使用maven, myeclipse工具構建spring mvc項目

一.使用myeclipse 建立一個新的 maven項目.html

  (ps:1.在filter過濾的時候輸入 webapp 選擇"maven-archetype-webapp". 2.在main下建一個java文件夾(建source folder可能不能成功))前端

  具體可參考:http://www.cnblogs.com/waniu/p/3798775.htmljava

 

二.將project 轉變成webproject.(右鍵--properties--myeclipse--project facets-->勾選"dynamic web module")(若是已是web 可省去此操做.)web

 

三.爲project賦予spring mvc的特性.spring

  在WEB-INF目錄下創建:applicationContext.xml,**-servlet.xml而且配置web.xml三個文件.分別爲apache

  web.xmlspring-mvc

web.xml
<?
xml version="1.0" encoding="UTF-8"?> <web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">   <!--listener裏邊配置的是,表示項目啓動時候會去讀取applicationContext.xml,去實例化bean--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <servlet> <servlet-name>exam</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>exam</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>

  啓動時會默認在/WEB-INF目錄下查找applicationContext.xml做爲spring容器的配置文件,這裏能夠初始化一些bean,如DataSource。咱們這裏什麼也不作。代碼以下:applicationContext.xml(暫時不配置具體bean)服務器


<?
xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans> </beans>

啓動時也會默認在/WEB-INF目錄下查找XXX-servlet.xml做爲配置文件,XXX就是DispatcherServlet的名字,該文件中將配置兩項重要的mvc特性:mvc

HandlerMapping,負責爲DispatcherServlet這個前端控制器的請求查找Controller;app

ViewResolver,負責爲DispatcherServlet查找ModelAndView的視圖解析器。

<?xml version="1.0" encoding="UTF-8"?>
<!-- Bean頭部 -->
<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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:util="http://www.springframework.org/schema/util"
    xsi:schemaLocation="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  
            http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd              
            http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd">
    
    <!-- 激活@Controller模式 -->
    <mvc:annotation-driven />
    <!-- 對包中的全部類進行掃描,以完成Bean建立和自動依賴注入的功能 須要更改 -->
    <context:component-scan base-package="cc.monggo.web.controller" />

    <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WEB-INF/jsp/</value>
        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>
    </bean>
</beans>

 

四: 配置pom.xml,讓maven解決jar包依賴問題

pom.xml:

pop.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>exam</groupId>
  <artifactId>exam_3</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>exam_3 Maven Webapp</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
    
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
        <version>3.0.5.RELEASE</version>
    </dependency>
    
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
        <version>3.0.5.RELEASE</version>
    </dependency>
    
    <dependency>
        <groupId>org.apache.geronimo.specs</groupId>
        <artifactId>geronimo-servlet_2.5_spec</artifactId>
        <version>1.2</version>
    </dependency>
            
  </dependencies>
  <build>
    <finalName>exam_3</finalName>
  </build>
</project>

 

 

這樣一個最基本spring mvc項目就配置好了

 

此時對於實現部署測試過的項目啓動時候可能會引起:

嚴重: Error configuring application listener of class org.springframework.web.context.ContextLoaderListener 

從新部署服務器,試試應該就能夠了.

 

五: 打包部署:

  maven項目打包很容易,直接右鍵項目 run as --maven install 就會在 target目錄下構建 ***.war 部署包,將部署包放入到應用服務器下,便可完成部署運行.
