spring AOP 为系统增加操作日志 

方法一：

1.  实现操作日志的类

package com.huaxia.log.interceptor;import java.lang.reflect.Method;import java.util.Date;import javax.servlet.http.HttpServletRequest;import org.apache.commons.lang.StringUtils;import org.apache.log4j.Logger;import org.springframework.aop.MethodBeforeAdvice;import com.huaxia.auth.domain.UserAccount;import com.huaxia.base.service.UserAccountService;import com.huaxia.log.domain.LogNameConfig;import com.huaxia.log.domain.OperateLog;import com.huaxia.log.service.OperateLogService;public class LoggerBefore implements MethodBeforeAdvice {/** * Logger for this class */private static final Logger logger = Logger.getLogger(LoggerBefore.class);/** * OperateLogService */private OperateLogService logService;/** * userAccountService */private UserAccountService userAccountService;/** * @param method * @param objects * @param o * @throws Throwable */public void before(Method method, Object[] objects, Object o)throws Throwable {UserAccount curUser = null;String methodName = "execute";String userIp = null;String sessionId = null;String clazzName = o.getClass().getSimpleName();for (Object obj : objects) {if (null == obj) {continue;}if (obj instanceof HttpServletRequest) {HttpServletRequest request = (HttpServletRequest) obj;if ("LoginAction".equals(clazzName)) {curUser = userAccountService.getUserAccountByUserid(request.getParameter("userID"));} else {curUser = (UserAccount) request.getSession().getAttribute("HUAXIA_CURRENT_USER");}sessionId = request.getSession().getId();if (StringUtils.isNotEmpty(request.getParameter("method"))) {methodName = request.getParameter("method");}userIp = request.getRemoteAddr();break;}}if (null == curUser) {logger.info("can not get session user.");logger.info("logging before:" + o.getClass().getSimpleName()+ methodName);return;}LogNameConfig logCfg = this.logService.getLogNameConfig(clazzName,methodName);if (null != logCfg) {if ("1".equals(logCfg.getLogFlag())) {OperateLog log = new OperateLog();log.setUserId(curUser.getUserID());log.setUserName(curUser.getUserName());log.setOperateTime(new Date());log.setClassName(clazzName);log.setOperateMethod(methodName);log.setUserIp(userIp);log.setSessionId(sessionId);String operateName = logCfg.getOperateCnName();if (null != operateName) {log.setOperateCnName(operateName);}logService.addLog(log);logger.info("userId:" + log.getUserId() + ",userIp:"+ log.getUserIp() + ",className:" + log.getClassName()+ ",operateMethod:" + log.getOperateMethod()+ ",operateTime:" + log.getOperateTime());}}}/** * @param pLogService *            the logService to set */public void setLogService(OperateLogService pLogService) {logService = pLogService;}public void setUserAccountService(UserAccountService userAccountService) {this.userAccountService = userAccountService;}}

2.配置spring.xml文件

<bean name="logger" class="com.huaxia.log.interceptor.LoggerBefore"><property name="logService" ref="logService" /><property name="userAccountService" ref="userAccountService" /></bean><bean name="loggerAutoProxy"class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"><property name="beanNames"><list><value>/*</value></list></property><property name="interceptorNames"><list><value>logger</value></list></property></bean>

方法二：采用注解的方式

1.生成自定义注解

package com.huaxia.traffic.app.common.log;import java.lang.annotation.Documented;import java.lang.annotation.ElementType;import java.lang.annotation.Retention;import java.lang.annotation.RetentionPolicy;import java.lang.annotation.Target;@Target({ ElementType.PARAMETER, ElementType.METHOD })@Retention(RetentionPolicy.RUNTIME)@Documentedpublic @interface SystemControllerLog {    String description() default "";}

2.spring AOP  拦截切入点

package com.huaxia.traffic.app.common.log;import java.lang.reflect.Method;import java.util.Date;import org.apache.log4j.Logger;import org.apache.shiro.SecurityUtils;import org.apache.shiro.subject.Subject;import org.aspectj.lang.JoinPoint;import org.aspectj.lang.annotation.After;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.aspectj.lang.annotation.Pointcut;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;import com.huaxia.traffic.app.common.domain.OperateLog;import com.huaxia.traffic.app.common.log.service.OperateLogService;import com.huaxia.traffic.app.enterprise.domain.EnterpriseOperator;import com.huaxia.traffic.app.enterprise.domain.EnterpriseOperatorLogin;@Component@Aspectpublic class LoggerBefore {    /**     * Logger for this class     */    private static final Logger logger = Logger.getLogger(LoggerBefore.class);    /**     * OperateLogService     */    @Autowired    private OperateLogService logService;    @Pointcut("@annotation(com.huaxia.traffic.app.common.log.SystemControllerLog)")    public void controllerAspect() {    }    @SuppressWarnings("rawtypes")    public static String getControllerMethodDescription(JoinPoint joinPoint) throws Exception {        String targetName = joinPoint.getTarget().getClass().getName();        String methodName = joinPoint.getSignature().getName();        Object[] arguments = joinPoint.getArgs();        Class targetClass = Class.forName(targetName);        Method[] methods = targetClass.getMethods();        String description = "";        for (Method method : methods) {            if (method.getName().equals(methodName)) {                Class[] clazzs = method.getParameterTypes();                if (clazzs.length == arguments.length) {                    description = method.getAnnotation(SystemControllerLog.class).description();                    break;                }            }        }        return description;    }    /**     * @param method     * @param objects     * @param o     * @throws Throwable     */    @After("controllerAspect()")    public void before(JoinPoint joinPoint) throws Throwable {    EnterpriseOperator curUser = null;        String userIp = null;        String sessionId = null;        String clazzName = joinPoint.getTarget().getClass().getName();        String methodName = joinPoint.getSignature().getName();        Object[] objects = joinPoint.getArgs();        Class targetClass = Class.forName(clazzName);        Method[] methods = targetClass.getMethods();        String description = "";        for (Method method : methods) {            if (method.getName().equals(methodName)) {                Class[] clazzs = method.getParameterTypes();                if (clazzs.length == objects.length) {                    description = method.getAnnotation(SystemControllerLog.class).description();                    break;                }            }        }        logger.info("clazzName=" + clazzName + ",method=" + methodName + ",args=" + objects);        Subject subject = SecurityUtils.getSubject();        userIp=subject.getSession().getHost();        sessionId=subject.getSession().getId().toString();        Object user = subject.getPrincipal();        logger.info(user);        if (user instanceof EnterpriseOperator) {            curUser = (EnterpriseOperator) user;            OperateLog log = new OperateLog();            log.setUserId(String.valueOf(curUser.getId()));            log.setUserName(curUser.getUsername());            log.setOperateTime(new Date());            log.setClassName(clazzName);            log.setOperateMethod(methodName);            log.setUserIp(userIp);            log.setSessionId(sessionId);            log.setOperateCnName(description);            logService.addLog(log);        }    }}

3.自定义注解用法

    @ResponseBody    @RequestMapping(value = "/logout")    @SystemControllerLog(description="登出")    public ReturnBean logout(HttpServletRequest request) {        Subject currentUser = SecurityUtils.getSubject();        EnterpriseOperator user = (EnterpriseOperator) currentUser.getPrincipal();        LOGGER.info(ToStringBuilder.reflectionToString(user));        enterpriseOperatorLoginService.invalidToken(user);        if (currentUser.isAuthenticated()) {            currentUser.logout();            //session.invalidate();        }        ReturnBean bean = new ReturnBean();        bean.setSuccess(ReturnBean.SUCCESS);        bean.setData(null);        bean.setMessage("注销用户成功");        return bean;    }

 方法二 可以自己给方法取名字比方法一好用
