无配置文件 搭建
今天搞了个spring3.1+servlet3 无配置项目，事到此时终于算出了一个小东东了
记录于此，已被后用。
1.创建项目，使用eclipse+tomcat7
2.导入spring的包，除此之外还导入了asm-2.2.2.jar、cglib-nodep-2.1_3.jar（这个别导入hibernate的了）、jstl-1.0.2.jar、jackson-all-1.9.1.jar、commons-logging-1.1.1.jar、mysql-connector-java-5.1.12-bin.jar
3.删除了web.xml，准备二个文件：
? ?jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/db_smg?useUnicode=true&charaterEncoding=UTF-8jdbc.username=rootjdbc.password=****
??properties-config.xml
? ??<?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"xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd"> <context:property-placeholder location="classpath:/com/acme/jdbc.properties"/> <mvc:resources mapping="/static/**" location="/static/"/> </beans>
?4.编写启动容器加载的java文件和java 程序代替的配置
Initializer.java

6. 编写测试程序，启动项目测试（附件含有）
