注入自动布线依赖失败

我在Java-EE应用程序中使用Spring和Hibernate。该项目托管在this GitHub repository。注入自动布线依赖失败

package no.niths.rest; 

// Imports ... 

@Controller 
@RequestMapping("courses") 
public class CourseController implements SimpleREST<Course>{ 

    @Autowired 
    public CourseService service; 
}

而且respectice服务：

package no.niths.services; 

// Imports ... 

@Service 
public class CourseService { 

    @Autowired 
    public ICourse repo; 
}

最后我app-config.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" 
    xsi:schemaLocation=" 
     http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
     http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 

    <bean id="propertyConfigurer" 
     class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> 
     <property name="locations"> 
      <list> 
       <value>/configuration.properties</value> 
       </list> 
     </property> 
    </bean> 
    <context:annotation-config /> 
    <context:component-scan base-package="no.niths.services"/> 
    <context:component-scan base-package="no.niths.rest"/> 
    <context:component-scan base-package="no.niths.infrastructure"/> 
    <context:component-scan base-package="no.niths.infrastructure.interfaces"/> 
    <context:component-scan base-package="no.niths.domain"/> 


    <import resource="db-config.xml" /> 
</beans>

和错误我使用有问题'，通过服务这样@Autowired部署时抛出的是：

这里是更新的堆栈跟踪：

是什么原因造成这一点，什么问题该自动装配？

您的代码没有正确编译，因为错误提示。如果你不能先编译它，那么没有必要部署应用程序。 – skaffman

为什么不先编译你的代码？不知道我理解那里的思考过程。 – AHungerArtist

@skaffman我使用Eclipse提供了某种持续集成功能，因此在Maven构建它之后它会尝试部署它（到SpringFabric服务器）。 – whirlwin

的问题是不是在控制器或任何东西，但在我使用SessionFactory和@Autowired的一些存储库类中。

我也遇到了与“SessionFactory”相同的问题，解决方案是什么？ – vissu

@vissupepala对不起，真的很晚回复，但我其实不确定。不幸的是，这个问题很少记录。 – whirlwin

确保spring-beans.jar位于您的应用程序类路径中。

Maven中你可以使用“MVN依赖：树”，看看这罐子是作为依赖
当你的项目建设（WAR我相信）确保罐子是在WEB-INF/lib目录

是的，它在那里。 – whirlwin

Windows还是Unix？在Unix上检查打开文件的最大数量限制（ulimit命令） – maximdim

* nix，它表示“unlimited”。 – whirlwin

添加的Spring Bean的依赖，它包含了org.springframework.beans.factory.annotation.Autowired注释类：

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-beans</artifactId> 
    <version>3.1.0.RELEASE</version> 
</dependency>

注解已经可用了，我们已经在一些单元测试中使用它了，但是好的建议。 – whirlwin

检查spring-beans JAR是否位于WAR的WEB-INF/lib文件夹中。 –

是的，我发现它：'WEB-INF/lib/spring-beans-3.1.0.RELEASE.jar'。 – whirlwin
