如果我须要使得一个办法采取异步执行
如果我须要使得一个办法采取异步执行，并且执行的时候须要指定线程池，那么我须要做三步操作。
1、配置线程池

@Configuration@EnableAsyncpublic class ExecutorConfig implements AsyncConfigurer {    @Bean("asyncServiceExecutor")    @Override    public Executor getAsyncExecutor() {        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();        //配置外围线程数        executor.setCorePoolSize(10);        //配置最大线程数        executor.setMaxPoolSize(20);        //配置队列大小        executor.setQueueCapacity(99999);        //配置线程池中的线程的名称前缀        executor.setThreadNamePrefix("async-service-");        // rejection-policy：当pool曾经达到max size的时候，如何解决新工作        // CALLER_RUNS：不在新线程中执行工作，而是由调用者所在的线程来执行        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());        //执行初始化        executor.initialize();        return executor;    }}

2、启用异步办法注解

@EnableAsync

3、在办法上开启注解，并配置线程池

@Async("asyncServiceExecutor")

springboot系统启动时初始化数据

@Component@Slf4jpublic class ApplicationRunnerImpl implements ApplicationRunner {    @Override    public void run(ApplicationArguments args) {    }}

配置拦截器
1、增加拦截器配置文件

@Configurationpublic class MyWebConfig implements WebMvcConfigurer {    @Value("${api.contextPath}")    private String apiContextPath;    @Override    public void addResourceHandlers(ResourceHandlerRegistry registry) {    }    public String getLocalFileServerDir() {        return System.getProperty("user.dir") + "/data/";    }    @Resource    private SessionInterceptor sessionInterceptor;    @Override    public void addInterceptors(InterceptorRegistry registry) {           registry.addInterceptor(sessionInterceptor)                .addPathPatterns(apiContextPath + "/**")                .excludePathPatterns(apiContextPath + "/user/test")                .excludePathPatterns(apiContextPath + "/***")                .excludePathPatterns(apiContextPath + "/log/**");    }    @Override    public void addCorsMappings(CorsRegistry registry) {        registry.addMapping("/**")                .allowedOrigins("*")                .allowCredentials(true)                .allowedMethods("GET", "POST", "DELETE", "PUT", "PATCH")                .maxAge(3600 * 24)                .allowedHeaders("*")// 容许头部设置                .allowCredentials(true);  // 是否发送cookie    }}
