Spring-boot中完美实现Post,Get方式的跨域请求

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
