springMvc+mybatis+spring 整合 包涵整合activiti 基於maven
阿新 • • 發佈：2018-12-14
最近自己獨立弄一個activiti專案，寫一下整合過程：
環境：jdk1.7 tomcat7.0 maven3.5 eclipse mysql5.5
--我的工程結構，怎麼建立一個maven專案就不在這裡寫了：
--首先見表
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;
--隨便插入幾條資料
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', ' ---上面資料庫的操作到這裡就夠了。

}
protected FlowElement createServiceTask(String name) {
ServiceTask stask = new ServiceTask();
stask.setId("sid");
stask.setName(name);
stask.setImplementation("activitiTest.PrintVariables");
String implementationType = ImplementationType.IMPLEMENTATION_TYPE_DELEGATEEXPRESSION;
stask.setImplementationType(implementationType);
return stask;
}
}
-------右鍵執行測試方法，完成測試。沒有配置activiti的資料庫，在執行完後會自動建立表。
到這裡配置好spring+activiti+mybatis+mysql!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
=====================================================
這裡開始新增spirngMVC，並轉換maven工程為web專案
接上面的工程接著說，此時要加spingMVC之前，工程得再稍微轉換下
此時webapp下的結果還沒有顯示出來，因為此時我們還沒有配置此的專案為web專案
再次進去Properties配置，如下圖所示：如果沒有顯示如下，那就先把dynamic web module的√給去掉，然後重新再開啟 這個
進入，然後輸入如下內容
確定OK之後,webapp下面就會自動生成一些檔案，如下
--------配置SpringMVC
--pom檔案需要新增兩個配置，上面我已經做了解釋，在貼一下
<!-- spring MVC 在轉換為web專案後新增的begin -->
<!-- javaee-api包 注意和專案使用的JDK版本對應 -->
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
<!-- javaee-web-api包 注意和專案使用的JDK版本對應 -->
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>7.0</version>
<scope>provided</scope>
</dependency>
----- 在src/main/resource中新增springmvc資料夾，然後新增檔案spring-mvc.xml，內容如下：

------
新增index.jsp
在src/main/webapp/WEB-INF下新建一個資料夾view,新增一個index.jsp，內容如下：
<%@ 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>
-----最後就是controller的書寫了
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;
}
}
-----到這裡，已經全部整合完畢，但是，由於是maven專案，在轉換成web專案後，我們要新增jar的依賴到專案
--右鍵專案，properties---》deployment Assembly-->點選add，新增jar包如下圖
-----新增完依賴後，就可以通過tomcat執行專案了
接下來控制檯就會列印日誌出來了！如下
列印瀏覽器，輸入網址：http://localhost:8088/activiti/
