dao层：@Repository(value ="")或者@Component(value="")
service层：@Service(value ="")或者@Component(value="")
           有关事务的配置：
    @Transactional(propagation=Propagation.REQUIRED)（更新）
    @Transactional(propagation=Propagation.SUPPORTS)（查询）
action层：@Controller(value="")，@Scope("prototype") （配置为多例）
注入：@Autowired，@Resource

实体类中的配置：
类之前：
@Entity(name="User")
@Table(name="xs_user")
@Cache(usage = CacheConcurrencyStrategy.TRANSACTIONAL)
@IdClass(value=AgencyFunctionInfoRoleAssociate.class)

id 前的配置：
@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name = "id", nullable = false)
private Integer id;
有关时间的配置：
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "create_time", nullable = false)
private Date createTime;
用到枚举是的配置:
@Enumerated(EnumType.STRING)
@Column(name = "active_type", nullable = false, length = 32)
private ActiveType activeType;
一般的配置：
@Column(name = "comments", nullable = false, length = 128)
private String comments;
@Column(name = "comments", nullable = false, length = 256)
private String comments;
内容较多时：
@Column(name = "affiche_content", nullable = false, columnDefinition="TEXT")
private String afficheContent;
Boolean型：
@Column(name = "is_enable", nullable = false)
private Boolean enable;

有关于唯一：
@Column(name = "logogram_name", nullable = false, unique = true, length = 16)
private String logogramName;
有默认值时：
@Column(name = "already_guaranted_count", nullable = false, columnDefinition = "int DEFAULT 0")
private Integer alreadyGuarantedPhasesCount;
double类型的处理：
@Column(name = "already_guaranted_amount", scale = 2, precision = 16, columnDefinition = "decimal(16,2) DEFAULT 0", nullable = false)
private Double alreadyGuarantedAmount;


@Column(name="birthday")
@ManyToOne
@JoinColumn(name="c_id")

一对一的配置：
@OneToOne(optional = false, targetEntity = com.zhang.model.activities.Award.class, cascade = { CascadeType.DETACH }, fetch = FetchType.LAZY)
@JoinColumn(name = "award_id", unique = false, nullable = false)
private Award award;
多对多的配置：
@ManyToMany(targetEntity = com.zhang.model.agency.AgencyRole.class, cascade = { CascadeType.ALL }, fetch = FetchType.EAGER)
@JoinTable(name = "rbac_agency_role_associate", joinColumns = @JoinColumn(name = "agency_id"), inverseJoinColumns = @JoinColumn(name = "agency_role_id"))
private Set<AgencyRole> roles;

@ManyToMany(targetEntity = com.zhang.model.agency.AgencyFunctionInfo.class, cascade = { CascadeType.ALL }, fetch = FetchType.EAGER)
private Set<AgencyFunctionInfo> agencyFunctionInfos;

@ManyToMany(targetEntity = com.zhang.model.agency.AgencyRole.class, cascade = { CascadeType.ALL }, fetch = FetchType.EAGER)
@JoinTable(name = "agency_role_staff_associate", joinColumns = @JoinColumn(name = "agency_staff_id"), inverseJoinColumns = @JoinColumn(name = "agency_role_id"))
private Set<AgencyRole> agencyRoles;
多对一的配置：
@ManyToOne(targetEntity = com.zhang.model.agency.Agency.class, optional = true,cascade={CascadeType.REFRESH})
@JoinColumn(name = "agency_id", nullable = false)
private Agency agency;

@ManyToOne(targetEntity = com.zhang.model.agency.Agency.class, optional = true,cascade={CascadeType.REFRESH})
@JoinColumn(name = "agency_id", nullable = false)
private Agency agency;

@ManyToOne(targetEntity = com.zhang.model.agency.AgencyDepart.class, optional = true,cascade={CascadeType.REFRESH})
@JoinColumn(name = "agency_depart", nullable = false)
private AgencyDepart agencyDepart;

@ManyToOne(targetEntity = com.zhang.model.agency.Agency.class, optional = true, cascade = { CascadeType.REFRESH })
@JoinColumn(name = "agency_id", nullable = false)
private Agency agency;
一对多的配置：
@OneToMany(targetEntity = AgencyFunctionInfo.class, cascade = { CascadeType.REFRESH }, fetch = FetchType.EAGER,mappedBy="parentId")
private List<AgencyFunctionInfo> children;

@OneToMany(targetEntity = ProductParamter.class, cascade = {CascadeType.PERSIST, CascadeType.REFRESH }, fetch = FetchType.EAGER)
private Set<ProductParamter> paramters;
