(adsbygoogle = window.adsbygoogle || []).push({}); 如何解決Java：Spring：讀取spring context.xml時發生XML沖突'identifiedType'的重復定義？

您的schemaLocation是版本（spring-beans-3.2.xsd）和非版本（spring-tx.xsd）模式名稱的混合。您應始終使用一種樣式或另一種樣式，而不要混合使用兩種樣式。我懷疑這里發生的事情是您明確引用了3.2版本的spring-beans，但是您的未版本化架構中的一個導入了相同架構的另一個版本，導致的兩個定義沖突beans:identifiedType。

解決方法

任何建議或幫助，我們將不勝感激。

參考鏈接很多，但是沒有明確的解決方案。我想知道Spring項目如何與返回XMLType輸出的PLSQL過程交互。您將需要XMLParser，然后與Spring一起使用時，我們所有人都會收到此錯誤。有人有什么建議嗎？

我有一個運行良好的Maven spring應用程序（mvc / Rest），并且添加了以下與PLSQL過程進行交互的依賴項，

<dependency><groupId>com.oracle</groupId><artifactId>ojdbc6</artifactId><version>11.2.0.4</version> </dependency> <dependency><groupId>com.oracle</groupId><artifactId>xdb6</artifactId><version>11.2.0.4</version> </dependency> <dependency><groupId>com.xmlparserv2</groupId><artifactId>xmlparserv2</artifactId><version>11.1.1</version> </dependency>

包含xdb6和之后xmlparserv2，在Spring應用程序啟動時（運行服務器時）出現以下錯誤

假設我刪除了Line16及其引用，那么將相同的錯誤拋出在另一行，例如第13行

更新1

根據發布的答案，它說有一個快速的解決方案，

要覆蓋xmlparserv2.jar所做的更改，請將以下JVM屬性添加到應用程序服務器啟動參數中。java.xml.parsers.FactoryFinder邏輯將首先檢查環境變量。

-Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl -Djavax.xml.transform.TransformerFactory=com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl

如鏈接https://community.oracle.com/thread/1080787中明確指出的那樣，不建議這樣做

在Maven Spring項目中，通過在％PROJECT_HOME％/ src / main /resources目錄中創建以下文件來覆蓋xmlparserv2.jar設置：

%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.DocumentBuilderFactory (which defines com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl as the default)%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.SAXParserFactory (which defines com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl as the default)%PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.transform.TransformerFactory (which defines com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl as the default)

我不清楚。

如何將這些文件拖放到提到的目錄中？這是推薦的解決方案嗎？

更新2

我嘗試添加VM參數-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl，它有效。

但是，尋找替代的，更合適的解決方案。這只是一個解決方法。當通過說Jenkins將應用程序部署到服務器時，不適合設置這些與XML解析器相關的VM參數設置。

@Ian Roberts的答案解決了這個問題。我清理了context.xml以一致地使用xsd的版本號。
