Question

我的Spring配置xml文件中有以下aspectJ定义

<bean id="valueLogging" class="org.beans.ValueLogging">
     <constructor-arg value="#{T(System).out}" />
</bean>

<aop:config>
    <aop:aspect ref="valueLogging">
        <aop:pointcut id="settingValue" expression="execution(* *.setValue(..)) and args(parameter, value)"/>

        <aop:after pointcut-ref="settingValue" method="logAfterSettingAValue" />
    </aop:aspect>
</aop:config>

然后，我有ValueLogging类：

public class ValueLogging {

    private PrintStream stream;

    public ValueLogging(PrintStream stream) {
        this.stream = stream;
    }

    public void logAfterSettingAValue(final Object element, final String parameter, final Double value) {
        stream.println(element + " :The value " + value + " has been set to the parameter " + parameter.getName());
    }

}

我收到初始化错误。以下是跟踪的一部分：

我认为这是因为我无法捕获方法的调用者以将其作为logAfterSettingAValue方法的参数。有什么想法吗？

AspectJ获取调用方法及其参数的对象
