使用Jersey測試框架進行呼叫后獲取異常

Question

我正在使用jersey 2.x框架測試其余部分。 當我接到電話時，一切正常。 我正在嘗試測試POST調用，但在執行該調用時遇到異常：

例外是：

我的Resource類如下所示：

@Path("/2/{subversion: [0-3]}/categories")
public class CategoryResource extends AbstractAuthenticationResource {
Logger log = Logger.getLogger(CategoryResource.class);

//For now this property is deprecated. May be used in future.
private static String defaultCardinality = "10";

/**
 *
 * @param proxyCategory
 * @return Response Json Category response
 * @throws Exception
 */
@POST
@Consumes("application/json")
@Produces("application/json")
public Response createCategory(
        final Category proxyCategory) throws Exception {
    log.debug("Inside createCategory()");
}
}

我正在嘗試撥打此電話：

@Test
public void testPost() throws Exception {
    Category category = new Category("TestCategoryId","TestCategoryName");
    Response post = target("/2/0/categories").request().post(Entity.json(category));
    String s = post.readEntity(String.class);
}

我嘗試傳遞的Category類看起來像這樣：

@XmlRootElement(name = "Category")
public class Category implements Serializable {
private static final long serialVersionUID = -8571194852191648098L;

protected String id;
protected String name;

public Category() {
}

public Category(String id, String name) {
    this.id = id;
    this.name = name;
}

public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

}

我在撥打電話時收到上述異常。 我正在使用所有最新版本的球衣和球衣測試。

Answer 1

jersey-media-json-jackson將它們插入，但是使用了不同的版本。 除非您特別需要版本2.7.0，否則請擺脫它們，而只需使用jersey-media-json-jackson引入的版本。

Answer 2

我遇到了同樣的問題，必須刪除與com.fasterxml.jackson相關的依賴項，並使jackson保留在球衣依賴項上。 參見附件我的pom.xml文件。 解決的辦法是注釋Jackson的com.fasterxml依賴項。
