在我的應用程序，我使用SLF4J與存在SLF4J解決多個綁定
- SLF4J-簡單1.6.2.jar多個綁定登錄門面
- 的logback經典-1.0.4。 JAR
這兩種在pom.xml中被定義爲
**<!--MANDATORY -->**
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.6.2</version>
</dependency>
**<!--SIMPLY DUMPS THE MESSAGE TO ERROR STREAM -->**
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.6.2</version>
</dependency>
**<!--logback : further configuration in logback.xml -->**
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-core</artifactId>
<version>1.0.4</version>
</dependency>
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.0.4</version>
</dependency>
一個簡單的測試程序，該程序可以被本地運行
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class TimePass {
private Logger log = LoggerFactory.getLogger(getClass());
public static void main(String[] args) {
new TimePass().run();
}
private void run() {
System.out.println(log);
log.info("WE ARE RUNNING");
System.out.println("HIHIHIHI");
}
}
該項目/ webapp部署在2個位置。 但是，當我在兩者上運行它時，結果都顯着不同。
On 1 instance, output is

這個問題似乎是在這兩種情況下，多個綁定被徵了，但在不同的順序。
**在情況1中：在那裏記錄： 1. SLF4J-簡單1.6.2.jar 2.的logback-經典1.0.4.jar 它所用第一結合登錄
在案例2中：它沒有登錄，訂單相反，因此它尋找logback.xml並且無法解析webcontainer特定變量（$ {catalina.home}）**
我不知道這種逆轉的原因。
我需要這兩個綁定。在我本身運行java文件的情況下，我希望slf4j-簡單綁定在logback綁定之前。
在此先感謝。
