一、列表界面展示示例
现在要做的就是把打到页面的数据，带样式，也就是说好看点显示。
之前我们在《Vue3（二）集成Ant Design Vue》这篇文章中，有提及组件的使用，对于一个前端不是很好（后端也不咋的），本着拿来主义，我们能现成的是最好、最省事的方式了。
直白点说就是，找Ant Design Vue现成的组件，将列表数据按组件样式显示到界面上。
1、挑选自己喜欢的列表样式
从https://2x.antdv.com/components/list-cn中，找到list列表，找到自己喜欢的风格，
如下图所示：
2、进行数据显示
2.1、组件在列表显示
接下来，我们只需要在home里进行修改即可，找到刚才对应组件的位置，把对应代码拷贝到home中，然后在进行修改即可，
示例代码如下：
<template>
<a-layout>
<a-layout-sider width="200" style="background: #fff">
<a-menu
mode="inline"
v-model:selectedKeys="selectedKeys2"
v-model:openKeys="openKeys"
:style="{ height: '100%', borderRight: 0 }"
>
<a-sub-menu key="sub1">
<template #title>
<span>
<user-outlined />
subnav 1
</span>
</template>
<a-menu-item key="1">option1</a-menu-item>
<a-menu-item key="2">option2</a-menu-item>
<a-menu-item key="3">option3</a-menu-item>
<a-menu-item key="4">option4</a-menu-item>
</a-sub-menu>
<a-sub-menu key="sub2">
<template #title>
<span>
<laptop-outlined />
subnav 2
</span>
</template>
<a-menu-item key="5">option5</a-menu-item>
<a-menu-item key="6">option6</a-menu-item>
<a-menu-item key="7">option7</a-menu-item>
<a-menu-item key="8">option8</a-menu-item>
</a-sub-menu>
<a-sub-menu key="sub3">
<template #title>
<span>
<notification-outlined />
subnav 3
</span>
</template>
<a-menu-item key="9">option9</a-menu-item>
<a-menu-item key="10">option10</a-menu-item>
<a-menu-item key="11">option11</a-menu-item>
<a-menu-item key="12">option12</a-menu-item>
</a-sub-menu>
</a-menu>
</a-layout-sider>
<a-list item-layout="vertical" size="large" :pagination="pagination" :data-source="listData">
<template #footer>
<div>
<b>ant design vue</b>
footer part
</div>
</template>
<template #renderItem="{ item }">
<a-list-item key="item.title">
<template #actions>
<span v-for="{ type, text } in actions" :key="type">
<component v-bind:is="type" style="margin-right: 8px" />
{{ text }}
</span>
</template>
<template #extra>
<img
width="272"
alt="logo"
src="https://gw.alipayobjects.com/zos/rmsportal/mqaQswcyDLcXyDKnZfES.png"
/>
</template>
<a-list-item-meta :description="item.description">
<template #title>
<a :href="item.href" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >{{ item.title }}</a>
</template>
<template #avatar><a-avatar :src="item.avatar" /></template>
</a-list-item-meta>
{{ item.content }}
</a-list-item>
</template>
</a-list>
</a-layout>
</template>
<script lang="ts">
import { defineComponent,onMounted,ref,reactive,toRef} from 'vue';
import axios from 'axios';
import { StarOutlined, LikeOutlined, MessageOutlined } from '@ant-design/icons-vue';
const listData: Record<string, string>[] = [];
for (let i = 0; i < 23; i++) {
listData.push({
href: 'https://www.antdv.com/',
title: `ant design vue part ${i}`,
avatar: 'https://zos.alipayobjects.com/rmsportal/ODTLcjxAfvqbxHnVXCYX.png',

content:
'We supply a series of design principles, practical patterns and high quality design resources (Sketch and Axure), to help people create their product prototypes beautifully and efficiently.',
});
}
export default defineComponent({
components: {
StarOutlined,
LikeOutlined,
MessageOutlined,
},
name: 'Home',
setup(){
const pagination = {
onChange: (page: number) => {
console.log(page);
},
pageSize: 3,
};
const actions: Record<string, string>[] = [
{ type: 'StarOutlined', text: '156' },
{ type: 'LikeOutlined', text: '156' },
{ type: 'MessageOutlined', text: '2' },
];
console.log('set up');
//使用ref进行数据绑定
const ebooks=ref();
// 使用reactive进行数据绑定
const ebooks1=reactive({books:[]})
onMounted(()=>{
axios.get("http://localhost:8888/ebook/list?name=spring").then(response =>{
console.log("onMounted");
const data=response.data;
ebooks.value=data.content;
ebooks1.books=data.content;
})
})
return{
listData,
pagination,
actions,
ebooks1: ebooks,
ebooks2:toRef(ebooks1,"books")
}
}
});
</script>
重新编译运行，查看效果如下：
2.2、接口返回数据在列表显示
明显现在，可以看到想要用的列表样式已经在页面中成功展示了，但这并不是我想要的，我想要的是后端接口返回数据在此处展示，也就是数据源，接下来,我们再次调整Home的代码，
示例代码如下：
<template>
<a-layout>
`<a-layout-sider width="200" style="background: #fff">
<a-menu
mode="inline"
v-model:selectedKeys="selectedKeys2"
v-model:openKeys="openKeys"
:style="{ height: '100%', borderRight: 0 }"
>
<a-sub-menu key="sub1">
<template #title>
<span>
<user-outlined />
subnav 1
</span>
</template>
<a-menu-item key="1">option1</a-menu-item>
<a-menu-item key="2">option2</a-menu-item>
<a-menu-item key="3">option3</a-menu-item>
<a-menu-item key="4">option4</a-menu-item>
</a-sub-menu>
<a-sub-menu key="sub2">
<template #title>
<span>
<laptop-outlined />
subnav 2
</span>
</template>
<a-menu-item key="5">option5</a-menu-item>
<a-menu-item key="6">option6</a-menu-item>
<a-menu-item key="7">option7</a-menu-item>
<a-menu-item key="8">option8</a-menu-item>
</a-sub-menu>
<a-sub-menu key="sub3">
<template #title>
<span>
<notification-outlined />
subnav 3
</span>
</template>
<a-menu-item key="9">option9</a-menu-item>
<a-menu-item key="10">option10</a-menu-item>
<a-menu-item key="11">option11</a-menu-item>
<a-menu-item key="12">option12</a-menu-item>
</a-sub-menu>
</a-menu>
</a-layout-sider>`
<a-list item-layout="vertical" size="large" :pagination="pagination" :data-source="ebooks1">
<template #renderItem="{ item }">
<a-list-item key="item.name">
<template #actions>
<span v-for="{ type, text } in actions" :key="type">
<component v-bind:is="type" style="margin-right: 8px" />
{{ text }}
</span>
</template>
<a-list-item-meta :description="item.description">
<template #title>
<a :href="item.href" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >{{ item.name }}</a>
</template>
<template #avatar><a-avatar :src="item.cover" /></template>
</a-list-item-meta>
</a-list-item>
</template>
</a-list>
</a-layout>
</template>
<script lang="ts">
import { defineComponent,onMounted,ref,reactive,toRef} from 'vue';
import axios from 'axios';
import { StarOutlined, LikeOutlined, MessageOutlined } from '@ant-design/icons-vue';
const listData: Record<string, string>[] = [];
for (let i = 0; i < 23; i++) {
listData.push({
href: 'https://www.antdv.com/',

content:

});
}
export default defineComponent({
components: {
StarOutlined,
LikeOutlined,
MessageOutlined,
},
name: 'Home',
setup(){
const pagination = {
onChange: (page: number) => {
console.log(page);
},
pageSize: 3,
};
const actions: Record<string, string>[] = [
{ type: 'StarOutlined', text: '156' },
{ type: 'LikeOutlined', text: '156' },
{ type: 'MessageOutlined', text: '2' },
];
console.log('set up');
//使用ref进行数据绑定
const ebooks=ref();
// 使用reactive进行数据绑定
const ebooks1=reactive({books:[]})
onMounted(()=>{
axios.get("http://localhost:8888/ebook/list?name=spring").then(response =>{
console.log("onMounted");
const data=response.data;
ebooks.value=data.content;
ebooks1.books=data.content;
})
})
return{
listData,
pagination,
actions,
ebooks1: ebooks,
ebooks2:toRef(ebooks1,"books")
}
}
});
</script>
<style>
.ant-layout-sider{
float: left;
}
</style>
重新编译运行，查看效果如下：
2.3、接口数据改造
很明显，列表数据太少，我对接口进行改造，让其返回多条数据。
我们从service中，不难看出我们做的是，不管传入什么，都是写死的走的模糊查询，这里我们改成动态SQL即可，
示例代码如下：
package com.rongrong.wiki.service;
import com.rongrong.wiki.domain.EBook;
import com.rongrong.wiki.domain.EBookExample;
import com.rongrong.wiki.mapper.EBookMapper;
import com.rongrong.wiki.req.EBookReq;
import com.rongrong.wiki.resp.EBookResp;
import org.springframework.stereotype.Service;
import org.springframework.util.ObjectUtils;
import javax.annotation.Resource;
import java.util.List;
import static com.rongrong.wiki.util.CopyUtil.copyList;
/**
* @author rongrong
* @version 1.0
* @description
* @date 2021/10/13 23:09
*/
@Service
public class EBookService {
@Resource
private EBookMapper eBookMapper;
public List<EBookResp> list(EBookReq eBookReq) {
EBookExample eBookExample = new EBookExample();
//此处代码的意思相当于，搞了一个Sql的where条件
EBookExample.Criteria criteria = eBookExample.createCriteria();
//划波浪线为不推荐使用，这里我们去看源代码做个替换即可
if(!ObjectUtils.isEmpty(eBookReq.getName())){
criteria.andNameLike("%"+eBookReq.getName()+"%");
}
List<EBook> eBookList = eBookMapper.selectByExample(eBookExample);
//List<EBookResp> eBookRespList = new ArrayList<>();
//for (EBook eBook: eBookList) {
// //EBookResp eBookResp = new EBookResp();
// ////spring boot 自带的BeanUtils完成对象的拷贝
// //BeanUtils.copyProperties(eBook, eBookResp);
// //eBookResp.setId(12345L);
// //单体复制
// EBookResp copy = copy(eBook, EBookResp.class);
// eBookRespList.add(copy);
//}
//列表复制
List<EBookResp> respList = copyList(eBookList, EBookResp.class);
return respList;
}
}
查看接口返回数据，如下：
2.4、list列表一行显示为多条数据
接口改造完成，接着需要对列表显示内容进行修改，同样在list列表找到栅格列表，我们还在home中修改，示例代码如下：
<template>
<a-layout>
`<a-layout-sider width="200" style="background: #fff">
<a-menu
mode="inline"
v-model:selectedKeys="selectedKeys2"
v-model:openKeys="openKeys"
:style="{ height: '100%', borderRight: 0 }"
>
<a-sub-menu key="sub1">
<template #title>
<span>
<user-outlined />
subnav 1
</span>
</template>
<a-menu-item key="1">option1</a-menu-item>
<a-menu-item key="2">option2</a-menu-item>
<a-menu-item key="3">option3</a-menu-item>
<a-menu-item key="4">option4</a-menu-item>
</a-sub-menu>
<a-sub-menu key="sub2">
<template #title>
<span>
<laptop-outlined />
subnav 2
</span>
</template>
<a-menu-item key="5">option5</a-menu-item>
<a-menu-item key="6">option6</a-menu-item>
<a-menu-item key="7">option7</a-menu-item>
<a-menu-item key="8">option8</a-menu-item>
</a-sub-menu>
<a-sub-menu key="sub3">
<template #title>
<span>
<notification-outlined />
subnav 3
</span>
</template>
<a-menu-item key="9">option9</a-menu-item>
<a-menu-item key="10">option10</a-menu-item>
<a-menu-item key="11">option11</a-menu-item>
<a-menu-item key="12">option12</a-menu-item>
</a-sub-menu>
</a-menu>
</a-layout-sider>`
<a-list item-layout="vertical" size="large"
:grid="{ gutter: 16, column: 3 }" :data-source="ebooks1">
<template #renderItem="{ item }">
<a-list-item key="item.name">
<template #actions>
<span v-for="{ type, text } in actions" :key="type">
<component v-bind:is="type" style="margin-right: 8px" />
{{ text }}
</span>
</template>
<a-list-item-meta :description="item.description">
<template #title>
<a :href="item.href" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >{{ item.name }}</a>
</template>
<template #avatar><a-avatar :src="item.cover" /></template>
</a-list-item-meta>
</a-list-item>
</template>
</a-list>
</a-layout>
</template>
<script lang="ts">
import { defineComponent,onMounted,ref,reactive,toRef} from 'vue';
import axios from 'axios';
import { StarOutlined, LikeOutlined, MessageOutlined } from '@ant-design/icons-vue';
const listData: Record<string, string>[] = [];
export default defineComponent({
components: {
StarOutlined,
LikeOutlined,
MessageOutlined,
},
name: 'Home',
setup(){
const pagination = {
onChange: (page: number) => {
console.log(page);
},
pageSize: 3,
};
const actions: Record<string, string>[] = [
{ type: 'StarOutlined', text: '156' },
{ type: 'LikeOutlined', text: '156' },
{ type: 'MessageOutlined', text: '2' },
];
console.log('set up');
//使用ref进行数据绑定
const ebooks=ref();
// 使用reactive进行数据绑定
const ebooks1=reactive({books:[]})
onMounted(()=>{
axios.get("http://localhost:8888/ebook/list?name=").then(response =>{
console.log("onMounted");
const data=response.data;
ebooks.value=data.content;
ebooks1.books=data.content;
})
})
return{
pagination,
actions,
ebooks1: ebooks,
ebooks2:toRef(ebooks1,"books")
}
}
});
</script>
<style>
.ant-layout-sider{
float: left;
}
</style>
知识点：
:grid="{ gutter: 16, column: 4 }"，是进行栅格显示，栅格间隔16，每行显示4个- 这里要删除:
pagination="pagination"，即分页显示
再来重新编译，查看效果如下：
2.5、列表内容前图标样式修改
一切看是很好，但感觉是图书封面有点小不好看，如下图：
来接着改样式，只需在home里调整即可，示例代码如下：
html
<template>
<a-layout>
`<a-layout-sider width="200" style="background: #fff">
<a-menu
mode="inline"
v-model:selectedKeys="selectedKeys2"
v-model:openKeys="openKeys"
:style="{ height: '100%', borderRight: 0 }"
>
<a-sub-menu key="sub1">
<template #title>
<span>
<user-outlined />
subnav 1
</span>
</template>
<a-menu-item key="1">option1</a-menu-item>
<a-menu-item key="2">option2</a-menu-item>
<a-menu-item key="3">option3</a-menu-item>
<a-menu-item key="4">option4</a-menu-item>
</a-sub-menu>
<a-sub-menu key="sub2">

});
</script>
<style scoped>
