自定义一个注解用于记录操作日志

1.先自定义一个注解：代码如下:

import java.lang.annotation.*;

@Retention(RetentionPolicy.RUNTIME)

@Target({ElementType.TYPE,ElementType.METHOD})

@Documented

public @interface FilterAnnotation {

String desc();//用户接口描述

}

2.写一个aop

import java.io.IOException;

import java.util.Date;

import javax.servlet.http.HttpServletRequest;

import org.aspectj.lang.annotation.Aspect;

import org.aspectj.lang.annotation.Before;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Component;

import org.springframework.web.context.request.RequestAttributes;

import org.springframework.web.context.request.RequestContextHolder;

import org.springframework.web.context.request.ServletRequestAttributes;

import com.xinge.model.OperateLog;

import com.xinge.model.User;

import com.xinge.service.OperateLogService;

@Aspect

@Component

public class OperateLogAop {

@Autowired

OperateLogService operateLogService;

@Before("within(com.xinge.controller..*) && @annotation(filterAnnotation)")

public void getInfo(FilterAnnotation filterAnnotation) throws IOException {

RequestAttributes ra = RequestContextHolder.getRequestAttributes();

ServletRequestAttributes sra = (ServletRequestAttributes) ra;

HttpServletRequest request = sra.getRequest();

String uri = request.getRequestURI();

//从session获取用户信息

User user = (User) request.getSession().getAttribute("user");

if (user != null) {

OperateLog operateLog= new OperateLog();

operateLog.setCreateTime(new Date());

operateLog.setUsername(user.getUsername());

operateLog.setAction(uri);

operateLog.setIp(getIpAddress(request));

operateLog.setDescription(filterAnnotation.desc());

operateLogService.add(operateLog);

}

}

/**

* 获取ip

* @param request

* @return

* @throws IOException

*/

public final static String getIpAddress(HttpServletRequest request) throws IOException {

// 获取请求主机IP地址,如果通过代理进来，则透过防火墙获取真实IP地址

String ip = request.getHeader("X-Forwarded-For");

if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

ip = request.getHeader("Proxy-Client-IP");

}

if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

ip = request.getHeader("WL-Proxy-Client-IP");

}

if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

ip = request.getHeader("HTTP_CLIENT_IP");

}

if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

ip = request.getHeader("HTTP_X_FORWARDED_FOR");

}

if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {

ip = request.getRemoteAddr();

}

} else if (ip.length() > 15) {

String[] ips = ip.split(",");

for (int index = 0; index < ips.length; index++) {

String strIp = (String) ips[index];

if (!("unknown".equalsIgnoreCase(strIp))) {

ip = strIp;

break;

}

}

}

return ip;

}

}

3.使用的时候只需在方法上加入注解就行

@FilterAnnotation(desc = "添加用户信息")

@RequestMapping(value = "/add", method = RequestMethod.POST)

public Object add(@User user)
