax.ws.rs.*;
import javax.ws.rs.core.*;
import org.jboss.ejb3.annotation.SecurityDomain;
@Stateless
@SecurityDomain("other")
@Path("/user")
public class UserResource {
@EJB(name = "UserServiceImp")
UserService userService;
@Context
private UriInfo uriInfo;
@RolesAllowed({"admin"})
@Path("create")
@POST
public Response create(CreateRequest request) {
try {
System.out.println("Start of create method");
User user = userService.createUser(request);
return getCreateResponse(user);
}
catch (Exception …我尝试使用CorsFilterResteasy 3.0.9中提供的新功能.我在本页底部找到了一个示例:
使用JAX-RS/RESTEasy实现CORS的Ajax请求
如果我在方法getSingletons()(Application子类)中定义此过滤器,那么我的资源不再被扫描.这意味着将找不到资源并发生以下错误:
javax.ws.rs.NotFoundException: Could not find resource for full path Error Occures
在下一页我找到了一个描述: javax.ws.rs.NotFoundException:找不到完整路径的资源错误Occures
但基本上,此部署选项的作用是扫描应用程序的@ Path,@ Extider等注释.原因是JAX-RS将首先分别在重写的getClasses()和getSingletons()中查找类和对象.如果然后返回空集,则告诉JAX-RS进行扫描(根据规范).
所以如果我覆盖这个getSingletons()方法,JAX-RS不会进行扫描？有没有其他方法来配置它CorsFilter并启用资源扫描？
根据文件,
"客户端是管理客户端通信基础设施的重量级对象.初始化以及客户端实例的处理可能是一项相当昂贵的操作.因此建议在应用程序中仅构建少量客户端实例."
好吧,我正在尝试将Client本身和WebTarget实例缓存在一个静态变量中,someMethod()在多线程环境中调用:
private static Client client = ClientBuilder.newClient();
private static WebTarget webTarget = client.target("someBaseUrl");
...
public static String someMethod(String arg1, String arg2)
{
WebTarget target = entrTarget.queryParam("arg1", arg1).queryParam("arg2", arg2);
Response response = target.request().get();
final String result = response.readEntity(String.class);
response.close();
return result;
}
但有时(并非总是)我得到一个例外:
BasicClientConnManager的使用无效:仍然分配了连接.确保在分配另一个连接之前释放连接.
如何正确地重用/缓存Client/WebTarget？是否可以使用JAX RS Client API？或者我必须使用一些特定于框架的功能(resteasy/jersey)你能提供一些示例或文档吗？
我使用keycloak保证我的休息API,我跟着这个教程以编程方式添加用户,但我得到这个错误信息:

据我了解,这是因为与Android的Apache HttpClient实现不兼容.在线搜索,我发现了各种解决方案,包括org.apache.httpconnections:httpclient在gradle依赖项中,并compile.exclude module: httpclient在几个变体中添加(以解决由此产生的冲突).我已经尝试了所有这些并且总是遇到gradle或NoSuchMethodError上面提到的错误.
是否可以RESTEasyClient在Android 上成功使用？我需要采取哪些步骤才能启用此功能？
我在JBoss AS 6中通过RestEasy使用JAX-RS.当我的JAX-RS资源返回一组项目时(例如通过List),RESTEasy总是使用该名称collection作为根元素.
例如
<collection>
<item>
<description>computer</description>
<price>2500</price>
</item>
<item>
<description>tv</description>
<price>1500</price>
</item>
</collection>
此XML由以下内容生成:
@Produces("application/xml")
@Path("xml")
@RequestScoped
public class MyResource {
@GET
@Path("myitems")
public List<Item> getMyItems() {
return ...
}
}
可以看出,RESTEasy创建的根标记始终是<collection>.
另一方面,泽西岛总是创建一个名称,该名称是列表中包含的元素的复数形式:
<items>
<item>
<description>computer</description>
<price>2500</price>
</item>
<item>
<description>tv</description>
<price>1500</price>
</item>
</items>
我知道可以创建一个包装器类型并返回而不是List,但这是一个相当精细的解决方法,并使代码更复杂.
是否可以轻松指定集合的根标签名称？
RESTEasy(一个JAX-RS实现)有一个很好的客户端框架,例如:
RegisterBuiltin.register(ResteasyProviderFactory.getInstance());
SimpleClient client = ProxyFactory.create(SimpleClient.class, "http://localhost:8081");
client.putBasic("hello world");
你如何设置HTTP标头？
澄清:
jkeeler提出的解决方案是一个很好的方法,但我想在ProxyFactory级别设置HTTP标头,我不想将标头传递给客户端对象.有任何想法吗？
我正在尝试编写简单的RESTEasy客户端.下面给出的是示例代码:
Client client = ClientBuilder.newBuilder().build();
WebTarget target = client.target("http://localhost:8080/context/path");
Response response = target.request().post(Entity.entity(object, "application/json"));
//Read output in string format
String value = response.readEntity(String.class);
我在线上得到例外:
Client client = ClientBuilder.newBuilder().build();
我在控制台中看到以下错误:

我在pom.xml中添加了resteasy客户端依赖性:
<dependency>
<groupId>org.jboss.resteasy</groupId>
<artifactId>resteasy-client</artifactId>
<version>3.0.8.Final</version>
</dependency>
我的代码部署在JBOSS EAP 6.1上.JDK版本是1.7.
更新:我也尝试在我的pom中添加resteasy jax-rs dependancy.我还通过在web.xml中添加以下行来验证是否启用了ResteasyProviderFactory:

当客户端中止与服务器的呼叫时,RestEasy的SynchronousDispatcher可以(显然)不发送响应返回给其造成了一堆错误的在客户端[SEVERE]和[ERROR]水平在我的服务器日志显示出来.
但是,我不认为这些是实际错误,所以我不想看到它们.特别是一旦服务将被公开使用,这必然会发生.
