log4j日誌級別失控問題

當我們在配置文件中指定一些控制時：

我們可以指定哪些模塊下的類進行怎樣格式規則的輸出，是不是聽起來很彆扭，見如下配置, 我們用相應<logger>標籤來指定相應<appender>模塊的日誌規則,<appender>標籤裏面的filter是用來控制日誌輸出的最低與最高級別，<root>標籤頁可以統一配置一些<appender>模塊的日誌輸出級別，但是優先級沒有其中filter高，見下：

注意：我們可能在filter裏面設置了日誌的輸出級別，並且本地測試沒問題，但是發佈上線後卻不起作用，那是應爲項目啓動時類加載順序的問題，我們的web.xml中log與spring容器的加載順序應該換一下位置，解決方法如下

1、將下面位置調換位置（應該是log.xml先加載，spring後加載）

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpsdfath:spring-config.xml</param-value>
</context-param>

<context-param>    
    <param-name>log4jConfigLocation</param-name>    
    <param-value>classpath:log4j.xml</param-value>    
</context-param>

2、將下面配置調換位置

<context-param>  
    <param-name>logbackConfigLocation</param-name>  
    <param-value>/WEB-INF/conf/logback.xml</param-value>  
</context-param>

<listener>  
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
</listener>     
  
<listener>  
<listener-class>ch.qos.logback.ext.spring.web.LogbackConfigListener</listener-class>  
</listener>
