spring-aop - 不触发切入点

Question

我有一个 Spring 3.2.4 MVC 应用程序，我想使用 Spring AOP。因此，我创建了一个带有<aop:aspectj-autoproxy />.

我还写了一个 Aspect （采用在网络上找到的代码）：

@Component
@Aspect
public class PerformanceMonitoring {
    private static final Logger logger = Logger.getLogger(PerformanceMonitoring.class);

    public PerformanceMonitoring() {
        System.out.println("++++++++++++++++++++++++++++++++++++++++++++++++");
    }

//    @Around("execution(* com.silabs.moka.*(..))")
//    @Pointcut(value="execution(public * *(..))")
//    @Before("execution(* * com.foo.bar.controller.*.*(..))")
    @Before("execution(public DefaultClientResponse<UserProfile> com.foo.bar.controller.LoginLogoutController.login(..))")
    public void xyz(JoinPoint joinPoint) {
        Signature signature = joinPoint.getSignature();
        String methodName = signature.getName();
        String stuff = signature.toString();
        String arguments = Arrays.toString(joinPoint.getArgs());
        System.out.println("################################################");
        logger.info("Write something in the log... We are just about to call method: "
            + methodName + " with arguments " + arguments + "\nand the full toString: "
            + stuff);
    }
}

（我实现构造函数只是为了查看 bean 是否在 TOMCAT 启动期间被实例化……确实如此！）

但是，每当我输入 LoginLogoutController 的登录方法时，我的 Aspect 的 xyz 方法都不会执行。我的Pointcut的表达是不是错了？

我如何告诉 Spring 执行我的建议？

我的控制器：

@Controller
@PropertySource("classpath:xxx.properties")
public class LoginLogoutController {

private static final Logger logger = Logger.getLogger(LoginLogoutController.class);
@Inject
protected Environment env;

/**
 * Returns a json list of first names.
 *
 * @param term the beginning part of the first name
 * @return json string array of first names
 */
@RequestMapping(value = "/login", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public DefaultClientResponse<UserProfile> login(final @RequestParam String userName, final @RequestParam String passWord, final @RequestParam(required = false) String deviceToken, HttpServletRequest req) {

    logger.info("login: " + userName + ", passWord: " + passWord + ", deviceToken: " + deviceToken);
//        logger.info("Communicating with host: " + env.getProperty("url.base"));

    UserProfile up = null;
    up = userProfileService.findUserProfileByNameAndPassword(userName, passWord);

    if (up != null) {
        logger.info("UserProfile for " + up.getFirstName() + " " + up.getLastName() + " found.");
        HttpSession session = req.getSession(true);
        logger.info("Created session with ID:[" + session.getId() + "]");

        // Set session parameters
        session.setMaxInactiveInterval(Integer.valueOf(env.getProperty("xxx.session.timeout")) * 60 * 60);
        session.setAttribute("isAuthenticated", true);
        session.setAttribute("deviceToken", deviceToken);
        session.setAttribute("authInfo", up.getAuthInfo());
        session.setAttribute("KundenID", up.getUserProfileId());
...

        return new DefaultClientResponse<UserProfile>(session.getId(), 0, "", up);
    } else {
        return new DefaultClientResponse<UserProfile>(null, 1, String.format("No user for gogin <%1$s> and password <%2$s> registered.", userName, passWord), null);
    }
}
}

我已将大型 appConfig-context.xml 拆分为较小的部分：

根配置.xml
tx-context.xml
aop-context.xml
appConfig-context.xml（DispatcherServlet 的 MVC 上下文）

虽然在 web.xml 中有这个：

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/aop-context.xml 
                     /WEB-INF/spring/root-context.xml 
                     /WEB-INF/spring/tx-context.xml
        </param-value>
    </context-param>

at least the aop-context.xml seems not to be considered. When I import aop-context.xml in appConfig-context.xml using <beans:import resource="../aop-context.xml"/> I always get a

HTTP Status 404 - /bar/WEB-INF/views/.jsp

type Status report

message /bar/WEB-INF/views/.jsp

from TOMCAT in the browser. description The requested resource is not available.

I never succeeded in having both Spring MVC (for my @Controller classes) and all the other nice AOP stuff (such as @Transactional) in one class. This might be just the cause here as well, but that’s a guess given we do not see all the setup.

Extended answer (now that config is given):

You have these three for the same context:

<aop:aspectj-autoproxy />
<mvc:annotation-driven />
<tx:annotation-driven mode="aspectj" transaction-manager="transactionManager" />

You should have separate contexts for controllers and everything else. Please have a look at @Service are constructed twice for reference to do it correctly. AOP (and thus transactions) will not work in the context for controllers.
