maven项目生成的war包在tomcat下运行报错

maven项目在tomcat中运行 主要会有两种错误:

一是依赖包冲突

二是slf4j包错误

如下:

我们来分析原因和尝试解决:

依赖包冲突

原因

在Maven1中，需要把依赖所需要的包每个列出。这对于使用类似如Hibernate的用户来说所操的心太多了，而且也不方便。在Maven2及以上版本中实现了传递依赖，如此对于Hibernate所依赖的包，Maven2会自动下载，开发人员只需关心Hibernate即可。所以可以看出列出所需要的每个jar是在maven1中的功能，Maven2以上版本认为自动下载是一种改进。

       这样就产生了一个问题：Maven2以上版本虽然把编译时需要的jar都下载了，但并不是所有编译需要的jar在打成war包后运行时也需要。所以也就发现有许多的jar是不需要的，以至war包比较大。还会产生冲突。

       类包冲突的一个很大的原因即产类包之间的间接依赖引起的。每个显式声明的类包都会依赖于一些其它的隐式类包，这些隐式的类包会被maven间接引入进来，因而可能造成一个我们不想要的类包的载入，严重的甚至会引起类包之间的冲突。

例如:

servlet-api.jar

信息: 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

造成这种情况的原因很可能是以下两种情况：

一、项目的WEB-INF/lib下有servlet-api.jar，与Tomcat自带的servlet-api.jar冲突了。

二、项目的WEB-INF/lib下有包含javax.servlet包的其他JAR包（如WebLogic 8.1的weblogic.jar），造成与Tomcat自带的servlet-api.jar的冲突。

 

因为Tomcat的WebappClassLoader加载JAR包时会进行校验，一旦发现上述冲突就会报出上面的异常。

解决方法

直接引用的包

要加上<scope>provided</scope>标签

maven的dependency中有一个tag是<scope>option</scope>，其option有以下几个值：

  compile， 缺省值，适用于所有阶段，会随着项目一起发布。

  provided，类似compile，期望JDK、容器或使用者会提供这个依赖。如servlet-api-2.3.jar。

  runtime， 在运行时使用，如JDBC驱动，适用运行和测试阶段。   如plexus-utils-1.1.jar

  test     只在测试时使用，用于编译和运行测试代码。不会随项目发布。如Junit-3.8.1.jar

  system， 类似provided，需要显式提供包含依赖的jar，Maven不会在Repository中查找它。

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，则改为:

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

间接引用包

间接冲突解决方法一新建一个provided冲突包

新建一个冲突包，加上<scope>provided</scope>标签

例如:servlet-api-2.3.jar

在pom.xml中没有它的信息，是其它包间接引用了它

则我们新建如下:

<dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.3</version><scope>provided</scope></dependency>

间接冲突解决方法二把冲突包依赖排除在外

这种情况下同一类型的包只保留一个最高级的，其他有冲突的低级包全部要排除在外

例子如下:

项目里要用到commons-logging。它有几个依赖，其中有一个是servlet-api-2.3.jar。现在我需要用到容器内的servlet-api的异步功能，编译的时候却总是自动引用默认的2.3版本。请问哪位有经验处理这样的冲突，可以屏蔽掉servlet-api-2.3.jar这个依赖包。

如果你的工程是用maven管理的话，可以在commons-logging的依赖里把servlet-api-2.3去除掉，再加入你所需要的版本的servlet-api依赖。大概的例子如下： 

<!--如果你的工程是用maven管理的话，可以在commons-logging的依赖里把servlet-api-2.3去除掉，再加入你所需要的版本的servlet-api依赖。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为provided可以避免在发布的时候把servlet-api包拷到lib目录下。 -->

新增一个 冲突包的

provided的dependency   

针对每一个冲突包,要在它上级的包里都加上exclusions把冲突包排除在外

新增和排除 都能在myeclipse中可视化操作

如图:

找间接依赖的包的两个方法

在myeclipse的视图中查找

依赖树

在cmd命令行中进入该项目的pom.xml所在位置:

输入命令:

mvn dependency:tree

稍等一会我们就可以看到扫描出的依赖树了，在里面我们可以看到包的依赖关系

我扫描出的依赖树如下:

根据以上方法依次解决每个包的依赖冲突后，该问题解决。

slf4j包错误

错误如下:

java.lang.NoSuchMethodError: org.slf4j.spi.LocationAwareLogger.log(Lorg/slf4j/Marker;Ljava/lang/String;ILjava/lang/String;[Ljava/lang/Object;Ljava/lang/Throwable;)Vat org.apache.commons.logging.impl.SLF4JLocationAwareLog.error(SLF4JLocationAwareLog.java:225)at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:319)at com.alibaba.citrus.webx.context.WebxComponentsLoader.initWebApplicationContext(WebxComponentsLoader.java:117)at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:112)at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4779)at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5273)at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150)at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:895)

原因

slf4j错误本质上也是包的冲突错误，编译时和运行时采用了不一样的jar.它的报错信息说的是 在这个类中找不到对应的方法,这是因为 slf4j包不同的版本，方法名不一样导致的。比如tomcat默认的使用某一版本的sjf4j包，但我们引入了一个新版本的包，这时候tomcat就会去找新版本的包，当然就找不到这个方法。

我们在myeclipse的pom.xml视图中也能看到这样的冲突,如图:

那么解决的方法跟上述的依赖包类似

解决方法

方案一

把冲突的包provided，看看依赖库里，只要是有slf4j字母的包全部provided,重新发布war后，war包解压出来的工程lib中已经没有slf4j字母的包了，那就ok了。
