JPA注解配置实例
以下收集了一些JPA常用的注解实例：@Entity@Table(name="ACCOUNT_INFO") public class ManagerAccountInfo implements Serializable { private static final long serialVersionUID = -1021341410178291401L; private Long id; private String loginAccount; private Date lastLoginDate; private ManagerOperator managerOperator; private Set<FrameworkAccountLevel> frameworkAccountLevels; private String officeNo; //标识字段 @Id @GeneratedValue(generator = "Cjm-Generator") @GenericGenerator(name = "Cjm-Generator", strategy = "com.cjm.core.utils.IdGenerator") @Column(name="id") public Long getId() { return id; } public void setId(Long id) { this.id = id; } //普通字段 @Column(name = "LOGIN_ACCOUNT") public String getLoginAccount() { return this.loginAccount; } public void setLoginAccount(String loginAccount) { this.loginAccount = loginAccount; } //日期字段 @Temporal(TemporalType.DATE) @Column(name = "LAST_LOGIN_DATE") public Date getLastLoginDate() { return this.lastLoginDate; } public void setLastLoginDate(Date lastLoginDate) { this.lastLoginDate = lastLoginDate; } //多对一 @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "MO_ID", referencedColumnName = "MO_ID") public ManagerOperator getManagerOperator() { return this.managerOperator; } public void setManagerOperator(ManagerOperator managerOperator) { this.managerOperator = managerOperator; } //一对多 @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "managerAccountInfo") public Set<FrameworkAccountLevel> getFrameworkAccountLevels() { return this.frameworkAccountLevels; } public void setFrameworkAccountLevels( Set<FrameworkAccountLevel> frameworkAccountLevels) { this.frameworkAccountLevels = frameworkAccountLevels; } //非持久化字段 @Transient public String getOfficeNo() { return officeNo; } public void setOfficeNo(String officeNo) { this.officeNo = officeNo; } }
