JavaWeb第四次课后作业

1，使用原始不分层的方法

一， writer.html文件：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>诗人信息列表展示</title>
</head>

<link rel="stylesheet" href="element-ui/index.css">
<script src="./js/vue.js"></script>
<script src="./element-ui/index.js"></script>
<script src="./js/axios-0.18.0.js"></script>

<body>
<h1 align="center">诗人信息列表展示</h1>
<div id="app">
    <el-table :data="rawTableData" style="width: 100%"  stripe border >
        <el-table-column prop="number" label="序号" align="center" min-width="20%"></el-table-column>
        <el-table-column prop="name" label="姓名" align="center" min-width="20%"></el-table-column>
        <el-table-column prop="gender" label="性别" align="center"  min-width="20%"></el-table-column>
        <el-table-column prop="dynasty" label="朝代 " align="center"  min-width="20%"></el-table-column>
        <el-table-column prop="rank" label="头衔 " align="center"  min-width="20%"></el-table-column>
        <el-table-column prop="mode" label="风格 " align="center"  min-width="20%"></el-table-column>
    </el-table>
</div>
</body>

<style>
    .el-table .warning-row {
        background: oldlace;
    }
    .el-table .success-row {
        background: #f0f9eb;
    }
</style>

<script>
    new Vue({
        el: "#app",
        data() {
            return {
                rawTableData: []
            }
        },
        mounted(){
            axios.get('/listWriter').then(res=>{
                if(res.data.code){
                    this.rawTableData = res.data.data;
                }
            });
        },
        methods: {
        }
    });
</script>
</html>

二：writerController文件：

package com.wust.controller;


import com.wust.pojo.Result;
import com.wust.pojo.Writer;
import com.wust.utils.XmlParserUtils1;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;
@RestController
public class WriterController {
    @RequestMapping("/listWriter")
    public Result list(){
        //1.加载并解析writer.xml
//
        String file=this.getClass().getClassLoader().getResource("writer.xml").getFile();
        System.out.println(file);
        List<Writer> writerList= XmlParserUtils1.parse(file, Writer.class);
        //2.对数据进行转化处理gender--运用stream流
        writerList.stream().forEach(writer -> {
            //处理gender 1：男 2： 女
            String gender=writer.getGender();
            if("1".equals(gender)){
                writer.setGender("男");
            }else if ("2".equals(gender)){
                writer.setGender("女");
            }

        });
        //3.响应结果
        return Result.success(writerList);


    }
}

三，writer.java文件

package com.wust.pojo;

public class Writer {
    private String name;
    private Integer number;
    private String dynasty;
    private String gender;
    private String rank;
    private String mode;

    public Writer(String name, Integer number, String dynasty, String gender, String rank, String mode) {
        this.name = name;
        this.number = number;
        this.dynasty = dynasty;
        this.gender = gender;
        this.rank = rank;
        this.mode = mode;
    }

    public String getName() {
        return name;
    }

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

    public Integer getNumber() {
        return number;
    }

    public void setNumber(Integer number) {
        this.number = number;
    }

    public String getDynasty() {
        return dynasty;
    }

    public void setDynasty(String dynasty) {
        this.dynasty = dynasty;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public String getRank() {
        return rank;
    }

    public void setRank(String rank) {
        this.rank = rank;
    }

    public String getMode() {
        return mode;
    }

    public void setMode(String mode) {
        this.mode = mode;
    }

    @Override
    public String toString() {
        return "writer{" +
                "name='" + name + '\'' +
                ", number=" + number +
                ", dynasty='" + dynasty + '\'' +
                ", gender='" + gender + '\'' +
                ", rank='" + rank + '\'' +
                ", mode='" + mode + '\'' +
                '}';
    }
}

2.三层架构

1.当我们在前端发起请求后，请求先到达Controller程序——负责接受请求，响应数据

2.在接受请求后Controller程序去调用service层中的方法 ——负责具体的逻辑处理

3.获取数据，service层，去调用Bao程序——负责数据的访问操作

4.bao查询的数据返回给service进行逻辑处理，后再将处理后的数据返回Controller程序

WrriterController代码：

package com.wust.controller;


import com.wust.pojo.Result;
import com.wust.pojo.Writer;
import com.wust.service.WriterSerive;
import com.wust.service.impl.WriterSeriveA;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;
@RestController
public class WriterController {
    private WriterSerive writerSerive=new WriterSeriveA();
    @RequestMapping("/listWriter")
    public Result list(){
        List<Writer> writerList = writerSerive.listWriter();
        return Result.success(writerList);
    }

}

WriterDaoA代码：

package com.wust.dao.impl;

import com.wust.dao.WriterDao;
import com.wust.pojo.Writer;
import com.wust.utils.XmlParserUtils1;

import java.util.List;

public class WriterDaoA implements WriterDao {
    @Override
    public List<Writer> Writerlist() {
        String file=this.getClass().getClassLoader().getResource("writer.xml").getFile();
        System.out.println(file);
        List<Writer> writerList= XmlParserUtils1.parse(file, Writer.class);
        return writerList;
    }
}

WriterSeriveA代码：

package com.wust.service.impl;

import com.wust.dao.WriterDao;
import com.wust.dao.impl.WriterDaoA;
import com.wust.pojo.Result;
import com.wust.pojo.Writer;
import com.wust.service.WriterSerive;

import java.util.List;

public class WriterSeriveA implements WriterSerive {
    private WriterDao writerDao=new WriterDaoA();
    @Override
    public List<Writer> listWriter() {
        List<Writer> writerList = writerDao.Writerlist();
        writerList.stream().forEach(writer -> {
            //处理gender 1：男 2： 女
            String gender=writer.getGender();
            if("1".equals(gender)){
                writer.setGender("男");
            }else if ("2".equals(gender)){
                writer.setGender("女");
            }

        });
        //3.响应结果
        return writerList;

    }
}
