錯誤，由先前經驗知道，是重複引入serlet-api.jar所致，經檢視effictive pom沒有找到相關操作，搜尋工程路徑，確實存在該包，
然後利用pom dependencies檢視依賴關係
知道是commos-loggings:commons-logging:1.1引入。
檢視activemq-parent.pom，存在
<dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>${commons-logging-version}</version> <exclusions> <exclusion> <groupId>avalon-framework</groupId> <artifactId>avalon-framework</artifactId> </exclusion> <exclusion> <groupId>logkit</groupId> <artifactId>logkit</artifactId> </exclusion> <exclusion> <groupId>log4j</groupId> <artifactId>log4j</artifactId> </exclusion> <exclusion> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> </exclusion> </exclusions> </dependency>
將該段程式碼拷貝至工程內，問題解決
