Java web spring异步方法实现步骤解析

在项目中，时常会有异步调用的需求

web.xml配置

									<servlet>

									  <description>spring mvc servlet</description>

									  <servlet-name>springMvc</servlet-name>

									  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

									  <init-param>

									   <description>spring mvc 配置文件</description>

									   <param-name>contextConfigLocation</param-name>

									   <param-value>classpath:spring-mvc.xml</param-value>

									  </init-param>

									  <load-on-startup>1</load-on-startup>

									  <async-supported>true</async-supported>

									 </servlet>

									 <servlet-mapping>

									  <servlet-name>springMvc</servlet-name>

									  <url-pattern>/</url-pattern>

									 </servlet-mapping>

添加：<async-supported>true</async-supported>

spring xml添加配置：

									<!-- 支持异步方法执行 -->

									<task:executor id="myExecutor" pool-size="10" />

									<task:annotation-driven executor="myExecutor"/>

然后demo:

									@Service

									@EnableAsync

									public class DevicesEditLogService {

									  @Async

									  public void recordEditLog(Map<String, Object> param) {

									  }

									}
