activiti（一）spring4+hibernate4

最近有个项目就是对activity进行封装，用于企业流程驱动。
第一步就是搭建环境咯，首先我们先将hibernate4+spring4搭建好，再将activity包放入到项目中。
下载spring包和hibernate包，这里就不讲解了，大概需要的jar包如下：

persistence-mysql.properties的内容：

# jdbc.X
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/go_bi?createDatabaseIfNotExist=true
jdbc.user=root
jdbc.pass=root

# hibernate.X
hibernate.connection.driverClass=org.gjt.mm.mysql.Driver
hibernate.connection.url=jdbc:mysql://127.0.0.1:3306/go_bi
hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
hibernate.connection.username=root
hibernate.connection.password=root
hibernate.show_sql=true
hibernate.hbm2ddl.auto=update

为了测试环境是否正确，编写了个实体类：

package cn.com.going.activity.domain;

import javax.persistence.*;

/**
 * Created by btshj on 2015/11/27.
 */
@Entity
@Table(name="G_USER")
public class User {
    public User(){
        super();
    }

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="id")
    private Integer id;

    @Column(name="user_name",length=32)
    private String user_name;

    @Column(name="age")
    private Integer age;

    @Column(name="nice_name",length=32)
    private String nice_name;

    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getUser_name() {
        return user_name;
    }
    public void setUser_name(String user_name) {
        this.user_name = user_name;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
    public String getNice_name() {
        return nice_name;
    }
    public void setNice_name(String nice_name) {
        this.nice_name = nice_name;
    }
}

编写了个controller类

package cn.com.going.activity.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Created by wei on 2016/1/22.
 */
@Controller
public class RestConstroller {

    @RequestMapping(value = "/login/{user}", method = RequestMethod.GET)
    public ModelAndView myMethod(HttpServletRequest request, HttpServletResponse response,
                                 @PathVariable("user") String user, ModelMap modelMap) throws Exception {
        modelMap.put("loginUser", user);
        return new ModelAndView("/login/hello", modelMap);
    }


    @RequestMapping(value = "/welcome", method = RequestMethod.GET)
    public String registPost(Model model) {
        return "/index";
    }
}

将项目在tomcat中跑起来，然后在浏览器中输入：
http://127.0.0.1:8080/go-activity/welcome

表示springMVC配置成功。

打开mysql 看下数据库表是否生成，如果表生成成功，则表示hibernate也配置成功。

下节将介绍怎么将activity添加到项目中。
