1. 在数据库中创一个新的表

 因为须要存入数据库,所以依据你的理论业务创立这个表,我没弄多大,因为保留不到几天就会删掉。表名称和字段都随你意:
    表名称:biz_monitor_time 
    id int 5 不是 null 主键自增
    request_address varchar 50 不是 null 申请地址
    waste_time int 5 不是 null 消耗工夫
    create_time datetime 默认值 now() 不是 null 创立工夫

2. 依据创立的表生成代码

 就是那几个层:mapper、service、serviceImpl、controller
你能够用代码生成器主动生成,当然你也能够手撸,如果你既不想手撸也没有生成器,我把代码会贴在上面,供你参考:

domain :

package com.cema.manage.project.manage.monitorTime.domain;

/**
 * 统计 http 申请响应时间表 biz_monitor_time
 *
 * @author reasahi
 * @date 2021-04-27
 */
@TableName(value = "biz_monitor_time")
public class MonitorTime extends Model<MonitorTime> {
    private static final long serialVersionUID = 1L;

    /**
     * 主键
     */
    @TableId(value = "id")
    private Integer id;
    /**
     * 申请地址
     */
    @TableField(value = "request_address")
    private String requestAddress;
    /**
     * 消耗工夫
     */
    @TableField(value = "waste_time")
    private Integer wasteTime;
    /**
     * 创立工夫
     */
    @TableField(value = "create_time")
    private Date createTime;

    /**
     * 设置:主键
     */
    public void setId(Integer id) {this.id = id;}

    /**
     * 获取:主键
     */
    public Integer getId() {return id;}

    /**
     * 设置:申请地址
     */
    public void setRequestAddress(String requestAddress) {if (requestAddress != null) {if (requestAddress.trim().isEmpty()) {this.requestAddress = null;} else {this.requestAddress = requestAddress;}
        }
    }

    /**
     * 获取:申请地址
     */
    public String getRequestAddress() {return requestAddress;}

    /**
     * 设置:消耗工夫
     */
    public void setWasteTime(Integer wasteTime) {this.wasteTime = wasteTime;}

    /**
     * 获取:消耗工夫
     */
    public Integer getWasteTime() {return wasteTime;}

    /**
     * 设置:创立工夫
     */
    public void setCreateTime(Date createTime) {this.createTime = createTime;}

    /**
     * 获取:创立工夫
     */
    public Date getCreateTime() {return createTime;}

    @Override
    protected Serializable pkVal() {return this.id;}
}

mapper :

package com.cema.manage.project.manage.monitorTime.mapper;

/**
 * 统计 http 申请响应工夫 数据层
 * 
 * @author reasahi
 * @date 2021-04-27
 */
public interface MonitorTimeMapper  extends BaseMapper<MonitorTime>
{void insertMonitorTime(MonitorTime monitorTime);

}

xml :

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.cema.manage.project.manage.monitorTime.mapper.MonitorTimeMapper">

    <!--  biz_monitor_time  -->
    <resultMap id="resultMapMonitorTime" type="com.cema.manage.project.manage.monitorTime.domain.MonitorTime">
        <id column="id" property="id"></id>
        <result column="request_address" property="requestAddress"></result>
        <result column="waste_time" property="wasteTime"></result>
        <result column="create_time" property="createTime"></result>
    </resultMap>

    <insert id="insertMonitorTime" parameterType="com.cema.manage.project.manage.monitorTime.domain.MonitorTime">
        INSERT INTO biz_monitor_time (request_address, waste_time)
        VALUES (#{requestAddress}, #{wasteTime});
    </insert>

</mapper>

service :

package com.cema.manage.project.manage.monitorTime.service;

/**
 * 统计 http 申请响应工夫 服务层
 * 
 * @author reasahi
 * @date 2021-04-27
 */
public interface IMonitorTimeService extends IService<MonitorTime>
{void insertMonitorTime(MonitorTime monitorTime);
    
}

serviceImpl :
阐明:
代码中的 @Async(“asyncServiceExecutor”) 为异步调用 外面的 asyncServiceExecutor 为本人创立的异步服务执行器的 bean 的名称,它实际上是一个线程池,我将它丢进去做异步解决,你能够本人撸一个,或者复制他人的,都没关系。如果你不喜爱手撸,那我会贴在上面,供你参考:

package com.cema.manage.project.manage.monitorTime.service;

/**
 * 统计 http 申请响应工夫 服务层实现
 *
 * @author reasahi
 * @date 2021-04-27
 */
@Service
public class MonitorTimeServiceImpl extends ServiceImpl<MonitorTimeMapper, MonitorTime> implements IMonitorTimeService {

    @Resource
    private MonitorTimeMapper monitorTimeMapper;

    @Override
    @Async("asyncServiceExecutor")
    public void insertMonitorTime(MonitorTime monitorTime) {monitorTimeMapper.insertMonitorTime(monitorTime);
    }

}

异步工作配置 :

package com.cema.manage.config;

@Configuration
@EnableAsync
public class AsyncTaskConfig  {@Bean(name = "asyncServiceExecutor")
    public Executor getAsyncExecutor() {ThreadPoolTaskExecutor threadPool = new VisiableThreadPoolTaskExecutor();
        // 设置外围线程数
        threadPool.setCorePoolSize(1000);
        // 设置最大线程数
        threadPool.setMaxPoolSize(1000000);
        // 线程池所应用的缓冲队列
        threadPool.setQueueCapacity(Integer.MAX_VALUE);
        // 期待工作在关机时实现 -- 表明期待所有线程执行完
        threadPool.setWaitForTasksToCompleteOnShutdown(true);
        // 等待时间(默认为 0,此时立刻进行),并没期待 xx 秒后强制进行
        threadPool.setAwaitTerminationSeconds(60);
        // 线程名称前缀
        threadPool.setThreadNamePrefix("Derry-Async-");
        // 初始化线程
        threadPool.initialize();
        return threadPool;
    }

}

controller : 无需变动。

3. 实现拦截器

阐明:通过构造方法给 iMonitorTimeService 赋值。

package com.cema.manage.config.Interceptor;

@Component
public class MonitoringTimeInterceptor implements HandlerInterceptor {

    private IMonitorTimeService iMonitorTimeService;

    public MonitoringTimeInterceptor(IMonitorTimeService iMonitorTimeService) {this.iMonitorTimeService = iMonitorTimeService;}

    @Override
    public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {long start = System.currentTimeMillis();
        httpServletRequest.setAttribute("start", start);
        return true;
    }

    @Override
    public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception {long start = (Long) httpServletRequest.getAttribute("start");
        long end = System.currentTimeMillis() - start;
        String uri = httpServletRequest.getRequestURI();
        MonitorTime monitorTime = new MonitorTime();
        monitorTime.setRequestAddress(uri);
        monitorTime.setWasteTime((int) end);
        iMonitorTimeService.insertMonitorTime(monitorTime);
    }

    @Override
    public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception {}}

4. 继承 WebMvc 配置适配器来增加你的拦截器,让它工作

阐明:
registry.addInterceptor(这里就是你刚刚写好的拦截器,咱们通过构造函数赋值)。addPathPatterns(这外面填写你须要拦挡的 url,去看看你的 controller 层,如:”/pfs/**”)。

package com.cema.manage.config;

@Configuration
public class ViewConfigure extends WebMvcConfigurerAdapter {

    @Resource
    private IMonitorTimeService iMonitorTimeService;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {// .addPathPatterns("/**") // 拦挡所有申请 /upload/ecology
        registry.addInterceptor(new MonitoringTimeInterceptor(iMonitorTimeService))
                .addPathPatterns("/token/**")
        ;
    }
}

5. 总结

代码局部就完结了,当前进了你拦截器的 http 申请都会被存入到数据库,如下图:

你能够依据各接口响应时长来判断是否须要优化。你能够在数据库中应用一些聚合函数来看看最大响应时长的接口,或者某个接口的均匀响应工夫等。当然,这只是非常简单的拦截器以及数据的存入,你齐全能够撸一个更好哒。
