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:
