1.这个方法不太妥当，不够安全，需要自己去写一个拦截器

web.xml配置指向拦截器

JsonFormat

com.qianmo.qmyj.common.JsonFilter

JsonFormat

*.do

packagecom.qianmo.qmyj.common;importorg.slf4j.Logger;importorg.slf4j.LoggerFactory;importorg.springframework.stereotype.Component;import javax.servlet.*;importjavax.servlet.http.HttpServletRequest;importjavax.servlet.http.HttpServletResponse;importjava.io.IOException;/*** FileName: ${NAME}

* Description:

* History:*/@Componentpublic class JsonFilter implementsFilter {private Logger logger =LoggerFactory.getLogger(getClass());public voiddestroy() {

}public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throwsServletException, IOException {

HttpServletRequest request=(HttpServletRequest) req;

HttpServletResponse response=(HttpServletResponse) resp;

logger.debug("------->受理HTTP请求，方式为:" + ((HttpServletRequest) req).getMethod() + "

request.setCharacterEncoding("UTF-8");

response.setCharacterEncoding("UTF-8");

response.setContentType("text/json");

response.setHeader("Access-Control-Allow-Origin", "*");

response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE, PUT,HEAD");

response.setHeader("Access-Control-Max-Age", "3600");

response.setHeader("Access-Control-Allow-Headers","X-Requested-With,Content-Type");

response.setHeader("Access-Control-Allow-Credentials", "true");//response.addHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");//String curOrigin = request.getHeader("Origin");//if (curOrigin != null) {//for (int i = 0; i < originProperties.length; i++) {//logger.debug("-------->允许跨域访问的来源是：" + originProperties[i] + "

chain.doFilter(req, resp);

}public void init(FilterConfig config) throwsServletException {

}

2.还有一个办法，我在eclipse里使用，是没有问题的，不过不知道为什么在idea里总是报错，因为时间关系，我也没深究，选择了上面的解决方法，也贴在下面吧。

----------------------web.xml-------------------------------------------------

CORS

com.thetransactioncompany.cors.CORSFilter

CORS

------------------------util工具类(CorsConfig)----------------------------------------

packagecom.commerce.utils;//允许ajax跨域请求

importorg.springframework.context.annotation.Bean;importorg.springframework.context.annotation.Configuration;importorg.springframework.web.cors.CorsConfiguration;importorg.springframework.web.cors.UrlBasedCorsConfigurationSource;importorg.springframework.web.filter.CorsFilter;

@Configurationpublic classCorsConfig {privateCorsConfiguration buildConfig() {

CorsConfiguration corsConfiguration= newCorsConfiguration();

corsConfiguration.addAllowedOrigin("*"); //1

corsConfiguration.addAllowedHeader("*"); //2

corsConfiguration.addAllowedMethod("*"); //3

returncorsConfiguration;

}

@BeanpublicCorsFilter corsFilter() {

UrlBasedCorsConfigurationSource source= newUrlBasedCorsConfigurationSource();

source.registerCorsConfiguration("/**", buildConfig()); //4

return newCorsFilter(source);

}
