实现JAX-WS，如果忘了jaxws-spring这个jar的奇怪现象

之前参考网上的例子，练习了下并完好在本地实现了一个演示，但是后来很长时间没搞了，昨天重新弄的时候发现了各种奇怪现象：

1. applicationContext.xml 在第一行的前面有个红叉叉，鼠标放上去说这个错：

Referenced file contains errors (http://jax-ws.dev.java.net/spring/servlet.xsd). For more information, right click on the message in the Problems View and select "Show Details..."

我用Maven能正确打包，但是部署到Tomcat就发生了下面的错误：

SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

还出现了不能解压这个包的错误提示：

SEVERE: Exception fixing docBase for context [/spring_ws]java.util.zip.ZipException: error in opening zip fileSEVERE: Error starting static Resourcesjava.lang.IllegalArgumentException: Invalid or unreadable WAR file : error in opening zip file

接下来 Tomcat 给出的信息让人摸不着头脑了：

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 19 in XML document from class path resource [applicationContext.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'aop:config'.org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 27 in XML document from class path resource [applicationContext.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'wss:binding'.

网上搜了下，说http://jax-ws.dev.java.net/spring/servlet.xsd 地址不对的有之，说需要在applicationContext.xml 里加上 http://www.springframework.org/schema/aop/spring-context-3.0.xsd 的有之，说服务器自带的 XML Parser 和项目里的 XML Parser 有冲突的有之。

当然不能说他们的说法不对，正如网上一老兄说的：“generically this exception will be thrown for many reasons.” 

后来看到了 Schemas are located at the root of the jaxws-spring.jar file  并仔细查看自己的 Tomcat 的日志：

org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://jax-ws.dev.java.net/spring/servlet.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

这才怀疑是不是自己的配置错了，一看 pom.xml 才知道我把 jaxws-spring 这个 dependency 给注释掉了：

<!-- <dependency><groupId>org.jvnet.jax-ws-commons.spring</groupId><artifactId>jaxws-spring</artifactId><version>1.8</version><exclusions>  <exclusion>           <groupId>org.springframework</groupId>      <artifactId>spring-core</artifactId>          </exclusion>          <exclusion>           <groupId>org.springframework</groupId>      <artifactId>spring-context</artifactId>          </exclusion>          <exclusion>           <groupId>com.sun.xml.stream.buffer</groupId>      <artifactId>streambuffer</artifactId>          </exclusion>          <exclusion>           <groupId>org.jvnet.staxex</groupId>      <artifactId>stax-ex</artifactId>          </exclusion></exclusions></dependency>-->

把这个注释去掉，重新打包，tomcat 才正常解压。哎，耽误了一天的功夫，不知道当初为什么把注释掉了。惭愧！
