Spring Boot AOP记录用户操作日志

浪子不回头ぞ 提交于 2020-03-09 16:11:11

在Spring框架中,使用AOP配合自定义注解可以方便的实现用户操作的监控。首先搭建一个基本的Spring Boot Web环境开启Spring Boot,然后

引入必要依赖:

 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>

        <!-- aop依赖 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>

        <!-- mysql驱动 -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.41</version>
        </dependency>

        <!-- druid数据源驱动 -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.10</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

自定义注解

定义一个方法级别的@Log注解,用于标注需要监控的方法:

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Log {
    String value() default "";
}

创建库表和实体

在数据库中创建一张sys_log表,用于保存用户的操作日志

 

 

 

 实体:

public class SysLog implements Serializable {

    private Integer id;
    private String username;
    private String operation;
    private Integer time;
    private String method;
    private String params;
    private String ip;
    private Date createTime;

............

dao:

public interface SysLogDao {
    void saveSysLog(SysLog syslog);
}
@Repository
public class SysLogDaoImpl implements SysLogDao {

    @Autowired
    private JdbcTemplate jdbcTemplate;

    @Override
    public void saveSysLog(SysLog syslog) {

        System.out.println(syslog);

        StringBuffer sql = new StringBuffer("insert into sys_log ");
        sql.append("(id,username,operation,time,method,params,ip,create_time) ");
        sql.append("values(NULL,?,?,?,?,?,?,?)");
        String sql2=sql.toString();
        jdbcTemplate.update(sql2,syslog.getUsername(),syslog.getOperation(),syslog.getTime(),syslog.getMethod(),syslog.getParams(),syslog.getIp(),syslog.getCreateTime());
        jdbcTemplate.update(sql2);

    }
}

Aspect:

@Aspect
@Component
public class LogAspect {

    @Autowired
    private SysLogDao sysLogDao;

    @Pointcut("@annotation(com.lc.aop.annotation.Log)")
    public void pointcut() { }

    @Around("pointcut()")
    public Object around(ProceedingJoinPoint point) {
        Object result = null;
        long beginTime = System.currentTimeMillis();
        try {
            // 执行方法
            result = point.proceed();
        } catch (Throwable e) {
            e.printStackTrace();
        }
        // 执行时长(毫秒)
        long time = System.currentTimeMillis() - beginTime;
        // 保存日志
        saveLog(point, time);
        return result;
    }

    private void saveLog(ProceedingJoinPoint joinPoint, long time) {
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        Method method = signature.getMethod();
        SysLog sysLog = new SysLog();
        Log logAnnotation = method.getAnnotation(Log.class);
        if (logAnnotation != null) {
            // 注解上的描述
            sysLog.setOperation(logAnnotation.value());
        }
        // 请求的方法名
        String className = joinPoint.getTarget().getClass().getName();
        String methodName = signature.getName();
        sysLog.setMethod(className + "." + methodName + "()");
        // 请求的方法参数值
        Object[] args = joinPoint.getArgs();
        // 请求的方法参数名称
        LocalVariableTableParameterNameDiscoverer u = new LocalVariableTableParameterNameDiscoverer();
        String[] paramNames = u.getParameterNames(method);
        if (args != null && paramNames != null) {
            String params = "";
            for (int i = 0; i < args.length; i++) {
                params += "  " + paramNames[i] + ": " + args[i];
            }
            sysLog.setParams(params);
        }
        // 获取request
        HttpServletRequest request = HttpContextUtils.getHttpServletRequest();
        // 设置IP地址
        sysLog.setIp(IPUtils.getIpAddr(request));
        // 模拟一个用户名
        sysLog.setUsername("mrbird");
        sysLog.setTime((int) time);
        sysLog.setCreateTime(new Date());
        // 保存系统日志
        sysLogDao.saveSysLog(sysLog);
    }
}

controller:

@RestController
public class TestController {

    @Log("执行方法一")
    @GetMapping("/one")
    public void methodOne(String name) { }

    @Log("执行方法二")
    @GetMapping("/two")
    public void methodTwo() throws InterruptedException {
        Thread.sleep(2000);
    }

    @Log("执行方法三")
    @GetMapping("/three")
    public void methodThree(String name, String age) { }
}

工具类:

public class IPUtils {
    /**
     * 获取IP地址
     *
     * 使用Nginx等反向代理软件, 则不能通过request.getRemoteAddr()获取IP地址
     * 如果使用了多级反向代理的话,X-Forwarded-For的值并不止一个,而是一串IP地址,X-Forwarded-For中第一个非unknown的有效IP字符串,则为真实IP地址
     */
    public static String getIpAddr(HttpServletRequest request) {

        String ip = request.getHeader("x-forwarded-for");
        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.getRemoteAddr();
        }
        return "0:0:0:0:0:0:0:1".equals(ip) ? "127.0.0.1" : ip;
    }
}

 

public class HttpContextUtils {
    public static HttpServletRequest getHttpServletRequest() {
        return ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
    }
}
