Spring Boot实现跨域访问实现代码

Spring Boot实现跨域访问实现代码

当前使用spring版本是4.3.9

import org.springframework.stereotype.Component;

import javax.servlet.*;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

@Component

public class CorsFilter implements Filter {

@Overhttp://ride

public void init(FilterConfig filterConfig) throws ServletException {

}

@Override

public void doFilter(ServletRequest servletRequest,

ServletResponse servletResponse,

FilterChain filterChain) throws IOException, ServletException {

HttpServletRequest request = (HttpServletRequest) servletRequest;

HttpServletResponse response = (HttpServletResponse) servletResponse;

response.setHeader("Access-Control-Allow-Origin", request.getHeader("origin"));

// response.setHeader("Access-Control-Allow-Origin", "*");//允许跨域访问的域

response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");//允许使用的请求方法，以逗号隔开

response.setHeader("Access-Control-Max-Age", "3600");// 缓存此次请求的秒数

//允许使用的请求方法，以逗号隔开

response.setHeader("Access-Control-Allow-Headers", "x-requested-with,Cache-Control,Pragma,Content-Type,Token");

response.setHeader("Access-Control-Allow-Credentials","true");//是否允许请求带有验证信息

filterChain.doFilter(servletRequest, servletResponse);

}

@Override

public void destroy() {

}

}

PS： spring boot 服务器端设置允许跨域访问

import org.springframework.stereotype.Component;

import javax.servlet.*;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

/**

*

* 跨域过滤器

* @author meng

* @version

* @since 2016年6月19日

*/

@Component

public class CorsFilter implements Filter {

final static org.slf4j.Logger logger = org.slf4j.LoggerFactory.getLogger(CorsFilter.class);

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", "x-requested-with");

System.out.println("*********************************过滤器被使用**************************");

chain.doFilter(req, res);

}

public void init(FilterConfig filterConfig) {}

public void destroy() {}

}

2017-04-13更新：

第二种方法，在Appplication.java添加：

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()); // 4

return new CorsFilter(source);

}
