springmvc 初步

1,新建maven工程

maven update

如没有 在下新建 java目录和test/java 目录  然后maven update

如果 index.jsp 出现 javax.servlet.http.HttpServlet 错误

2,打开pom.xml 输入spring mvc 和jedis需要的jar包

(1) 修改之前可以更换下载的镜像地址，以增加下载速度，此处用的是阿里的镜像

打开F:\apache-maven-3.3.9\conf\settings.xml; 

   
      alimaven
      aliyun maven
  　　http://maven.aliyun.com/nexus/content/groups/public/
      central        
   

(2)pom.xml 添加

里面有些许的冗余暂就不做删除了。

(2),修改web.xml

    web项目
    
   	
        contextConfigLocation
        classpath:/spring/spring-context.xml
    
    
        org.springframework.web.context.ContextLoaderListener
    
    
		org.springframework.web.context.request.RequestContextListener
	
    
    
    
    
    
        spring mvc servlet
        DispatcherServlet
        org.springframework.web.servlet.DispatcherServlet
        
            spring mvc 配置文件
            contextConfigLocation
            classpath:spring/spring-mvc.xml
        
        1
    

    
        DispatcherServlet
        *.do
    
    
    
    
    
    
        encodingFilter
        
            org.springframework.web.filter.CharacterEncodingFilter
        
        
            encoding
            UTF-8
        
        
            forceEncoding
            true
        
    
    
        encodingFilter
        *
    
	 
    
		404
		/error/404.html
	
	
		index.jsp
	

(3) 新建spring-mvc

(4),新建spring-context

(5) 新建controller
