Question

如何在带分页的jpa spring boot中使用HashMap>作为查询参数

Answer 1

是的，这是可能的。您可以在查询中使用 Spring 表达式语言。

示例：

@Query("select e from Employee e where e.name = :#{#map.get('name')}")
List<Employee> findEmployees(Map<String, String> map);

甚至更短

@Query("select e from Employee e where e.name = :#{#map['name']}")
List<Employee> findEmployees(Map<String, String> map);

也适用于 IN

@Query("select e from Employee e where e.name in :#{#map['name']}")
List<Employee> findEmployees(Map<String, List<String>> map);
