Springmvc+maven Frame Quick Build Step

Springmvc+maven Integration (Annotation form)

SPRINGMVC is the mainstream of the current framework, coupled with the form of annotations, greatly increased the efficiency of developers, and in the form of annotations, save a lot of XML configuration, so that the code seems to improve a lot of clarity.

The following teaches you how to configure, here to create the project is not introduced, we directly from the configuration of Pom.xml start.

The MAVEN coordinates used by the 1.SpringMVC

  <properties> <spring-version>3.1.0.RELEASE</spring-version> </properties> < dependencies> <!--Spring start--> <dependency> <groupid>org.springframework</group id> <artifactId>spring-web</artifactId> <version>${spring-version}</version> &L t;/dependency> <dependency> <groupId>org.springframework</groupId> <artifactid&gt      　　　　 ;spring-webmvc</artifactid> <version>${spring-version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactid>spring-jdbc</artifact id> <version>${spring-version}</version> </dependency> <dependency> <groupId> Org.springframework</groupid> <artifactId>spring-context</artifactId> <version>${spring- Version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactid>spring-aop</ar tifactid> <version>${spring-version}</version> </dependency> <dependency> <group Id>org.springframework</groupid> <artifactId>spring-core</artifactId> <version>${spri ng-version}</version> </dependency> <dependency> <groupid>org.springframework</groupid > <artifactId>spring-test</artifactId> <version>${spring-version}</version> &LT;/DEP        endency> <!--Spring start--> <!--log4j start--> <dependency> <groupid>log4j</groupid><artifactid>log4j</artifactid><version>1.2.16</ Version></dependency><dependency><groupid>org.slf4j</groupid><artifactid> slf4j-log4j12</artifactid><version>1.6.1</vErsion></dependency><dependency><groupid>org.slf4j</groupid><artifactid> slf4j-api</artifactid><version>1.6.1</version></dependency> <!--Log4j end--> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> < Version>1.2</version> </dependency> <!--jstl Tag Library--<dependency> &LT;GROUPID&G T;taglibs</groupid> <artifactId>standard</artifactId> <version>1.1.2</version> < /dependency> </dependencies>

The spring version chosen here is 3.1.0.RELEASE, and you can make the version according to your needs.

Configuration of the 2.web.xml

1<?xml version= "1.0" encoding= "UTF-8"?>2<web-app xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"3xmlns= "Http://java.sun.com/xml/ns/javaee" xmlns:web= "http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"4xsi:schemalocation= "Http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"5Id= "webapp_id" version= "3.0" >6     7<context-param>8<param-name>contextConfigLocation</param-name>9<!--Application Context profile--Ten<param-value>classpath:spring/spring-context.xml</param-value> One</context-param> A<listener> -<listener-class>org.springframework.web.context.contextloaderlistener</listener-class> -</listener> the      -<!--Configuring the spring core servlet-- -<servlet> -<servlet-name>daily-collect</servlet-name> +<servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class> -<init-param> +<description>spring MVC configuration file </description> A<param-name>contextConfigLocation</param-name> at<param-value>classpath:spring/spring-mvc.xml</param-value> -</init-param> -<load-on-startup>1</load-on-startup> -</servlet> -      -<listener> in<listener-class>org.springframework.web.util.log4jconfiglistener</listener-class> -</listener> to<context-param> +<param-name>log4jConfigLocation</param-name> -<param-value>classpath:log4j.properties</param-value> the</context-param> *      $<!--note here that the servlet-name must be the same as the name of the Servlet-name with the spring core configured above, which has a mapping relationship--Panax Notoginseng<!--Url-pattern is configured to/, without a file suffix, which can cause other static files (JS,CSS, etc.) to be inaccessible.

3.spring-context.xml configuration (Here are some globally used beans or load configuration files, referencing other spring XML).

1<beans xmlns= "Http://www.springframework.org/schema/beans"2xmlns:context= "Http://www.springframework.org/schema/context"3xmlns:p= "http://www.springframework.org/schema/p"4Xmlns:mvc= "Http://www.springframework.org/schema/mvc"5Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"6Xsi:schemalocation= "Http://www.springframework.org/schema/beans7http//www.springframework.org/schema/beans/spring-beans-3.0.xsd8http//Www.springframework.org/schema/context9http//www.springframework.org/schema/context/spring-context.xsdTenhttp//Www.springframework.org/schema/mvc Onehttp//www.springframework.org/schema/mvc/spring-mvc-3.0.xsd "> A<!--opening SPRINGMVC annotations-- -<context:annotation-config/> -     the<!--start the package scan feature to register classes with annotations such as @controller, @Service, @repository, @Component and so on as spring beans-- -<context:component-scan base- Package= "Com.code.daily.*.*.controller"/> -      -      +<!--<ImportResource= "Classpath:spring/spring-tx.xml"/>-- -</beans>

4.spring-mvc.xml configuration (mainly on the opening of annotations, need to scan the annotation interception operation) inside a few tags you can directly search Baidu, will have introduced its role.

<beans xmlns= "Http://www.springframework.org/schema/beans"Xmlns:context= "Http://www.springframework.org/schema/context"xmlns:p= "http://www.springframework.org/schema/p"Xmlns:mvc= "Http://www.springframework.org/schema/mvc"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation= "Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp//Www.springframework.org/schema/contexthttp//www.springframework.org/schema/context/spring-context.xsdhttp//Www.springframework.org/schema/mvchttp//www.springframework.org/schema/mvc/spring-mvc-3.0.xsd "><context:annotation-config/> <mvc:annotation-driven/> <mvc:default-servlet-handler/> <context:component-scan base- Package= "Com.code.daily.*.*.controller"/> <!--the path resolution of the steering page.

7. Project Structure
8. Mapping of Access Paths Web. XML (Daily-collect) +controller (/test) + (/fisttest) +.do
Http://localhost:8089/daily-collect/test/fistTest.do
9. Common sexual issues
If you have already checked the project, configured this listener in Web. XML, and can find this jar package, but still report the error, then this may be that Maven did not refer to the project at the time of deployment
Solution: Right-click the project to select Properties
Restart the test, you may also encounter some other problems, you can Baidu try to solve, or write the question below, there is time to reply to the answer
