SpringMVC IOC容器和Spring IOC容器关系

SpringMVC IOC容器和Spring IOC容器作为父子关系容器，SpringMVC容器内的Bean可以访问父容器的Bean，反之Spring 中的Bean不能访问SpringMVC 子容器的Bean。

1.Spring 通常管理除去@Controller 之外的Bean,SpringMVC 管理@Controller 的Bean,SpringMVC内的Bean可以使用@Autowire,@Resource注入Spring容器管理的Bean，反之不行。

2.要是为了快速方便开发，完全可以用SpringMVC框架

web.xml 配置SpringMVC servlet

  <!-- 配置spring 容器 -->
  <context-param>
  	<param-name>contextConfigLocation</param-name>
  	<param-value>classpath:application.xml</param-value>
  </context-param>
  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <!-- springMVC 前端控制器 -->
  <servlet>
  	<servlet-name>spring-mvc</servlet-name>
  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  	<init-param>
  		<param-name>contextConfigLocation</param-name>
  		<param-value>classpath:spring-mvc.xml</param-value>
  	</init-param>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
  	<servlet-name>spring-mvc</servlet-name>
  	<url-pattern>/</url-pattern>
  </servlet-mapping>
  
  <!-- 编码过滤器 解决post 乱码-->
  <filter>
  	<filter-name>encoding</filter-name>
  	<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
  	<init-param>
  		<param-name>encoding</param-name>
  		<param-value>utf-8</param-value>
  	</init-param>
  </filter>
  <filter-mapping>
  	<filter-name>encoding</filter-name>
  	<url-pattern>/*</url-pattern>
  </filter-mapping>

配置Log4j日志

log4j.rootLogger = DEBUG,stdout
 
#console
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n
 
#file
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender

log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG

log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} - [ %p ]  %l%n%m%n

ssm 项目配置文件相对使用频繁，为提高开发效率做一个简单的记录方便复制粘贴。
