spring AOP 拦截日志
1 首先引入jar包
spring.jar aopalliance.jar aspectjrt.jar aspectjtools.jar aspectjweaver.jar cglib-nodep-2.1_3.jar cglib-src-2.2.jar 这些个jar包不一定都用得上,但离配置到现在整理已经比较久了 有点忘了.
2 spring 配置文件头

3 定义 aop拦截
<aop:aspectj-autoproxy proxy-target-class="true" />
<aop:config proxy-target-class="true">
<aop:aspect ref="logMonitor">
<aop:pointcut id="actionPointcut" expression="execution(* com.*.*.*.service.impl.*.create*(..)) || execution(* com.*.*.*.service.impl.*.update*(..)) || execution(* com.*.*.*.service.impl.*.delete*(..))|| execution(* com.*.*.*.service.impl.*.insert*(..))||execution(* com.*.*.service.impl.*.create*(..)) || execution(* com.*.*.service.impl.*.update*(..)) || execution(* com.*.*.service.impl.*.delete*(..))|| execution(* com.*.*.service.impl.*.insert*(..))"/>
<aop:before pointcut-ref="actionPointcut" method="writeLogInfo" />
</aop:aspect>
</aop:config>
<bean id="logMonitor" parent="baseTransactionProxy">
<property name="target">
<bean
class="com.*.common.userlog.monitor.LogMonitor">
<property name="userLogInfoService">
<ref bean="userLogInfoService" />
</property>
</bean>
</property>
</bean>
4 处理拦截的类logMonitor
@Aspect
public class LogMonitor {
/** * 保存变量的ThreadLocal，保持在同一线程中同步数据. */
private static final ThreadLocal SESSION_MAP = new ThreadLocal();
private IUserLogInfoService userLogInfoService;
public IUserLogInfoService getUserLogInfoService() {
return userLogInfoService;
}
public void setUserLogInfoService(IUserLogInfoService userLogInfoService) {
this.userLogInfoService = userLogInfoService;
}
/**
* 获得线程中保存的属性.
*
* @param attribute
* 属性名称
* @return 属性值
*/
public static Object get(String attribute) {
Map map = (Map) SESSION_MAP.get();
return map.get(attribute);
}
/**
* 记录日志信息
* @param joinpoint
* @throws Exception
* @throws IllegalAccessException
*/
public void writeLogInfo(JoinPoint joinpoint) throws Exception, IllegalAccessException {
UserInfoVO sysUse = (UserInfoVO) UserSession.get(Contents.SESSION_USER_KEY);
// 在基类action中 设用户信息
// UserSession.set(Contents.SESSION_USER_KEY, userVO);
// UserSession.set(Contents.SESSION_USER_IP, request.getRemoteAddr());
String userIP = (String) UserSession.get(Contents.SESSION_USER_IP);
String temp = joinpoint.getStaticPart().toShortString();
// 获得操作类
String classType = joinpoint.getTarget().getClass().getName();
// 获得方法名称
String methodName = temp.substring(10, temp.length() - 1);
Class className = Class.forName(classType);
// 获得方法的参数类型数组
Object[] a = joinpoint.getArgs();
Class[] o = new Class[a.length];//
for (int i = 0; i < a.length; i++) {
o[i] = a[i].getClass();
}
Method method = className.getMethod(methodName, o);
LogDesc desc = method.getAnnotation(LogDesc.class);
// 获得方法的操作动作类型说明
String actionDesc = "";
if (desc != null) {
actionDesc = desc.actionDesc();
}
// 记录日志信息
UserLogInfo userLogInfo = new UserLogInfo();
if (sysUse != null) {
userLogInfo.setUserID(sysUse.getUserID());
userLogInfo.setUserIp(userIP);
userLogInfo.setOperateClass(classType);
userLogInfo.setOperateMethod(methodName);
//设置为一般日志信息标识位
userLogInfo.setEnableFlag("C");
userLogInfo.setOperateDescribe(actionDesc);
}
userLogInfoService.addUserLog(userLogInfo);
}
5 定义取得拦截方法描述的类
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface LogDesc {
String actionDesc();
}
6 在每个需要拦截的方法头加上
/**
* 注册新用户
*
* @roseuid 3C30BD930399
*/
@LogDesc(actionDesc = "新建会员")
public MemberVO createMember(MemberVO memberVO) throws SysComException {
return memberRegisterDao.createMember(memberVO);
}
7 设置、取得用户信息
public class UserSession{
// private static ThreadLocal<Object> threadLocal = new ThreadLocal<Object>();
//
// public HttpServletRequest getContext(){
// return (HttpServletRequest)threadLocal.get();
// }
// public void setContext(HttpServletRequest request){
// threadLocal.set(request);
// }
//
// public void cleanContext(){
// threadLocal.set(null);
// }
/** * 保存变量的ThreadLocal，保持在同一线程中同步数据. */
private static final ThreadLocal SESSION_MAP = new ThreadLocal();
/** * 工具类的protected构造方法. */
protected UserSession() {
}
/**
* 获得线程中保存的属性.
*
* @param attribute
* 属性名称
* @return 属性值
*/
public static Object get(String attribute) {
Map map = (Map) SESSION_MAP.get();
//System.out.println(map.toString());
// System.out.println(map.containsKey("usersession"));
return map.get(attribute);
}
/**
* 获得线程中保存的属性，使用指定类型进行转型.
*
* @param attribute
* 属性名称
* @param clazz
* 类型
* @param <T>
* 自动转型
* @return 属性值
*/
public static <T> T get(String attribute, Class<T> clazz) {
return (T) get(attribute);
}
/**
* 设置制定属性名的值.
*
* @param attribute
* 属性名称
* @param value
* 属性值
*/
public static void set(String attribute, Object value) {
Map map = (Map) SESSION_MAP.get();
if (map == null) {
map = new HashMap();
SESSION_MAP.set(map);
}
map.put(attribute, value);
}
8 另外在配置aop必须是接口的， 否则会出错
看是否可以在action设置拦截效果应该更好的。
