【问题描述】：
我使用 Eclipse Kepler，Java 1.7。 我的 pom.xml 的一部分如下。 正如我在 Maven 编译期间看到的那样，根本没有关于编织的日志。我也没有任何错误。 方面也不起作用。 我究竟做错了什么？ 正如我在一些例子中看到的那样，这个 pom 应该可以工作。 我在 Eclipse 中安装了 AspectJ 工具。

编辑： 这是我的方面代码：
package util;
import java.util.logging.Logger;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.springframework.util.StopWatch;
@Aspect
public class MyAspect {
private static final Logger logger = Logger.getLogger(MyAspect.class.getName());
@Around("execution(public * filter.RolesFilter.doFilter(..))")
public Object loggingMethod(ProceedingJoinPoint joinPoint) throws Throwable {
StopWatch stopWatch = new StopWatch();
stopWatch.start();
Object retVal = joinPoint.proceed();
stopWatch.stop();
StringBuffer logMessage = new StringBuffer();
logMessage.append(joinPoint.getTarget().getClass().getName());
logMessage.append(".");
logMessage.append(joinPoint.getSignature().getName());
logMessage.append("(");
// append args
Object[] args = joinPoint.getArgs();
for (int i = 0; i < args.length; i++) {
logMessage.append(args[i]).append(",");
}
if (args.length > 0) {
logMessage.deleteCharAt(logMessage.length() - 1);
}
logMessage.append(")");
logMessage.append(" execution time: ");
logMessage.append(stopWatch.getTotalTimeMillis());
logMessage.append(" ms");
System.out.println(logMessage.toString());
logger.info(logMessage.toString());
return retVal;
}
}
我想用我的方面编织的方法：
package filter;
import java.io.IOException;
import java.util.logging.Logger;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
public class RolesFilter implements Filter {
Logger logger = Logger.getLogger(RolesFilter.class.getName());
public RolesFilter() {
}
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException {
logger.info("This is logger message");
HttpServletRequest req = (HttpServletRequest) request;
HttpServletResponse res = (HttpServletResponse) response;
HttpSession session = req.getSession();
String reqURI = req.getRequestURI();
String userName = (String) session.getAttribute("username");
Character role = (Character) session.getAttribute("role");
try {
if (role != null && role.charValue() == 'A') {
if (reqURI.indexOf("/admin/") >= 0) {
chain.doFilter(request, response);
} else {
res.sendRedirect(req.getContextPath()
+ "/view/roles/admin/home.xhtml");
}
} else if (role != null && role.charValue() == 'B') {
if (reqURI.indexOf("/biller/") >= 0) {
chain.doFilter(request, response);
} else {
res.sendRedirect(req.getContextPath()
+ "/biller.xhtml");
}
} else if (role != null && role.charValue() == 'C') {
if (reqURI.indexOf("/customer/") >= 0) {
chain.doFilter(request, response);
} else {
res.sendRedirect(req.getContextPath()
+ "/customer.xhtml");
}
} else {
res.sendRedirect(req.getContextPath()
+ "/login.xhtml");
}
} catch (ServletException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
另外，这里是maven clean compile 输出：

【问题讨论】：
-
感谢您分享部分 Maven 配置，但应用程序和方面代码在哪里？ Maven 控制台输出在哪里？如果没有这些信息，很难对您的问题说任何明智的事情。请更新您的问题，最好创建并分享一个最小的SSCCE 重现问题，也许在 GitHub 上。
-
请也发布
RolesFilter类（包括包声明）以及mvn clean compile的输出。哦，顺便说一句：如果你在 Spring 中使用原生 AspectJ，是有意还是你真的想使用 Spring AOP？在后一种情况下，方面也应该是 Spring@Component，AFAIK。 -
@kriegaex 感谢您的参与。我两个都加了。关于 AspectJ 和 Spring AOP - 我只是尝试遵循不同的教程。尽管我尝试了我发现的一切，但我未能使其工作。出了点问题，但我无法得到什么。
-
您的 AspectJ Maven 插件未运行。您是否只是将其放入
<pluginManagement>部分但忘记添加实际的<plugins>部分来激活它？ Maven 输出表明了这一点，而您只从 POM 中发布了一个 sn-p，因此很难判断。 -
pluginManagement中的任何内容都只是预配置。您还需要有一个额外的独立plugins部分 outside ofpluginManagement在其中声明您真正想要的预配置插件（没有版本号和配置，只有组和工件 ID）在构建期间使用。这是 Maven 基础知识。
