springboot整合AOP实现记录日志功能

springboot整合AOP实现记录日志功能

一、导入pom包

		
            com.alibaba
            druid-spring-boot-starter
            1.1.14
        
        
            org.springframework.boot
            spring-boot-starter-jdbc
        
        
        
            org.springframework.boot
            spring-boot-starter-aop
        
        
            mysql
            mysql-connector-java
            5.1.46
        

二、自定义注解

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

三、建表

CREATE TABLE `sys_log` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(255) DEFAULT NULL,
  `operation` varchar(255) DEFAULT NULL,
  `time` decimal(13,0) DEFAULT NULL,
  `method` varchar(255) DEFAULT NULL,
  `params` varchar(255) DEFAULT NULL,
  `ip` varchar(255) DEFAULT NULL,
  `create_time` datetime DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=28 DEFAULT CHARSET=utf8;

四、创建实体类

@Data
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;
}

五、dao层、service层、controller层代码

public interface SysLogDao {
    void saveSysLog(SysLog syslog);
}

@Service
public class SysLogDaoImp implements SysLogDao {

    @Autowired
    private JdbcTemplate jdbcTemplate;

    @Override
    public void saveSysLog(SysLog syslog) {
        StringBuffer sql = new StringBuffer("insert into sys_log VALUES (NULL,?,?,?,?,?,?,?)");
        String sql2=sql.toString();
        jdbcTemplate.update(sql2,syslog.getUsername(),syslog.getOperation(),syslog.getTime(),syslog.getMethod(),syslog.getParams(),syslog.getIp(),syslog.getCreateTime());
    }
}

@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){}
}

六、需要的工具类

public class IpUtils
{
    public static String getIpAddr(HttpServletRequest request)
    {
        if (request == null)
        {
            return "unknown";
        }
        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("X-Forwarded-For");
        }
        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("X-Real-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) Objects.requireNonNull(RequestContextHolder.getRequestAttributes())).getRequest();
    }
}

七、创建切面和切点

@Aspect
@Component
public class LogAspect {
    @Autowired
    private SysLogDao sysLogDao;

    @Pointcut("@annotation(com.example.springbootdemo.utils.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);
    }
}
