3、jdbc.properties

4、解决跨域问题
CorsMapping
package com.zking.spboot.util;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
public class CorsMapping implements WebMvcConfigurer {
/*@Override
*
* 重新跨域支持方法
* CorsRegistry 开启跨域注册
*/
public void addCorsMappings(CorsRegistry registry) {
//addMapping 添加可跨域的请求地址
registry.addMapping("/**")
//设置跨域 域名权限 规定由某一个指定的域名+端口能访问跨域项目
.allowedOrigins("*")
//是否开启cookie跨域
.allowCredentials(false)
//规定能够跨域访问的方法类型
.allowedMethods("GET","POST","DELETE","PUT","OPTIONS")
//添加验证头信息 token
//.allowedHeaders()
//预检请求存活时间 在此期间不再次发送预检请求
.maxAge(3600);
}
}

1、BookList.vue
<template>
<div>

2、action.js
/**
* 对后台请求的地址的封装，URL格式如下：
* 模块名_实体名_操作
*/
export default {
//服务器
'SERVER': 'http://localhost:8080/spboot',
'ALL':'/book/query',
'ADD':'/book/add',
//获得请求的完整地址，用于mockjs测试时使用
'getFullPath': k => {
return this.SERVER + this[k];
}
}
3、index.js
import Vue from 'vue'
import Router from 'vue-router'
import BookList from '@/views/BookList'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'BookList',
component: BookList
}
]
})
