mongodb spring 中的 authsource

Question

您好，我正在使用 Spring MVC 和 MongoDB。我想知道我必须在哪里提到参数 "Authsource=admin"。同时我无法在 mongoTemplate bean 中提供 mongoCredentials，它抛出 bean 创建异常。

下面是我的调度员-servlet.xml

<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:p="http://www.springframework.org/schema/p"
   xsi:schemaLocation="http://www.springframework.org/schema/beans 
   http://www.springframework.org/schema/beans/spring-beans-3.2.xsd 
   http://www.springframework.org/schema/context 
   http://www.springframework.org/schema/context/spring-context-3.2.xsd">


<bean id="mongo" class="org.springframework.data.mongodb.core.MongoFactoryBean">
    <property name="host" value="54.172.243.152" />
    <property name="port" value="27005" />
</bean>
<bean id="mongoCredentials" class="org.springframework.data.authentication.UserCredentials">
    <constructor-arg name="username" value="smynapati" />
    <constructor-arg name="password" value="smynapati" />
    <!-- <constructor-arg name="authSource" value="admin" /> -->
</bean>

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongo" ref="mongo" />
    <!-- <constructor-arg name="mongoCredentials" ref="mongoCredentials" /> -->
    <constructor-arg name="databaseName" value="test1" />
</bean>
<bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" /> 
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<context:component-scan base-package="com.userlogin"/>
<bean id="ViewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass"
        value="org.springframework.web.servlet.view.JstlView" />
    <property name="prefix" value="/WEB-INF/jsp/" />
    <property name="suffix" value=".jsp" />
</bean>

Answer 1

假设您使用的是 spring-data-mongodb 的 1.5.2.RELEASE 版本（我记得您之前的一个问题）并且凭据存储在 admin 数据库中，这些应该是您的 MongoDB 相关 beans 设置：

<bean id="mongo" class="org.springframework.data.mongodb.core.MongoFactoryBean">
    <property name="host" value="54.172.243.152" />
    <property name="port" value="27005" />
</bean>
<bean id="mongoCredentials" class="org.springframework.data.authentication.UserCredentials">
    <constructor-arg name="username" value="smynapati" />
    <constructor-arg name="password" value="smynapati" />
</bean>

这些都完好无损。接下来是：

<bean id="mongoDbFactory" class="org.springframework.data.mongodb.core.SimpleMongoDbFactory">
    <constructor-arg name="mongo" ref="mongo" />
    <constructor-arg name="databaseName" value="test1" />
    <constructor-arg name="credentials" ref="mongoCredentials" />
    <constructor-arg name="authenticationDatabaseName" value="admin" />
</bean>

模板终于来了：

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

请注意，为简单起见，您最好使用 mongo XML 命名空间。
