加载spring xml会抛出SAXParseException

我写了一个在eclipse中使用spring和hibernate的应用程序。在eclipse中运行时应用程序运行正常。我使用maven将该项目打包到一个可执行的jar文件中，当我运行jar时遇到SAXParseException

这是例外

org.xml.sax.SAXParseException; lineNumber: 17; columnNumber: 69; schema_reference.4:     Failed to read schema document 'http://www.springframework.org/schema/beans/spring-beans-2.5.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the doc

我用来加载弹簧容器的代码是

ApplicationContext appContext = new ClassPathXmlApplicationContext("spring.xml");

项目结构类似于

Project
-----------src/main/java
-----------src/main/resources
-----------pom.xml

文件spring.xml位于src / main.resources

中

我的pom.xml看起来像

2 个答案:

答案 0 :(得分：2)

问题似乎在阴影插件中。在不同的弹簧罐中定义的命名空间处理程序和模式将被覆盖。将以下内容添加到树荫插件配置的变换器部分，看看它是如何进行的。

<transformer
    implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
    <resource>META-INF/spring.handlers</resource>
</transformer>
<transformer
    implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
    <resource>META-INF/spring.schemas</resource>
</transformer>

此外，请考虑使用无版本模式定义，以便您不知道版本号更改 - 所有XSD文件首先在类路径中进行验证，并且只有在未找到时才会进入网络。

答案 1 :(得分：1)

<dependency>  
    <groupId>org.springframework</groupId>  
    <artifactId>spring-webmvc</artifactId>  
    <version>${spring.version}</version>  
</dependency>

 <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-remoting</artifactId>
    <version>2.0.8</version>
</dependency>

<dependency>  
    <groupId>org.springframework</groupId>  
    <artifactId>spring-web</artifactId>  
    <version>${spring.version}</version>  
</dependency>

这些依赖关系很麻烦。你正在将Spring 4.0.3与Spring 2.0.8 jar混合在一起，永远不要混合不同版本的框架（无论是spring，hibernate，jsf等），因为等待发生的麻烦。

在你的情况下，这导致从2.0.8版本的spring中提取spring-core，spring-beans等，其中不包含2.5 xsd文件。

只需删除spring-remoting依赖关系（请注意，您也可以移除spring-web，因为spring-webmvc取决于spring-web。

<dependency>  
    <groupId>org.springframework</groupId>  
    <artifactId>spring-webmvc</artifactId>  
    <version>${spring.version}</version>  
</dependency>

另一个注意事项建议在使用xml配置时使用无版本的xsd文件，这将确保您始终拥有属于您的spring版本的最新版本。

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

编辑：添加了maven更新

注意到你正在使用shade插件制作一个可执行的jar。在制作可执行jar时，某些文件（spring.handlers和spring.schemas被覆盖。只有1个架构可用。你必须告诉shade插件合并这些文件而不是覆盖它们。

你需要配置你需要添加这样的阴影插件到你的阴影插件配置

<configuration>
            <transformers>
                <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                    <resource>META-INF/spring.handlers</resource>
                </transformer>
                <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                    <resource>META-INF/spring.schemas</resource>
                </transformer>
            </transformers>
        </configuration>
