SpringBoot配置Access-Control-Allow-Origin教程
作者：白日做梦_
文章介绍了三种配置Spring Boot跨域访问的方法：1. 使用过滤器；2. 在WebConfig配置文件中设置；3. 通过注解配置,作者分享了个人经验,并鼓励读者支持脚本之家
SpringBoot配置Access-Control-Allow-Origin
1. 配置过滤器
@Component
@WebFilter(urlPatterns = "/*", filterName = "CorsFilter")
public class CorsFilter implements Filter {
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
HttpServletResponse response = (HttpServletResponse) res;
HttpServletRequest reqs = (HttpServletRequest) req;
String curOrigin = reqs.getHeader("Origin");
response.setHeader("Access-Control-Allow-Origin", curOrigin == null ? "true" : curOrigin);
response.setHeader("Access-Control-Allow-Credentials", "true");
response.setHeader("Access-Control-Allow-Methods", "POST, GET, PATCH, DELETE, PUT");
response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
chain.doFilter(req, res);
}
@Override
public void init(FilterConfig filterConfig) {
}
@Override
public void destroy() {}
}2. webconfig 配置文件
@Configuration
public class CorsConfig extends WebMvcConfigurerAdapter {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**").allowedOrigins("*")
.allowedMethods("GET", "HEAD", "POST","PUT", "DELETE", "OPTIONS")
.allowCredentials(true).maxAge(3600);
}
}@Configuration
public class XXXXMvcConfigurer implements WebMvcConfigurer {
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins("*")
.allowCredentials(true)
.allowedMethods("GET", "POST", "DELETE", "PUT","PATCH")
.maxAge(3600);
}
}3. 结果查验
总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
