springboot线程池配置

拼搏现实的明天。 2022-11-18 04:34 198阅读 0赞

1. application.yml配置

\# 异步线程配置  
\# 配置核心线程数  
async.executor.thread.core\_pool\_size: 10  
\# 配置最大线程数  
async.executor.thread.max\_pool\_size: 20  
\# 配置队列大小  
async.executor.thread.queue\_capacity: 99999  
\# 配置线程池中的线程的名称前缀  
async.executor.thread.name.prefix: async-service-  
2. config配置类

@Configuration  
@EnableAsync  
public class ExecutorConfig \{

private static final Logger logger = LoggerFactory.getLogger(ExecutorConfig1.class);

@Value("$\{async.executor.thread.core\_pool\_size\}")  
    private int corePoolSize;  
    @Value("$\{async.executor.thread.max\_pool\_size\}")  
    private int maxPoolSize;  
    @Value("$\{async.executor.thread.queue\_capacity\}")  
    private int queueCapacity;  
    @Value("$\{async.executor.thread.name.prefix\}")  
    private String namePrefix;

@Bean(name = "asyncServiceExecutor")  
    public Executor asyncServiceExecutor() \{  
        logger.info("==============> start asyncServiceExecutor");  
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();  
        //配置核心线程数  
        executor.setCorePoolSize(corePoolSize);  
        //配置最大线程数  
        executor.setMaxPoolSize(maxPoolSize);  
        //配置队列大小  
        executor.setQueueCapacity(queueCapacity);  
        //配置线程池中的线程的名称前缀  
        executor.setThreadNamePrefix(namePrefix);

// rejection-policy：当pool已经达到max size的时候，如何处理新任务  
        // CALLER\_RUNS：不在新线程中执行任务，而是有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;  
    \}  
\}  
3. 调用, 直接在service方法上加注解

@Async("asyncServiceExecutor")  
public void checkWork(long eProjectId, String projectIds) \{  
\}
