这一节主要是利用SpringMVC、Spring、Mybatis和Velocity，首先将其整合在一起，搭建Web开发的环境，以下会列出核心代码。
pom.xml
由于本工程是Maven管理，所以方便大家使用，将pom.xml的内容完整展现出来，如下：

<property name="toolboxConfigLocation" value="WEB-INF/conf/tools.xml" />
</bean>
</beans>
spring-beans.xml
该配置中主要配置数据库、事务及Mybatis映射相关，如下：

<property name="dataSource" ref="dataSource" />
</bean>
<!-- 注解式事务管理，需要在Service类上标注@Transactional -->
<tx:annotation-driven transaction-manager="transactionManager" />
</beans>
web.xml
配置Web容器相关，如下：

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Toolbox20View
为了使用原生的Spring派发的同时，有支持Velocity Tools 2.0，必须引入的对象，如下：
package com.tongtongxue.yp.common.web;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.velocity.context.Context;
import org.apache.velocity.tools.Scope;
import org.apache.velocity.tools.ToolManager;
import org.apache.velocity.tools.ToolboxFactory;
import org.apache.velocity.tools.view.ViewToolContext;
import org.springframework.web.servlet.view.velocity.VelocityToolboxView;
/**
* 实现了Velocity Tools 2.0的装载
* @author 芝加哥
* @since [2017-01-08]
*/
public class Toolbox20View extends VelocityToolboxView {
private static ToolboxFactory toolboxFactory = null;
@Override
protected Context createVelocityContext(Map model, HttpServletRequest request, HttpServletResponse response) throws Exception {
ViewToolContext vtc;
vtc = new ViewToolContext(getVelocityEngine(), request, response, getServletContext());
vtc.putAll(model);
if (toolboxFactory == null) {
ToolManager toolManager = new ToolManager();
toolManager.setVelocityEngine(getVelocityEngine());
toolManager.configure(getServletContext().getRealPath(getToolboxConfigLocation()));
toolboxFactory = toolManager.getToolboxFactory();
}
if (this.getToolboxConfigLocation() != null) {
if (toolboxFactory.hasTools(Scope.REQUEST)) {
vtc.addToolbox(toolboxFactory.createToolbox(Scope.REQUEST));
}
if (toolboxFactory.hasTools(Scope.APPLICATION)) {
vtc.addToolbox(toolboxFactory.createToolbox(Scope.APPLICATION));
}
if (toolboxFactory.hasTools(Scope.SESSION)) {
vtc.addToolbox(toolboxFactory.createToolbox(Scope.SESSION));
}
}
return vtc;
}
}
AuthController
用户登录信息的控制器类，如下：
package com.tongtongxue.yp.auth.controller;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
/**
* 用户登录信息的控制器类
* @author 芝加哥
* @since [2017-01-08]
*
*/
@Controller
@RequestMapping("/auth")
public class AuthController {
private Logger logger = Logger.getLogger(getClass());
/**
* 加载出用户注册页面
* @return
*/
@RequestMapping(value = "signup", method = RequestMethod.GET)
public String signup() {
return "auth/signup";
}
}
效果
此节主要目的是为了配置Web开发的环境，所以启动tomcat后，输入如下链接：
http://localhost:8080/yp/auth/signup
效果如下：
以后章节会继续往下开发，希望大家不断关注，谢谢。。。
