JSF+Spring+JPAHibernate实现的环境搭建Word文件下载.docx

4、er/variable-resolver再加入facelets框架的标签支持包，整个环境包大致如下图所示：4. 上面的配置好了，JSF和Spring就集成起来了。下面我们加入JPA支持，并且将JPA和Spring集成起来。首先加入persistence.xml文件，内容如下：?xml version=1.0 encoding=UTF-8persistence xmlns= xmlns:xsi=http:/www.w3.org/2001/XMLSchema-instance xsi:schemaLocation= version=persistence-unit name=JSJDemoPU t

5、ransaction-type=RESOURCE_LOCALproviderorg.hibernate.ejb.HibernatePersistenceclasstest.vo.Testproperties - Hibernate 方言（只有Hibernate 才需要设置） -property name=hibernate.dialect value=org.hibernate.dialect.MySQLDialect /- Hibernate 显示调试 SQL -hibernate.show_sql value=true - Hibernate 格式化sql -hibernate.forma

6、t_sqlhibernate.hbm2ddl.autoupdate/properties/persistence-unit/persistence之后建立一个值对象，代码如下：package mangerTeam.vo;import java.io.Serializable;import java.util.Set;import javax.persistence.Basic;import javax.persistence.CascadeType;import javax.persistence.Column;import javax.persistence.Entity;import ja

7、vax.persistence.FetchType;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;import javax.persistence.JoinColumn;import javax.persistence.JoinTable;import javax.persistence.Lob;import javax.persistence.ManyToMany;import javax.persistence.ManyT

8、oOne;import javax.persistence.Table;/* * 运动员实体 * * author 刘岩 */EntityTable（name = player）public class PlayersVO implements Serializable Id GeneratedValue（strategy = GenerationType.AUTO） Column（name = id, unique = true, nullable = false） private Integer id;name private String name; ManyToOne（optional

9、=true, fetch = FetchType.LAZY） JoinColumn（name = teamId private TeamVO teamVO; ManyToOne（fetch = FetchType.LAZY） JoinColumn（nullable=false,name = nationalityId private NationalityVO nationalityVO; Lob Basic（fetch = FetchType.LAZY）pic private byte pic;mess private String mess; ManyToMany（cascade = Ca

10、scadeType.REFRESH, fetch = FetchType.LAZY） JoinTable（name = plays_position, joinColumns = JoinColumn（name = playerId） , inverseJoinColumns = JoinColumn（name = positionId） ） private Set positions; public Integer getId（） return id; public void setId（Integer id） this.id = id; public String getName（） re

11、turn name; public void setName（String name） this.name = name; public Set getPositions（） return positions; public void setPositions（Set positions） this.positions = positions; public TeamVO getTeamVO（） return teamVO; public void setTeamVO（TeamVO teamVO） this.teamVO = teamVO; public NationalityVO getNa

12、tionalityVO（） return nationalityVO; public void setNationalityVO（NationalityVO nationalityVO） this.nationalityVO = nationalityVO; public byte getPic（） return pic; public void setPic（byte pic） this.pic = pic; public String getMess（） return mess; public void setMess（String mess） this.mess = mess;之后写DA

13、O，无论你是用IDE生成的DAO还是自己写的DAO，代码大致如下：package mangerTeam.dao;import java.util.HashMap;import java.util.List;import javax.persistence.EntityManager;import javax.persistence.PersistenceException;import javax.persistence.Query;import mangerTeam.vo.PlayersVO;import org.springframework.context.ApplicationCont

14、ext;import org.springframework.orm.jpa.JpaCallback;import org.springframework.orm.jpa.support.JpaDaoSupport;import org.springframework.transaction.annotation.Transactional;Transactionalpublic class PlayerDAO extends JpaDaoSupport implements IPlayerDAO / property constants public static final String

15、NAME = ; public static final String MESS = public static final String PIC = public void save（PlayersVO entity） logger.info（saving Player instance）; try getJpaTemplate（）.persist（entity）; logger.info（save successful catch （RuntimeException re） logger.error（save failed, re）; throw re; public void delet

16、e（PlayersVO entity） deleting Player instance entity = getJpaTemplate（）.getReference（PlayersVO.class, entity.getId（）; getJpaTemplate（）.remove（entity）;delete successfuldelete failed public PlayersVO update（PlayersVO entity） updating Player instance PlayersVO result = getJpaTemplate（）.merge（entity）;upd

17、ate successful return result;update failed public PlayersVO findById（Integer id） finding Player instance with id: + id）; PlayersVO instance = getJpaTemplate（）.find（PlayersVO.class, id）; return instance;find failed SuppressWarnings（unchecked public List findByProperty（String propertyName, final Objec

18、t value, final int. rowStartIdxAndCount） finding Player instance with property: + propertyName + , value: + value）; final String queryString = select model from PlayersVO model where model. + propertyName + = :propertyValue return getJpaTemplate（）.executeFind（new JpaCallback（） public Object doInJpa（EntityManager em） throws PersistenceException Query query = em.createQuery（queryString）; query.setParameter（, value）; if （rowStartIdxAndCount != null & rowStartIdxAndCount.length 0） / 有分页 int rowStartIdx = Math.max（0, rowStartIdxAndCount0）; / 开始页 if （rowStartIdx
