我有一个移植到Google App Engine（GAE）的应用程序。代码之前正在运行，但是现在我在部署到GAE时遇到了处理HTTP请求的错误（“java.lang.IllegalStateException”）。注入时的错误似乎与类路径中缺少相关的东西。
这是callstack：

如果我正确阅读，我认为它无法加载“javax.servlet.http.HttpServletRequest”。
所以奇怪的是，在 DevAppServer 上本地运行正常。我加倍检查，我确实有一个设置为提供的依赖在pom中：
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>${servlet.api.version}</version>
<scope>provided</scope>
</dependency>
即使我将其更改为编译并重新部署，我仍然会收到错误消息。我的理解是servlet类在SDK中的位置，这就是它设置为提供的原因，如果你在Eclipse中的Maven Dependencies下检查了SDK，你可以看到这些类。
该应用程序的早期版本已部署且运行正常，这在尝试将更新推送到GAE时发生。我不知所措，因为我已经对这几个小时进行了故障排除，所以我想也许有人可能会有一些想法来帮我弄清楚发生了什么......
编辑：我尝试将杰克逊更新到最新版本，但这会导致泽西岛代码中出现其他问题。
修改 我认为这个问题与注射有关。我有一个非常简单的[现在]异常映射器类：
package <redacted>;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.ServletContext;
import javax.ws.rs.NotAcceptableException;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.HttpHeaders;
import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;
import org.apache.commons.lang3.StringUtils;
@Provider
public class GenericExceptionMapper implements ExceptionMapper<Throwable> {
private static final Logger logger = Logger.getLogger(GenericExceptionMapper.class.getName());
//@Context HttpHeaders headers;
@Context
ServletContext context;
/*
* (non-Javadoc)
*
* @see javax.ws.rs.ext.ExceptionMapper#toResponse(java.lang.Throwable)
*/
@Override
public Response toResponse(Throwable ex) {
logger.log(Level.SEVERE, ex.getMessage(), ex);
return Response.serverError().status(msg.getStatus().getStatusCode()).entity(msg).build();
}
}
如果我保留原样，这个映射器工作正常，但如果我取消注释该行：
// @ Context HttpHeaders标头;
它再次开始失败。
