嗨,我正在尝试按照Jersey 2.0 的入门指南.
我按原样执行了步骤1.1和1.2.没问题.
对于步骤1.3,我有一个问题,因为maven找不到javax-annotation 1.2但是我按照另一个Stackoverflow用户的建议解决了它,并在我的pom中添加了一个存储库.
所以mvn clean test通过没有问题,但是当我试图跑,mvn clean exec:java我回来

pom.xml是由以下命令创建的:
mvn archetype:generate -DarchetypeArtifactId=jersey-quickstart-grizzly2 \
-DarchetypeGroupId=org.glassfish.jersey.archetypes -DinteractiveMode=false \
-DgroupId=com.example -DartifactId=simple-service -Dpackage=com.example \
-DarchetypeVersion=2.0
我唯一补充的内容如下:
<repositories>
<repository>
<id>java.net.repo</id>
<url>https://maven.java.net/content/groups/promoted/</url>

如果它是感兴趣的,这是输出 mvn -version

Java version: 1.7.0_21, vendor: Oracle Corporation …如何在Jersey 2.0下找出任意URI映射到的资源？在Jersey 1.x下,我使用ResourceContext.matchResource(URI).
我正在尝试做什么:我正在尝试处理通过URI引用另一个资源的传入请求.例如,这是一个将用户链接到部门的操作.
POST /departments/5
{
"user": "http://example.com/users/10"
}
POST/departments/5解决:
class DepartmentResource
{
@POST
void linkUser() { ... }
}
为了兑现这个请求,我需要将URI解析回UserResource并从那里解析为其数据库ID.添加@Context UriInfo到linkUser()不会帮助,因为这UriInfo相当于部门,而不是用户的URI.
更新:我在https://github.com/eclipse-ee4j/jersey/issues/2444上提交了一份错误报告
UPDATE2:发布了一个后续问题:Jersey2:从资源导航到实例
有没有人成功使用JBoss 7.x部署Jersey 2.x？我尝试使用JBoss 7.1.1部署Jersey 2.5,但遇到了如下错误:
"java.lang.NoSuchMethodError: javax.ws.rs.core.Application.getProperties()Ljava/util/Map;"
我相信这个问题是因为JBoss捆绑了RestEasy,这是一个JAX-RS 1.0实现,而Jersey是一个JAX-RS 2.0实现.所以我采取了以下步骤来禁用RestEasy:
1)在我的web.xml中添加了以下内容:
<context-param>
<param-name>resteasy.scan</param-name>
<param-value>false</param-value>
</context-param>
<context-param>
<param-name>resteasy.scan.providers</param-name>
<param-value>false</param-value>
</context-param>
<context-param>
<param-name>resteasy.scan.resources</param-name>
<param-value>false</param-value>
</context-param>
2)在这里讨论之后,我修改了JBoss的standalone.xml,module.xml和domain.xml以删除对JAXRS1.1/RestEasy的所有引用.
3)这导致了另一个错误:"java.lang.NoClassDefFoundError:org/objectweb/asm/ClassVisitor",我通过将以下内容添加到我的pom.xml来解决:
<dependency>
<groupId>asm</groupId>
<artifactId>asm</artifactId>
<version>3.3.1</version>
</dependency>
所以最后我的应用程序部署没有错误,但现在我似乎无法访问我的任何泽西资源.但Jetty 8工作正常.我也能够运行Jersey 1.x,而不必采取步骤#2和#3,但如果可能的话,我更愿意使用Jersey 2.x.
另外我还尝试创建一个jboss-deployment-structure.xml文件,但后来我仍然遇到之前的错误,如"java.lang.NoSuchMethodError:javax.ws.rs.core.Application.getProperties()Ljava/util /地图;"
<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
<deployment>
<exclusions>

</jboss-deployment-structure>
Jboss和Jersey 2.x有没有运气好吗？任何帮助,将不胜感激.
我在将泽西岛从1.x迁移到2.x时遇到了一些问题.我的应用程序使用Jersey提供REST Web服务,通过Jackson和Spring 4以JSON方式提供数据来处理依赖注入.
在Jersey 1.xi用于编写JsonDeserializer作为Spring管理的组件,所以我可以在反序列化期间访问我的服务以从persistance层加载我的域对象,但是在2.x中我遇到了在注入服务时出现问题的问题反序列化器工作.我所采用的方法受到了这篇博文的启发:http://www.runningasroot.com/blog/2012/05/02/autowiring-jackson-deserializers-in-spring/

Jersey版本是2.7,Spring 4.0.2.RELEASE.
这是我的web.xml:

Map<String,String> parameters = new HashMap<String,String>();
for (Map.Entry<String,List<String>> e : queryParameters.entrySet()) {

public class MyApplication extends ResourceConfig {

packages("com.keylesson.service");
// Register my custom provider - not needed if it's in my.package.
register(TestFilter.class);
register(TestFilter2.class);*/
}
}
取消注释后的上面的代码能够执行两个过滤器类,但顺序是TestFilter2,然后是TestFilter.这个Resourceconfig方法我不太喜欢,我想为Jersey2.3使用旧式web.xml.过滤器的球衣1.x init-params在jersey2.3中不起作用.任何人都可以帮助我使用jersey2.3的示例web.xml来保证过滤器的执行吗？还有序列testfilter然后testfilter2？
每当我的REST客户端代码使用下面的代码调用REST服务时,我就会遇到异常: 代码:
public void putWatcher(Watcher watcher)
{
System.out.println("In REST Client putWatcher.***********");
target = target.path(RESOURCE_WATCHERS).path(watcher.getWatcheruri());
System.out.println(target.getUri());
Invocation.Builder builder = target.request();
builder.put(Entity.json(watcher));
// Response response = target.request().put(Entity.json(watcher));
System.out.println("Returned from REST Call");
}

我的REST服务部署在Tomcat 8服务器上,客户端代码部署在JBoss 7.2上. 客户端应用程序是SIP-Servlets应用程序,它也捆绑了REST客户端. …
这是我的web.xml:

@Path("/main")
public class MainResource {

public Planet getPlanet() {
final Planet planet = new Planet();
planet.id = 1;
planet.name = "Earth";
planet.radius = 1.0;
return planet;
