1. 后端Spring Boot实现

我们将使用Spring Boot作为后端框架，并使用MySQL作为数据库。

1.1 创建Article实体类

首先，在com.example.demo.entity包下创建一个名为Article.java的新类，并添加以下内容：

public class Article {
    private Integer id;
    private String title;
    private String content;
    private Integer authorId;
 
    // Getter and Setter methods
}

1.2 创建ArticleMapper接口

在

com.example.demo.mapper

ArticleMapper.java

@Mapper
public interface ArticleMapper {
    List<Article> findAll();
    Article findById(Integer id);
    void insert(Article article);
    void update(Article article);
    void delete(Integer id);
}

在

com.example.demo.service.impl

ArticleServiceImpl.java

@Service
public class ArticleServiceImpl implements ArticleService {
    @Autowired
    private ArticleMapper articleMapper;
 
    @Override
    public List<Article> findAll() {
        return articleMapper.findAll();
    }
 
    @Override
    public Article findById(Integer id) {
        return articleMapper.findById(id);
    }
 
    @Override
    public void create(Article article) {
        articleMapper.insert(article);
    }
 
    @Override
    public void update(Article article) {
        articleMapper.update(article);
    }
 
    @Override
    public void delete(Integer id) {
        articleMapper.delete(id);
    }
}

1.3创建ArticleController类

在

com.example.demo.controller

ArticleController.java

@RestController
@RequestMapping("/api/article")
public class ArticleController {
    @Autowired
    private ArticleService articleService;
 
    @GetMapping
    public List<Article> list() {
        return articleService.findAll();
    }
 
    @GetMapping("/{id}")
    public Article detail(@PathVariable Integer id) {
        return articleService.findById(id);
    }
 
    @PostMapping
    public Result create(@RequestBody Article article) {
        articleService.create(article);
        return Result.success("文章发布成功");
    }
 
    @PutMapping("/{id}")
    public Result update(@PathVariable Integer id, @RequestBody Article article) {
        article.setId(id);
        articleService.update(article);
        return Result.success("文章更新成功");
    }
 
    @DeleteMapping("/{id}")
    public Result delete(@PathVariable Integer id) {
        articleService.delete(id);
        return Result.success("文章删除成功");
    }
}

至此，我们已经完成了后端的发布、编辑、删除文章功能。

2. 前端Vue3实现

2.1 创建文章列表页面组件

在

src/views

ArticleList.vue

<template>
  <div>
    <el-table :data="articles">
      <el-table-column prop="id" label="ID" width="80"></el-table-column>
      <el-table-column prop="title" label="标题"></el-table-column>
      <el-table-column label="操作" width="180">
        <template v-slot="{ row }">
          <el-button @click="editArticle(row.id)">编辑</el-button>
          <el-button type="danger" @click="deleteArticle(row.id)">删除</el-button>
        </template>
      </el-table-column>
    </el-table>
  </div>
</template>
 
<script>
import { ref } from "vue";
import axios from "axios";
 
export default {
  setup() {
    const articles = ref([]);
 
    const fetchArticles = async () => {
      const response = await axios.get("/api/article");
      articles.value = response.data;
    };
 
    const editArticle = (id) => {
      // 跳转到编辑页面
    };
 
    const deleteArticle = async (id) => {
      await axios.delete(`/api/article/${id}`);
      fetchArticles();
    };
 
    fetchArticles();
 
    return { articles, editArticle, deleteArticle };
  },
};
</script>

2.2 创建文章发布页面组件

在

src/views

CreateArticle.vue

<template>
  <el-form ref="form" :model="form" label-width="80px">
    <el-form-item label="标题" prop="title">
      <el-input v-model="form.title"></el-input>
    </el-form-item>
    <el-form-item label="内容" prop="content">
      <el-input type="textarea" v-model="form.content"></el-input>
    </el-form-item>
    <el-form-item>
      <el-button type="primary" @click="submitForm('form')">发布文章</el-button>
    </el-form-item>
  </el-form>
</template>
 
<script>
import { reactive } from "vue";
import axios from "axios";
 
export default {
  setup() {
    const form = reactive({ title: "", content: "" });
 
    const submitForm = async () => {
      try {
        await axios.post("/api/article", form);
        alert("文章发布成功");
      } catch (error) {
        alert("文章发布失败");
      }
    };
 
    return { form, submitForm };
  },
};
</script>

2.3 创建文章编辑页面组件

在

src/views

EditArticle.vue

<template>
  <el-form ref="form" :model="form" label-width="80px">
    <el-form-item label="标题" prop="title">
      <el-input v-model="form.title"></el-input>
    </el-form-item>
    <el-form-item label="内容" prop="content">
      <el-input type="textarea" v-model="form.content"></el-input>
    </el-form-item>
    <el-form-item>
      <el-button type="primary" @click="submitForm">更新文章</el-button>
    </el-form-item>
  </el-form>
</template>
 
<script>
import { ref, reactive, onMounted } from "vue";
import axios from "axios";
 
export default {
  props: {
    id: {
      type: Number,
      required: true,
    },
  },
  setup(props) {
    const form = reactive({ title: "", content: "" });
 
    const fetchArticle = async () => {
      const response = await axios.get(`/api/article/${props.id}`);
      form.title = response.data.title;
      form.content = response.data.content;
    };
 
    const submitForm = async () => {
      try {
        await axios.put(`/api/article/${props.id}`, form);
        alert("文章更新成功");
      } catch (error) {
        alert("文章更新失败");
      }
    };
 
    onMounted(fetchArticle);
 
    return { form, submitForm };
  },
};
</script>

这段代码定义了一个名为EditArticle.vue的新组件，该组件需要一个名为id的属性。组件加载时，会调用fetchArticle函数获取文章信息并填充到表单中。点击"更新文章"按钮时，会调用submitForm函数，将表单数据发送到后端以更新文章。
