方式一(精细配置)
在需要跨域的整个Controller或者单个方法上添加@CrossOrigin注解
方式二(全局配置)
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins("*")
.allowedMethods("POST", "GET", "PUT", "OPTIONS", "DELETE")
.maxAge(3600)
.allowCredentials(true);
}
}
方式三(通过filter)
@Component
@WebFilter(urlPatterns = "/*", filterName = "authFilter") //这里的“/*” 表示的是需要拦截的请求路径
public class PassHttpFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException { }
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletResponse httpResponse = (HttpServletResponse)servletResponse;
httpResponse.setHeader("Access-Control-Allow-Headers","Origin, X-Requested-With, Content-Type, Accept");
httpResponse.setHeader("Access-Control-Allow-Credentials", "true");
httpResponse.addHeader("Access-Control-Allow-Origin", "http://127.0.0.1:8080");
filterChain.doFilter(servletRequest, httpResponse);
}
@Override
public void destroy() { }
}
