Spring配置：集成Hibernate、JacksonJSON、AspectJ等框架
本文提及的该套配置文件，覆盖了JavaEE项目开发的最常见需求，包括：依赖注入、事务控制、AOP、任务调度、缓存、MVC框架等方面的内容。
容易改变的配置项独立到属性文件中：
Spring配置文件部分：
Spring MVC配置文件部分：
ehcache配置部分：
Web.xml配置（使用了Spring的JavaConfig）：
Java Config类：

Hibernate基于注解的配置样例
实体类上的常用注解
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
@Entity ( name = "ChristmasTree" ) @Table ( name = "T_CRISMS_TREE" ) //给自动生成的表添加注释 @org.hibernate.annotations.Table ( appliesTo = "T_CRISMS_TREE", comment = "圣诞树" ) @Cacheable //JPA注解，表示该类型的实体支持缓存 //启用二级缓存时有意义，指定Hibernate缓存策略、存放区域 @Cache ( usage = CacheConcurrencyStrategy.READ_WRITE, region = "entityCache" ) public class ChristmasTree { //集合属性的缓存策略必须单独配置 @Cache ( usage = CacheConcurrencyStrategy.READ_WRITE, region = "entityCache" ) private List branches; } |
使用注解方式进行对象-数据库映射时，应当以JPA注解为主，仅Hibernate特有的功能则使用其私有的注解类。
简单主键和简单属性映射

//简单的主键映射 @Id //该注解指明此实体的标识符属性，对应了关系型数据库的主键 @Column ( name = "ID", columnDefinition = "int(11) comment '主键'" ) private Integer id; //UUID方式的主键生成器配置，其它任何自定义的主键生成器可以依样扩展 @Id @Column ( name = "ID", columnDefinition = "varchar(36) comment '主键,36位UUID'" ) @GeneratedValue ( generator = "uuid" ) @GenericGenerator ( name = "uuid", strategy = "org.hibernate.id.UUIDGenerator" ) private String id; //可以指定普通属性的延迟加载 @Basic ( fetch = FetchType.EAGER, optional = true ) @Column ( name = "BUILD_COST", columnDefinition = "decimal(10,2) comment '建造费用'" ) private BigDecimal buildCost; //时间映射 //只能用于java.util.Date或者java.util.Calendar，用于表示日期、时间或者时间戳 @Temporal ( TemporalType.TIMESTAMP ) @Column ( name = "BUILD_TIME", columnDefinition = "datetime comment '建造时间'" ) private Date buildTime; //大字段映射 @Lob @Column ( name = "REMARK", columnDefinition = "longtext comment '圣诞树备注信息'" ) private String remark; //枚举类型映射 @Enumerated ( EnumType.ORDINAL ) //根据枚举元素的声明顺序，从0开始 @Column ( name = "STATUS", columnDefinition = "tinyint comment '状态'" ) private Status status; //乐观并发控制用列 @Version @Column ( name = "VERSION" ) public Integer version; |
