Spring: Standard Logging aspect (interceptor)
提问by Sergii Zagriichuk
I've found a lot of examples on how to create a custom aspect for logging using the Spring framework like thisor thisbut did not find standard/common Spring implementation for this situation and question. Are there any standard implementations of logging aspect from Spring or not?
我找到了很多关于如何使用像这样或这样的 Spring 框架创建用于日志记录的自定义方面的示例，但没有找到针对这种情况和问题的标准/通用 Spring 实现。是否有来自 Spring 的日志方面的任何标准实现？

Yes there are!
是的有！
<bean id="customizableTraceInterceptor" class="org.springframework.aop.interceptor.CustomizableTraceInterceptor">
<property name="enterMessage" value="Entering $[methodName]($[arguments])"/>
<property name="exitMessage" value="Leaving $[methodName](): $[returnValue]"/>
</bean>
<aop:config>
<aop:advisor advice-ref="customizableTraceInterceptor" pointcut="execution(public * BankAccountServlet.*(..))"/>
</aop:config>
Check out the CustomizableTraceInterceptorAPI, you can define separate enter/exit/exception messages with several placeholders:
查看CustomizableTraceInterceptorAPI，您可以使用多个占位符定义单独的进入/退出/异常消息：
$[methodName]- replaced with the name of the method being invoked$[targetClassName]- replaced with the name of the class that is the target of the invocation$[targetClassShortName]- replaced with the short name of the class that is the target of the invocation$[returnValue]- replaced with the value returned by the invocation$[argumentTypes]- replaced with a comma-separated list of the short class names of the method arguments$[arguments]- replaced with a comma-separated list of the String representation of the method arguments$[exception]- replaced with the String representation of any Throwable raised during the invocation$[invocationTime]- replaced with the time, in milliseconds, taken by the method invocation
$[methodName]- 替换为正在调用的方法的名称$[targetClassName]- 替换为作为调用目标的类的名称$[targetClassShortName]- 替换为作为调用目标的类的短名称$[returnValue]- 替换为调用返回的值$[argumentTypes]- 替换为以逗号分隔的方法参数的短类名称列表$[arguments]- 替换为方法参数的字符串表示的逗号分隔列表$[exception]- 替换为调用期间引发的任何 Throwable 的字符串表示$[invocationTime]- 替换为方法调用所花费的时间（以毫秒为单位）

Here are the list of frameworks that do logging via AOP:
以下是通过 AOP 进行日志记录的框架列表：
http://aspect4log.sf.net- does very nice looking logging via slf4j and @Log annotation. Can work via SpringAOP, and AspectJ. With AspectJ it works even for private methods and constructors and does not require a class to be a Spring Bean. Very easy to use, i was able to make it running with my project within 5 min.
http://aspect4log.sf.net- 通过 slf4j 和 @Log 注释做非常漂亮的日志记录。可以通过 SpringAOP 和 AspectJ 工作。使用 AspectJ，它甚至适用于私有方法和构造函数，并且不需要类是 Spring Bean。非常易于使用，我能够在 5 分钟内使其与我的项目一起运行。
http://loggifier.unkrig.de- does logging via java.util.logging, a bit too complex and not that well document but claims that it can instrument already compiled jar/war/ear files!
http://loggifier.unkrig.de- 通过 java.util.logging 进行日志记录，有点太复杂而且文档不太好，但声称它可以检测已编译的 jar/war/ear 文件！
AbstractTraceInterceptor (from SpringAOP) and it's subclasses SimpleTraceInterceptor and CustomizableTraceInterceptor. Logging configuration is done separately from classes. Logs via commons-logging. Since it is designed for SpringAOP you have to work with Spring Beans (and only with Spring Beans public methods).
AbstractTraceInterceptor（来自 SpringAOP）及其子类 SimpleTraceInterceptor 和 CustomizableTraceInterceptor。日志配置与类分开完成。通过 commons-logging 记录日志。由于它是为 SpringAOP 设计的，因此您必须使用 Spring Beans（并且只能使用 Spring Beans 公共方法）。
