最近自己独立弄一个activiti项目，写一下整合过程：
环境：jdk1.7 tomcat7.0 maven3.5 eclipse mysql5.5
--我的工程结构，怎么创建一个maven项目就不在这里写了：
--首先见表
CREATE TABLE `t_user` (
`USER_ID` int(11) NOT NULL auto_increment,
`USER_NAME` char(30) NOT NULL,
`USER_PASSWORD` char(10) NOT NULL,
`USER_EMAIL` char(30) NOT NULL,
PRIMARY KEY (`USER_ID`),
KEY `IDX_NAME` (`USER_NAME`)
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8;
--随便插入几条数据
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (1, 'aa', '1234567', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (2, 'cc', '1234567', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (3, 'dd', '1234567', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (4, 'ee', '1234567', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (5, 'artaahur', '1234567', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (6, 'vvvv', '1234567', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (7, 'ffff', '1234567', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (8, 'aaaa', '1234567', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (9, 'aaaaa', '1234567', '[email protected]');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD, USER_EMAIL) VALUES (10, 'vvvvvv', '1234567', '[email protected]');
---上面数据库的操作到这里就够了。

-------右键运行测试方法，完成测试。没有配置activiti的数据库，在运行完后会自动创建表。
到这里配置好spring+activiti+mybatis+mysql!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
=====================================================
这里开始添加spirngMVC，并转换maven工程为web项目
接上面的工程接着说，此时要加spingMVC之前，工程得再稍微转换下
此时webapp下的结果还没有显示出来，因为此时我们还没有配置此的项目为web项目
再次进去Properties配置，如下图所示：如果没有显示如下，那就先把dynamic web module的√给去掉，然后重新再打开 这个
进入，然后输入如下内容
确定OK之后,webapp下面就会自动生成一些文件，如下
--------配置SpringMVC
--pom文件需要新增两个配置，上面我已经做了解释，在贴一下
<!-- spring MVC 在转换为web项目后添加的begin -->
<!-- javaee-api包 注意和项目使用的JDK版本对应 -->
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
<!-- javaee-web-api包 注意和项目使用的JDK版本对应 -->
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
----- 在src/main/resource中添加springmvc文件夹，然后添加文件spring-mvc.xml，内容如下：
<?xml version="1.0" encoding="UTF-8"?>

<!-- 对模型视图添加前后缀 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/view/" p:suffix=".jsp"/>
</beans>
-----配置web,xml
----web.xml
<?xml version="1.0" encoding="UTF-8"?>

------
添加index.jsp
在src/main/webapp/WEB-INF下新建一个文件夹view,添加一个index.jsp，内容如下：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<html>
<body>
<h2>Hello World!</h2>
${user.userId}
<br> ${user.userName}
<br> ${user.userPassword}
<br> ${user.userEmail}
<br>
</body>
</html>
-----最后就是controller的书写了
package com.travesky.bluesky.activiti.controller;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.bind.annotation.RequestMapping;
import com.travesky.bluesky.activiti.domain.User;
import com.travesky.bluesky.activiti.service.UserService;
/**
*
* @author Ancan
*
*/
@Controller
public class UserController {
@Resource
private UserService userService;
@RequestMapping("/")
public ModelAndView getIndex() {
ModelAndView mav = new ModelAndView("index");
User user = userService.selectUserById(1);
mav.addObject("user", user);
return mav;
}
}
-----到这里，已经全部整合完毕，但是，由于是maven项目，在转换成web项目后，我们要添加jar的依赖到项目
--右键项目，properties---》deployment Assembly-->点击add，添加jar包如下图
-----添加完依赖后，就可以通过tomcat运行项目了
接下来控制台就会打印日志出来了！如下
打印浏览器，输入网址：http://localhost:8088/activiti/
