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][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。
