怎么spring security 和maven，spring,结合jar包冲突和依赖关系问题解决办法。

  Eclipse IDE开发工具           spring security 和maven，spring,发生jar包冲突和依赖关系问题怎么办：

1：首先用maven命令对项目进行项目转化，（下载jar包）

    mvn eclipse:eclipse -Dwtpversion=2.0 运行后再执行

    mvn clean install -Dmaven.skip.test=true 进行打包。

    若是出现局部错误可能：

    （1）：prepertities--project facts  JDK版本问题 1.4改为1.5,1.6以上

    （2）：jre错误版本号，或者是没有用本地的jre版本。在preperties-bulidpath-先remove再add library选择本地jre.

2：java.lang.IllegalArgumentException: Document base D:\myeclipse_workerspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp2\wtpwebapps\ehp-web does not exist or is not a readable directory

说明ehp-web没有部署成功。、

在 自己的eclipse空间中 D:\myeclipse_workerspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp2\wtpwebapps查看ehp-web是否部署成功了。

解决办法：deployment assembly下

删除红框内的jar包

为什么：个人理解 eclipse 的自动转化jar包有冲突，tomcat无法识别。

3：错误点发生改变如下：文件找不到。将java工程打成的jar包加到D:\myeclipse_workerspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp2\wtpwebapps\ehp-web  的lib下：

第4步：新的问题点：

spring jar包运行的是2.0而不是spring3.07以上，所以出现错误。

原因是：mvn加载jar包时下载了很多2.0版本的jar包，在tomcat集成：D:\myeclipse_workerspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp2\wtpwebapps\ehp-web  的lib下

删除不要的jar包。4个：spring-2.0.jar ;spring-dao-2.0-m2.jar;spring-remoting-2.0-m2.jar;spring-support-2.0-m2.jar删除即可。

5步：

ERROR(ContextLoader:318) Context initialization failed

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.filterChains': Cannot resolve reference to bean 'org.springframework.security.web.DefaultSecurityFilterChain#0' while setting bean property 'sourceList' with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.web.DefaultSecurityFilterChain#0': Cannot resolve reference to bean 'captchaValidationProcessingFilter' while setting constructor argument with key [1]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'captchaValidationProcessingFilter' defined in class path resource [applicationContext-security.xml]: Cannot resolve reference to bean 'captchaService' while setting bean property 'captchaService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'captchaService' defined in class path resource [applicationContext-security.xml]: Cannot resolve reference to bean 'imageCaptchaService' while setting bean property 'jcaptchaService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'imageCaptchaService' defined in class path resource [applicationContext-security.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [com.octo.captcha.service.image.DefaultManageableImageCaptchaService]: Constructor threw exception; nested exception is java.lang.NoSuchMethodError: com.octo.captcha.service.captchastore.CaptchaStore.initAndStart()V

at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveValueIfNecessary(BeanDefinitionValueResolver.java:107)

出现此问题是因为jcaptcha-1.0.jar；jcaptcha-api-1.0.jar；jcaptcha-all-1.0-RC6.jar；

删除前两个jar包。

    6步：

   org.apache.catalina.core.ApplicationContext log

    严重: StandardWrapper.Throwable

    java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileItemFactory

   at java.lang.Class.getDeclaredConstructors0(Native Method)

解决办法：加入commons-fileupload-1.2.2.jar；commons-io-2.2.jar。即可。

---

经过6步法则，终于大功告成。
