有兩種情況，第一種是業務邏輯復雜，但不需要業務邏輯的結果，第二種是需要返回業務邏輯的處理結果
第一種比較簡單，利用多線程處理業務邏輯，或者利用spring中@Asyn注解更簡單，
使用@Asyn注解，要首先要配置開啟異步注解
-
@Configuration
-
@EnableAsync
-
public
class AsyncConfig {
-
-
}
然后直接在方法上注解即可
-
@Service
-
public
class AsyncAction {
-
-
@Async
-
public void fun1() {
-
try {
-
Thread.sleep(
10000);
-
}
catch (InterruptedException e) {
-
// TODO Auto-generated catch block
-
e.printStackTrace();
-
}
-
System.out.println(
"fun1");
-
}
-
}
第二種需要返回業務邏輯情況則首先需要開啟異步支持
-
public
class SpitterWebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
-
@Override
-
protected void customizeRegistration(Dynamic registration) {
-
registration.setAsyncSupported(
true);
-
}
-
<servlet>
-
<servlet-name>SpringMvc
</servlet-name>
-
<servlet-class>org.springframework.web.servlet.DispatcherServlet
</servlet-class>
-
<init-param>
-
<param-name>contextConfigLocation
</param-name>
-
<param-value>...
</param-value>
-
</init-param>
-
<load-on-startup>1
</load-on-startup>
-
<async-supported>true
</async-supported>
-
</servlet>
然后配置一下線程池
-
@Configuration
-
@EnableWebMvc
-
@ComponentScan(
"spittr.web")
-
public
class WebConfig extends WebMvcConfigurerAdapter {
-
-
@Override
-
public void configureAsyncSupport(AsyncSupportConfigurer configurer) {
-
ThreadPoolTaskExecutor executor =
new ThreadPoolTaskExecutor();
-
executor.setCorePoolSize(
5);
-
executor.setMaxPoolSize(
10);
-
executor.setQueueCapacity(
50);
-
executor.setThreadNamePrefix(
"abc-");
-
executor.setKeepAliveSeconds(
30);
-
configurer.setTaskExecutor(executor);
-
configurer.setDefaultTimeout(
600);
-
}
-
@Configuration
-
@EnableWebMvc
-
@ComponentScan(
"spittr.web")
-
public
class WebConfig extends WebMvcConfigurerAdapter {
-
@RequestMapping(value =
"/async")
-
-
public
@ResponseBody
Callable<String> async() {
return new Callable<String>() {
@Override
public String call() throws Exception {
Thread.sleep(2000);
return "Callable result";
}
}; }
