使用Jersey Jersey的Spring服务中的NoClassDefFoundError(javax/ws/rs/ProcessingException) [英] NoClassDefFoundError(javax/ws/rs/ProcessingException) in spring service by using Jersey lib
本文介绍了使用Jersey Jersey的Spring服务中的NoClassDefFoundError(javax/ws/rs/ProcessingException)的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我尝试在项目(A)中使用Jersey.
I have tried using Jersey in my project(A).
有一项服务，我新建了一个实例，如下所示:
There has a service and I new a instance as below:
@Service
public class DatabaseServiceImpl implements DatabaseService
{
HttpClient hc = new HttpClient();
}
HttpClient如下:
The HttpClient as below:
public class HttpClient
{
public HttpClient()
{
clientConfig = new ClientConfig().register(new JacksonFeature());
client = ClientBuilder.newClient(clientConfig);
HttpAuthenticationFeature auth = HttpAuthenticationFeature.basic(username, password);
webTarget = client.target(baseURL).register(auth);
etc..
}
}
HttpClient代码在刚刚创建用于测试的另一个项目(B)中运行良好. 但是，当我将此代码添加到项目(A)中时，编译就可以了，但是启动tomcat会引发错误:
The HttpClient code works well in another project(B) which just created for test. However, when I add this code into my project(A), compile is fine but startup tomcat would throw error:
java.lang.NoClassDefFoundError: javax/ws/rs/ProcessingException
我想知道它是否不是服务，因此无法在服务中使用(DatabaseServiceImpl).所以我将HttpClient作为服务，但仍然出现如下错误:
I was wondering if it isn't a Service so I couldn't use in a service(DatabaseServiceImpl). So I make HttpClient as a service but still got error as below:
[ERROR][localhost-startStop-1][org.springframework.web.context.ContextLoader.initWebApplicationContext():324][14/08/04 12:57:18.287][2927]
Context initialization failed

我导入的lib在两个项目(包括Jersey和Jackson)之间完全相同. 我错过了任何设置以便春天找不到班级吗?
The lib I have imported was totally same between two project, including Jersey and Jackson. Did I miss any setting so that spring couldn't found the class??
谢谢
推荐答案
解决了！！
由于我的项目没有使用Maven或gradle，因此存在很多lib依赖和部署问题.
Due to my project doesn't use Maven or gradle, so many lib dependency and deploy issue.
此问题主要是由Deployment Assembly引起的，右键单击project-> properties-> Deployment Assembly-> add lib，以定义Java EE Web Application项目的打包结构.然后将库部署到web-inf/lib.
This problem mainly cause by Deployment Assembly, right click on project->properties->Deployment Assembly->add lib, to define packaging structure for your Java EE Web Application project. And then the lib would be deploy to web-inf/lib.
谢谢.
