Java代码

- 注意:url-pattern的配置为‘/’。
- (2)配置applicationContext.xml
Java代码

<!-- Activates various annotations to be detected in bean classes -->
<context:annotation-config />
<!-- Scans the classpath

annotated components that will be auto-registered as Spring beans.For example
@Controller

<context:component-scan base-

/>
<context:component-scan base-

=
"bgi.service"

<!-- Configures the annotation-driven Spring MVC Controller programming model.Note that, with Spring

,

tag works in Servlet MVC only! -->
<mvc:annotation-driven />
<!-- Loads MongoDB configuraton -->
<
import
resource=
"mongo-config.xml"
/>
</beans>
(3)配置mongo-config.xml
Java代码
- ?1234567891011121314151617181920
<?xml version=
"1.0"
encoding=
"UTF-8"
?>

xmlns:p=

xsi:schemaLocation="http:

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

http:
//www.springframework.org/schema/data/mongo/spring-mongo.xsd">
<!-- Default bean name is

-->
<mongo:mongo host=

port=

/>
<!-- 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
- ?123456789101112
<?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">
<!-- Declare a view resolver -->
<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。
