SpringBoot集成MongoDB用于进行日志管理

并不是什么高深的技术,主要是配置,配完了万事好说。
 
至于MongoDB的使用这里就不多说了。看看我什么时候心血来潮想整理一下再整理一份文章出来。
 
最基本的pom.xml配置和yml配置。无需多说

		<!--MongoDB-->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-data-mongodb</artifactId>
		</dependency>
		<!--logback日志框架-->
		<dependency>
			<groupId>ch.qos.logback</groupId>
			<artifactId>logback-core</artifactId>
			<version>1.2.3</version>
		</dependency>
		<dependency>
			<groupId>ch.qos.logback</groupId>
			<artifactId>logback-classic</artifactId>
			<version>1.2.3</version>
		</dependency>

由于要使用到logback,所以还需要一个logback.xml配置文件,此文件存放于resources目录下

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
<!--logback使用的日志输出文件-->
<configuration scan="true" scanPeriod="3600 seconds" debug="false">
  <property name="logDir" value="logs"/>
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <charset>UTF-8</charset>
      <pattern>%d [%thread] %-5level %logger{68} %line - logId[[%X{client}][%X{request_id}]] - %msg%n</pattern>
    </encoder>
  </appender>
  <appender name="RollingFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
      <level>TRACE</level>
    </filter>
    <!-- 可让每天产生一个日志文件,最多 10 个,自动回滚 -->
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
      <fileNamePattern>${logDir}/file-%d{yyyy-MM-dd}.log</fileNamePattern>
      <maxHistory>10</maxHistory>
    </rollingPolicy>
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger - %msg%n</pattern>
      <charset>UTF-8</charset>
    </encoder>
  </appender>
  <appender name="MONGODB" class="top.yibobo.hospital.logback.MongoDBAppender"/>
  <root level="INFO">
    <appender-ref ref="STDOUT"/>
    <appender-ref ref="RollingFile"/>
    <appender-ref ref="MONGODB"/>
  </root>
</configuration>

 
至此,配置文件书写完毕。轮到重要的具体实现了。
首先定义一个接口,继承MongoRepository

package top.yibobo.hospital.logback;
import org.springframework.data.mongodb.repository.MongoRepository;
public interface LogRepository extends MongoRepository<MyLog,String> {
}

 
这是日志信息的实体类,可以自己定义

package top.yibobo.hospital.logback;
import java.io.Serializable;
import java.util.Date;
public class MyLog implements Serializable{
    private String id;
    private String level;
    private String message;
    private String thread;
    private Date ts;
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getLevel() {
        return level;
    }
    public void setLevel(String level) {
        this.level = level;
    }
    public String getMessage() {
        return message;
    }
    public void setMessage(String message) {
        this.message = message;
    }
    public String getThread() {
        return thread;
    }
    public void setThread(String thread) {
        this.thread = thread;
    }
    public Date getTs() {
        return ts;
    }
    public void setTs(Date ts) {
        this.ts = ts;
    }
}

 
这是将日志信息输出到MongoDB的实现类

package top.yibobo.hospital.logback;
import ch.qos.logback.classic.spi.LoggingEvent;
import ch.qos.logback.core.UnsynchronizedAppenderBase;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;
import java.util.Date;
/*
   将日志信息输出到mongdb的实现类
 */
@Component
public class MongoDBAppender extends UnsynchronizedAppenderBase<LoggingEvent>
implements ApplicationContextAware{
    private static LogRepository logRepository;
    @Override
    protected void append(LoggingEvent loggingEvent) {
        MyLog myLog = new MyLog();
        myLog.setLevel(loggingEvent.getLevel().toString());
        myLog.setMessage(loggingEvent.getFormattedMessage());
        myLog.setThread(loggingEvent.getThreadName());
        myLog.setTs(new Date());
        logRepository.save(myLog);
    }
    @Override
    public void start() {
        super.start();
    }
    @Override
    public void stop() {
        super.stop();
    }
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        if (applicationContext.getAutowireCapableBeanFactory()
                .getBean(LogRepository.class)!=null){
            logRepository = applicationContext
                    .getAutowireCapableBeanFactory().getBean(LogRepository.class);
        }
    }
}

 
 
这是日志切面

package top.yibobo.hospital.logback;
import com.mongodb.BasicDBObject;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
import javax.servlet.http.HttpServletRequest;
import java.util.Arrays;
import java.util.Enumeration;
import java.util.HashMap;
import java.util.Map;
@Aspect
@Component
@Order(3)//Order用来定义切面执行顺序
public class WebLogAspect {
    //定义日志记录器
    private Logger logger = LoggerFactory.getLogger("MONGODB");
    @Pointcut("execution(public  * top.yibobo.hospital.controller.*.*(..))")
    public void weblog(){}
    @Before("weblog()")
    public void dobefore(JoinPoint joinPoint){
        //由于切面类不能从方法入参注入、所以只能这样获取servlet请求对象
        ServletRequestAttributes attributes = (ServletRequestAttributes)
                RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        //mongodb保存的基本对象(文档)
        BasicDBObject object = getBasicDBObject(request,joinPoint);
        logger.info(object.toString());
    }
    private BasicDBObject getBasicDBObject(HttpServletRequest request,JoinPoint joinPoint){
        BasicDBObject b = new BasicDBObject();
        b.append("RequestURL:",request.getRequestURI().toString());
        b.append("METHOD",request.getMethod());
        b.append("RemoteAddr",request.getRemoteAddr());
        b.append("HEADER",getHeader(request));
        //b.append("CLASS_METHOD",joinPoint.getSignature().getDeclaringTypeName()+"."+joinPoint.getSignat);
        b.append("Args",Arrays.toString(joinPoint.getArgs()));
        return b;
    }
    private Map<String,String> getHeader(HttpServletRequest request){
        Map<String,String> map  = new HashMap<>();
        Enumeration<String> header = request.getHeaderNames();
        while (header.hasMoreElements()){
            String key = header.nextElement();
            map.put(key,request.getHeader(key));
        }
        return map;
    }
}
