JSF+Spring+JPA(Hibernate实现)的环境搭建（2）
在WEB-INF下面加入jsf_core.tld、html_basic.tld和tomahawk.taglib.xml文件、新建一个faces-config.xml文件，内容配置如下：
| <!--配置facelets--> <application> <locale-config> <default-locale>zh_CN</default-locale> </locale-config> <view-handler>com.sun.facelets.FaceletViewHandler</view-handler> </application>
<!—JSF与Spring集成--> <application> <variable-resolver> org.springframework.web.jsf.DelegatingVariableResolver </variable-resolver> </application> |
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-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">
<persistence-unit name="JSJDemoPU" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <class>test.vo.Test</class> <properties> <!-- 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 --> <property name="hibernate.show_sql" value="true" /> <!-- Hibernate 格式化sql --> <property name="hibernate.format_sql" value="true" /> <property name="hibernate.hbm2ddl.auto" value="update" /> </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 javax.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.ManyToOne; import javax.persistence.Table;
/** * 运动员实体 * * @author 刘岩 */ @Entity @Table(name = "player") public class PlayersVO implements Serializable {
@Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "id", unique = true, nullable = false) private Integer id;
@Column(name = "name") private String name;
@ManyToOne(optional=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) @Column(name = "pic") private byte[] pic;
@Lob @Basic(fetch = FetchType.LAZY) @Column(name = "mess") private String mess;
@ManyToMany(cascade = CascadeType.REFRESH, fetch = FetchType.LAZY) @JoinTable(name = "plays_position", joinColumns = { @JoinColumn(name = "playerId") }, inverseJoinColumns = { @JoinColumn(name = "positionId") }) private Set<PositionVO> positions;
public Integer getId() { return id; }
public void setId(Integer id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
public Set<PositionVO> getPositions() { return positions; }
public void setPositions(Set<PositionVO> positions) { this.positions = positions; }
public TeamVO getTeamVO() { return teamVO; }
public void setTeamVO(TeamVO teamVO) { this.teamVO = teamVO; }
public NationalityVO getNationalityVO() { 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; }
