这篇文章主要为大家展示了“Spring MVC结合Spring Data JPA如何实现按条件查询和分页功能”，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下“Spring MVC结合Spring Data JPA如何实现按条件查询和分页功能”这篇文章吧。
具体内容如下
后台代码：在DAO层继承Spring Data JPA的PagingAndSortingRepository接口实现的 （实现方法主要在SbglServiceImpl.java类中）
前台表现：用kkpaper表现出来
实现效果：
1、实体类
package com.jinhetech.yogurt.sbgl.entity;
import java.io.Serializable;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.PrimaryKeyJoinColumn;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;
import org.hibernate.annotations.GenericGenerator;
import org.springframework.cache.annotation.Cacheable;
@Entity
@Table(name="SYS_SBGL")
@PrimaryKeyJoinColumn(name = "SBBM")
@Cacheable(value = "baseCache")
public class Sbgl implements Serializable{
private static final long serialVersionUID = -1423899016746755470L;
@Id
private String sbbm;
private String sbmc;
private String sblx;
private String sssx;
private String ssjd;
private String azsj;
private String azry;
private String sbzt;
private String sbjd;
private String sbwd;
private String wxlxr;
private String wxlxdh;
private String sbywxcs;
private String jzpylyz;
private String mqsbcyr;
private String bzsm;
//setter、getter方法省略
}2、jsp页面，看最下面的分页组件（kkpaper）
resultMap集合是下面Controller中最后查询和分页后获得的所有数据信息，resultMap.resultList：resultList是Map集合的属性，里面存着<key,value>数据
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core_rt" %>

}4、DAO（SbglDao.java）,对，只需要继承Spring Data JPA的PagingAndSortingRepository接口，Controller中调用其findAll()方法
package com.jinhetech.yogurt.sbgl.dao;
import org.springframework.data.jpa.repository.JpaSpecificationExecutor;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.PagingAndSortingRepository;
import org.springframework.stereotype.Repository;
import com.jinhetech.yogurt.sbgl.entity.Sbgl;
import com.jinhetech.yogurt.user.entity.UserInfo;
@Repository("sbglDao")
public interface SbglDao extends PagingAndSortingRepository<Sbgl, String>, JpaSpecificationExecutor<Sbgl> {
