Question

我已经将我的应用程序及其依赖项打包在一个jar中，当我开始时，我收到一条错误消息，因为它似乎试图通过http获取模式文件：

org.xml.sax.SAXParseException; lineNumber: 7; columnNumber: 123; schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/beans/factory/xml/spring-beans.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>.
    ...
Caused by: java.net.ConnectException: Connection refused: connect
    ...

My Spring xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
         http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
         http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    ...
</beans>

当我在我的罐子里搜索时，我发现这些文件：

/org/springframework/beans/factory/xml/spring-beans-2.0.xsd
/org/springframework/beans/factory/xml/spring-beans-2.5.xsd
/org/springframework/beans/factory/xml/spring-beans-3.0.xsd
/org/springframework/beans/factory/xml/spring-beans-3.1.xsd
/org/springframework/beans/factory/xml/spring-beans-3.2.xsd

我认为路径的factory/xml部分是问题的一部分？我像这样启动（Apache Camel）应用程序：

java -Dserver=acpt -jar my_app-1.0.0-SNAPSHOT-jar-with-dependencies.jar -ac META-INF/spring/my_app.xml

我的罐子装配不正确吗？或者需要我以某种方式告诉Spring一些路径？或者我应该将类路径设置为jar中特定的类型？或者它可能与Camel有关（因为我正在运行org.apache.camel.spring.Main）？我真的不知道从哪里开始，欢迎任何建议！

我介绍了一个手动的构建后修补步骤，我找不到任何修复方法。问题是META-INF/spring.schemas和META-INF/spring.handlers只包含Camel的东西（在构建期间的某些时候被覆盖？），而不是Spring的东西。

我通过创建两个文件missing.spring.handlers和missing.spring.schemas来解决此问题，其中包含以下内容：

http\://www.springframework.org/schema/aop/spring-aop.xsd=org/springframework/aop/config/spring-aop-3.0.xsd

和

http\://www.springframework.org/schema/p=org.springframework.beans.factory.xml.SimplePropertyNamespaceHandler
http\://www.springframework.org/schema/util=org.springframework.beans.factory.xml.UtilNamespaceHandler
http\://www.springframework.org/schema/context=org.springframework.context.config.ContextNamespaceHandler
http\://www.springframework.org/schema/jee=org.springframework.ejb.config.JeeNamespaceHandler
http\://www.springframework.org/schema/lang=org.springframework.scripting.config.LangNamespaceHandler
http\://www.springframework.org/schema/task=org.springframework.scheduling.config.TaskNamespaceHandler
http\://www.springframework.org/schema/aop=org.springframework.aop.config.AopNamespaceHandler

然后我做了一个shell脚本，几乎可以做到：

cd target
unzip my.jar
cat path/to/missing.spring.handlers >>META-INF/spring.handlers
cat path/to/missing.spring.schemas  >>META-INF/spring.schemas
zip back my.jar again

不是一个简洁的解决方案，但它确实有效。

在启动期间，Spring似乎无法找到spring-beans-x.y.xsd
