我無法找出其中的問題，我的jar文件不具有此config文件夾

DaoMain.java

如何解決這個問題？

後蹤跡作爲文本而不是image – Jens

位於jar中的'dataSupport.xml'位於哪裏？ – Jens

構建不包括此dataSupport.xml文件，這是我有錯誤 – sailaja

您的XML文件格式不正確。

雖然我不知道這是否是這個問題，但它可能是您的項目爲什麼沒有正確取得文件的根本原因。

您的<beans>標籤沒有結束標籤。嘗試將</beans>放在文件的末尾。

此外，您的pom.xml文件具有相同的問題。 <project>未關閉。嘗試將</project>置於文件末尾。

這兩個文件都是正確的，但錯過了粘貼在這裏，爲這個愚蠢的錯誤道歉...試過這個問題是無法用這個bean文件建立jar文件，因此得到錯誤...但我可以運行應用程序使用在eclipse中的Java應用程序，但我需要jar文件將其添加到批處理文件中...運行它 – sailaja

貌似主要問題是在這一行：

new ClassPathXmlApplicationContext("classpath:/org/postprocessor/config/dataSupport.xml");

你正試圖從classpath建立上下文。因此，您必須從項目的類路徑中找到您的配置文件。

您使用Maven用於構建您的項目。Maven的定義項目結構代碼源和資源：

/src/main/java 
/src/main/resorces

你可以找到更多在這裏：Introduction to the Standard Directory Layout

如果你想使你的文件從classpath中你訪問必須完全置於 - resources/文件夾：

現在你的main（）將是這樣的：

public static void main(String[] args) { 
    ApplicationContext ctx= new ClassPathXmlApplicationContext("classpath:config/dataSupport.xml"); 
    Object dataSource = ctx.getBean("userRepo"); 
    System.out.println(dataSource.getClass().getName()); 
    // use your beans here

我剛創建演示豆。這裏是輸出：

2017-03-20 15:22:40 INFO ClassPathXmlApplicationContext - Refreshing org[email protected]16f65612: startup date [Mon Mar 20 15:22:40 EET 2017]; root of context hierarchy 
2017-03-20 15:22:40 INFO XmlBeanDefinitionReader - Loading XML bean definitions from class path resource [config/dataSupport.xml] 
demo.repository.UserRepository

BTW您可以使用try with resources的應用程序上下文：

try(ClassPathXmlApplicationContext ctx = 
    new ClassPathXmlApplicationContext("classpath:config/dataSupport.xml")) { 
    // use your beans here 
}

其他資源：

我認爲有以下應該工作：

ApplicationContext ctx= new ClassPathXmlApplicationContext("org/postprocessor/config/dataSupport.xml");

你並不需要指定「類路徑」，因爲你已經在使用ClassPathXmlApplicationContext的，你必須在一開始額外斜槓。

這不提供問題的答案。要批評或要求作者澄清，請在其帖子下方留言。 - [來自評論]（/ review/low-quality-posts/15641594） – DimaSan

OP問：「如何解決這個問題？答案是：「將你的配置文件移動到正確的位置」。有沒有不清楚這件事？ – ninj

您可以通過添加一些解釋來提高帖子的質量。請記住，您將來會爲讀者回答問題，而這些人可能不知道您的代碼建議的原因。 – DimaSan

默認情況下Maven的編譯器插件，不包括非Java文件。這給你留下了兩個選擇。
1.將資源文件（的.properties，.XML等），以「的src/main /資源」（recomended）
2.使用Maven插件資源

<plugin> 
    <artifactId>maven-resources-plugin</artifactId> 
    <version>2.6</version> 
    <executions> 
     <execution> 
     <id>copy-resources</id>
