vue的axios連接springsecurity的跨域問題

我改了很多地方，至於哪個位置最關鍵我也不懂，可以都試一下

首先是後臺的配置，最爲關鍵的配置
security的配置
我就寫最主要的

@EnableWebSecurity
@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
@Order(-1)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
	@Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .cors()//我最後是加了這個纔好的
    }
}

然後是一個配置類 也很重要，配置一般的跨域問題

package com.trueway.zhdwapp.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

/**
 * @author cai
 * @version 1.0
 * @date 2020/4/8 21:06
 */
@Configuration//配置解決跨域問題
public class CorsConfig implements WebMvcConfigurer {


    private CorsConfiguration buildConfig() {
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        corsConfiguration.addAllowedOrigin("*");
        corsConfiguration.addAllowedHeader("*");
        corsConfiguration.addAllowedMethod("*");
        corsConfiguration.addExposedHeader("Authorization");
        return corsConfiguration;
    }

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", buildConfig());
        return new CorsFilter(source);
    }



    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**")
                .allowedOrigins("*")
                .allowedMethods("GET","HEAD","POST","PUT","DELETE","OPTION")
                .allowCredentials(true)
                .maxAge(3600)
                .allowedHeaders("*");
    }
}

之後是前端修改
這邊不是傳統的axios，要模擬form的傳遞，好像是security的原因吧

async initWebSocket() {
      let self = this
      let {status}= await self.$axios({
        method: 'post',
        url: 'http://192.168.7.42:8081/logins',
        data: {
          username: '4A078782E75A42FAA9591E9513E35087',
        },
        transformRequest: [
          function (data) {
            let ret = ''
            for (let it in data) {
              ret +=
                encodeURIComponent(it) +
                '=' +
                encodeURIComponent(data[it]) +
                '&'
            }
            return ret
          }
        ],
        headers:{
          'Content-Type': 'application/x-www-form-urlencoded'
        }
      })
