vue.js 如何调用java

import { createApp } from 'vue'
import axios from 'axios'

const app = createApp({...})

app.config.globalProperties.$axios = axios.create({
  baseURL: 'http://localhost:8080' // Java 服务器端 URL
})

// 引入组件
import { ref } from 'vue'

export default {
  setup() {
    const response = ref({})

    // 发送 GET 请求
    $axios.get('/users')
      .then(res => { response.value = res.data })
      .catch(err => { console.log(err) })

    return { response }
  }
}

.then(res => {
  // 对数据进行操作...
})

.catch(err => {
  // 处理错误...
})

<template>
  <div>
    <ul>
      <li v-for="user in response.data">
        {{ user.name }}
      </li>
    </ul>
  </div>
</template>

<script>
import { ref } from 'vue'
import { createApp } from 'vue'
import axios from 'axios'

const app = createApp({
  data() {
    return {
      response: ref({})
    }
  },
  created() {
    axios.create({
      baseURL: 'http://localhost:8080' // Java 服务器端 URL
    }).get('/users')
      .then(res => { this.response.value = res.data })
      .catch(err => { console.log(err) })
  }
})

app.mount('#app')
</script>
