开始第一个SpringMVC

Android Studio和Idea师出同门
Idea可以说是Java Web开发利器

下面是笔者的第一个maven项目，很简单，只是记录一下过程，轻拍
打开idea新建一个maven项目

填写包名和项目名

点击Next完成项目创建
如果出现mvn archetype:generate速度非常缓慢
建议如下设置改为本地获取

VM Options: -DarchetypeCatalog=internal

配置依赖
Android中Gradle配置依赖很简单，同样的maven的也类似
可以去
http://mvnrepository.com/
寻找相关的依赖
在pom.xml中配置相关的依赖，目前笔者一切从简，只配置了Spring的相关依赖，后续包括Mybatis等等的并未配置

新建java文件夹，右键

Mark Directory As -> Sources Root

在java文件夹下新建包名cn.main.web.controller
在resources目录下新建配置文件
mvc-dispatcher-servlet.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"

    <!--配置控制器-->
    <context:component-scan base-package="cn.main.web.controller"></context:component-scan>

    <!--配置注解驱动-->
    <mvc:annotation-driven></mvc:annotation-driven>

    <mvc:annotation-driven >
        <!-- 消息转换器 -->
        <mvc:message-converters register-defaults="true">
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <property name="supportedMediaTypes" value="text/html;charset=UTF-8"/>
            </bean>
        </mvc:message-converters>

    @RequestMapping("/welcome.do")
    @ResponseBody
    public String welcome(){
        return "Welcome...";
    }

}
