2.容器xml的配置
spring.xml配置，即上下文context容器bean的配置

    
     
    
     
        
        
        
        
    
     
        
         
         
         
        
            
                
                    
                        reasonable=true
                    
                
            
        
      
    
        
        
     
    
    
        
    

springMVC的容器配置

web.inf的配置，设置好容器参数

    
        /pages/login.html
     

     
        contextConfigLocation
        classpath*:spring.xml
    


    
        org.springframework.web.context.ContextLoaderListener
     
    
        dispatcherServlet
        org.springframework.web.servlet.DispatcherServlet
         
        
            contextConfigLocation
            classpath*:springmvc.xml
         
        1
     
    
        dispatcherServlet
        *.do
     

    
        httpMethodFilter
        org.springframework.web.filter.HiddenHttpMethodFilter
    
    
        httpMethodFilter
        /*
     

    
        characterEncodingFilter
        org.springframework.web.filter.CharacterEncodingFilter 
        





            encoding
            UTF-8
         
        
            forceRequestEncoding
            true
         
        
            forceResponseEncoding
            true
        
    
    
        characterEncodingFilter
        /*
    

3.mabatis的反向生成
配置mybatis的xml配置

配置log4j

log4j.rootLogger=DEBUG,stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

配置数据库

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/myssm_kkb? useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=GMT
jdbc.username=root
jdbc.password=xxxx

配置mybatisgenerater.xml

生成pojo,mapper

4.在上下文spring.xml容器配置中加注service扫描路径，service加注@Service注解，controller层加注@Controller，自编写配置类加注@Component。前端返回json格式，controller还需加注@ResponseBody,@RequestMapping映射地址等。

5.设置事务
