Quickly create a spring MVC sample

1. Create a servlet project reference http://www.cnblogs.com/zno2/p/5908589.html

2. Introducing Spring MVC Dependency

        <Dependency>            <groupId>Org.springframework</groupId>            <Artifactid>Spring-webmvc</Artifactid>            <version>4.3.3.RELEASE</version>        </Dependency>

Note: When you create a spring bean configuration file in an STS, you can load the namespaces (update project as appropriate)

Such as

3. Modify Web. xml

<Web-appversion= "3.0"xmlns= "Http://java.sun.com/xml/ns/javaee"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation= "Http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">    <Display-name>Archetype Created Web Application</Display-name>    <Context-param>        <Param-name>Contextconfiglocation</Param-name>        <Param-value>/web-inf/root-context.xml</Param-value>    </Context-param>    <servlet>        <Servlet-name>Dispatcher</Servlet-name>        <Servlet-class>Org.springframework.web.servlet.DispatcherServlet</Servlet-class>        <Init-param>            <Param-name>Contextconfiglocation</Param-name>            <Param-value></Param-value>        </Init-param>        <Load-on-startup>1</Load-on-startup>    </servlet>    <servlet-mapping>        <Servlet-name>Dispatcher</Servlet-name>        <Url-pattern>/</Url-pattern>    </servlet-mapping>    <Listener>        <Listener-class>Org.springframework.web.context.ContextLoaderListener</Listener-class>    </Listener></Web-app>

Ps:url-pattern must be '/' cannot be '/* '

4. Create Web-inf/root-context.xml

<?XML version= "1.0" encoding= "UTF-8"?><Beansxmlns= "Http://www.springframework.org/schema/beans"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"Xmlns:mvc= "Http://www.springframework.org/schema/mvc"Xmlns:context= "Http://www.springframework.org/schema/context"xsi:schemalocation= "Http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd/HTTP Www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd " >    <Mvc:annotation-driven/>    <Context:component-scanBase-package= "Zmvc" />    <BeanID= "Viewresolver"class= "Org.springframework.web.servlet.view.UrlBasedViewResolver">        < Propertyname= "Viewclass"value= "Org.springframework.web.servlet.view.JstlView" />        < Propertyname= "prefix"value= "/web-inf/jsp/" />        < Propertyname= "suffix"value= ". jsp" />    </Bean></Beans>

Ps:base-package is used to scan the controller under the specified package

5. Writing a Controller

 Package Zmvc; Import Org.springframework.stereotype.Controller; Import org.springframework.web.bind.annotation.RequestMapping; @Controller  Public class Test {        = "/test")    public  String Test () {        return " TestResult ";    }}

6. Add View

Create web-inf/jsp/testresult.jsp

< HTML > < Body > < H2 > This is a test result! </ H2 > </ Body > </ HTML >

7. Turn on log

① adding dependencies

        <Dependency>            <groupId>Log4j</groupId>            <Artifactid>Log4j</Artifactid>            <version>1.2.14</version>        </Dependency>

② adding log4j.properties

# Root Logger optionlog4j.rootlogger=trace, file, stdout# Direct log messages to a log filelog4j.appender.file=org.apache. Log4j. Rollingfileappenderlog4j.appender.file.file=e:\\logging.loglog4j.appender.file.maxfilesize= 10mblog4j.appender.file.maxbackupindex=10log4j.appender.file.layout= Org.apache.log4j.patternlayoutlog4j.appender.file.layout.conversionpattern=%d{yyyy-mm-dd HH:mm:ss}%-5p%c{1}:%L- %m%n# Direct log messages to stdoutlog4j.appender.stdout= org.apache.log4j.consoleappenderlog4j.appender.stdout.target=system.outlog4j.appender.stdout.layout= Org.apache.log4j.patternlayoutlog4j.appender.stdout.layout.conversionpattern=%d{yyyy-mm-dd HH:mm:ss}%-5p%c{1}:% L-%m%n

8. Complementary dependencies

Test needs to use JSTL to add the following dependencies

        <Dependency>            <groupId>Javax.servlet</groupId>            <Artifactid>Jstl</Artifactid>            <version>1.2</version>        </Dependency>

9. Final directory structure
