<!-- Factory bean that creates the Mongo instance
-->
<bean id="mongo" class="org.springframework.data.mongodb.core.MongoFactoryBean">
<property name="host" value="localhost" />
<property name="port" value="27017" />
</bean>
<bean id="grouponTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg name="mongo" ref="mongo" />
<constructor-arg name="databaseName" value="groupon3" />
</bean>
<bean id="sequenceTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg name="mongo" ref="mongo" />
<constructor-arg name="databaseName" value="sequences3" />
</bean>
执行打好的jar包后,报如下错误:
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.
我的想法是通过上面的jar树和配置文件,证明我已经依赖了spring-data-mongodb包。
那为什么仍然会提示我MongoTemplate没有定义?
感谢@Kavlez同学提醒和@XFHNever同学帮忙,的确是没有加载到配置文件,给入口类添加@ImportResource("applicationContext.xml")
加载成功后,又报NoUniqueBeanDefinitionException异常,描述为
No qualifying bean of type [org.springframework.data.mongodb.core.MongoTemplate] is defined: expected single matching bean but found 2: sequenceTemplate,grouponTemplate
但此时我注入的方式是@Autowired和@Qualifier("grouponTemplate")配合(在其他spring项目中这样做没有问题的)但为什么仍然会报NoUniqueBeanDefinitionException呢?
好吧,问题的原因没有找到,倒是让我侥幸解决了:
在spring配置文件中新添加了一个bean:
<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg name="mongo" ref="mongo" />
<constructor-arg name="databaseName" value="test" />
</bean>
项目跑了起来~
最后,如果有幸得知该问题的原因,我更新在这个问题下面。再次感谢。
D'après les informations fournies par le sujet, aucun des deux MongoTemplates déclarés dans le fichier de configuration Spring n'a été détecté.
.Si, comme @XFHNever l'a dit, c'est parce que deux beans du même type sont configurés en même temps et qu'il est impossible d'identifier lequel est
Autowire
Dans ce cas, le message d'exception devrait être :Je suppose que le fichier de configuration n'a peut-être pas été lu.
Cela peut être dû au fait que vous avez configuré deux MongoTemplates dans le fichier de configuration et que Spring ne sait pas lequel doit être chargé. Vous pouvez envisager d'utiliser @Autowired et @Qualifier en même temps pour spécifier quel MongoTemplate charger.
