1.配置log4j配置文件

写一个用户拦截器：

1 package com.heruan.fsmanage.aspect; 2  3 import java.io.IOException; 4 import javax.servlet.Filter; 5 import javax.servlet.FilterChain; 6 import javax.servlet.FilterConfig; 7 import javax.servlet.ServletException; 8 import javax.servlet.ServletRequest; 9 import javax.servlet.ServletResponse;10 import javax.servlet.http.HttpServletRequest;11 import javax.servlet.http.HttpSession;12 import org.apache.log4j.MDC;13 14 import com.heruan.fsmanage.basedevelop.utils.UniqueIdUtil;15 import com.heruan.fsmanage.entity.basedevelop.SysUser;16 /** 17  * @ClassName GetUserFilter18  * @PackageName com.heruan.fsmanage.aspect19  * @Description (得到SESSION中的用户)20  * @author law21  * @Date 2016-5-6 下午3:43:1522  */23 public class GetUserFilter implements Filter {24 25     // 定义默认用户姓名26     private final static String DEFAULT_USER = "guest";27 28     public void destroy() {29     }30 31     public void doFilter(ServletRequest request, ServletResponse response,32             FilterChain chain) throws IOException, ServletException {33         HttpServletRequest req = (HttpServletRequest) request;34         HttpSession session = req.getSession();35         if (session == null) {36             Long id = UniqueIdUtil.getInstanceId();37             MDC.put("userId", id);38             MDC.put("userName", DEFAULT_USER);40         } else {41             SysUser user = (SysUser) session.getAttribute("userinfo");42             if (user == null) {43                 Long id = UniqueIdUtil.getInstanceId();44                 MDC.put("userId", id);45                 MDC.put("userName", DEFAULT_USER);46             } else {47                 MDC.put("userId", user.getId());48                 MDC.put("userName", user.getUserName());49             }50         }51 52         chain.doFilter(request, response);53     }54 55     public void init(FilterConfig Config) throws ServletException {56 57     }58 }

自定义注解：

package com.heruan.fsmanage.annotation;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;/**  * @ClassName Action * @PackageName com.heruan.fsmanage.annotation * @Description 对方法信息进行描述 * @author law * @Date 2016-5-25 下午4:23:04 */@Target({ElementType.METHOD})@Retention(RetentionPolicy.RUNTIME)@Documentedpublic @interface Action {    String description() default  "";}

写基于注解的切面：

加入一条bean：

启用aop注解代理：
