jbpm入门

  先生成jbpm数据库表,如何生成数据库表呢

  在官网下载jbpm-4.4.zip文件,然后在cmd窗口下进入install目录,

  执行 ant -Ddatabase=mysql create.jbpm.schema 就可以生成jbpm的表了

  然后在项目下创建一个jbpm.cfg.xml的文件

  

<?xml version="1.0" encoding="UTF-8"?>

<jbpm-configuration>

  <import resource="jbpm.default.cfg.xml" />
  <import resource="jbpm.tx.hibernate.cfg.xml" />
  <import resource="jbpm.jpdl.cfg.xml" />
  <import resource="jbpm.bpmn.cfg.xml" />
  <import resource="jbpm.identity.cfg.xml" />
  <import resource="jbpm.businesscalendar.cfg.xml" />
  <import resource="jbpm.console.cfg.xml" />
  <!--  
  <import resource="jbpm.jobexecutor.cfg.xml" />
-->
</jbpm-configuration>

创建一个jbpm.hibernate.cfg.xml

<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE hibernate-configuration PUBLIC
  "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
  "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
  <session-factory>
    <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
    <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/jbpmdb</property>
    <property name="hibernate.connection.username">root</property>
    <property name="hibernate.connection.password">root</property>
    <property name="hibernate.show_sql">false</property>
    <property name="hibernate.format_sql">false</property>

    <mapping resource="jbpm.repository.hbm.xml" />
    <mapping resource="jbpm.execution.hbm.xml" />
    <mapping resource="jbpm.history.hbm.xml" />
    <mapping resource="jbpm.task.hbm.xml" />
    <mapping resource="jbpm.identity.hbm.xml" />
  </session-factory>
</hibernate-configuration>

　　如何通过eclipse创建一个jbpm 4 process definition文件,然后大压缩zip使用html上传到服务器

<s:actionmessage/>
  <s:form action="upload" method="post" enctype="multipart/form-data">
      <s:file name="file" ></s:file>
      <s:submit value="上传"></s:submit>
  
  </s:form>

package com.chen;

import java.io.File;
import java.io.FileInputStream;
import java.util.zip.ZipInputStream;

import org.jbpm.api.Configuration;
import org.jbpm.api.ProcessEngine;
import org.jbpm.api.RepositoryService;

import com.opensymphony.xwork2.ActionSupport;

public class UploadAction extends ActionSupport{

    private File file;
    public File getFile() {
        return file;
    }
    public void setFile(File file) {
        this.file = file;
    }
    @Override
    public String execute() throws Exception {
        ProcessEngine p = Configuration.getProcessEngine();
        
        RepositoryService r = p.getRepositoryService();
        String id = r.createDeployment().addResourcesFromZipInputStream(
                new ZipInputStream(new FileInputStream(file))).deploy();
        this.addActionMessage("部署id为" + id);
        return "success";
    }
    
}

这让就完成了jbpm流程的基本部署,下一节我们讲一下jbpm流程的使用.
