配置 http 请求 spring mvc 和 angular js？

Question

我在本地机器上发布了这个服务：

http://joediego.dtdns.net:3000/jcsistemas/rest/cliente/all

如果我点击提到的 URL 端点，我可以通过我的 JSON 提要获得响应。但是当我使用另一个主机名时，例如 http://localhost:8081，服务会响应以下消息：

XMLHttpRequest can not load http: // localhost: 8081 / jcsistemas / rest / customer / all. In the 'Access-Control-Allow-Origin "header is present on the requested resource. Origin 'http: // localhost: 9000' is not allowed Therefore access.

以下是我迄今为止为克服同源政策问题所做的努力：

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletResponse;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;
//filter 
@Component
public class SimpleCORSFilter implements Filter {
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "x-requested-with");
        chain.doFilter(req, res);
    }

    public void init(FilterConfig filterConfig) {}
    public void destroy() {}
}

@Configuration
@EnableWebMvc
@ComponentScan("my..package...... ")
public class WebAppConfig extends WebMvcConfigurerAdapter {

    //configureContentNegotiation
    @Override
    public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
        configurer.favorPathExtension(true).
              ignoreAcceptHeader(true).
              useJaf(false).
              defaultContentType(MediaType.APPLICATION_JSON).
              mediaType("html", MediaType.TEXT_HTML).
              mediaType("xml", MediaType.APPLICATION_XML);
    }
}

AngularJS 模块配置：

angular.module('my_module').config(['$routeProvider','$httpProvider',function($routeProvider,$httpProvider) {
    //how configure headers here??    
    }]);
}());

我设法通过删除 @Component SimpleCorsFilter 并在 WebApplicationInitializer 子类中添加 getServletFilters() 方法来解决我的问题。对于那些使用基于 Java 的应用程序配置的人来说，这里是组件声明：

public MyWebApplicationInitializer implements WebApplicationInitializer 
{
    @ Override
    protected Filter[] getServletFilters() 
    {
        return new Filter[] {new MyFilter()}; // MyFilter refers to the filter needed class
    }
}
