我试图在eclipse 4.4.0(Luna)中使用aspectJ.Y找不到适合这个版本的eclipse的任何ajdt插件.

无论如何我认为aspectj应该工作,所以我将aspectj jar放在我的webApp的lib目录中,并创建这个Aspect类:

@Aspect
public class LoggerAspect {

    @Before("(execution(* *.*(..))")
    public void intercept(JoinPoint jp) {
        System.out.print("before");
    }

    @After("(execution(* *.*(..))")
    public void afterReturning(JoinPoint jp) {
        System.out.print("after");
    }

    @AfterThrowing(pointcut = "execution(* *.*(..))")
    public void logException(JoinPoint jp, Exception t) {
        System.out.print("throwing");
    }
}

但没有记录任何东西.我错过了什么？

我在一张桌子上做了几次插入.现在,我已经迭代了一个对象列表,对于每个对象,我使用insert语句执行ExecuteNonQuery.

我想知道是否有紧固的方法来做到这一点.这样,插入800个寄存器需要几分钟.

我在Java中使用了executeBatch方法,对于这个提议,c#中有类似的东西.

问候 !

我试图从Web应用程序(eclispe中的动态Web应用程序)中使用Jersey Rest服务,如下所示:

Client client = ClientBuilder.newBuilder().build(); // Here is the error

WebTarget target = client.target("url/rest").path("List");

String result = target.request(MediaType.TEXT_PLAIN).get(String.class);

在ClientBuilder.newBuilder()行中进行调试时,系统抛出ClassNotFoundException:javax.ws.rs.client.ClientBuilder错误,但java项目中的相同代码完美无缺.
