我尝试在不同的罐子中使用弹簧集成。 在a.jar文件的SI-context.xml中:弹簧集成:未找到网关bean

<context:annotation-config /> 
    <int:annotation-config /> 

    <int:channel id="upperServiceChannel"> 
     <int:priority-queue /> 
    </int:channel> 

    <int:gateway id="upperGateway" default-request-timeout="5000" 
     default-reply-timeout="5000" default-request-channel="upperServiceChannel" 
     service-interface="com.company.proj.gw.IUpperStringConversation"> 
     <int:method name="toUpperCase" /> 
    </int:gateway> 


    <bean id="toUpperCaseService" class="com.company.proj.service.ToUpperCaseService" /> 
    <int:service-activator id="serviceActivatorToUpperCase" 
     input-channel="upperServiceChannel" method="toUpperCase" ref="toUpperCaseService" /> 

    <int:poller id="poller" default="true" fixed-delay="1000" /> 
    <context:component-scan base-package="com.company"/> 

在一个bean我使用这个网关:

@Component(value = "upper") 
    public class UpperAdapter extends AAdapter<Message<String>> { 

    @Autowired 
    IUpperStringConversation gw; 

它的工作。问题是,如果我尝试从其他项目(B.jar)使用我的UpperAdapter。 B-context.xml中:

<import resource="classpath*:/*si-context.xml" /> 
<context:annotation-config /> 
<int:annotation-config /> 


    @Component(value="router") 
public class Router { 

    @Autowired 
    private Map<String, AAdapter<?>> adapters; 

在这里,我得到:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'upper': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: com.company.proj.gw.IUpperStringConversation com.company.proj.adapter.UpperAdapter.gw; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.company.proj.gw.IUpperStringConversation] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 

后,我设置的弹簧日志级别来调试,得到这样的信息:

DEBUG o.s.c.a.ClassPathBeanDefinitionScanner - Ignored because not a concrete top-level class: URL [jar:file:/home/tomto/Documents/workspace-sts/integration-fw/src/main/resources/META-INF/lib/integration-fw-module-string-0.0.1-SNAPSHOT.jar!/com/company/proj/gw/IUpperStringConversation.class] 

当然,这是真的,因为(也许我错了;))它将在春天在运行时生成的网关。

的IUpperStringConversation:

public interface IUpperStringConversation { 
    public String toUpperCase(String text); 
} 

我错过了什么?

Thx!

为'org.springframework'开启DEBUG日志记录;你会得到丰富的调试日志xml解析,bean发现/创建等。 –

你有没有解决过这个问题? – EoD

我们也有类似的问题,我们的网关并没有获得注入到我们的服务对象:

Project structure: 
---------------- 
-parent/ 
-common/ 
    --gateways defined here 
-module-a/ 
-module-b/ 

模块-B接收到异常信息是:

org.springframework.beans.factory.BeanCreationException: ... Injection of autowired dependencies failed 
... 
IllegalArgumentException: Class must not be null 

显然,问题正在由对模块-b类路径的冲突依赖造成。在我们清理了pom.xml中的Spring依赖关系后,它工作了!
