虽然我看到很多问题,但有些答案与我的设置无关。 我总共有3个模块API,Impl和consumer。消费者依赖API和Impl。消费者有web.xml,看起来像
<web-app>
<display-name>Archetype Created Web Application</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath*:/**/conf/spring-config.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>com.name.TestMe</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</webapp>
在消费者资源conf / spring-config.xml中存在配置
<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"
xsi:schemaLocation="http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.1.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.1.xsd">
<import resource="classpath*:/**/repository.xml"/>
</beans>
在repository.xml中我有
<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/context
http://www.springframework.org/schema/context/spring-context-4.1.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:/**/properties/mongo-config.properties
</value>
</list>
</property>
</bean>
<!-- <import resource="config/mongo-core.xml" /> -->
<import resource="config/spring-core.xml" />
</beans>
我在这里遗漏了什么吗?
整个堆栈跟踪如下
java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 'refresh' before accessing beans via the ApplicationContext
at org.springframework.context.support.AbstractRefreshableApplicationContext.getBeanFactory(AbstractRefreshableApplicationContext.java:170)
at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:956)

at javax.servlet.http.HttpServlet.service(HttpServlet.java:618)
答案 0 :(得分:0)
Oups,你永远不应该写像
这样的东西ApplicationContext context = new ClassPathXmlApplicationContext();
mongoRepository = (MongoRepository)context.getBean("mongoRepositoryImpl");
正如你在上次评论中所展示的那样!您创建一个新的空的未初始化的应用程序上下文,而不是使用spring ContextLoaderListener
创建的那个。
Spring允许您自动或显式地连接bean,但是您自己的类不应该直接访问应用程序上下文,除非是非常特殊的用例。它应该足够写(只是一个猜测,因为我不知道你的配置,但它是一个例子):
@Autowired
MongoRepository mongoRepository;
如果配置中只包含一个MongoRepository
类型的bean,并且TestMe
也是一个spring bean,那么spring将自动连接它们。如果您有多个相同类型的bean,则可以使用@Qualifier
注释指定名称:
@Autowired
@Qualifier("mongoRepositoryImpl")
MongoRepository mongoRepository;
当然,您也可以在xml config中定义它。
