自定义id生成器

 
 如主键要生成JXF001格式的，那么可以按如下方式配置：

 @Id
 @GenericGenerator(name="customGenerator",strategy="bap.core.domain.CustomIdGenerator",
  parameters = {
        @Parameter(name="prefix", value = "JXF"), //前缀
        @Parameter(name="initial_value", value="88"),//主键的初始值，如第一条记录的主键值为JXF088
        @Parameter(name="digit_number", value="3")//除前缀之外的数字位数，如：JXF001格式的位数为3，JXF00001格式的位数为5
 })
 @GeneratedValue(generator="customGenerator")
 private String id;
