Spring4.x、SpringMVC和DButils整合

tomcat 8、Spring 4.X、JDK1.8

需要jar包：

1）日志组件：log4j

 # debug < info < warn < error
 log4j.rootLogger=warn, console, file

 ###################console####################
 log4j.appender.console=org.apache.log4j.ConsoleAppender
 log4j.appender.console.layout=org.apache.log4j.PatternLayout
 log4j.appender.console.layout.ConversionPattern=%d{yyy-MMM-dd HH:mm:ss} %p %m %L %n

 ###################file######################
 log4j.appender.file=org.apache.log4j.RollingFileAppender
 log4j.appender.file.File=../logs/SpuerPPP.log
 log4j.appender.file.MaxFileSize=5kb
 log4j.appender.file.MaxBackupIndex=100
 log4j.appender.file.layout=org.apache.log4j.PatternLayout
 log4j.appender.file.layout.ConversionPattern=%d %c.%M()-%m%n

2）web.xml：注册spring组件为项目启动时加载

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
   <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>classpath:spring.xml</param-value>
     </init-param>
     <load-on-startup>1</load-on-startup>
   </servlet>
   <servlet-mapping>
     <servlet-name>springMVC</servlet-name>
     <url-pattern>*.do</url-pattern>
   </servlet-mapping>
   <filter>
     <filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
     <url-pattern>/*</url-pattern>
   </filter-mapping>
 </web-app>

3）spring.xml：整合
