maven+Spring簡單web專案demo
阿新 • • 發佈:2019-02-10
1.右鍵新建專案(沒有maven專案時,點選other),如下圖所示,選擇Maven Progect
2.設定專案儲存位置
3.選擇maven-archetype-webapp
4、輸入專案組id和本專案id,點選finish完成
5、專案完成後,右鍵專案屬性properties,選擇deploymentAssembly,將不需要釋出的目錄remove移除掉
6、最終專案目錄如下所示
7、修改maven的pom.xml檔案,增加jar包的依賴描述,maven會自動下載相關jar包及其依賴包
<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_2</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>Maven Webapp Archetype</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>3.0.7.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>3.0.7.RELEASE</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.4</version> <scope>provided</scope> </dependency> </dependencies> <build> <finalName>exam_2</finalName> </build> </project>
8、修改web.xml,配置spring和servlet
<?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"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:conf/applicationContext.xml</param-value> </context-param> <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> <init-param> <param-name>exam</param-name> <!-- 預設路徑在WebConte下面,預設名稱就是spring-servlet.xml,我們這裡就不使用預設值 --> <param-value>classpath:conf/exam-servlet.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>exam</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> </web-app>
9、資原始檔applicationContext.xml,因為我們只是簡單的使用spring,暫時沒有配其他的,但也要有該檔案,內容可以不填,基本的如下
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
</beans>
10、exam-servlet.xml配置對servlet的處理,檔案內容如下
<?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"> <!-- 啟用@Controller模式 --> <mvc:annotation-driven /> <!-- 對包中的所有類進行掃描,以完成Bean建立和自動依賴注入的功能 需要更改 --> <context:component-scan base-package="com.xiaoma.action" /> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix"><!-- 檢視檔案的字首 --> <value>/WEB-INF/jsp/</value> </property> <property name="suffix"><!-- 檢視檔案的字尾 --> <value>.jsp</value> </property> </bean> </beans>
11、現在我們可以新建一個action來測試一下,我們的spring是否可以正常使用,根據之前的字首及字尾配置,我們在WEB-INF下新建jsp/demo目錄,在demo目錄下新建 demo.jsp頁面
新建包com.xiaoma.action,在該包下新建TestAction.java類,
package com.xiaoma.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class TestAction {
@RequestMapping("/test.do")
public ModelAndView test(HttpServletRequest request,HttpServletResponse response){
System.out.println("1234");
return new ModelAndView("/demo/demo","message","abc");
}
}
訪問test.do 時,即可返回demo.jsp頁面,並將message物件帶過去
