这篇文章给大家介绍怎么在VUE中使用SpringBoot实现分页功能,内容非常详细,感兴趣的小伙伴们可以参考借鉴,希望对大家能有所帮助。
VUE之视图定义
<el-row> <el-table :data="tableData" > <el-table-column v-for="(data,index) in tableHeader" :key="index" :prop="data.prop" :label="data.label" :min-width="data['min-width']" :align="data.align"> </el-table-column> <el-table-column label="操作" min-width="240"> <template slot-scope="scope"> <el-button type="success" size="mini" @click="toRecharge(scope)">充值</el-button> <el-button size="mini" @click="toView(scope)">查看</el-button> <el-button type="primary" size="mini" @click="toEdit(scope)">修改</el-button> <el-button type="danger" size="mini" @click="deleteCard(scope)">删除</el-button> </template> </el-table-column> </el-table> <br> <el-pagination @size-change="handleSizeChange" @current-change="handleCurrentChange" :current-page="pagination.pageIndex" :page-sizes="[5, 10, 20, 30, 40]" :page-size=pagination.pageSize layout="total, sizes, prev, pager, next, jumper" :total=pagination.total> </el-pagination> </el-row>
重点说明:
数据类型定义:
tableData:定义后台数据模型定义。
tableHeader:定义表格与后台数据绑定关系。
pagination:定义分页数据模型,主要包含(pageIndex:当前页,pageSize:页大小, total:总记录数)
方法定义:
handleSizeChange:更新页大小
handleCurrentChange:更新当前页
VUE之模型定义(data)
tableData: [], pagination: { pageIndex: 1, pageSize: 10, total: 0, }, tableHeader: [ { prop: 'sid', label: '编号', align: 'left' }, { prop: 'password', label: '密码', align: 'left' }, { prop: 'state', label: '状态', align: 'left' }, { prop: 'money', label: '金额', align: 'left' }, { prop: 'studentSid', label: '学生SID', align: 'left' } ]
VUE之数据初始化
VUE 方法定义:请求后台数据接口加载相关数据(method)
init () { var self = this this.$axios({ method:'post', url:'/card/findPage', data:{"page":this.pagination.pageIndex,"limit":this.pagination.pageSize}, headers:{ 'Content-Type':'application/json;charset=utf-8' //改这里就好了 } }).then(res => { console.log(res); self.pagination.total = res.data.data.total_count; self.tableData = res.data.data.list; }) .catch(function (error) { console.log(error) }) }, handleSizeChange(val) { this.pagination.pageSize = val; this.pagination.pageIndex = 1; this.init(); }, handleCurrentChange(val) { this.pagination.pageIndex = val; this.init(); },
VUE 声明周期函数定义:调用VUE的方法定义,完成数据初始化过程.
在VUE声明周期函数mounted ()中,调用init ,完成数据初始化过程。
mounted: function () { this.init() }
entity 定义
package com.zzg.entity; import java.math.BigDecimal; import java.util.Date; import org.springframework.format.annotation.DateTimeFormat; import com.fasterxml.jackson.annotation.JsonFormat; import com.zzg.common.BaseModel; public class TCard extends BaseModel { /** * */ private static final long serialVersionUID = 1035674221133528445L; private Integer sid; private String password; private String state; private BigDecimal money; @DateTimeFormat(pattern="yyyy-MM-dd") @JsonFormat(pattern="yyyy-MM-dd",timezone="GMT+8") private Date starTime; @DateTimeFormat(pattern="yyyy-MM-dd") @JsonFormat(pattern="yyyy-MM-dd",timezone="GMT+8") private Date endTime; private Integer studentSid; public Integer getSid() { return sid; } public void setSid(Integer sid) { this.sid = sid; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password == null ? null : password.trim(); } public String getState() { return state; } public void setState(String state) { this.state = state == null ? null : state.trim(); } public BigDecimal getMoney() { return money; } public void setMoney(BigDecimal money) { this.money = money; } public Date getStarTime() { return starTime; } public void setStarTime(Date starTime) { this.starTime = starTime; } public Date getEndTime() { return endTime; } public void setEndTime(Date endTime) { this.endTime = endTime; } public Integer getStudentSid() { return studentSid; } public void setStudentSid(Integer studentSid) { this.studentSid = studentSid; } }
mapper定义
package com.zzg.mapper; import java.util.List; import java.util.Map; import com.zzg.entity.TCard; public interface TCardMapper { int deleteByPrimaryKey(Integer sid); int insert(TCard record); int insertSelective(TCard record); TCard selectByPrimaryKey(Integer sid); int updateByPrimaryKeySelective(TCard record); int updateByPrimaryKey(TCard record); /** * 方法拓展 */ List<TCard> select(Map<String, Object> parame); Integer count(Map<String, Object> parame); void batchInsert(List<TCard> list); void batchUpdate(List<TCard> list); }
