首先存入和管理日志有elk,但是项目管理系统作为不是很大型的项目，就不想引入太多的组件

这样管理起来也很麻烦，于是就想着在已引入的mongodb上存储

1.自定义一个appender

public class LogbackToMongoAppender extends AppenderBase<LoggingEvent>{
	
//	@Autowired
//	private MongoTemplate mongoTemplate;
	@Override
	protected void append(LoggingEvent eventObject) {
		MongoTemplate mongoTemplate = BeanHelper.getBean(MongoTemplate.class);
		Logback logback=new Logback();
		logback.setTimeStamp(eventObject.getTimeStamp());
		logback.setCreateTime(DateHelper.DateToString(new Date(eventObject.getTimeStamp()), DateStyle.YYYY_MM_DD_HH_MM_SS.getValue()));
		logback.setContent(eventObject.toString());
		logback.setLevel(eventObject.getLevel().levelStr);
		logback.setLoggerName(eventObject.getLoggerName());
		logback.setThreadName(eventObject.getThreadName());
		mongoTemplate.save(logback);
	}

}

2.所使用的实体类

import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection = "logback")
public class Logback {
	private String createTime; 
	private String content; 
	private String level;
	private long timeStamp;
	private String loggerName;
	private String threadName;
	public String getCreateTime() {
		return createTime;
	}
	public void setCreateTime(String createTime) {
		this.createTime = createTime;
	}
	public String getContent() {
		return content;
	}
	public void setContent(String content) {
		this.content = content;
	}
	public String getLevel() {
		return level;
	}
	public void setLevel(String level) {
		this.level = level;
	}
	public long getTimeStamp() {
		return timeStamp;
	}
	public void setTimeStamp(long timeStamp) {
		this.timeStamp = timeStamp;
	}
	public String getLoggerName() {
		return loggerName;
	}
	public void setLoggerName(String loggerName) {
		this.loggerName = loggerName;
	}
	public String getThreadName() {
		return threadName;
	}
	public void setThreadName(String threadName) {
		this.threadName = threadName;
	}
	
}

3.在logback xml文件中配置 新加一个appender标签(xx部分填定自已的包名)

 <appender name="MyAppender" class="com.xx.log.LogbackToMongoAppender" />

在root里面加入定义的appender

<root level="debug">
        <appender-ref ref="CONSOLE" />
        <appender-ref ref="DEBUG_FILE" />
        <appender-ref ref="INFO_FILE" />
        <appender-ref ref="WARN_FILE" />
        <appender-ref ref="ERROR_FILE" />
         <appender-ref ref="MyAppender" /> <!--这里是上面定义的appender-->
    </root>
