1、SpringMVC 4.2以上版本。
2、添加sping配置：
<mvc:cors>
<mvc:mapping path="/**" />
</mvc:cors>
3、添加过滤器CORSFilter：
@Component
public class CORSFilter implements Filter{
public void destroy() {}
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", "Origin, X-Requested-With, Content-Type, Accept");
chain.doFilter(req, res);
}
public void init(FilterConfig arg0) throws ServletException {}
}
4、web.xml中添加配置
<filter>
<filter-name>cors</filter-name>
<filter-class>com.account.admin.filter.CORSFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>cors</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
