参照实验室这边案例做一个简单的maven webapp项目

流程 ：

首先写出一个简单的前端页面。

之后写配置文件、dao、domain等等，注意这里可以使用generator进行自动配置

实验室这边配置文件如下：

其实主要的配置文件就分为6“个”。

applicationContext.xml与app-biz.xml、app-data.xml、esconnect.properties是一个。

generatorConfig是一个。

log4j.properties是一个。

sqlMapConfig是一个。

web.xml是一个。

com.cfWeb.mapping下面的全部xml文件都可以算一个。

先做好前端，现在它的配置文件都是空的。

出现页面后，修改pom文件，maven install

之后首先修改web.xml文件，将其改为

    <!-- 编码 -->

        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
</web-app>

之后修改applicationContext.xml文件，将其改为

<?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:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="

    <context:component-scan base-package="com.LoginTest" />
</beans>

顺便将log4j.properties修改为

log4j.rootLogger=INFO,infoLog,errorLog,console

log4j.appender.errorLog = org.apache.log4j.DailyRollingFileAppender
log4j.appender.errorLog.File = ../appLogs/cfWeb_error.log
log4j.appender.errorLog.Append = true
log4j.appender.errorLog.Threshold = ERROR
log4j.appender.errorLog.DatePattern='.'yyyy-MM-dd
log4j.appender.errorLog.layout=org.apache.log4j.PatternLayout
log4j.appender.errorLog.layout.ConversionPattern=[%d{yyyy-MM-dd HH:mm:ss}] %c{1}.%t - %-5p -  method:%l%n%m%n

log4j.appender.infoLog=org.apache.log4j.DailyRollingFileAppender
log4j.appender.infoLog.File= ../appLogs/cfWeb_info.log
log4j.appender.infoLog.Threshold = INFO
log4j.appender.infoLog.DatePattern='.'yyyy-MM-dd
log4j.appender.infoLog.layout=org.apache.log4j.PatternLayout
log4j.appender.infoLog.layout.ConversionPattern=[%d{yyyy-MM-dd HH:mm:ss}] %c{1}.%t - %-5p -  method:%l%n%m%n

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%5p [%t] (%F:%L) %d{HH:mm:ss,SSS} -- %m%n

剩下的配置文件都是为空。

在这个过程中会遇到很多常见问题，看看properties 的deployment Assembly是否添加了maven包，java buildpath是否添加了maven包，等等。

于是run on server会出现下面这样的结果

之后就存在两个需要解决的问题（顺序需要考虑）：

1、如何使用mybatis自动加入数据

2、前端与后台如何进行交互
