repository中使用@Query注解使用hql查询，使用@Param引用参数

如题报错：

代码如下：

package com.sxd.sweeping.repository;

import com.sxd.sweeping.entity.User;

import org.apache.ibatis.annotations.Param;

import org.springframework.data.domain.Page;

import org.springframework.data.domain.Pageable;

import org.springframework.data.jpa.repository.JpaRepository;

import org.springframework.data.jpa.repository.Query;

import java.sql.Date;

public interface UserRepository extends JpaRepository<User,Long> {

    User findUserById(Long id);

    @Query(value = "select u from User u " +

            "where :keyword is null or u.realname like %:keyword% " +

            "and (u.updateAt between :startDate and :endDate)")

    Page<User> pageList(

            @Param("keyword") String keyword,

            @Param("startDate") Date startDate,

            @Param("endDate") Date endDate,

            Pageable pageable);

}

错误解析：

明显能看出来，这个错误是因为hql这里和@Param的原因导致的错误，错误提示hql中的字段值应该使用@Param()注解标志的字段。

但是上面的代码中明明已经使用了呀。

解决问题：

最后发现问题在于，确实使用了@Param注解，但是却引错了架包。

对于hql和代码无需任何的改动，只需要将import更改即可

import org.springframework.data.repository.query.Param;
package com.sxd.sweeping.repository;

import com.sxd.sweeping.entity.User;

import org.springframework.data.domain.Page;

import org.springframework.data.domain.Pageable;

import org.springframework.data.jpa.repository.JpaRepository;

import org.springframework.data.jpa.repository.Query;

import org.springframework.data.repository.query.Param;

import java.sql.Date;

public interface UserRepository extends JpaRepository<User,Long> {

    User findUserById(Long id);

    @Query(value = "select u from User u " +

            "where :keyword is null or u.realname like %:keyword% " +

            "and (u.updateAt between :startDate and :endDate)")

    Page<User> pageList(

            @Param("keyword") String keyword,

            @Param("startDate") Date startDate,

            @Param("endDate") Date endDate,

            Pageable pageable);

}
