Question

我在rest，spring，cxf和tomcat中做了一个web服务。

我在bean上遇到了这个错误。无法弄清楚为什么会这样？

SEVERE: Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'restContainer': Cannot resolve reference to bean 'timeService' while setting bean property 'serviceBeans' with key [0]; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'timeService' is defined at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference(BeanDefinitionValueResolver.java:328) at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveValueIfNecessary(BeanDefinitionValueResolver.java:106)

timeService.java

@Service("timeService")  
@Path("/time")  
public class TimeService {

    @GET
    @Produces("text/plain")
    public String getDateTime()
    {
        DateFormatter formatter = new DateFormatter("dd/MM/yyyy hh:mm:ss");
        return formatter.print(Calendar.getInstance().getTime(), Locale.getDefault());
    }
}

的beans.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">

    <import resource="classpath:META-INF/cxf/cxf.xml"/>
    <import resource="classpath:META-INF/cxf/cxf-extension-jaxrs-binding.xml"/>
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>

    <jaxrs:server id="restContainer" address="/">
        <jaxrs:serviceBeans>
            <ref bean="timeService"/>
        </jaxrs:serviceBeans>
    </jaxrs:server>

</beans>

这些是我的文件，我无法找出问题所在。这让我疯了！

Spring documentation表示您需要添加一个元素来指导查找@Service - 带注释的bean。例如，如果您的bean位于包org.example或其中一个子包中，那么您将在beans.xml中使用组件扫描程序配置，如下所示：

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

（只要它位于<beans>元素内，无论它是高于还是低于<jaxrs:server>元素，都可以。）
