java.lang.NoClassDefFoundError : org/springframework/context/support/ClassPathXmlApplicationContext 错误

Question

我在我的 Jar 文件中使用 Spring 从属性文件中获取属性。当我尝试从我的 RAD(eclipse) 中获取输出时。但是当我在服务器中部署我的 jar 文件时，我不断收到此错误。我是否需要包含任何其他 XML 文件？

获取应用程序上下文时发生错误。

ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

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:p="http://www.springframework.org/schema/p"
       xmlns:jee="http://www.springframework.org/schema/jee"
       xmlns:util="http://www.springframework.org/schema/util"
       xsi:schemaLocation="http://www.springframework.org/schema/util http://xml.westfieldgrp.com/public/schema/util/spring-util-3.0.xsd
                           http://www.springframework.org/schema/beans http://xml.westfieldgrp.com/public/schema/beans/spring-beans-3.0.xsd 
                           http://www.springframework.org/schema/jee http://xml.westfieldgrp.com/public/schema/jee/spring-jee-3.0.xsd" >    
    <bean id="applicationProperties" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:/config/devint/nimo.properties"/>
    </bean>  
    <bean id="nimoConfigurationBean" scope="singleton"
        class="com.westfieldgrp.filenet.env.NimoConfigurationBean">
        <property name="serviceUser" value="${env.user}" />
        <property name="servicePass" value="${env.pass}" />
    </bean> 
</beans>

用 Java 调用:

public class AddEnvProperty {

    public String envType(String propertyValue) {   
        String returnValue = "";

        AddEnvProperty envProps = new AddEnvProperty();
        NimoConfigurationBean nimoConfigurationBean = envProps.getConfig();

        PluginLogger logger = new PluginLogger(new ResponceFilterPlugin());
        logger.logDebug(this, "envType", "Getting Property Value" + propertyValue);
        try {

             if (propertyValue == "USER") {
                returnValue = nimoConfigurationBean.getServiceUser();
            } else if (propertyValue == "PASS") {
                returnValue = nimoConfigurationBean.getServicePass();
            }

        } catch (NullPointerException ex) {
            logger.logError(this, "envType", "NullPointerException:", ex);
        }catch (Exception ex) {
            logger.logError(this, "envType", "NullPointerException:", ex);
        }
        return returnValue;
    }

    private NimoConfigurationBean getConfig() {
        ApplicationContext context = 
            new ClassPathXmlApplicationContext("applicationContext.xml");

        NimoConfigurationBean obj = (NimoConfigurationBean) context.getBean("nimoConfigurationBean");
        return obj;
    }
}

NimoConfigurationBean.java 中的 getter、setter 方法

检查您的 pom 文件中是否有该依赖项:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>x.x.x.RELEASE</version>
</dependency>

(x.x.x : 待修改)

如果你没有使用 maven :将 jar“spring-context-x.x.x.RELEASE.jar”检查到您的构建路径中
