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 />的配置文件。
我也写了一个方面（采用网络上的代码）：
@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);
}
}
（我实现了构造函数只是为了看看bean是否在TOMCAT开始时实例化了...... 并且它是！）
但是，每当我输入LoginLogoutController的login方法时，我的Aspect的xyz方法都不会被执行。我的Pointcut表达式错了吗？
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拆分为更小的部分：
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>
至少不考虑aop-context.xml。当我使用<beans:import resource="../aop-context.xml"/>在appConfig-context.xml中导入aop-context.xml时，我总是得到一个
HTTP状态404 - /bar/WEB-INF/views/.jsp
输入状态报告
消息/bar/WEB-INF/views/.jsp
来自浏览器中的TOMCAT。 description请求的资源不可用。
答案 0 :(得分：1)
我从未成功地将Spring MVC（对于我的@Controller类）和所有其他好的AOP内容（例如@Transactional）放在一个类中。这也可能只是原因，但这是猜测，因为我们没有看到所有设置。
扩展答案（现在已提供配置）：
你有三个相同的背景：
<aop:aspectj-autoproxy />
<mvc:annotation-driven />
<tx:annotation-driven mode="aspectj" transaction-manager="transactionManager" />
您应该为控制器和其他所有内容设置单独的上下文。请查看@Service are constructed twice以获取正确执行的参考。 AOP（以及事务）在控制器的上下文中不起作用。
