springboot+vue开发知识中心的代码

对于开发一个知识中心的应用程序，你可以使用Spring Boot作为后端框架，Vue.js作为前端框架。以下是一个简单的代码示例：

后端代码（使用Spring Boot）：

@RestController
@RequestMapping("/api")
public class KnowledgeController {

    @Autowired
    private KnowledgeService knowledgeService;

    @GetMapping("/knowledge")
    public List<Knowledge> getAllKnowledge() {
        return knowledgeService.getAllKnowledge();
    }

    @PostMapping("/knowledge")
    public Knowledge createKnowledge(@RequestBody Knowledge knowledge) {
        return knowledgeService.createKnowledge(knowledge);
    }

    @GetMapping("/knowledge/{id}")
    public Knowledge getKnowledgeById(@PathVariable Long id) {
        return knowledgeService.getKnowledgeById(id);
    }

    @PutMapping("/knowledge/{id}")
    public Knowledge updateKnowledge(@PathVariable Long id, @RequestBody Knowledge knowledge) {
        return knowledgeService.updateKnowledge(id, knowledge);
    }

    @DeleteMapping("/knowledge/{id}")
    public void deleteKnowledge(@PathVariable Long id) {
        knowledgeService.deleteKnowledge(id);
    }
}

@Service
public class KnowledgeService {

    private List<Knowledge> knowledgeList = new ArrayList<>();

    public List<Knowledge> getAllKnowledge() {
        return knowledgeList;
    }

    public Knowledge createKnowledge(Knowledge knowledge) {
        knowledge.setId((long) (knowledgeList.size() + 1));
        knowledgeList.add(knowledge);
        return knowledge;
    }

    public Knowledge getKnowledgeById(Long id) {
        return knowledgeList.stream()
                .filter(knowledge -> knowledge.getId().equals(id))
                .findFirst()
                .orElse(null);
    }

    public Knowledge updateKnowledge(Long id, Knowledge updatedKnowledge) {
        Knowledge knowledge = getKnowledgeById(id);
        if (knowledge != null) {
            knowledge.setTitle(updatedKnowledge.getTitle());
            knowledge.setContent(updatedKnowledge.getContent());
        }
        return knowledge;
    }

    public void deleteKnowledge(Long id) {
        knowledgeList.removeIf(knowledge -> knowledge.getId().equals(id));
    }
}

public class Knowledge {

    private Long id;
    private String title;
    private String content;

    // getters and setters

}

前端代码（使用Vue.js）：

<template>
  <div>
    <h1>Knowledge Center</h1>
    <form @submit.prevent="createKnowledge">
      <input v-model="newKnowledge.title" placeholder="Title" required>
      <textarea v-model="newKnowledge.content" placeholder="Content" required></textarea>
      <button type="submit">Create</button>
    </form>
    <ul>
      <li v-for="knowledge in knowledgeList" :key="knowledge.id">
        <h2>{{ knowledge.title }}</h2>
        <p>{{ knowledge.content }}</p>
        <button @click="deleteKnowledge(knowledge.id)">Delete</button>
      </li>
    </ul>
  </div>
</template>

<script>
import axios from 'axios';

export default {
  data() {
    return {
      knowledgeList: [],
      newKnowledge: {
        title: '',
        content: ''
      }
    };
  },
  mounted() {
    this.fetchKnowledgeList();
  },
  methods: {
    fetchKnowledgeList() {
      axios.get('/api/knowledge')
        .then(response => {
          this.knowledgeList = response.data;
        })
        .catch(error => {
          console.error(error);
        });
    },
    createKnowledge() {
      axios.post('/api/knowledge', this.newKnowledge)
        .then(response => {
          this.knowledgeList.push(response.data);
          this.newKnowledge.title = '';
          this.newKnowledge.content = '';
        })
        .catch(error => {
          console.error(error);
        });
    },
    deleteKnowledge(id) {
      axios.delete(`/api/knowledge/${id}`)
        .then(() => {
          this.knowledgeList = this.knowledgeList.filter(knowledge => knowledge.id !== id);
        })
        .catch(error => {
          console.error(error);
        });
    }
  }
};
</script>

这只是一个简单的示例，你可以根据自己的需求进行扩展和修改。后端使用了Spring Boot提供的@RestController和@RequestMapping注解来定义RESTful API，前端使用了Vue.js来渲染页面并与后端进行交互。同时，你需要配置好数据库连接等相关配置。

请根据你的具体需求进行适当的修改和完善。希望对你有所帮助！
