Unusual $http Angular.js POST inquiry

Hey there, I'm facing a peculiar issue in my web development project. I have a table that acts as an input field where users can enter data and then send it back to the Spring Rest API. The data is received as a String and then parsed using the Gson library.

$http({
    method: 'POST',
    url: 'saveTableData.do',
    headers: { 'Content-Type': 'application/json;'},
    data:'tableVal'+data1
}) ;

Here is a snippet of my Spring controller:

@RequestMapping(value="/saveTableData",method=RequestMethod.POST)
public void saveTableDataToDb(@RequestBody String tableData) {

    Gson gson = new Gson();
    TableData dataFromJson = gson.fromJson(tableData, TableData.class);
}

Although the data is being sent successfully to the backend, I am seeing the following error message in the console: Failed to load resource: the server responded with a status of 404 (Not Found)

I am wondering why this error is occurring and if it will have any impact on the project in the future.

Answer №1

I don't have much experience with Spring, but I believe the reason for the 404 error might be because your method is not returning anything.

In a simplified example, it should look something like this:

public Response saveDataToDatabase(MyObject myObject) {
    // Implement some business logic here
    Response response = new Response();
    response.setStatusCode(200); // HTTP status code for success
    return response;
}

Since you currently have a void method, my guess is that this could be causing the issue. Hope this helps!
