1.3 配置

（1）配置Web.xml

Java代码收藏代码

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

<display-name>TestSpringMongodb</display-name>

<!— spring mvc dispatcher servlet -->

<servlet>

<servlet-name>spring</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>spring</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

</web-app>

注意：url-pattern的配置为‘/’。

（2）配置applicationContext.xml

Java代码收藏代码

<?xml version="1.0" encoding="UTF-8"?>

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

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

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

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

xsi:schemaLocation="http://www.springframework.org/schema/mvc

http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

<context:annotation-config />

<context:component-scan base-package="bgi.contrl" />

<context:component-scan base-package="bgi.service" />

<mvc:annotation-driven />

<import resource="mongo-config.xml"/>

</beans>

（3）配置mongo-config.xml

Java代码收藏代码

<?xml version="1.0" encoding="UTF-8"?>

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

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

xmlns:mongo="http://www.springframework.org/schema/data/mongo"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/data/mongo

http://www.springframework.org/schema/data/mongo/spring-mongo.xsd">

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

<!-- Offers convenience methods and automatic mapping between MongoDB JSON documents and your domain classes. -->

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">

<constructor-arg ref="mongo"/>

<constructor-arg name="databaseName" value=http://www.mamicode.com/"test"/>

</bean>

</beans>

注意：官方文档和案例配置都是旧版本的配置案例，spring-data-mongo从1.0.0.M1到1.0.0.M3的版本叫做Spring Data Document。1.0.0.M4开始更名为Spring Data MongoDB 1.0.0 M4，不过官网并没有特别说明，乍一看有点莫名其妙，尤其是MongoTemplate从org.springframework.data.document.mongod移动到org.springframework.data.mongodb.core，官网的HelloWorldExample却还是用org.springframework.data.document.mongodb做配置案例。多少会导致使用时的误导。

（4）配置spring-servlet.xml

Java代码收藏代码

<?xml version="1.0" encoding="UTF-8"?>

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

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"

p:prefix="/" p:suffix=".jsp" />

</beans>

注意：spring-servlet.xml的命名是根据web.xml中配置spring DispatcherServlet的名字（<servlet-name>spring</servlet-name>）加上-servlet命名的。

}

/**

*

* @param name

* @return

*/

public User findUserByName(String name){

return mongoTemplate.findOne(new Query(Criteria.where("name").is(name)), User.class, USER_COLLECTION);

}

Java代码收藏代码

package bgi.pojo;

}

@Override

public String toString() {
