  您的开始和结束标记不匹配，您忘了定义 beans 名称空间：

  <?xml version="1.0" encoding="UTF-8"?>
  <beans:bean ...>
         ^^^^ opening tag => bean
  ...    
  </beans:beans>
      |   ^^^^^ ending tag => beans
      |
      + =====> Where did you define beans namespace?
  

  所以，用以下代替第一行：

  <beans:beans xmlns:beans="http://www.springframework.org/schema/beans"
  

  另外，将 mvc 名称空间添加为默认名称空间：

  xmlns="http://www.springframework.org/schema/mvc"
  

  你的 servlet-context.xml 最终看起来像这样：

  <?xml version="1.0" encoding="UTF-8"?>
  <beans:beans xmlns:beans="http://www.springframework.org/schema/beans"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
               xmlns:context="http://www.springframework.org/schema/context"
               xmlns:mongo="http://www.springframework.org/schema/data/mongo"
               xmlns="http://www.springframework.org/schema/mvc"
               xsi:schemaLocation="http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-3.0.xsd
            http://www.springframework.org/schema/data/mongo
            http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd
            http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
            http://www.springframework.org/schema/mvc
            http://www.springframework.org/schema/mvc/spring-mvc.xsd">
  
  
      <!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->
  
      <!-- Enables the Spring MVC @Controller programming model -->
      <annotation-driven />
  
      <!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
      <resources mapping="/resources/**" location="/resources/" />
  
      <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
      <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.etvld.mvc" />
  
      <mongo:mongo host="192.168.1.19" port="27017"/>
  
  </beans:beans>
  

  如果您发现自己使用Spring配置会感到不舒服，我猜你会这样做，最好切换到 Spring Boot ，它会自动完成大部分这类配置 .

  这是一个简单的mongo配置

  @Configuration
  public class SpringConfig {
  
      @Bean
      public MongoDbFactory mongoDbFactory() throws UnknownHostException{
          return new SimpleMongoDbFactory(new MongoClient(),"games");
      }
  
      @Bean
      public MongoTemplate mongoTemplate() throws UnknownHostException{
          MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory());      
          return mongoTemplate;
      }
  
  }
  

  它使用注释，但它与你只是@Autowire mongoTemplate相同 .

  转换为xml，这看起来与此类似或相等

  <beans:bean id="mongoClient" class="com.mongodb.MongoClient">
      </beans:bean>
  
  <beans:bean id="mongoDbFactory" class="org.springframework.data.mongodb.core.SimpleMongoDbFactory">
        <constructor-arg ref="mongoClient"/>
        <constructor-arg type="java.lang.String" value="dbName"/>
     </beans:bean>
  
  <beans:bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg ref="mongoDbFactory"/>
  
     </beans:bean>
  

  没有在xml上测试过，所以我可能会遗漏一些东西，

  哦，正如另一个答案所指出的那样，你应该 <beans:bean ..... 它应该是 <beans:bean ..... 并且恰当地关闭 </beans:bean>

  希望能帮助到你
