Hibernate3.3.2+Spring2.5.5+Struts2.1.6+Extjs3.0.0 Annotations方式快速开发框架2.doc

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。 package?com.xy.action;import?java.util.HashSet;import?java.util.List;import?java.
