maven專案生成的war包在tomcat下執行報錯

MavenTomcat



maven專案在tomcat中執行 主要會有兩種錯誤:

一是依賴包衝突

二是slf4j包錯誤


如下:

我們來分析原因和嘗試解決:

依賴包衝突

原因

在Maven1中，需要把依賴所需要的包每個列出。這對於使用類似如Hibernate的使用者來說所操的心太多了，而且也不方便。在Maven2及以上版本中實現了傳遞依賴，如此對於Hibernate所依賴的包，Maven2會自動下載，開發人員只需關心Hibernate即可。所以可以看出列出所需要的每個jar是在maven1中的功能，Maven2以上版本認為自動下載是一種改進。

       這樣就產生了一個問題：Maven2以上版本雖然把編譯時需要的jar都下載了，但並不是所有編譯需要的jar在打成war包後執行時也需要。所以也就發現有許多的jar是不需要的，以至war包比較大。還會產生衝突。

       類包衝突的一個很大的原因即產類包之間的間接依賴引起的。每個顯式宣告的類包都會依賴於一些其它的隱式類包，這些隱式的類包會被maven間接引入進來，因而可能造成一個我們不想要的類包的載入，嚴重的甚至會引起類包之間的衝突。


例如:

servlet-api.jar

資訊: validateJarFile(D:\tomcat7\webapps\ipFilterM-0.0.1-SNAPSHOT\WEB-INF\lib\servlet-api-2.3.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class

造成這種情況的原因很可能是以下兩種情況：

一、專案的WEB-INF/lib下有servlet-api.jar，與Tomcat自帶的servlet-api.jar衝突了。

二、專案的WEB-INF/lib下有包含javax.servlet包的其他JAR包（如WebLogic 8.1的weblogic.jar），造成與Tomcat自帶的servlet-api.jar的衝突。

 

因為Tomcat的WebappClassLoader載入JAR包時會進行校驗，一旦發現上述衝突就會報出上面的異常。



解決方法

直接引用的包

要加上<scope>provided</scope>標籤

maven的dependency中有一個tag是<scope>option</scope>，其option有以下幾個值：

  compile， 預設值，適用於所有階段，會隨著專案一起釋出。

  provided，類似compile，期望JDK、容器或使用者會提供這個依賴。如servlet-api-2.3.jar。

  runtime， 在執行時使用，如JDBC驅動，適用執行和測試階段。   如plexus-utils-1.1.jar

  test     只在測試時使用，用於編譯和執行測試程式碼。不會隨專案釋出。如Junit-3.8.1.jar

  system， 類似provided，需要顯式提供包含依賴的jar，Maven不會在Repository中查詢它。

例如:

javax.servlet-3.0.1.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class

<dependency>
			<groupId>org.glassfish</groupId>
			<artifactId>javax.servlet</artifactId>
			<version>3.0.1</version>			
		</dependency>


在pom.xml中是直接引用的，則改為:
<dependency>
			<groupId>org.glassfish</groupId>
			<artifactId>javax.servlet</artifactId>
			<version>3.0.1</version>
			<scope>provided</scope>
		</dependency>



間接引用包

間接衝突解決方法一新建一個provided衝突包

新建一個衝突包，加上<scope>provided</scope>標籤
例如:servlet-api-2.3.jar
在pom.xml中沒有它的資訊，是其它包間接引用了它
則我們新建如下:
	<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>servlet-api</artifactId>
			<version>2.3</version>
			<scope>provided</scope>
		</dependency>


間接衝突解決方法二把衝突包依賴排除在外

這種情況下同一型別的包只保留一個最高階的，其他有衝突的低階包全部要排除在外
例子如下:

專案裡要用到commons-logging。它有幾個依賴，其中有一個是servlet-api-2.3.jar。現在我需要用到容器內的servlet-api的非同步功能，編譯的時候卻總是自動引用預設的2.3版本。請問哪位有經驗處理這樣的衝突，可以遮蔽掉servlet-api-2.3.jar這個依賴包。

如果你的工程是用maven管理的話，可以在commons-logging的依賴裡把servlet-api-2.3去除掉，再加入你所需要的版本的servlet-api依賴。大概的例子如下： 
<!--如果你的工程是用maven管理的話，可以在commons-logging的依賴裡把servlet-api-2.3去除掉，再加入你所需要的版本的servlet-api依賴。大概的例子如下：  -->
<dependency>
			<groupId>commons-logging</groupId>
			<artifactId>commons-logging</artifactId>
			<version>1.1.1</version>
			<exclusions>
				<exclusion>
					<groupId>javax.servlet</groupId>
					<artifactId>servlet-api</artifactId>
				</exclusion>
			</exclusions>
		</dependency>

<dependency>

			<groupId>org.mortbay.jetty</groupId>
			<artifactId>servlet-api-2.5</artifactId>
			<version>6.1.14</version>
			<scope>provided</scope>
		</dependency>
<!-- 指定scope為provided可以避免在釋出的時候把servlet-api包拷到lib目錄下。 -->


新增一個 衝突包的
provided的dependency   
針對每一個衝突包,要在它上級的包裡都加上exclusions把衝突包排除在外


新增和排除 都能在myeclipse中視覺化操作
如圖:






找間接依賴的包的兩個方法
在myeclipse的檢視中查詢



依賴樹
在cmd命令列中進入該專案的pom.xml所在位置:
輸入命令:
mvn dependency:tree



稍等一會我們就可以看到掃描出的依賴樹了，在裡面我們可以看到包的依賴關係


我掃描出的依賴樹如下:

根據以上方法依次解決每個包的依賴衝突後，該問題解決。


slf4j包錯誤

錯誤如下:
java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)V
at org.apache.commons.logging.impl.SLF4JLocationAwareLog.error(SLF4JLocationAwareLog.java:225)

at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150)
at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:895)


原因

slf4j錯誤本質上也是包的衝突錯誤，編譯時和執行時採用了不一樣的jar.它的報錯資訊說的是 在這個類中找不到對應的方法,這是因為 slf4j包不同的版本，方法名不一樣導致的。比如tomcat預設的使用某一版本的sjf4j包，但我們引入了一個新版本的包，這時候tomcat就會去找新版本的包，當然就找不到這個方法。

我們在myeclipse的pom.xml檢視中也能看到這樣的衝突,如圖:



那麼解決的方法跟上述的依賴包類似

解決方法

方案一

把衝突的包provided，看看依賴庫裡，只要是有slf4j字母的包全部provided,重新發布war後，war包解壓出來的工程lib中已經沒有slf4j字母的包了，那就ok了。
