package com.wzq.test.action;
import com.wzq.utils.BatchDownFilesUtils;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.*;
import java.nio.file.Files;
import java.util.ArrayList;
import java.util.List;
/**
 * @description: 测试Controller
 * @author: Wzq
 * @create: 2019-11-25 10:19
 */
@CrossOrigin(origins = "*")
@RestController
@RequestMapping(value = "test")
public class TestController{
@RequestMapping(value = "/test.do")
    public String test(){
        return "test";
}
}

这种方式对于整个项目都要跨域，那么每个类上都要加@CrossOrigin元注解,比较麻烦，下面讲解下全局跨域配置。

第二种拦截器的方式

packagecom.wzq;
importorg.springframework.boot.SpringApplication;
importorg.springframework.boot.autoconfigure.SpringBootApplication;
importorg.springframework.boot.web.servlet.FilterRegistrationBean;
importorg.springframework.context.annotation.Bean;
importorg.springframework.web.cors.CorsConfiguration;
importorg.springframework.web.cors.UrlBasedCorsConfigurationSource;
importorg.springframework.web.filter.CorsFilter;
@SpringBootApplication
publicclassMyprojectApplication{
publicstaticvoidmain(String[] args){
SpringApplication.run(MyprojectApplication.class, args);
}
@Bean
publicFilterRegistrationBeancorsFilter(){
UrlBasedCorsConfigurationSource source =newUrlBasedCorsConfigurationSource();
CorsConfiguration config =newCorsConfiguration();
        config.setAllowCredentials(true);
        config.addAllowedOrigin("*");
        config.addAllowedHeader("*");
        config.addAllowedMethod("*");
        source.registerCorsConfiguration("/**", config);// CORS 配置对所有接口都有效
FilterRegistrationBean bean =newFilterRegistrationBean(newCorsFilter(source));
        bean.setOrder(0);
return bean;
}
}

第三种集成WebMvcConfigurerAdapter类重写 addCorsMappings方法

package com.meeno.wzq;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
/**
 * @Auther: Wzq
 * @Date: 2019/4/11 18:30
 * @Description: 天青色等烟雨，而我在等你.. -- CORSConfiguration
 */
@Configuration
public class CORSConfiguration  extends WebMvcConfigurerAdapter{
@Override
    public void addCorsMappings(CorsRegistry registry){
        registry.addMapping("/**")
                .allowedMethods("*")
                .allowedOrigins("*")
                .allowedHeaders("*");
        super.addCorsMappings(registry);
}
}

第三种有个问题，session无法共享!

第四种使用nginx代理把前端项目和服务端api接口地址,保持在同一个ip和端口中

完整的nginx配置如下:


#user  nobody;
worker_processes  1;
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
#pid        logs/nginx.pid;
events {
    worker_connections  1024;
}
http {
include       mime.types;
    default_type  application/octet-stream;
#log_format  main  "$remote_addr - $remote_user [$time_local] "$request" "
#                  "$status $body_bytes_sent "$http_referer" "
#                  ""$http_user_agent" "$http_x_forwarded_for"";
#access_log  logs/access.log  main;
    sendfile        on;
#tcp_nopush     on;
#keepalive_timeout  0;
    keepalive_timeout  65;
#gzip  on;
    server {
        listen       20684;
        server_name  inner.meeno.net;
#charset koi8-r;
#access_log  logs/host.access.log  main;
        location /trainsys {
#root   html;
#index  index.html index.htm;
            client_max_body_size 100000m;
            proxy_set_header Host $host;
            proxy_set_header X-Real-Ip $remote_addr;
            proxy_set_header X-Forwarded-For$remote_addr;
            proxy_pass http://inner.meeno.net:20681/trainsys/;
}
        location /dist {
            root   E:svnResourseprogramwebTwosysBankAdmin-Vue;
            index  index.html index.htm;
}
#error_page  404              /404.html;
# redirect server error pages to the static page /50x.html
#
        error_page   500502503504/50x.html;
        location =/50x.html {
            root   html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ .php$ {
#    proxy_pass   http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ .php$ {
#    root           html;
#    fastcgi_pass   127.0.0.1:9000;
#    fastcgi_index  index.php;
#    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
#    include        fastcgi_params;
#}
# deny access to .htaccess files, if Apache"s document root
# concurs with nginx"s one
#
#location ~ /.ht {
#    deny  all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
#    listen       8000;
#    listen       somename:8080;
#    server_name  somename  alias  another.alias;
#    location / {
#        root   html;
#        index  index.html index.htm;
#    }
#}
# HTTPS server
#
#server {
#    listen       443 ssl;
#    server_name  localhost;
#    ssl_certificate      cert.pem;
#    ssl_certificate_key  cert.key;
#    ssl_session_cache    shared:SSL:1m;
#    ssl_session_timeout  5m;
#    ssl_ciphers  HIGH:!aNULL:!MD5;
#    ssl_prefer_server_ciphers  on;
#    location / {
#        root   html;
#        index  index.html index.htm;
#    }
#}
}

主要看这段:


listen       8080;#端口
server_name  127.0.0.1;#ip或域名
#服务端api基地值
 location /trainsys {
#root   html;
#index  index.html index.htm;
            client_max_body_size 100000m;
            proxy_set_header Host $host;
            proxy_set_header X-Real-Ip $remote_addr;
            proxy_set_header X-Forwarded-For$remote_addr;
            proxy_pass http://inner.meeno.net:20681/trainsys/;
}
#web端项目映射地址
        location /dist {
            root   E:svnResourseprogramwebTwosysBankAdmin-Vue;
            index  index.html index.htm;
}
