Springboot打印接口耗时
Springboot 打印 接口 耗时
三种方式 下面为大家一一对应
1 aop切面的方式
1.1 实现思路
- 引入aop依赖
- 自定义注解
- 定义切面,采用环绕通知
1.2 代码实现
1)引入依赖
<!--aop-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
2)自定义注解LogAnnotation
/**
* 日志注解
* METHOD 方法上 type 类上
*/
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface LogAnnotation {
/**
* 模块
*/
String module() default "";
/**
* 简单描述接口的作用
*/
String operation() default "";
}
3)定义切面
简单分析一下切面实现的功能:
/**
* @author : look-word
* 2022-07-27 16:03
**/
@Slf4j
@Aspect
@Component
public class LogAspect {
/**
* 切入点
*/
@Pointcut("@annotation(look.word.reggie.common.aop.LogAnnotation)")
public void logPointCut() {
}
/**
* 环绕通知
*
* @param point 连接点
*/
@Around("logPointCut()")
public Object around(ProceedingJoinPoint point) throws Throwable {
long beginTime = System.currentTimeMillis();
//执行方法
Object result = point.proceed();
//执行时长(毫秒)
long time = System.currentTimeMillis() - beginTime;
//保存日志
recordLog(point, time);
return result;
}
private void recordLog(ProceedingJoinPoint joinPoint, long time) {
MethodSignature signature = (MethodSignature) joinPoint.getSignature();
// 获取当前方法
Method method = signature.getMethod();
LogAnnotation logAnnotation = method.getAnnotation(LogAnnotation.class);
log.info("=====================log start================================");
log.info("module:{}", logAnnotation.module());
log.info("operation:{}", logAnnotation.operation());
//请求的方法名
String className = joinPoint.getTarget().getClass().getName();
String methodName = signature.getName();
log.info("request method:{}", className + "." + methodName + "()");
//请求的参数
Object[] args = joinPoint.getArgs();
Stream<?> stream = ArrayUtils.isEmpty(args) ? Stream.empty() : Arrays.stream(args);
List<Object> logArgs =
stream.filter(arg -> (!(arg instanceof HttpServletRequest) && !(arg instanceof HttpServletResponse))).collect(Collectors.toList());
String params = JSON.toJSONString(logArgs);
log.info("params:{}", params);
//获取request 设置IP地址
HttpServletRequest request = HttpContextUtils.getHttpServletRequest();
log.info("ip:{}", IpUtils.getIpAddr(request));
log.info("execute time : {} ms", time);
log.info("=====================log end================================");
}
}
1.3 功能测试
在接口上添加注解即可,还有描述信息
2 过滤器的方式
这种方式简单点 但是可配置性不高
注意:一定得扫描到spring容器中
创建一个类 实现 filter接口
- init:该方法是对filter对象进行初始化的方法,仅在容器初始化filter对象结束后被调用一次,参数FilterConfig可以获得filter的初始化参数;
- doFilter:可以对request和response进行
<u>预处理</u>
。其中FilterChain可以将处理后的
request和response对象传递到过滤链上的下一个资源。- destroy():该方法在容器销毁对象前被调用。
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
@Component
public class LogFilter implements Filter {
private static final Logger LOG = LoggerFactory.getLogger(LogFilter.class);
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
// 打印请求信息
HttpServletRequest request = (HttpServletRequest) servletRequest;
LOG.info("------------- LogFilter 开始 -------------");
LOG.info("请求地址: {} {}", request.getRequestURL().toString(), request.getMethod());
LOG.info("远程地址: {}", request.getRemoteAddr());
long startTime = System.currentTimeMillis();
filterChain.doFilter(servletRequest, servletResponse);
LOG.info("------------- LogFilter 结束 耗时:{} ms -------------", System.currentTimeMillis() - startTime);
}
}
结果
总结
1.过滤器用来实现通用的功能,减少代码冗余,提高可维护性;
2.一个过滤器可以配置给多个资源使用(编码过滤器);
3.一个资源也可以配置多个过滤器,按照配置顺序调用。
3 拦截器的方式
如果不懂 请先看了 介绍再来
话不说多 直接上代码
创建拦截器
/**
* 拦截器:Spring框架特有的,常用于登录校验,权限校验,请求日志打印 /login
* @author : look-word
* 2022-06-26 13:55
**/
@Component
public class LogInterceptor implements HandlerInterceptor {
private static final Logger LOG = LoggerFactory.getLogger(LogInterceptor.class);
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
// 打印请求信息
LOG.info("------------- LogInterceptor 开始 -------------");
LOG.info("请求地址: {} {}", request.getRequestURL().toString(), request.getMethod());
LOG.info("远程地址: {}", request.getRemoteAddr());
long startTime = System.currentTimeMillis();
request.setAttribute("requestStartTime", startTime);
return true;
}
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
long startTime = (Long) request.getAttribute("requestStartTime");
LOG.info("------------- LogInterceptor 结束 耗时:{} ms -------------", System.currentTimeMillis() - startTime);
}
}
注册拦截器
把我们的拦截器 注册到 拦截器链中
/**
* @author : look-word
* 2022-06-26 14:03
**/
@Configuration
public class SpringMvcConfig implements WebMvcConfigurer {
@Resource
private LogInterceptor logInterceptor;
/**
* 注册拦截器
* @param registry
*/
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry
.addInterceptor(logInterceptor)
.addPathPatterns("/**")// 对那些接口拦截
.excludePathPatterns("/login");// 对哪些接机口放行
WebMvcConfigurer.super.addInterceptors(registry);
}
}
测试结果
