系统基类

2.3 版本加入了 Entity 基类 和 DTO 基类，大家可以按需去继承和修改，代码路径

eladmin-common -> me.zhengjie.base

服务监控

异步线程池

该版本重写了spring默认线程池，代码地址：

eladmin-system -> me.zhengjie.config.thread.CustomExecutorConfig

源码如下：

@Configuration
public class CustomExecutorConfig {

    /**
     * 自定义线程池，用法 @Async
     * @return Executor
     */
    @Bean
    @Primary
    public Executor elAsync() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(AsyncTaskProperties.corePoolSize);
        executor.setMaxPoolSize(AsyncTaskProperties.maxPoolSize);
        executor.setQueueCapacity(AsyncTaskProperties.queueCapacity);
        executor.setThreadNamePrefix("el-async-");
        executor.setKeepAliveSeconds(AsyncTaskProperties.keepAliveSeconds);
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        executor.initialize();
        return executor;
    }

    /**
     * 自定义线程池，用法 @Async("otherAsync")
     * @return Executor
     */
    @Bean
    public Executor otherAsync() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(15);
        executor.setQueueCapacity(50);
        executor.setKeepAliveSeconds(AsyncTaskProperties.keepAliveSeconds);
        executor.setThreadNamePrefix("el-task-");
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        executor.initialize();
        return executor;
    }
}
