枚举类型

枚举类型实例

枚举实体

public enum AuthorityType {
不可见, 
只读,
可读写
}

权限实体

@Entity
@Table(name = "Permission")
 public class Permission extends BaseEntity {
private static final long serialVersionUID = -5067770823940934837L;
/**
 * 角色
 */
private Role role;
/**
 * 模块信息
 */
private ModelResources model;

/**
 * 权限
 */
private AuthorityType authorityType;

/**
 * 附加属性
 */
private String  attachAttr;

@JsonIgnore
@ManyToOne(fetch=FetchType.LAZY)
public Role getRole() {
	return role;
}

public void setRole(Role role) {
	this.role = role;
}

**@Enumerated(EnumType.ORDINAL)**
@Column()
public AuthorityType getAuthorityType() {
	return authorityType;
}

public void setAuthorityType(AuthorityType authorityType) {
	this.authorityType = authorityType;
}

public String getAttachAttr() {
	return attachAttr;
}

public void setAttachAttr(String attachAttr) {
	this.attachAttr = attachAttr;
}


@ManyToOne(fetch=FetchType.LAZY)
@JsonIgnoreProperties(value={"hibernateLazyInitializer","handler","fieldHandler"}) 
public ModelResources getModel() {
	return model;
}

public void setModel(ModelResources model) {
	this.model = model;
}
}

@Enumerated(EnumType.ORDINAL) 采用枚举类型的序号值与数据库进行交互
序号从零开始
赋值方式 ：permissionmodel.setAuthorityType(AuthorityType.不可见);
