Question

我创建了一个类似于this的应用程序，但是我得到了一个由org.springframework.beans.factory.NoSuchBeanDefinitionException引起的java.lang.reflect.InvocationTargetException。

我的.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"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:util="http://www.springframework.org/schema/util"
       xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.5.xsd">

    <context:component-scan base-package="my.package" />

    <util:map id="multiWordTermModels">
        <entry key="termList_wiki" value="resources/multiWordTerms.lst"/>
    </util:map>

</beans>

我的java应用程序：

package my.package;

public class ModelLoader {

    private static Map<String, String> multiWordTermModels;

    public static void loadModels() throws IOException, ClassNotFoundException{
        ApplicationContext appContext = new ClassPathXmlApplicationContext("classpath*:**/resources/application-context.xml");
        Beans beans = appContext.getBean(Beans.class);
        multiWordTermModels = beans.getMultiWordTermModel();
    }
}

豆类：

package my.package;

@Service
public class Beans {

    @Resource(name="multiWordTermModels")
    private Map<String, String> multiWordTermModels;

    public Map<String, String> getMultiWordTermModel(){
        return multiWordTermModels;
    }
}

它与示例中的相同，所以我不知道问题是什么。

编辑：完成堆栈跟踪：

所以问题只是不正确的Application-Context参数 classpath*:**/resources/application-context.xml 我必须用application-context.xml替换，这个xml文件应位于此处：

/项目-DIR
| _ / src
| _ /主
| _ /资源
| _Application-context.xml中

Spring util：地图注入
