(5)流程定义列表:activiti自定义流程之Spring整合activiti-modeler5.16实例(五):流程定义列表
1.启动流程并分配任务是单个流程的正式开始,因此要使用到runtimeService接口,以及相关的启动流程的方法。我习惯于用流程定义的key启动,因为有多个版本的流程定义时,用key启动默认会使用最新版本。同时,因为启动中查询了流程部署时xml文件中流程节点的信息,也用到了repositoryService及相关方法。
package model; public class applyModel { /** * 流程定义id */ private String proDefId; /** * 流程定义的key */ private String key; private String name; /** * 申请人 */ private String appPerson; /** * 原因 */ private String cause; /** * 内容 */ private String content; /** * 处理人,即下一个任务节点的受理人 */ private String proPerson; public String getKey() { return key; } public void setKey(String key) { this.key = key; } public String getAppPerson() { return appPerson; } public void setAppPerson(String appPerson) { this.appPerson = appPerson; } public String getCause() { return cause; } public void setCause(String cause) { this.cause = cause; } public String getContent() { return content; } public void setContent(String content) { this.content = content; } public String getProPerson() { return proPerson; } public void setProPerson(String proPerson) { this.proPerson = proPerson; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getProDefId() { return proDefId; } public void setProDefId(String proDefId) { this.proDefId = proDefId; } @Override public String toString() { return "applyModel [proDefId=" + proDefId + ", key=" + key + ", name=" + name + ", appPerson=" + appPerson + ", cause=" + cause + ", content=" + content + ", proPerson=" + proPerson + "]"; } }
