縫出口數據表以Excel格式

Question

我嘗試導出richdata表使用縫到Excel，並按照 http://docs.jboss.org/seam/2.1.0.GA/reference/en-US/html/excel.html#excel.intro

它指示「要包含在應用程序中微軟的Excel電子表格應用程序的支持，包括jboss-您的WEB-INF/lib目錄中的seam-excel.jar以及jxl.jar JAR文件。「

我發現下面的兩個依賴在線罐子..

戰爭的pom.xml

<dependency> 
    <groupId>org.jboss.seam</groupId> 
    <artifactId>jboss-seam-excel</artifactId> 
    <version>2.2.0.GA</version> 
</dependency> 
<dependency> 
    <groupId>net.sourceforge.jexcelapi</groupId> 
    <artifactId>jxl</artifactId> 
    <version>2.6.12</version> 
</dependency> 

的web.xml

<servlet> 
     <servlet-name>Document Store Servlet</servlet-name> 
     <servlet-class>org.jboss.seam.document.DocumentStoreServlet</servlet-class> 
    </servlet> 

    <servlet-mapping> 
     <servlet-name>Document Store Servlet</servlet-name> 
     <url-pattern>*.xls</url-pattern> 
    </servlet-mapping> 

    <context-param> 
    <param-name>webAppRootKey</param-name> 
    <param-value>seam-excel</param-value> 
    </context-param> 

的components.xml

<components 
     xmlns:excel="http://jboss.com/products/seam/excel" 
     xmlns:document="http://jboss.com/products/seam/document" 

     http://jboss.com/products/seam/excel http://jboss.com/products/seam/excel-2.1.xsd 
     http://jboss.com/products/seam/document http://jboss.com/products/seam/document-2.1.xsd"> 

     <excel:document-store use-extensions="true"/> 
     <document:document-store use-extensions="true"/> 
</components> 

早些時候，我也被具有以下components.xml中

<excel:excelFactory> 
   <property name="implementations"> 
      <key>myExcelExporter</key> 
      <value>my.excel.exporter.ExcelExport</value> 
   </property> 
</excel:excelFactory> 

這是導致部署的異常，也沒有人在他們的代碼中提到這個問題，我擺脫了這一點，並部署例外。

的jboss-縫Excel的2.1.2.jar和JXL-2.6.12.jar是在WEB-INF/lib目錄

但部署，我沒有找到.. org.jboss.seam.excel.DocumentStoreServlet任何地方，在的web.xml所以使用org.jboss.seam.document.DocumentStoreServlet

但是，我得到財產未發現異常就在登錄的時候，下面是完整的錯誤堆棧跟蹤.. loginAction.stationID無關與我的變更...

Deployment Exception : Could not create Component: org.jboss.seam.excel.excelFactory 
**Could not create Component: org.jboss.seam.excel.excelFactory** 

PropertyNotFoundException在我添加seam excel依賴項時發生。

我的依賴關係樹看到這個.. mvn dependency:tree，發現這個..

[INFO] +- org.jboss.seam:jboss-seam-excel:jar:2.2.0.GA:compile 
[INFO] |  \- org.jboss.seam:jboss-seam:ejb:2.2.0.GA:compile

Excel的罐子自帶的jboss-縫EJB和jboss-EL等。我認爲org.jboss.el： jboss-el與我的項目中的一個已經碰撞..也.. .. jboss-seam：ejb：2.2.0.GA ..，試圖把下面的排除在maven ..但dint工作要麼..

<dependency> 
     <groupId>org.jboss.seam</groupId> 
     <artifactId>jboss-seam-excel</artifactId> 
     <version>2.2.0.GA</version> 
     <exclusions> 
      <exclusion> 
       <groupId>ejb</groupId> 
       <artifactId>ejb</artifactId> 
      </exclusion> 
      <exclusion> 
       <groupId>javax.el</groupId> 
       <artifactId>el-api</artifactId> 
      </exclusion> 
     </exclusions> 
    </dependency> 

Answer 1

，因爲我以爲，我不排除依賴正確，並與其他依賴相沖突。

這裏是正確的版本...

<dependency> 
    <groupId>org.jboss.seam</groupId> 
    <artifactId>jboss-seam-excel</artifactId> 
    <version>2.2.0.GA</version> 
    <exclusions> 
     <exclusion> 
      <groupId>org.jboss.seam</groupId> 
      <artifactId>jboss-seam</artifactId> 
     </exclusion> 
     <exclusion> 
      <groupId>org.jboss.el</groupId> 
      <artifactId>jboss-el</artifactId> 
      </exclusion> 
    </exclusions> 
</dependency> 

希望這有助於別人的未來。我必須說這個功能的記錄很差，而且必須去幾個論壇去了解究竟需要什麼。我將停止使用POI方法導出excel :)。

Answer 2

你正在使用哪個JBoss版本？我假設的JBoss 5

入住此引用： https://community.jboss.org/thread/186791

這是一個較舊的版本，但也是有幫助的：

https://community.jboss.org/thread/184757

我剪切並粘貼下面的代碼，因爲我不目前無法訪問代碼，但如果不正確，它將很接近。 你需要在web.xml參考

<servlet-name>Document Store Servlet Excel</servlet-name> 
<servlet-class>org.jboss.seam.excel.DocumentStoreServlet</servlet-class> 


<servlet-mapping> 
<servlet-name>Document Store Servlet Excel</servlet-name> 
<url-pattern>*.xls</url-pattern> 
</servlet-mapping> 


<context-param> 
<param-name>webAppRootKey</param-name> 
<param-value>seam-excel</param-value> 
</context-param> 

的jboss-web.xml中

<jboss-web> 
<class-loading java2ClassLoadingCompliance="false"> 
<loader-repository> 
seam.jboss.org:loader=seam-excel 
<loader-repository-config>java2ParentDelegation=false</loader-repository-config> 
</loader-repository> 
</class-loading> 
</jboss-web> 

和components.xml中

<components xmlns:excel="http://jboss.com/products/seam/excel" 
xmlns:document="http://jboss.com/products/seam/document" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://jboss.com/products/seam/document http://jboss.com/products/seam/document-2.1.xsd 
http://jboss.com/products/seam/excel http://jboss.com/products/seam/excel-2.1.xsd"> 

<document:document-store use-extensions="true"></document:document-store> 

</components>
