springboot vue 每次请求jsessionid都不一样的问题

1、前端：axios增加属性withCredentials:true

const service = axios.create({
    baseUrl: 'http://xxxxxxxx',
    withCredentials: true,
    timeout: 60000
})

2、后端1：修改配置文件，设置addAllowedOriginPattern，addAllowedHeader，setAllowCredentials属性

@Configuration
public class VeWebMvcConfigurer implements WebMvcConfigurer {
    @Bean
    public CorsFilter corsFilter() {
        CorsConfiguration config = new CorsConfiguration();
        config.addAllowedMethod(HttpMethod.GET);
        config.addAllowedMethod(HttpMethod.POST);
        config.addAllowedMethod(HttpMethod.DELETE);
        config.addAllowedMethod(HttpMethod.PUT);
        config.addAllowedMethod(HttpMethod.OPTIONS);
        config.addAllowedOriginPattern("*");
        config.addAllowedHeader("*");
        config.setAllowCredentials(true);
        UrlBasedCorsConfigurationSource corsConfigurationSource = new UrlBasedCorsConfigurationSource();
        corsConfigurationSource.registerCorsConfiguration("/**", config);
        return new CorsFilter(corsConfigurationSource);
    }
}

3、后端2：在继承了WebSecurityConfigurerAdapter的类中的configure方法里设置属性sessionManagement().sessionFixation().changeSessionId().disable()

重启前后端项目看看jsessionid是不是固定了
