Question

我在同一台机器上运行MongoDb和Spring MVC应用程序。出于某种原因，我在尝试通过Spring MVC应用程序访问数据时遇到了读取操作错误。

以下是Spring中app.xml上的配置：

    <!-- Mongo DB Conf -->
<bean id="mongo" class="org.springframework.data.mongodb.core.MongoFactoryBean">
    <property name="host" value="192.168.1.79"></property>
    <property name="port" value="28017"></property>
</bean>

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

提前感谢任何输入。

Answer 1

MongoDB服务器启动的常用端口是27017，您正在使用28017.尝试将其更改为27017并查看是否对您有帮助。

试试这个。

options.connectionsPerHost = 100;
options.maxWaitTime = 2000;
options.socketKeepAlive = true;
options.threadsAllowedToBlockForConnectionMultiplier = 50;

如果你使用spring模板，只需配置如下：

<mongo:mongo host="${mongodb.server}" port="${mongodb.port}">
    <mongo:options  
      connections-per-host="${mongo.connectionsPerHost}"  
      threads-allowed-to-block-for-connection-    multiplier="${mongo.threadsAllowedToBlockForConnectionMultiplier}"  
         connect-timeout="${mongo.connectTimeout}"  
         max-wait-time="${mongo.maxWaitTime}"  
         auto-connect-retry="${mongo.autoConnectRetry}"  
         socket-keep-alive="${mongo.socketKeepAlive}"  
         socket-timeout="${mongo.socketTimeout}"     
/>
