Hibernate3.3.2+Spring2.5.5+Struts2.1.6+Extjs3.0.0 Annotations方式快速开发框架(下)

Hibernate3.3.2+Spring2.5.5+Struts2.1.6+Extjs3.0.0 Annotations方式快速开发框架(下)

五、整合Struts2、Extjs

将struts-2.1.6\lib目录下的struts2-codebehind-plugin-2.1.6.jar、struts2-core-2.1.6.jar、struts2-spring-plugin-2.1.6.jar、xwork-2.1.2.jar、ognl-2.6.11.jar、freemarker-2.3.13.jar、commons-fileupload-1.2.1.jar、commons-io-1.3.2.jar复制到项目WebContent\lib下。

另外还需jsonplugin-0.34.jar包，使struts2 action返回json类型。

新建一个entity接口，action层需使用该接口调用实体主键。

package  com.xy.entity;

public   interface  BaseEntity {
     public   long  getId();
}

修改Demo实体，使其实现BaseEntity接口

package  com.xy.entity.demo;

import  javax.persistence.Column;
import  javax.persistence.Entity;
import  javax.persistence.GeneratedValue;
import  javax.persistence.GenerationType;
import  javax.persistence.Id;
import  javax.persistence.SequenceGenerator;
import  javax.persistence.Table;
import  javax.persistence.TableGenerator;

import  com.xy.entity.BaseEntity;

@Entity
@Table(name = " HSSEA_DEMO " )
public   class  Demo  implements  BaseEntity {
    @Id
    @GeneratedValue(strategy = GenerationType.TABLE, generator = " hssea_demo " )
    @TableGenerator(name  =   " hssea_demo " ,
                    table = " OBJECT_ID " ,
                    pkColumnName = " NAME " ,
                    valueColumnName = " VALUE " ,
                    pkColumnValue = " HSSEA_DEMO_PK " ,
                    initialValue = 1 ,
                    allocationSize = 1
    )
    @SequenceGenerator(name = " hssea_demo_seq " , sequenceName = " seq_hssea_demo " , allocationSize = 1 )
     private   long  id;
    @Column(name = " CODE " )
     private  String code;
    @Column(name = " DESCRIPTION " )
     private  String description;
     public   long  getId() {
         return  id;
    }
     public   void  setId( long  id) {
         this .id  =  id;
    }
     public  String getCode() {
         return  code;
    }
     public   void  setCode(String code) {
         this .code  =  code;
    }
     public  String getDescription() {
         return  description;
    }
     public   void  setDescription(String description) {
         this .description  =  description;
    }
}

增加struts2与extjs交互抽象类，完成分页、排序、增删改查。

在WebContent下新增extjs和demo目录，将ext-3.0.0目录下的ext-all.js和resources整个目录、ext-3.0.0\adapter\ext目录下ext-base.js复制到新建的extjs目录下。
在demo目录下新建list.jsp

到此完成所有演示代码，右击项目，Run As -> Run on Server，用之前设置的tomcat启动，服务启动后，浏览器http://localhost:8080/HSSEADemo/demo/list.jsp，进行增删改查操作。


最终项目结构如下：
