新增电子书表单

主要是对admin-book.vue进行修改。

点击编辑按钮，弹出对话框，这里使用Antd的Modal组件

<template>
  <a-layout>
    <a-layout-content
        :style="{ background: '#fff', padding: '24px', margin: 0, minHeight: '280px' }"
    >
      <a-table :columns="columns" 
        :dataSource="ebooks"
        :row-key="record=>record.id"
        :pagination="pagination"
        :loading="loading"
        @change="handleTableChange">
        <template #cover="{text:cover}">
          <img v-if="cover" :src="cover" alt="avatar">
        </template>
        <template #action="{text,record}">
          <a-space>
            <a-button type="primary" @click="handleEdit">编辑</a-button>
            <a-button type="danger">删除</a-button>
          </a-space>
        </template>
      </a-table>
    </a-layout-content>

  </a-layout>

  <a-modal
    title="电子书表单"
    v-model:visible="visible"
    :confirm-loading="confirmLoading"
    @ok="handleOk"
  >
    <p>{{ modalText }}</p>
  </a-modal>

</template>


<script lang="ts">

弹出的对话框，框中内容是表单，所以使用Antd的Form组件

<template>
  <a-layout>
    <a-layout-content
        :style="{ background: '#fff', padding: '24px', margin: 0, minHeight: '280px' }"
    >
      <a-table :columns="columns" 
        :dataSource="ebooks"
        :row-key="record=>record.id"
        :pagination="pagination"
        :loading="loading"
        @change="handleTableChange">
        <template #cover="{text:cover}">
          <img v-if="cover" :src="cover" alt="avatar">
        </template>
        <template #action="{text,record}">
          <a-space>
            <a-button type="primary" @click="handleEdit(record)">编辑</a-button>
            <a-button type="danger">删除</a-button>
          </a-space>
        </template>
      </a-table>
    </a-layout-content>

完成电子书编辑功能

新增并测试后端接口

修改电子书属性后，点击OK按钮，保存，对此，需要新增后端接口。

在com.jepcc.test.req包下新增类EbookSaveReq，

package com.jepcc.test.req;

public class EbookSaveReq {
    private Long id;

    private String name;

    private Long category1Id;

    private Long category2Id;

    private String description;

    private String cover;

    private Integer docCount;

    private Integer viewCount;

    private Integer voteCount;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Long getCategory1Id() {
        return category1Id;
    }

    public void setCategory1Id(Long category1Id) {
        this.category1Id = category1Id;
    }

    public Long getCategory2Id() {
        return category2Id;
    }

    public void setCategory2Id(Long category2Id) {
        this.category2Id = category2Id;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public String getCover() {
        return cover;
    }

    public void setCover(String cover) {
        this.cover = cover;
    }

    public Integer getDocCount() {
        return docCount;
    }

    public void setDocCount(Integer docCount) {
        this.docCount = docCount;
    }

    public Integer getViewCount() {
        return viewCount;
    }

    public void setViewCount(Integer viewCount) {
        this.viewCount = viewCount;
    }

    public Integer getVoteCount() {
        return voteCount;
    }

    public void setVoteCount(Integer voteCount) {
        this.voteCount = voteCount;
    }
}

在com.jepcc.test.service.EbookService中添加保存方法

package com.jepcc.test.service;

import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import com.jepcc.test.mapper.EbookMapper;
import com.jepcc.test.model.Ebook;

import java.util.List;


@Service
public class EbookService {
    private static final Logger LOG = LoggerFactory.getLogger(EbookService.class);
    @Autowired
    private EbookMapper ebookMapper;
    public PageResp<EbookResp> list(EbookReq req){

        EbookExample ebookExample = new EbookExample();
        EbookExample.Criteria criteria = ebookExample.or();
        if(!ObjectUtils.isEmpty(req.getName())){
            criteria.andNameLike("%"+req.getName()+"%");
        }

        PageHelper.startPage(req.getPage(),req.getSize());
        List<Ebook> ebookList = ebookMapper.selectByExample(ebookExample);

        PageInfo<Ebook> pageinfo = new PageInfo<>(ebookList);
//        LOG.info("总条数：{}",pageinfo.getTotal());
//        LOG.info("总页数，{}",pageinfo.getPages());
        List<EbookResp> list = CopyUtil.copyList(ebookList,EbookResp.class);
        PageResp<EbookResp> pageResp = new PageResp<>();
        pageResp.setTotal(pageinfo.getTotal());
        pageResp.setList(list);

        return pageResp;
    }

    public void save(EbookSaveReq req){
        Ebook ebook = CopyUtil.copy(req,Ebook.class);
        if(!ObjectUtils.isEmpty(ebook.getId())){
            ebookMapper.updateByPrimaryKey(ebook);
        }
    }
}

在com.jepcc.test.controller.EbookController新增保存方法

package com.jepcc.test.controller;

import com.alibaba.fastjson.JSONObject;
import com.jepcc.test.req.EbookReq;
import com.jepcc.test.req.EbookSaveReq;
import com.jepcc.test.resp.CommonResp;
import com.jepcc.test.resp.EbookResp;
import com.jepcc.test.resp.PageResp;
import com.jepcc.test.service.EbookService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

@RestController
@RequestMapping("/ebook")
public class EbookController {
    private static final Logger LOG = LoggerFactory.getLogger(EbookController.class);
    @Autowired
    private EbookService ebookService;


    @GetMapping("/list")
    public CommonResp list(EbookReq req){
        CommonResp resp = new CommonResp();
        PageResp<EbookResp> list = ebookService.list(req);
        resp.setContent(list);
        return resp;
    }

    @PostMapping("/save")
    public CommonResp save(@RequestBody EbookSaveReq req){
        LOG.info("----------------------------------------");
        LOG.info("req:{}", JSONObject.toJSONString(req));
        LOG.info("----------------------------------------");
        CommonResp resp = new CommonResp();
        ebookService.save(req);
        return resp;
    }
}

接口测试

POST http://localhost:8088/ebook/save
content-type: application/json

{
  "id": 1,
  "name": "SpringBoot入门教程",
  "category1Id": 10,
  "category2Id": 20,
  "cover": "/image/cover1.png",
  "description": "这是一项测试"
}
###

在这里插入图片描述

需要注意的是，如果http请求的Content-Type是application/json，则EbookController中的接口方法save，其参数前需要添加@RequestBody注解；

如果http请求的Content-Type是application/x-www-form-urlencoded，则EbookController中的接口方法save中，其请求参数前不需要@RequestBody。
在这里插入图片描述
后端使用@RequestBody接收从前端传递过来的json字符串，通常是通过post请求发送过来的请求体数据。

前端调用接口

对admin-book.vue进行修改。
