AopLog

AopLog是基于SpringAop和ThreadLocal实现的一个对请求方法埋点信息收集与处理的日志工具包。

设计目的和场景 :

  • 使用Spring AOP拦截方法参数大部分做法基本上大同小异,不用每个项目工程都写AOP拦截处理日志的代码,引入此包即可。
  • 可获取埋点方法的请求参数,响应参数,请求头,以及内部耗时,方法是成功还是失败,自定义步骤记录等等信息。
  • 整个方法完整过程只产生一个埋点信息记录(一个LogData对象),比如@Controller中一次完整的http请求。
  • 收集情况可选,可只在异常时执行收集过程(有些只是为了排查问题打印的日志,程序正常运行时其实毫无意义)。
  • 埋点信息收集,自行实现收集过程,比如埋点日志打印,常见埋点日志写入数据库,写入到文件,写入队列等等。
  • 埋点信息收集不干扰埋点方法正常流程,收集过程异步化处理(默认,可通过注解的asyncMode进行设置),不影响正常请求方法的性能与响应。
  • 只需通过@AopLog注解(或者自定义切面)决定是否埋点收集。

快速开始

项目通过Maven仓库地址 的pom.xml引入。


<dependency>
    <groupId>com.github.ealenxie</groupId>
    <artifactId>aop-log</artifactId>
    <version>2.5</version>
</dependency>

或者通过gradle引入

compile group: 'com.github.ealenxie', name: 'aop-log', version: '2.5'

@AopLog注解使用,进行埋点收集

直接在类(作用类的所有方法)或类方法(作用于方法)上加上注解@AopLog,进行埋点收集

例如 :


@AopLog(type = "测试接口", stackTraceOnErr = true)
@RestController
public class AppController {

    @GetMapping("/app/sayHello")
    public RespBody<String> sayHello() {
        return RespBody.ok("hello EalenXie");
    }

}

自定义全局的日志收集器实现收集 LogCollector

例如只是简单打印,或写入到库等等。(例子只是提供参考说明,收集过程请不要完全照搬,没有考虑到LogData不能被序列化的情况)


import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.github.LogData;
import com.github.collector.LogCollector;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Component;

/**
 * @author EalenXie create on 2020/9/15 13:46
 * 此为样例参考
 * 配置一个简单的日志收集器 这里只是做了一个log.info打印一下,可以在这里写入到数据库中或者写入
 */
@Slf4j
@Component
public class AopLogCollector implements LogCollector {
    private ObjectMapper objectMapper = new ObjectMapper();

    @Override
    public void collect(LogData logData) {
        try {
            log.info(objectMapper.writeValueAsString(logData));
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }
    }
}

配置@Component的全局日志收集器只能配置一个。

接口调用 /say/hello 测试即可看看到控制台打印出结果 :

2020-09-16 16:01:04.782  INFO 2012 --- [AsyncExecutor-2] name.ealen.infra.advice.AopLogCollector  : {"appName":"app-template","host":"127.0.0.1","port":8080,"clientIp":"192.168.110.1","reqUrl":"http://localhost:8080/app/sayHello","httpMethod":"GET","headers":{"User-Agent":"Apache-HttpClient/4.5.10 (Java/11.0.5)"},"type":"测试","content":"","method":"name.ealen.api.facade.AppController#sayHello","args":null,"respBody":{"code":"200","desc":"OK","message":"请求成功","dateTime":"2020-09-16 16:01:04","body":"hello EalenXie"},"logDate":1600243264780,"costTime":1,"threadName":"http-nio-8080-exec-3","threadId":33,"success":true}

埋点日志对象LogData属性说明

LogData 埋点日志对象获取的内容

字段 类型 注释
appName String 应用名称
host String 主机
port int 端口号
clientIp String 请求客户端的Ip
reqUrl String 请求地址
headers Object 请求头部信息(可选择获取) 默认获取user-agent,content-type
tag String 操作标签,默认值undefined
content String 方法步骤内容,默认是空,可使用LogData.step进行内容步骤记录
method String 请求的本地java方法
args Object 方法请求参数
respBody Object 方法响应参数
costTime long 整个方法内部耗时
logDate Date Log产生时间,LogData对象初始化的时间
threadName String 线程名称
threadId long 线程Id
success boolean 执行状态,成功(true)/异常(false)

AopLog 注解选项说明

选项 类型 说明 默认
logOnErr boolean 仅当发生异常时才收集 false
tag String 操作标签 默认值"undefined"
headers String[] 获取的header信息 ,选择要获取哪些header信息 默认"User-Agent","content-type"
args boolean 是否获取请求参数 true
respBody boolean 是否获取响应参数 true
stackTraceOnErr boolean 当目标方法发生异常时,是否追加异常堆栈信息到LogData的content中 false
asyncMode boolean 异步方式收集 true
collector Class<? extends LogCollector> 指定日志收集器 默认不调整收集器,使用全局的日志收集器

LogData的step方法。

记录步骤。(如果某些重要步骤希望被记录下来) 例如 :


import com.github.AopLog;
import com.github.LogData;
import name.ealen.infra.base.resp.RespBody;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;


/**
 * @author EalenXie create on 2020/6/22 14:28
 */
@AopLog(tag = "测试", stackTraceOnErr = true)
@RestController
public class AppController {


    @GetMapping("/app/sayHello")
    public RespBody<String> sayHello() {
        LogData.step("1. 第一步执行完成");
        //......
        LogData.step("2. 第二步执行完成");
        //.....
        LogData.step("3. service的方法执行完成");
        //.....
        return RespBody.ok("hello EalenXie");
    }

}

此时再次接口调用 /say/hello 测试即可看看到控制台打印出结果,重点观察content字段 :

2020-09-16 17:26:20.285  INFO 3284 --- [AsyncExecutor-2] name.ealen.infra.advice.AopLogCollector  : {"appName":"app-template","host":"127.0.0.1","port":8080,"clientIp":"192.168.110.1","reqUrl":"http://localhost:8080/app/sayHello","httpMethod":"GET","headers":{"User-Agent":"Apache-HttpClient/4.5.10 (Java/11.0.5)"},"tag":"测试","content":"1. 第一步执行完成\n2. 第二步执行完成\n3. service的方法执行完成\n","method":"name.ealen.api.facade.AppController#sayHello","args":null,"respBody":{"code":"200","desc":"OK","message":"请求成功","dateTime":"2020-09-16 17:26:20","body":"hello EalenXie"},"logDate":1600248380283,"costTime":1,"threadName":"http-nio-8080-exec-2","threadId":32,"success":true}
"content":"1. 第一步执行完成\n2. 第二步执行完成\n3. service的方法执行完成\n"

不通过@AopLog注解,通过自定义切面进行收集

自定义切面注入AopLogProcessor,调用proceed(config, point)即可



import com.github.AopLogConfig;
import com.github.AopLogProcessor;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;

/**
 * Created by EalenXie on 2021/7/14 10:29
 * 自定义切面
 */
@Aspect
@Component
public class CustomLogDataAspect {

    @Resource
    private AopLogProcessor aopLogProcessor;
    private static final AopLogConfig CONFIG;

    static {
        CONFIG = new AopLogConfig();
        CONFIG.setTag("操作标签");
        CONFIG.setStackTraceOnErr(false);
        CONFIG.setHeaders(new String[]{"content-type", "user-agent"});
    }

    // 自定义切点 execution(public * com.test.web.TestController.*(..))
    @Pointcut("execution(public * com.test.web.TestController.*(..))")
    public void test() {
        //ig
    }

    // 请使用环绕通知 @Around()
    @Around("test()")
    public Object note(ProceedingJoinPoint point) throws Throwable {
        return aopLogProcessor.proceed(CONFIG, point);
    }
}
