java JPA 查询 between and 问题

Question

javax.persistence.criteria.CriteriaBuilder这个类的这个方法怎么用啊，看晕了。。求助。

/**
	 * Create a predicate for testing whether the first argument is
	 * between the second and third arguments in value.
	 *
	 * @param v expression
	 * @param x expression
	 * @param y expression
	 *
	 * @return between predicate
	 */
	<Y extends Comparable<? super Y>> Predicate between(Expression<? extends Y> v, Expression<? extends Y> x, Expression<? extends Y> y);

Answer 1

restrictions = criteriaBuilder.and(restrictions,

criteriaBuilder.between(root.<String> get(filter.getProperty()),date1, date2));

已经解决了，根据红色的类型，确定后面传入的参数类型
