Java 找不到Spring NamespaceHandler util

当我使用spring v.3.1执行java项目时，出现以下错误：

Bean 'configParser'; nested exception is 

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/util]
Offending resource: class path resource [Services.xml]
Bean 'configParser'

我的POM具有以下依赖项：

<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>3.1.2.RELEASE</version>

            <artifactId>spring-aop</artifactId>
            <version>3.1.2.RELEASE</version>
        </dependency>

如果输出调试消息，则可以识别使用了各种版本号。这可能是原因吗？如何定义数字

我还使用maven汇编插件创建一个可执行的jar文件。

模式

http://www.springframework.org/schema/util/spring-util.xsd

，

http://www.springframework.org/schema/util/spring-util-3.1.xsd

（以及带有这些版本的版本）附带了

Springbeans-.RELEASE.jar

http\://www.springframework.org/schema/beans/spring-beans-2.0.xsd=org/springframework/beans/factory/xml/spring-beans-2.0.xsd
http\://www.springframework.org/schema/beans/spring-beans-2.5.xsd=org/springframework/beans/factory/xml/spring-beans-2.5.xsd

将此jar添加到您的依赖项：

<dependency>
     <groupId>org.springframework</groupId>
     <artifactId>spring-beans</artifactId>
     <version>3.1.2.RELEASE</version>
 </dependency>

现在您有了不同的JAR（

Springbeans

，

SpringTX

，

SpringAOP

，

SpringContext

…），它们都包含一个具有不同内容的

META-INF/spring.schemas

文件。另一方面，您可以使用

maven assembly plugin

将所有jar文件的内容聚合到一个jar文件中

我想您在

spring.handlers

文件中也会遇到这个问题

看起来您可以配置

maven汇编插件来合并这些文件。见：当然

另一种解决方案是使用
springbootmaven插件
，而不是
maven汇编插件

 <plugin>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-maven-plugin</artifactId>
     <version>1.2.1</version>
     <executions>
        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <mainClass>YOUR.MAIN.CLASS</mainClass>
    </configuration>
 </plugin>


org.springframework.boot
springbootmaven插件

（或者使用
maven shade插件
）
我遇到了与maven shade插件类似的问题。我的案例中的解决方案包含在

基本上，您必须在pom.xml中向maven shade插件配置中添加一个。从下面添加2个附加变压器条目：

<configuration>
    <outputDirectory>${basedir}/bin</outputDirectory>
    <finalName>myName</finalName>
    <transformers>
        <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
            <mainClass>com.foo.MyApp</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>
...
</configuration>


${basedir}/bin
我的名字
com.foo.MyApp
META-INF/spring.handlers
META-INF/spring.schemas
...
你能试着从xsd导入中删除版本号吗？当我删除它们时，这是相同的错误消息。我添加了更改，但有相同的错误消息。我认为maven汇编插件是关键谢谢，是的，这是问题所在，所以我使用了maven shade插件。这是教程页面的链接，谢谢。对我来说，它在使用SpringBootMaven插件而不是maven汇编插件时工作
