配置线程池/任务执行器

**SpringBoot默认单线程执行，需要多线程异步执行，需要@EnableAsync并设置ThreadPoolTaskExecutor，仅仅开启@EnableAsync 1.4.X版本仍是单线程执行，1.5.X会报错提醒设置线程池！**

//可以设置执行任务的线程池的数量。默认是单线程。
    @Bean
    public ThreadPoolTaskScheduler getDefaultThreadPoolScheduler(){
        ThreadPoolTaskScheduler threadPoolTaskScheduler = new ThreadPoolTaskScheduler();
        threadPoolTaskScheduler.setPoolSize(2);
        threadPoolTaskScheduler.setThreadNamePrefix("scheduleMoon");
        return threadPoolTaskScheduler;
    }

//spingBoot默认单线程执行
    @Bean
    public ThreadPoolTaskExecutor createThreadPoolTaskExecutor() {
         ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor();
         threadPoolTaskExecutor.setCorePoolSize(10);
         threadPoolTaskExecutor.setMaxPoolSize(20);
         return threadPoolTaskExecutor;
    }

配置跨域

private CorsConfiguration buildConfig() {  
            CorsConfiguration corsConfiguration = new CorsConfiguration();  
            corsConfiguration.addAllowedOrigin("*");  
            corsConfiguration.addAllowedHeader("*");  
            corsConfiguration.addAllowedMethod("*");  
            return corsConfiguration;  
        }  
    
        /** 
         * 跨域过滤器 
         * @return 
         */  
        @Bean  
        public CorsFilter corsFilter() {  
            UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();  
            source.registerCorsConfiguration("/**", buildConfig()); // 4  
            return new CorsFilter(source);  
        }

配置文件上传

@Bean 
        public MultipartConfigElement multipartConfigElement() { 
            MultipartConfigFactory factory = new MultipartConfigFactory();
             设置文件大小限制 ,超了，页面会抛出异常信息，这时候就需要进行异常信息的处理了;
            factory.setMaxFileSize("400MB"); //KB,MB
            /// 设置总上传数据总大小
            factory.setMaxRequestSize("400MB"); 
            //Sets the directory location where files will be stored.
            //factory.setLocation("路径地址");
            return factory.createMultipartConfig(); 
        }

配置全局拦截器

@Override
        public void addInterceptors(InterceptorRegistry registry) {
            // addPathPatterns 用于添加拦截规则
            // excludePathPatterns 用户排除拦截
            registry.addInterceptor(new GlobalInterceptor()).addPathPatterns("/**").excludePathPatterns("/common/**");
    
    //      registry.addInterceptor(new MyInterceptor2()).addPathPatterns("/**");
            super.addInterceptors(registry);
        }

监听器

spring application context：

public class ApplicationStartUpListener implements ApplicationListener<ApplicationStartingEvent>{
    
        @Override
        public void onApplicationEvent(ApplicationStartingEvent event) {
            PropertyUtil.loadAllProperties();
            System.out.println(">>>>>>>>>>>>>>>>>>>>>>ApplicationStartUpListener EXEC");
        }
    }

servlet context：

@WebListener
    public class MyServletContextListener implements ServletContextListener {
    
        @Override
        public void contextInitialized(ServletContextEvent sce) {
            System.out.println("ServletContex初始化");
            System.out.println(sce.getServletContext().getServerInfo());
        }
    
        @Override
        public void contextDestroyed(ServletContextEvent sce) {
            System.out.println("ServletContex销毁");
        }
    
    }

## 请求aop日志切割    ##

@Aspect
    @Component
    public class LogOrderAspect {
        private static final Logger logger = LoggerFactory.getLogger(LogOrderAspect.class);
        @Resource private LogOrderOperationService logOrderService;
    
        @Before("@annotation(orderAspect)")
        public void gennerateLog(JoinPoint point, LogOrderAnnotation orderAspect) throws Throwable {
            logger.info(">>>>>>订单操作开始aspect");
            ServletContextUtil context = ServletContextUtil.getContext();
            HttpServletRequest request = context.getRequest();
    
            LogOrderOperation log = new LogOrderOperation();
            log.setAction(orderAspect.action());
            log.setUserId(LongUtils.parseLong(request.getParameter("userId")));
            Map<String, String[]> params = Maps.newHashMap(request.getParameterMap());
            params.put("url", new String[]{request.getRequestURI()});
            log.setParams(JSON.toJSONString(params));
            log.setCreated(new Date());
    
            logOrderService.insertEntry(log);
        }
    
        @After("@annotation(orderAspect)")
        public void endLog(JoinPoint point, LogOrderAnnotation orderAspect) {
            logger.info(">>>>>>订单操作执行完aspect");
        }
    
        @AfterReturning("@annotation(orderAspect)")
        public void returnLog(JoinPoint point, LogOrderAnnotation orderAspect) {
            logger.info(">>>>>>订单操作执行完aspect，return.................");
        }
    
    
    }
