[FIXED] Angular/Spring MVC: how to fix the error "Required request body is missing"

Issue

I'm having a problem deleting a product from the db in the frontend (angular). I'm having this error:

Required request body is missing: public boolean prodcust.controller.DeleteController.deleteProduct(java.lang.String,prodcust.model.Product)]

I tested the Delete API in Postman and it works fine, the problem I'm only having in Angular when I click the Delete button.

CONTROLLER:

@RequestMapping(value = "/delete-product/{codeproduct}",method = RequestMethod.DELETE, produces = MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public boolean deleteProduct(@PathVariable("codeproduct") String codeproduct, @RequestBody Product product) {
    product.setCodeproduct(codeproduct);
    return productDao.deleteProduct(product);
}

DAO:

public boolean deleteProduct(Product product) {
    boolean status=false;
    try {
        jdbcTemplate.update("delete from buys where codeproduct=?", product.getCodeproduct());
        status=true;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return status;
}

Angular: service.ts

return this.http.delete(`${this.baseUrl}/delete-product/${codeproduct}`, { responseType: 'text' }); 

Solution

You have @RequestBody Product product try to send some json object or empty json {} from angular.

Use as below.

http.request('delete',. , `${this.baseUrl}/delete-product/${codeproduct}`, body: { } });
