我写了一个应该在Glassfish 4上运行的maven应用程序.

标准ApplicationConfig如下所示:

@javax.ws.rs.ApplicationPath("resources")
public class ApplicationConfig extends Application {

    @Override
    public Set<Class<?>> getClasses() {
        Set<Class<?>> resources = new java.util.HashSet<Class<?>>();
        // following code can be used to customize Jersey 2.0 JSON provider:

        try {
           Class jsonProvider = Class.forName("org.glassfish.jersey.jackson.JacksonFeature");

        } catch (ClassNotFoundException ex) {
            java.util.logging.Logger.getLogger(getClass().getName()).log(java.util.logging.Level.SEVERE, null, ex);
        }
        addRestResourceClasses(resources);
        return resources;
    }

现在的问题是,我生成Json的资源应该使用jackson 2.3注释.但我的glassfish使用了一些codehaus....包提供json.codehaus是杰克逊的旧版本.我想使用来自fastxml的新文件,它提供@JsonIdentityInfo注释.

我以为我可以写下来解决我的问题:

@javax.ws.rs.ApplicationPath("resources")
public class ApplicationConfig extends Application {

    @Override
    public Set<Class<?>> getClasses() {
        Set<Class<?>> resources = new java.util.HashSet<Class<?>>();

        resources.add(JacksonFeatures.class);  //from the com.fasterxml.jackson.jaxrs.annotation Package
        resources.add(JacksonJaxbJsonProvider.class);
        resources.add(JacksonJsonProvider.class);

        addRestResourceClasses(resources);
        return …

我需要提供一个java REST客户端,它应该包含一个包中所有必需的jar.我选择RestEasy作为REST框架,因为服务器应用程序是在JBoss上完成的.

到目前为止,我发现的几乎所有示例都使用应用程序容器环境,其中提供了这些lib,因此在编译期间只需要Java EE API或使用Maven构建,因此依赖项会自动解决,这可能是一个好主意,当前的标准方法,但由于项目相关的原因,我需要在lib文件夹中的jar,并能够在构建期间包含一个可执行jar.

所以我的问题是,哪个罐子有必要建立一个可以做类似的简单客户端:

ResteasyClient client = new ResteasyClientBuilder().build();
ResteasyWebTarget target = client.target(myURL).queryParam("param",
                "value");
Builder builder = target.request(MediaType.APPLICATION_JSON).header("user", "abc");
Invocation invocation = builder.buildGet();
MyResponseObject response = invocation.invoke(MyResponseObject .class);

我在Java EE 7应用程序中实现JAX-WS服务时遇到以下异常.

异常消息似乎非常特定于GlassFish Server(我正在使用4.1).

测试场景:

CDI托管bean:

@Named
@ViewScoped    
public class TestManagedBean implements Serializable
{
    private String test;
    private static final long serialVersionUID=1L;

    public TestManagedBean() {}

    @PostConstruct
    private void init() {
        TestBean_Service testBean_Service=new TestBean_Service(); …

我正在使用com.google.gson.GsonAPI将JSON字符串转换为Java对象:

Gson gson = new Gson();
User u = gson.fromJson(jsonString, User.class);

我想知道javax.json api中是否有等效的API 来做等效的.谢谢!

我正在构建一个测试套件，以便在Arq​​uillian上执行它们。我遵循了Arquillian的入门指南 ，正在使用此gradle测试我的测试：
