Today, I will talk to you about how to set up cross-domain in Springboot. Many people may not know much about it. In order to make you understand better, the editor has summarized the following for you. I hope you can get something according to this article.

Mode 1 (fine configuration)

Add @ CrossOrigin annotations to the entire Controller or a single method that needs to be cross-domain

Method 2 (global configuration) @ Configuration

Public class WebMvcConfig extends WebMvcConfigurerAdapter {

@ Override

Public void addCorsMappings (CorsRegistry registry) {

Registry.addMapping ("/ *")

.allowedOrigins ("*")

.allowedMethods ("POST", "GET", "PUT", "OPTIONS", "DELETE")

.maxAge (3600)

.allowCredentials (true)

}

}

Method 3 (through filter) @ Component

@ WebFilter (urlPatterns = "/ *", filterName = "authFilter") / / the "/ *" here indicates the request path to be intercepted

Public class PassHttpFilter implements Filter {

@ Override

Public void init (FilterConfig filterConfig) throws ServletException {}

@ Override

Public void doFilter (ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

HttpServletResponse httpResponse = (HttpServletResponse) servletResponse

HttpResponse.setHeader ("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept")

HttpResponse.setHeader ("Access-Control-Allow-Credentials", "true")

HttpResponse.addHeader ("Access-Control-Allow-Origin", "http://127.0.0.1:8080");"

FilterChain.doFilter (servletRequest, httpResponse)

}

@ Override

Public void destroy () {}

}
