react+spring boot development setup

Question

I am trying to setup react and spring boot in development mode.I have running front end and back end separate ports i.e; http://localhost:3000/api/hello and http://localhost:8080/api/hello respectively. I like to call services in the backend and display the results in the frontend, for that i have add "proxy": "http://localhost:8080" in react app package.json file. But its not working.

Plz help me how to fix?

package.json file

{
  "name": "frontend",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.3.1",
    "react-dom": "^16.3.1",
    "react-scripts": "1.1.4"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  },
  "proxy": "http://localhost:8080",
}

I am enable to display back end spring boot code with front end reactjs code

You don't have to define proxy port. Simply run your spring boot project and then send request from react application

For example in React:

        fetch("http://localhost:portNumber/login", {
        method: 'POST',
        headers: {'content-type': 'application/json'},
        body: JSON.stringify({
        email: this.state.emailAddress,
        password: this.state.password})
})
        .then(resopnse => {
    if(response.status === 200){
    }
        })

Spring boot:

@CrossOrigin("*")
@PostMapping("/login")
public userLogin(@RequestedBody modalName objectname){
//Service Call
}
