The development of the back-end interface has been completed. The
back-end interface and front-end access have been improved. The
code has been updated https://github.com/dmhsq/edusys
github code is not yet available Fully commented (sleepy) The
current effect is as follows
Improve the back-end and connect to the front-end
Perfect backend
New modifications and new interfaces
@PostMapping("/admin/change")
public RespBean change(@RequestParam("type") Integer type,
@RequestBody Object object){
return reviseService.change(type,object);
}
@PostMapping("/admin/add")
public RespBean add(@RequestParam("type") Integer type,
@RequestBody Object object){
return addService.add(type,object);
}
Modify service
Description
Determine the type according to the type and then convert the
conversion statement as follows
ObjectMapper objectMapper =new ObjectMapper();
Student student = objectMapper.convertValue(object,Student.class);
Optional<Student> studentOptional = studentRepository.findById(student.getUserId());
Code
The addition and modification are similar but the following statements are deleted
Optional<Student> studentOptional = studentRepository.findById(student.getUserId());
if (!studentOptional.isPresent()){
return RespBean.error("失败","不存在学生信息");
}
Modify the overall code block of the service as follows

Front-end access
Configure proxy
Add the following code (will be modified after the current test)
devServer:{
proxy:{
"/api": {
target: "http://localhost:8086/edusys/admin",
changeOrigin: true,
pathRewrite: {
"^/api": ""
}
},
"/login": {
target:
"http://localhost:8086/edusys/oauth/token?grant_type=password&client_id=password&client_secret=123&scope=all",
changeOrigin: true,
pathRewrite: {
"^/login": ""
}
}
}
}
Configure interface access
Configure axios
Unified package has not been tested only three external interfaces Interface landed
in 
carrying access_token before each send
import axioes from "axios";
const axios = axioes.create({
timeout: 3000,
headers: {
"Content-Type": "multipart/form-data"
}
});
const login = (username, password) => {
return axioes.post(`/login&username=${
username}&password=${
password}`);
};
//配置请求拦截器 在发送前携带access_token
axios.interceptors.request.use(
config => {
let token = localStorage.getItem("access_token");
if (token) {
config.headers.authorization = "bearer" + token;
}
return config;
},
error => {
return Promise.reject(error);
}
);
export {
login, axios };
Configuration request method
import {
login, axios } from "./axiosFun";
//查询信息
export const find = params => {
return axios.get("/api/find", {
params: params });
};
//修改信息
export const change = (type, data) => {
return axios.post(`/api/change?type=${
type}`, JSON.stringify(data),{
headers:{
"Content-Type": "application/json"}});
};
//新增
export const add = (type, data) => {
return axios.post(`/api/add?type=${
type}`, JSON.stringify(data),{
headers:{
"Content-Type": "application/json"}});
};
//登陆
export const doLogin = (username, password) => {
return login(username, password);

Access
Description
The paging function is used here. The
code will be commented when placing the warehouse.
Access new
The content of the form is as follows
The front-end code will be placed on github after the basic function development is completed
Hello, everyone, I am a code husky, a student of network engineering in the Software College, because I am a "dog", and I can eat meat for thousands of miles. I want to share what I learned during university and make progress with everyone. However, due to the limited level, there will inevitably be some mistakes in the blog. If there are any omissions, please let me know! For the time being, only update on the csdn platform, the blog homepage: https://blog.csdn.net/qq_42027681 .

Will be launched later
Front-end: vue entry vue development applet, etc.
Back-end: java entry springboot entry, etc.
Server: MySQL entry server simple instructions cloud server to run the project
python: recommended not to warm up, be sure to see
the use of some plug-ins, etc.
The way of university is also in oneself, study hard, youth
