Controller / Servlet在ServiceAPI上抛出NoClassDefFoundError

时间：2015-07-29 14:41:06

标签： java spring web-services controller noclassdeffounderror

我有一个Spring项目，其中包含我服务的所有部分（Controller，API和ServiceImpl）。现在我试图将控制器从休息状态中分离出来。

现在我有两个项目：

  • X-Service（API，Impl）
  • X-Controller（控制器）

在我的控制器中，我使用

自动装配我的API 
public class XController {

    @Autowired
    XServiceApi service;

Maven安装适用于两个项目但是当我在tomcat6上启动我的webapp时出现以下错误：

  1. 所有需要的类都可以嵌套在我的controller.war
    2. 的service.jar中

  2. 这是我的AppConfig：

    @Configuration @ComponentScan（＆＃34; de.adclear.soa.integration.xservice＆＃34） @PropertySource（{＆＃34; http://localhost:8080/x-svc/ $ {config.context：staging} .properties＆＃34;}） 公共类ApplicationConfig {

    @Value("${mongo.uri}")
private String  uri;

@Value("${mongo.dbname}")
private String  databaseName;

// To resolve ${} in @Value
@Bean
public static PropertySourcesPlaceholderConfigurer propertyConfigInDev() {
    return new PropertySourcesPlaceholderConfigurer();
}

@Bean
public MongoOperations mongoOperations() throws NumberFormatException, UnknownHostException {
    return (MongoOperations) new MongoTemplate(mongoDBFactory());
}

@Bean
public MongoDbFactory mongoDBFactory() throws NumberFormatException, UnknownHostException {
    return new SimpleMongoDbFactory(mongoClient(), databaseName);
}

@Bean
public MongoClient mongoClient() throws UnknownHostException {
    return new MongoClient(new MongoClientURI(uri));
}

    3. 因为我不知道programmitacally如何设置web.xml和我的调度程序我也有这个3 xml文件：

    的web.xml：

    <?xml ...
        "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
    <servlet>
        <servlet-name>ckm-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>x-dispatcher</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>

</web-app>

    x-dispatcher-servlet.xml：

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc" 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-4.0.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-4.0.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

    <import resource="classpath:x-service-context.xml" />
</beans>

    的x服务context.xml中：

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=...
        http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

    <!-- Activate Annotation driven configuration for mvc to enable automatic jackson mapping --> 
    <mvc:annotation-driven />

    <!-- Activate Annotation based configuration -->
    <context:annotation-config />

    <!-- Defines where to search for annotated components -->
    <context:component-scan base-package="de.adclear.soa.integration.xservice" />
</beans>

2 个答案:

答案 0 :(得分：0)

看看jar，如果该类实际存在于那里。 从路径de/adclear/soa/integration/test/开始，您似乎已将其放入测试文件夹中，默认情况下从jar / war中排除。

答案 1 :(得分：0)

这不是答案，而是解决方案。问题出在tomcat6的eclipse插件中。如果我用tomcat6的maven插件运行相同的项目，它可以正常工作！
