activiti自定义流程之Spring整合activiti-modeler5.16实例（一）：环境搭建
项目中需要整合activiti-modeler自定义流程，找了很多资料后，终于成功的跳转到activiti-modeler流程设计界面，以下是记录：
一、整合基础：eclipse4.4.1、tomcat7、jdk1.7、mysql5.6.25、maven3.2.5、activiti5.16.3、spring4.0.9
二、步骤：
1、下载activiti-5.16.3.zip: http://www.activiti.org/download.html
2、解压zip文件，解压后的目录打开如下：
3、打开上图中wars，可看到如下：
4、把上图中的api、editor、explorer、libs复制到项目的webapp下，如图：
5、进入第三步所示的WEB-INF的classes目录，可看到如图：
6、把上图中的editor.html、stencilset.json、plugins.xml复制到项目的src/main/sources中，（spring.xml是自己建立的）如图：
7、配置web.xml文件，整个文件内容如下：

org.springframework.web.filter.CharacterEncodingFilter
字符集编码
encoding
UTF-8
encodingFilter
/*

org.restlet.ext.servlet.ServerServlet
org.restlet.application

contextConfigLocation
classpath:spring.xml
springMVC
*.do
activiti.html
activiti.htm
activiti.jsp
default.html
default.htm
default.jsp
8、使用maven导入需要的pring、activiti以及mysql的jar包。Pom.xml内容如下：

9、建立spring的配置文件spring.xml,如下：
text/html;charset=UTF-8
10、建立controller类，用来控制页面跳转到activiti-modeler流程设计页面：
package controllers;
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.activiti.editor.constants.ModelDataJsonConstants;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.repository.Model;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;
@Controller
public class ActivitiController {
@Autowired
private RepositoryService repositoryService;
/**
* 查询生日列表
*
* @param req
* @return
*/
@RequestMapping(value = "/activiti.do", method = RequestMethod.GET, produces = "application/json;charset=utf-8")
@ResponseBody
public Object brithdayList(HttpServletRequest req) {
Map map = new HashMap();
map.put("name", "activiti");
return map;
}
@RequestMapping(value = "/create.do", method = RequestMethod.GET, produces = "application/json;charset=utf-8")
public void create(
@RequestParam("name") String name,
@RequestParam("key") String key,
@RequestParam(value = "description", required = false) String description,
HttpServletRequest request, HttpServletResponse response) {
try {
ObjectMapper objectMapper = new ObjectMapper();
ObjectNode modelObjectNode = objectMapper.createObjectNode();
modelObjectNode.put(ModelDataJsonConstants.MODEL_NAME, name);
modelObjectNode.put(ModelDataJsonConstants.MODEL_REVISION, 1);
modelObjectNode.put(ModelDataJsonConstants.MODEL_DESCRIPTION,
org.apache.commons.lang3.StringUtils
.defaultString(description));
Model newModel = repositoryService.newModel();
newModel.setMetaInfo(modelObjectNode.toString());
newModel.setName(name);
newModel.setKey(key);
repositoryService.saveModel(newModel);
ObjectNode editorNode = objectMapper.createObjectNode();
editorNode.put("id", "canvas");
editorNode.put("resourceId", "canvas");
ObjectNode stencilSetNode = objectMapper.createObjectNode();
stencilSetNode.put("namespace",
"http://b3mn.org/stencilset/bpmn2.0#");
editorNode.put("stencilset", stencilSetNode);
repositoryService.addModelEditorSource(newModel.getId(), editorNode
.toString().getBytes("utf-8"));
response.sendRedirect(request.getContextPath()
+ "/service/editor?id=" + newModel.getId());
} catch (Exception e) {
e.getStackTrace();
}
}
} 11、修改index.jsp为activiti.html:
Hello World!
activiti
12、启动项目，使用http://localhost:8080/activitiTest1访问项目，看到如下页面：
13、点击提交后，跳转到流程图设计界面：
