将JSON数据传递给REST服务

Question

当我使用POST休息服务传递json数据时会收到类似不支持的mediatype的错误。

Caused By: Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.6.1.v20150916-55dc7c3): org.eclipse.persistence.exceptions.DatabaseException

当我试图在邮递员中使用这些作为标题呼叫休息时 - 内容类型：application / json，响应：请求失败。 接受：application / json，响应：不支持的媒体类型。

这是我的休息方法 - （FACADEREST），

    @Path("count")
    @Produces(MediaType.TEXT_PLAIN)
    public String countREST() {
        return String.valueOf(super.count());
    }

    @Override
    protected EntityManager getEntityManager() {
        return em;
    }

}

我正在使用它来创建休息服务。
