-/**
- * 标记不可变对象。根据约定，该对象的字段只能是不可变对象或基础数据类型，且都是只读的。如：
- * <pre>@ImmutableObject
- * class Foo {
- *     private final @Getter int intVal;
- *     private final @Getter String stringVal;
- *     private final @Getter LocalDate dateVal;
- *     private final @Getter BigDecimal decimalVal;
- * }
- * </pre>
- * <p>
- * 如 guava 的 ImmutableList、ImmutableMap 等不可变集合，不属于此，因为其不要求包含的元素本身是不可变的。
