无法找到XML模式名称空间的Spring NamespaceHandler [http://www.springframework.org/schema/batch]

分类：编程问答

如何解决无法找到XML模式名称空间的Spring NamespaceHandler [http://www.springframework.org/schema/batch]

通过CommandLineJobRunner运行作业：java -jar batchprimer-1.0.jar META-INF / spring / module-context.xml job1

即使具有完整的目标文件夹，你也必须提供java命令的类路径信息，以简化配置，你可以使用多合一可执行jar（例如，使用maven-shade-plugin或可执行shell脚本（.bat /.sh）和所有需要的库，例如，使用appassembler-maven-plugin

maven-shade-plugin示例配置（创建其他jar）：

<plugin>
    <!-- create an all-in-one executable jar with maven-shade-plugin
         bound to phase:package 
         special handling for spring.handlers/spring.schemas files
         to prevent overwriting (maven-shade-plugin joins them to
         one file) 

         usage:
         cd to <project>/target
         java -jar hello-world-java-1.0-SNAPSHOT-executable.jar spring/batch/job/hello-world-job.xml helloWorldJob
         -->                     
    <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>org.springframework.batch.core.launch.support.CommandLineJobRunner</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>
            </configuration>
        </execution>
    </executions>
</plugin>

示例应用程序组装程序配置（创建子文件夹结构和.bat / .sh）：

<plugin>
    <artifactId>appassembler-maven-plugin</artifactId>
    <groupId>org.codehaus.mojo</groupId>
    <version>1.1.1</version>
    <configuration>
        <repositoryLayout>flat</repositoryLayout>
        <installArtifacts>false</installArtifacts>
        <target>${project.build.directory}/appassembler</target>
        <defaultJvmSettings>
            <initialMemorySize>512M</initialMemorySize>
            <maxMemorySize>1024M</maxMemorySize>
            <extraArguments>
                <extraArgument>-Dlog4j.configuration=../etc/log4j/log4j.properties</extraArgument>
            </extraArguments>
        </defaultJvmSettings>
        <configurationDirectory>etc</configurationDirectory>
        <daemons>
            <daemon>

                <mainClass>org.springframework.batch.core.launch.support.CommandLineJobRunner</mainClass>
                <commandLineArguments>
                    <commandLineArgument>spring/job-runner.xml</commandLineArgument>
                    <commandLineArgument>helloWorldJob</commandLineArgument>
                    <commandLineArgument>input.file.pattern=file:.../**/*.txt</commandLineArgument>

                    <platform>booter-windows</platform>
                </platforms>
            </daemon>
        </daemons>
    </configuration>

            </goals>
        </execution>
    </executions>
</plugin>

解决方法

我正在使用Spring Batch为我们的数据仓库构建累积快照，并且遇到了无法确定的配置障碍。

我已经使用Spring Template Project使用STS（SpringSource Tool Suite 2.8.1）创建了一个简单Spring Batch 项目。这些是我创建的两个xml配置文件：

launch-context.xml

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

<context:component-scan base-package="edu.kdc.visioncards" />

<jdbc:initialize-database data-source="dataSource">
    <jdbc:script location="${batch.schema.script}" />
</jdbc:initialize-database>

<batch:job-repository id="jobRepository" />

<import resource="classpath:/META-INF/spring/module-context.xml" />

and module-context.xml

 <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

xsi:schemaLocation="http://www.springframework.org/schema/batch http://www.springframework.org/schema/batch/spring-batch-2.1.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

<description>Example job to get you started. It provides a skeleton for a typical batch application.</description>

<batch:job id="job1">
    <batch:step id="step1"  >           
        <batch:tasklet transaction-manager="transactionManager" start-limit="100" >
            <batch:chunk reader="reader" writer="writer" commit-interval="1" />
        </batch:tasklet>
    </batch:step>
</batch:job> 

</beans>

问题

我运行以下命令来编译和打包项目：mvn clean compile install

然后我做如下：

  1. cd到目标文件夹

  2. 通过CommandLineJobRunner运行作业：java -jar batchprimer-1.0.jar META-INF / spring / module-context.xml job1

我收到以下错误：

Additional Stuff

在使用mvn install命令填充的目标文件夹中，我具有以下内容：

  1. 一个类文件夹
  2. 一个包含我所有maven依赖项的lib文件夹
  3. 一个maven-archiver文件夹
  4. 一个测试类的文件夹
  5. 一个batchprimer-1.0.jar

Inside the jar,in the META-INF / MANIFEST.MF中。我有如下内容：

Manifest-Version: 1.0

Archiver-Version: Plexus Archiver

Created-By: Apache Maven

Built-By: dpardo

Build-Jdk: 1.6.0_20

Main-Class: org.springframework.batch.core.launch.support.CommandLineJ
 obRunner

Class-Path: lib/spring-jdbc-3.0.6.RELEASE.jar lib/spring-beans-3.0.6.R
 ELEASE.jar lib/spring-core-3.0.6.RELEASE.jar lib/spring-asm-3.0.6.REL

 ar lib/slf4j-log4j12-1.5.8.jar lib/slf4j-api-1.5.8.jar lib/mysql-conn
 ector-java-5.1.3.jar

因此，我认为这不是类路径问题，因为在控制台中似乎正在查找jar。

我尝试过的

根据错误，我粘贴了以下网址

http://www.springframework.org/schema/batch/

并且Spring Batch的命名空间地址似乎正确。我也没有发现任何有用的东西。我在某处读到“某些内容”可能会覆盖文件的命名空间，但并没有真正理解为什么，什么和/或如何解决它。

这是开箱即用的，没有做任何修改，附加组件或任何其他操作就无法正常工作。有任何想法吗？

谢谢

SOLUTION

除了下面标记为正确的解决方案。我还必须将launch-context.xml从组件扫描更改为常规的弹簧接线，如下所示：

<!-- Commented this 
<context:property-placeholder location="classpath:batch.properties" />  


<jdbc:initialize-database data-source="dataSource">
    <jdbc:script location="${batch.schema.script}" />
</jdbc:initialize-database>
-->
<!-- Replace it with this below -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="${batch.jdbc.driver}" />
    <property name="url" value="${batch.jdbc.url}" />
    <property name="username" value="${batch.jdbc.user}" />
    <property name="password" value="${batch.jdbc.password}" />
</bean>

<bean id="transactionManager"
    class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
    lazy-init="true">
    <property name="dataSource" ref="dataSource" />
</bean>

<bean id="placeholderProperties"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location" value="classpath:batch.properties" />
    <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
    <property name="ignoreUnresolvablePlaceholders" value="true" />
    <property name="order" value="1" />
</bean>
