aop 记录用户操作（一）

转载： http://www.cnblogs.com/guokai870510826/p/5981015.html

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)
@Documented
public @interface ISystemLog {
    String module()  default "";
    String methods()  default "";
}

创建LogAopAction

@Aspect

    //配置接入点,如果不知道怎么配置,可以百度一下规则

    //@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;
    }

}
