【JavaWeb下】SLF4J+LogBack使用配置需要的Jar包logback.xml配置檔案Java代碼測試輸出結果

關于SLF4j和LogBack的相關說明請自行百度

由于換工作原因，現在公司項目是普通JavaWeb項目（JSP那種）,而且日志系統是公司自己寫的，每次遇到問題，都不能抛出詳細的報錯資訊，導緻修改線上問題的時候會費很多時間（可能對于新到公司來說吧，老手還好），無奈隻能自己在本地先測試咯，使用了之前的日志架構

SLF4j+LofBack

 來重寫日志輸出~~~最後感覺還可以，直接開始~

需要的Jar包

由于沒有用到Maven,所有的Jar包都需自己下載下傳（莫法~），還好隻用到了以下3個Jar包…
  1. logback-classic-1.2.3.jar
  2. logback-core-1.2.3.jar
  3. slf4j-api-1.7.9.jar
下載下傳之後放到

WEB-INF/lib

 目錄下,如下圖所示
【JavaWeb下】SLF4J+LogBack使用配置需要的Jar包logback.xml配置檔案Java代碼測試輸出結果

logback.xml配置檔案

這個檔案主要是用來配置日志輸出及相關政策的，我這裡呢根據自己的需要大部分已經配置好了，各位如果覺得有需要改進的地方可以給我說喲~

logback.xml配置檔案放到classpath路徑下

此配置檔案的效果為：按天生成日志檔案，每個日志檔案的大小為

10KB

 （可通過設定

maxFileSize

 屬性來改變單個日志檔案大小），日志檔案按天存放，最大保留30天（可通過設定

maxHistory

 屬性來設定儲存時長）

Java代碼測試

建立

test.java

 
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class test{
    private static Logger log = LoggerFactory.getLogger(test.class);
    public void LogTest() {
        log.info("Info查詢醫院科室");
        log.debug("Debug查詢醫院科室");
        log.warn("Warn查詢醫院科室");
        String a = null;
        try {
            if(a.length()==1) {
                System.out.println("1");
            }
        } catch (Exception e) {
            log.error("查詢醫院科室出錯:{}",e.getMessage(),e);
        }
    }
}

輸出結果

進入上述方法之後，會在我們定義的日志目錄中輸出

*-debug.log,*-error.log,*-info.log,*-warn.log

的日志檔案（如圖①所示）

當我們的單個日志檔案超過

10KB

 ,會自動生成日志檔案夾，并按照我們定義的格式分段儲存當天日志（如圖②③所示）

有些同學可能會問，我們不是設定的日志格式大小為10KB麼？為什麼會出現14KB,11KB的情況？

我們打開圖③的

可以看到我們的錯誤日志報錯是完整的報錯資訊，那我們是不是可以認為超出我們定義的日志大小，是因為logback為我們做了

優化

 呢？哈哈，反正不管怎樣都在我們接受範圍内、好了，關于slf4j+logback的使用基本就這樣啦。

如果有什麼問題或者建議，請在評論區留言哦

 ，謝謝
