使用idea基于maven创建SpringMVC项目

以你之姓@ 2022-01-20 01:49 220阅读 0赞

首先我们可以创建maven项目，`file-> new ->project->maven`

如果下载不较慢，可以添加属性`name: archetypeCatalog ,value: internal`可以加快下载速度

在选择自己的maven时。默认的下载存储位置是在C盘，可以打开配置文件更改为自己的下载位置：`<localRepository>E:\Program Files\apache-maven-3.6.1\repository_file</localRepository>`

项目创建完成后你会看到，其中java、resources和test文件夹没有就自己创建，

创建好了之后是灰色的,需要`选中相应的文件夹右键 选择Mark Directory as 点击相应的颜色即可`

打开pom.xml文件，添加各类依赖，将下面的代码复制到标签中（这些是我添加的依赖，做个参考），添加完成之后，等待maven将这些jar下载完毕，下载完成后，可以看到External Library下多了很多文件

之后添加springMVC框架，右击项目文件夹Demo，选择Add framework support  
![在这里插入图片描述][20190610150926927.png]  
将下图中的Spring和Spring下的Spring MVC都勾上，之前配置pom.xml文件时，已经自动下载了spring相关文件，所以这里就直接用之前下载好的就可以了，OK。（注意：点了Add framework support之后，在下图中有可能会找不到Spring，解决办法在下图的下方）  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQxMTU2OQ_size_16_color_FFFFFF_t_70 7]  
如果在Add framework support中找不到Spring，那是因为项目中可能已经存在Spring相关文件，但不一定是完善的。因此我们要将已经存在的Spring给删掉，重新添加，方法如下：

点击File，选择Project Structure，（**快捷键ctrl+shift+alt+s**）选择Facets，就会看到有一个Spring啦，右击它，点删除就行啦，然后再回到上面第3步重新Add framework support，Spring就会出现啦。

Spring框架添加完之后，会看到目录下多了两个xml文件，我还创建了static文件夹用来存放静态资源css、js、images（图片等），和views文件夹用来存放映射文件（例如JSP）  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDQxMTU2OQ_size_16_color_FFFFFF_t_70 9]  
其中java文件是用来建包的，现在可以对SpringMVC进行设置了，首先配置web.xml 。他自己自动生成的可能不是这种，直接用下面的替换就可以了

<?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>

配置dispatcher-servlet.xml，负责mvc的配置

<?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:mvc="http://www.springframework.org/schema/mvc"
          xmlns:context="http://www.springframework.org/schema/context"
          xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    
       
    
       
       <context:annotation-config/>
    
       
       <mvc:annotation-driven/>
    
       
       
       <mvc:resources mapping="/css/**" location="/static/css/"/>
       <mvc:resources mapping="/js/**" location="/static/js/"/>
       <mvc:resources mapping="/image/**" location="/static/images/"/>
       <mvc:default-servlet-handler />  
    
       
       
       <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.gx.controller"/>
    
    </beans>

配置applicationContext.xml，负责一些非MVC组件的配置，暂时没有所以是空的，但也可以扫描一下

以上就是配置好了 可以创建文件使用了哦！亲测可用
