XMLBeanDefinitionStoreException：找不到元素“bean”的声明

Question

我正在尝试以下代码：http://www.dineshonjava.com/2012/12/spring-mvc-with-hibernate-crud-example.html#.Uus0bvnoSGc sdnext-servlet.xml 如下

<beans xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans" xsi:schemalocation="

</bean>

  <bean class="org.springframework.orm.hibernate3.HibernateTransactionManager" id="hibernateTransactionManager">

  </bean>
</beans>

我遇到了异常

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 12 in XML document from ServletContext resource [/WEB-INF/config/sdnext-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 12; columnNumber: 62; cvc-elt.1: Cannot find the declaration of element 'beans'.

我不知道出了什么问题。请帮忙

Answer 1

把xml命名空间定义改成这个

<beans  xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" 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-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">

它应该可以工作

问题在于您对xsi:schemalocation 的定义，拼写错误是L 它应该是大写，只有这样它才能识别标签。

Answer 2

这对我有用：

需要更改默认命名空间，如下所示：

<beans:beans xmlns="http://www.springframework.org/schema/security"
       xmlns:beans="http://www.springframework.org/schema/beans" 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.xsd
       http://www.springframework.org/schema/security
       http://www.springframework.org/schema/security/spring-security-3.2.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd"
       xmlns:context="http://www.springframework.org/schema/context">

    <mvc:resources mapping="/scripts/**" location="/scripts/" />
    <mvc:resources mapping="/resources/**" location="/resources/" />
    <context:component-scan base-package="com.dewsoftware.webapp" />

</beans:beans>

这有点牵强，但它可能会发生在其他人身上，就像发生在我身上一样。

我正在用maven-assembly-plugin 打包一个胖罐子，并在尝试执行我的主类时得到了XMLBeanDefinitionStoreException。插件配置如下：

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>3.1.0</version>
        <configuration>
          <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
          </descriptorRefs>
          <archive>
            <manifest>
              <mainClass>com.bigcompany.module.MyMainClass</mainClass>
            </manifest>
          </archive>
        </configuration>
        <executions>
          <execution>
            <id>make-assembly</id> this is used for inheritance merges
            <phase>package</phase> bind to the packaging phase
            <goals>
              <goal>single</goal>
            </goals>
          </execution>
        </executions>
      </plugin>

我的解决方案是使用不同的插件：maven-shade-plugin。配置如下：

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>1.5</version>
        <executions>
            <execution>
                <phase>package</phase>
                <goals>
                    <goal>shade</goal>
                </goals>
                <configuration>
                    <transformers>
                        <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                            <mainClass>com.bigcompany.module.MyMainClass</mainClass>
                        </transformer>
                        <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>
                    <shadedArtifactAttached>true</shadedArtifactAttached>
                    <!-- configures the suffix name for the executable jar here it will be '<project.artifact>-<project.version>-executable.jar' -->
                    <shadedClassifierName>executable</shadedClassifierName>
                    <filters>
                        <filter>
                            <artifact>*:*</artifact>
                            <excludes>
                                <exclude>META-INF/*.SF</exclude>
                                <exclude>META-INF/*.DSA</exclude>
                                <exclude>META-INF/*.RSA</exclude>
                            </excludes>
                        </filter>
                    </filters>
                </configuration>
            </execution>
        </executions>
    </plugin>

生成的 jar 确实使用与其他插件生成的 jar 引发异常的同一命令行无异常地执行。

更改命名空间：<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="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-4.3.xsd">
