@InputOutputProxy

Posted by Bruce Tsai

說明

透過 AOP 記錄呼叫的方法中輸入及輸出的內容。可設定僅記錄輸出或僅記錄輸入內容。需在 spring 設定中設定 AOP 相關的設定，配合 InputOutputAdvice 使用。

範例

• spring 設定檔

<aop:config proxy-target-class="true">

    <aop:pointcut
      id="inputOutputProxy"
      expression="execution(* com.fet.crm.eservice..*.*(..))
      and (@within(foundation.core.generic.annotation.aop.InputOutputProxy) 
      or @annotation(foundation.core.generic.annotation.aop.InputOutputProxy))"
    />

    <aop:advisor
      advice-ref="inputOutputAdvice"
      pointcut-ref="inputOutputProxy" />

</aop:config>

<bean id="inputOutputAdvice"
      class="foundation.core.generic.aop.InputOutputAdvice">
    <property name="enabled" value="true" />
</bean>

• 程式用例

@Component
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public class Executor {

    @InputOutputProxy
    public CharSequence execute(String name, Date date) {
        return String.format("%s=%s", name, date);
    }

}

public class Program

    public static void main(String[] args) {
        Context context = Contexts.Load();
        Executor executor = context.getBean(Executor.class);
        executor.execute("bruce", new Date());
    }
}

輸出結果

輸入參數[Executor.execute()] => {
    [java.lang.String] "bruce"
    [java.util.Date] "Dec 12, 2015 7:14:51 PM"
}

回傳值[Executor.execute()] => [java.lang.CharSequence]
    "bruce\u003dSat Dec 12 19:14:51 CST 2015"
