NoSuchBeanDefinition儘管在XML bean定義

我做了以下注射：NoSuchBeanDefinition儘管在XML bean定義

@Inject 
private MongoTemplate mongoTemplate;

而且我已經在我的上下文以下XML負載：

<?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" 
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jee="http://www.springframework.org/schema/jee" 
    xmlns:mongo="http://www.springframework.org/schema/data/mongo" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd 
     http://www.springframework.org/schema/context

     http://www.springframework.org/schema/tx 
     http://www.springframework.org/schema/tx/spring-tx.xsd 
     http://www.springframework.org/schema/jee 
     http://www.springframework.org/schema/jee/spring-jee.xsd 
     http://www.springframework.org/schema/data/mongo 
     http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd"> 

    <tx:annotation-driven /> 

    <context:component-scan 
     base-package="mypackage.impl, mypackage.impl" /> 

    <mongo:mongo host="127.0.0.1" port="27017" /> 
    <mongo:db-factory dbname="test" /> 

    <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate"> 
     <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" /> 
    </bean> 

</beans>

而且我發現了以下堆棧跟蹤：

其中相關的位似乎是：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.data.mongodb.core.MongoTemplate] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@javax.inject.Inject()}

似乎很清楚要定義，爲什麼我變得不確定？

在哪個包中是帶'@ Inject'的類？ –

爲什麼你定義了'mypackage.impl，mypackage.impl'兩次？檢查是否指定了所需的軟件包。 – Keerthivasan

我只是掩蓋了我的組織。指定了所需的軟件包。 – Lurk21

我最終只是這樣做：

ApplicationContext ctx = new GenericXmlApplicationContext("SpringConfig.xml"); 
MongoOperations mongoOperation = (MongoOperations) ctx.getBean("mongoTemplate");

說不上來爲什麼我不能把它注射...

沒有太多的去這裏，但我想到的一件事是，如果你正在嘗試@Inject創建一個新的類，比注入將無法工作。它只會在由Spring容器管理的類中工作。

只是個人喜好：我不是春天的xml配置的大粉絲，在某些情況下，它可以完全避免使用基於註釋的配置。
