使用 xml 使用 spring mvc 配置 mongodb

Question

我正在尝试使用 xml 文件使用 spring mvc 配置 mongodb。 我收到此错误请帮我解决此错误

抛出的异常：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mongoTemplate' defined in ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml]: Cannot resolve reference to bean 'mongoDbFactory' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'mongoDbFactory' available

根据各种教程，这是我的 Spring 配置 XML：

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:mongo="http://www.springframework.org/schema/data/mongo"
    xmlns:beans="http://www.springframework.org/schema/beans"

<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <beans:property name="prefix" value="/WEB-INF/views/" />
        <beans:property name="suffix" value=".jsp" />
    </beans:bean>

    <context:component-scan base-package="com.excelit.signup" />

    <mongo:mongo id="mongo" host="localhost" port="27017" />

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

例外是说 mongoDBFactory 没有 bean。

尝试在 mongo 命名空间中添加工厂和客户端 bean...

<mongo:mongo-client id="mongoClient" host="localhost" />
<mongo:db-factory id="mongoDbFactory" dbname="test" mongo-client-ref="mongoClient" />
