access-control-allow-origin spring boot multi-module project

This project is combined with Java Spring boot and angular. It was a multimodule project and client site developed with angular 16. I faced this issue when I got the data district list from API.  and I solved that  Just add this class. 

package com.ayat.hrm.hrmapi.config;

import org.springframework.core.Ordered;
import org.springframework.core.annotation.Order;
import org.springframework.http.HttpMethod;
import org.springframework.stereotype.Component;

import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CorsFilter implements Filter {

@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
final HttpServletResponse response = (HttpServletResponse) res;
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Allow-Headers", "Authorization, Content-Type");
response.setHeader("Access-Control-Max-Age", "3600");
if (HttpMethod.OPTIONS.name().equalsIgnoreCase(((HttpServletRequest) req).getMethod())) {
response.setStatus(HttpServletResponse.SC_OK);
} else {
chain.doFilter(req, res);
}
}

@Override
public void destroy() {
}

@Override
public void init(FilterConfig config) throws ServletException {
}
}
