SpringDataJpa 分页查询

第一种方式

 

实体类

Student

import javax.persistence.*;
import java.io.Serializable;

@Entity
@Table(name="Student")
public class Student implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)//自动增长主键
    @Column(name = "stuid")
    private int stuId;
    @Column(name = "stuname")
    private String stuName;
    @Column(name = "stusex")
    private String stuSex;
    @Column(name = "stuage")
    private String stuAge;

    public Student(){}

    public Student(String stuName) {
        this.stuName = stuName;
    }

    public int getStuId() {
        return stuId;
    }

    public void setStuId(int stuId) {
        this.stuId = stuId;
    }

    public String getStuName() {
        return stuName;
    }

    public void setStuName(String stuName) {
        this.stuName = stuName;
    }

    public String getStuSex() {
        return stuSex;
    }

    public void setStuSex(String stuSex) {
        this.stuSex = stuSex;
    }

    public String getStuAge() {
        return stuAge;
    }

    public void setStuAge(String stuAge) {
        this.stuAge = stuAge;
    }


    @Override
    public String toString() {
        return "Student{" +
                "stuId=" + stuId +
                ", stuName='" + stuName + '\'' +
                ", stuSex='" + stuSex + '\'' +
                ", stuAge='" + stuAge + '\'' +
                '}';
    }
}

dao

import com.oukele.demo1.oyl.entity.Student;
import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.jpa.repository.QueryHints;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;

import javax.persistence.QueryHint;
import java.util.List;

import static org.hibernate.jpa.QueryHints.HINT_COMMENT;


public interface StudentDao extends CrudRepository<Student, Long> {

    @QueryHints(value = { @QueryHint(name = HINT_COMMENT, value = "a query for pageable")})
    @Query(value = " select * from student",nativeQuery = true)
    Page<Student> getPageList(Pageable pageable);

}

测试类

@Autowired
private StudentDao studentDao;

@Test
public void getPageList(){
 Pageable pageable = new PageRequest(0,3);

 Page<Student> pageList = studentDao.getPageList(pageable);

 for (Student student : pageList.getContent()) {
 System.out.println(student);
 }
}
