使用标签来设置需要的记录

实例：@ISystemLog()

@Controller@RequestMapping("test")public class TestController {    @RequestMapping(value = "test.do", method = RequestMethod.GET)    @ISystemLog(module = "TestController",methods = "test")    public ModelAndView test(HttpServletRequest request, HttpServletResponse response) throws Exception {        HttpServletRequest request1 = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();        return new ModelAndView("/login");    }}

创建ISystemLog

package com.helka.cmis.common.utils.log;import java.lang.annotation.*;@Target({ElementType.PARAMETER, ElementType.METHOD})@Retention(RetentionPolicy.RUNTIME)@Documentedpublic @interface ISystemLog {    String module()  default "";    String methods()  default "";}

创建LogAopAction

package com.helka.cmis.common.utils.log;import com.helka.cmis.common.utils.LogEntity;import org.aspectj.lang.ProceedingJoinPoint;import org.aspectj.lang.Signature;import org.aspectj.lang.annotation.After;import org.aspectj.lang.annotation.AfterReturning;import org.aspectj.lang.annotation.AfterThrowing;import org.aspectj.lang.annotation.Around;import org.aspectj.lang.annotation.Aspect;import org.aspectj.lang.annotation.Before;import org.aspectj.lang.annotation.Pointcut;import org.aspectj.lang.reflect.MethodSignature;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.context.request.RequestContextHolder;import org.springframework.web.context.request.ServletRequestAttributes;import org.springframework.web.context.request.ServletWebRequest;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import java.lang.reflect.Method;import java.text.SimpleDateFormat;import java.util.Date;@Aspectpublic class LogAopAction {//    @Resource(name="logService")//    private LogServiceImpl logservice;    //配置接入点,如果不知道怎么配置,可以百度一下规则    @Pointcut("execution(* com.kintech.*.controller..*.*(..))")    private void controllerAspect(){}//    @Autowired//    private  HttpServletRequest request;    //@Around("execution(* org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter.handle(..))")    @Around("controllerAspect()")    public Object around(ProceedingJoinPoint pjp) throws Throwable {        //常见日志实体对象        LogEntity log = new LogEntity();        //获取登录用户账户        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();        ServletWebRequest servletWebRequest=new ServletWebRequest(request);        HttpServletResponse response=servletWebRequest.getResponse();        String name = (String) request.getSession().getAttribute("USER_ID");        log.setAccount(name);        //获取系统时间        String time = new SimpleDateFormat("YYYY-MM-dd HH:mm:ss").format(new Date());        log.setCreatetime(time);        String ip = request.getHeader("X-Real-IP");        log.setIp(ip);        long start = System.currentTimeMillis();        // 拦截的实体类，就是当前正在执行的controller        Object target = pjp.getTarget();        // 拦截的方法名称。当前正在执行的方法        String methodName = pjp.getSignature().getName();        // 拦截的方法参数        Object[] args = pjp.getArgs();        // 拦截的放参数类型        Signature sig = pjp.getSignature();        MethodSignature msig = null;        if (!(sig instanceof MethodSignature)) {            throw new IllegalArgumentException("该注解只能用于方法");        }        msig = (MethodSignature) sig;        Class[] parameterTypes = msig.getMethod().getParameterTypes();        Object object = null;        // 获得被拦截的方法        Method method = null;        try {            method = target.getClass().getMethod(methodName, parameterTypes);        } catch (NoSuchMethodException e1) {            // TODO Auto-generated catch block            e1.printStackTrace();        } catch (SecurityException e1) {            // TODO Auto-generated catch block            e1.printStackTrace();        }        if (null != method) {            // 判断是否包含自定义的注解，说明一下这里的SystemLog就是我自己自定义的注解            if (method.isAnnotationPresent(ISystemLog.class)) {                ISystemLog systemlog = method.getAnnotation(ISystemLog.class);                log.setModule(systemlog.module());                log.setMethod(systemlog.methods());                try {                    object = pjp.proceed();                    long end = System.currentTimeMillis();                    //将计算好的时间保存在实体中                    log.setUsedtime(end-start);                    log.setCommit("Success！");                    //保存进数据库                    //logservice.saveLog(log);                } catch (Throwable e) {                    // TODO Auto-generated catch block                    long end = System.currentTimeMillis();                    log.setUsedtime(end-start);                    log.setCommit("Failed");                    //logservice.saveLog(log);                }            } else {//没有包含注解                object = pjp.proceed();            }        } else { //不需要拦截直接执行            object = pjp.proceed();        }        return object;    }}

创建数据库的映射实体

public class LogEntity {    private int id;    private String account;    private String module;    private String method;    private long usedtime;    private String ip;    private String createtime;    private String commit;    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    public String getAccount() {        return account;    }    public void setAccount(String account) {        this.account = account;    }    public String getModule() {        return module;    }    public void setModule(String module) {        this.module = module;    }    public String getMethod() {        return method;    }    public void setMethod(String method) {        this.method = method;    }    public long getUsedtime() {        return usedtime;    }    public void setUsedtime(long usedtime) {        this.usedtime = usedtime;    }    public String getIp() {        return ip;    }    public void setIp(String ip) {        this.ip = ip;    }    public String getCreatetime() {        return createtime;    }    public void setCreatetime(String createtime) {        this.createtime = createtime;    }    public String getCommit() {        return commit;    }    public void setCommit(String commit) {        this.commit = commit;    }}

配置文件：

springmvc-servlet.xml

<aop:aspectj-autoproxy proxy-target-class="true" />    <bean id="logAopAction" class="com.helka.cmis.common.utils.log.LogAopAction" />
