Spring AOP 对（增删节）操作记录日志

以下程序记录增删改操作
1.目标类LoginService.java

?

public class LogService {

    @SuppressWarnings("unchecked")
    public void logOption(JoinPoint jp) {
        StringBuilder str = new StringBuilder();
        str.append("method:" + jp.getSignature().getName() + "\n");

        HttpServletRequest request = ServletActionContext.getRequest();
        Iterator<Entry<String, Object>> it = request.getParameterMap()
                .entrySet().iterator();
        boolean isFirst = true;
        str.append(" param:");
        while (it.hasNext()) {
            Entry<String, Object> entry = it.next();
            if (isFirst) {
                isFirst = false;
            } else {
                str.append(";");
            }
            str.append(entry.getKey() + "=");
            Object[] allValue = (Object[]) entry.getValue();
            for (int i = 0; i < allValue.length; i++) {
                if (i != 0) {
                    str.append(",");
                }
                str.append(allValue[i].toString());
            }
        }

        System.out.println(str.toString());
    }
}

2.在applicationContext.xml进行配置

?

<!-- 目标类 -->

    <bean id="logService" class="com.iteye.blog.service.LogService"></bean>
    <!-- 声名式事务 -->   

     <aop:config>
        <aop:aspect id="myAspect" ref="logService">
            <aop:pointcut  

                <!-- 注意：这里要写拦截方法的路径 -->         
                expression="execution(* com.iteye.blog.service.*.save*(..))||execution(* com.iteye.blog.service.*.delete*(..))||com.iteye.blog.service.*.update*(..))"
                id="logPointCut" />
            <aop:after method="logOption" pointcut-ref="logPointCut" />
        </aop:aspect>
    </aop:config>

?注意：建议使用<aop:config proxy-target-class="true" />，使用CGLIB代理类
