通过切面实现相关业务逻辑

一、xml配置　　

<aop:aspectj-autoproxy proxy-target-class="true"></aop:aspectj-autoproxy>
<bean id="logAspect" class="com.ucfgroup.framework.web.app.aspect.LogAspect" />
<aop:config>
    <!-- 配置切点表达式 -->
    <aop:pointcut id="pointcut" expression="execution(* com.ucfgroup.framework.web.app.*.controller.*.*(..))" />
    <aop:aspect order="1" ref="logAspect">
        <!-- 前置通知 -->
        <aop:before method="logManager" pointcut-ref="pointcut" />
    </aop:aspect>
</aop:config>

二、java代码

package com.ucfgroup.framework.web.app.aspect;

import java.util.Date;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;
import java.util.Map.Entry;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.apache.log4j.Logger;
import org.aspectj.lang.JoinPoint;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.util.StringUtils;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import com.ucfgroup.framework.utils.WebUtil;
import com.ucfgroup.framework.web.app.personal.entity.PUserZt;

import com.ucfgroup.framework.web.app.usrmgmt.entity.TOperLog;
import com.ucfgroup.framework.web.app.usrmgmt.entity.TuUser;
import com.ucfgroup.framework.web.log.model.OperLog;

public class LogAspect {
    @Autowired
    private TOperLogMapper tOperLogMapper;
    protected Logger LOG = Logger.getLogger(getClass());

    public void logManager(JoinPoint joinPoint) throws Exception {
        // 记录日志失败不影响业务继续
        try {

            // // 接收到请求，记录请求内容
            ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder
                    .getRequestAttributes();
            HttpServletRequest request = attributes.getRequest();

            HttpSession session = request.getSession();
            PUserZt zt = (PUserZt) session.getAttribute("ZTModel");
            TuUser tuUser = (TuUser) session.getAttribute("USER_INFO");

            // check if user is login
            Authentication auth = SecurityContextHolder.getContext().getAuthentication();

            // 记录日志失败不影响业务继续

            String method = joinPoint.getSignature().getName();
            TOperLog tOperLog = new TOperLog();
            if (null != tuUser) {
                tOperLog.setUsername(tuUser.getUsername());
            }
            if (null != zt) {
                // log.setBranchNo(zt.getBranchNo());
                tOperLog.setClientId(zt.getZtid());
            }
            tOperLog.setBrowserAgent(request.getHeader("user-agent"));
            tOperLog.setIpAddress(WebUtil.getIpAddr(request));
            tOperLog.setMethod(StringUtils.hasText(method) ? method.replace("do", "").toUpperCase() : "");
            tOperLog.setOperationTime(new Date(System.currentTimeMillis()));
            tOperLog.setReqMsg(getReqMsg(request));
            tOperLog.setResUrl(request.getServletPath());

            if ("GET".equals(tOperLog.getMethod()) || "HEAD".equals(tOperLog.getMethod())
                    || "OPTIONS".equals(tOperLog.getMethod())) {
                tOperLog.setLogType(OperLog.ACCESS_LOG);
            } else {
                tOperLog.setLogType(OperLog.UPDATE_LOG);
            }

            tOperLogMapper.insert(tOperLog);
        } catch (Throwable e) {
            LOG.error("Save log failed: " + e.getMessage(), e);
        }
    }

    private String getReqMsg(HttpServletRequest request) {
        Map<String, String> paraMap = getReqParams(request);
        StringBuilder parameterStr = new StringBuilder();
        boolean first = true;
        for (Entry<String, String> entry : paraMap.entrySet()) {
            if (!first) {
                parameterStr.append("&");
            } else {
                first = false;
            }
            String value = entry.getValue();
            parameterStr.append(entry.getKey()).append("=");

            // 隐藏 password 域
            if (entry.getKey().toLowerCase().contains("password")) {
                parameterStr.append("********");
            } else {
                parameterStr.append(value);
            }
        }
        return parameterStr.toString();
    }

    private Map<String, String> getReqParams(HttpServletRequest request) {
        Map<String, String> reqParams = new HashMap<String, String>();

        // trim the parameters
        Iterator<String> it = request.getParameterMap().keySet().iterator();
        while (it.hasNext()) {
            String key = it.next();
            // 密码不做trim()
            if (key.toLowerCase().contains("password")) {
                reqParams.put(key, request.getParameter(key));
            } else {
                reqParams.put(key, request.getParameter(key).trim());
            }
        }
        return reqParams;
    }
}

三、总结

Aop的内容非常丰富，由于时间原因，我先将亲测可行的代码记录下来，以后我会慢慢丰富其内容的，毕竟知识越辨越明。
