由于在javascript页面中请求数据涉及到跨域请求，困扰很久才处理完成，所以记录下来这次操作经验
1.在spring-boot中设置过滤器 ，直接上代码
@Component
public class CorsFilter implements Filter {
final static org.slf4j.Logger logger = org.slf4j.LoggerFactory
.getLogger(CorsFilter.class);
public CorsFilter(UrlBasedCorsConfigurationSource source) {
}
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, PUT");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "x-requested-with,Origin,Content-Type, Accept");
chain.doFilter(req, res);
}
public void init(FilterConfig filterConfig) {
}
public void destroy() {
}
}
2.在Application中配置全局过滤器
/**
* 跨域配置
* @return
*/
private CorsConfiguration buildConfig() {
CorsConfiguration corsConfiguration = new CorsConfiguration();
corsConfiguration.addAllowedOrigin("*");
corsConfiguration.addAllowedHeader("*");
corsConfiguration.addAllowedMethod("*");
return corsConfiguration;
}
/**
* 跨域过滤器
* @return
*/
@Bean
public CorsFilter corsFilter() {
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", buildConfig());
return new CorsFilter(source);
}
至此完美解决Post的对象请求还有正常的GET方式请求数据，经实践可正常使用
