Jersey+mybatis实现web项目第一篇

---恢复内容开始---

Jesery第一篇：实现Jesery前后台页面交互，Form表单提交，后台控制页面跳转

该项目中有实现的功能：

1. Mybatis实现后台数据持久化
2. Jersey页面数据提交
3. 后台页面跳转
4. 工厂设计模式根据beans.xml,获得对象
5. JerseyClient测试

jar文件如下：

几个配置文件代码：

1.mybatis-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://www.mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <!-- properties配置 -->
    <!-- 这些属性都是可外部配置且可动态替换的，
    既可以在典型的 Java 属性文件中配置，
    亦可通过 properties 元素的子元素来传递。 -->
    <properties resource="db.properties">
    <!-- 可在此属性中动态替换properties中的对应属性 -->
    <!--
        <property name="" value=""/>
    -->
    </properties>
    <!-- <settings>

          <typeAlias type="cn.nuist.chenlong.pojo.User" alias="User"/>
      </typeAliases>
    <!-- setting属性会修改Mybatis在运行时的行为方式 -->
    <!-- typeAliases别名是为Java类型命名一个短的名字 -->
