idea基于maven 创建SpringMVC项目

小咪咪 2022-05-13 03:34 229阅读 0赞

一、在idea中file--new--project；

二、选择maven之后勾选Create from archetype然后选择maven-archetype-webapp，点击next；如图所示

![70][]

三、填写GroupId和ArtifactId,可随意写，不过一般GroupId写自己项目中包结构的前两层，ArtifactId则和自己的项目名称一致最好，Version默认即可。完成之后点击next；

![70 1][]

四、配置maven  选择settings.xml配置文件位置和本地库位置；

![70 2][]

需要注意一下我这里添加一个属性值，如图弹窗所示，点右边的加号，name=archetypeCatalog value=internal。就是为了图创建maven项目快，具体原因可自行查询。

五、设置项目名称和存放路劲，点击finish；

![70 3][]

六、下面我们在pom.xml文件中添加我们所需要的依赖，因项目而异，自己需要哪个jar包就添加对应依赖就好；

等待相应的jar包下载完成之后，到这里即完成了创建maven项目--后面接着搭框架

七、添加框架支持；

首先右键点击项目名称，选择Add FrameworkSupport...

![70 4][]

然后再窗口中一次选择Spring和SpringMVC并勾选自动创建spring-config.xml;如图所示：

![70 5][]

点击ok之后我们发现在WEB-INF下面自动生成了两个配置文件；

![70 6][]

接下来完善自己的项目结构，首先创建一个java文件夹，并点击File--Project Structure，点击Moudles，找到刚才创建的java文件夹，选择Sources文件夹变成蓝色；

![70 7][]

其他的结构这里就不做详细介绍了，根据项目需要而定就可以了；

下面开始配置web.xml,我把我项目中的原样copy过来，各部分带有解释就不一一详解了；

<?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
             version="3.1">
    
        <display-name>Archetype Created Web Application</display-name>
    
        
        <welcome-file-list>
            <welcome-file>index.jsp</welcome-file>
        </welcome-file-list>
    
        
        <servlet>
            <servlet-name>springMVC</servlet-name>
            <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
            <init-param>
                
                <param-name>contextConfigLocation</param-name>
                <param-value>/WEB-INF/dispatcher-servlet.xml</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
            <async-supported>true</async-supported>
        </servlet>
        <servlet-mapping>
            <servlet-name>springMVC</servlet-name>
            <url-pattern>/</url-pattern>
        </servlet-mapping>
        
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/applicationContext.xml</param-value>
        </context-param>
        <listener>
            <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
    </web-app>

然后开始配置 dispatcher-servlet.xml

<?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:context="http://www.springframework.org/schema/context"
           xmlns:mvc="http://www.springframework.org/schema/mvc"
           xsi:schemaLocation="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.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
        
    
        
        <context:annotation-config/>
    
        
        <mvc:annotation-driven/>
    
        
        
        <mvc:resources mapping="/css/**" location="/WEB-INF/css/"/>
        <mvc:resources mapping="/js/**" location="/WEB-INF/js/"/>
        <mvc:resources mapping="/image/**" location="/WEB-INF/image/"/>
    
        
        
        <bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
            <property name="prefix" value="/WEB-INF/views/"/>
            <property name="suffix" value=".jsp"/>
            <property name="exposeContextBeansAsAttributes" value="true"/>
        </bean>
    
        
        <context:component-scan base-package="com.demo"/>
    </beans>

接下来配置applicationContext.xml

配置完成之后，到这里基于maven的springMVC框架项目就算搭建完成了；

下面装载tomcat并开始项目即可！
