  • java web spring异步方法

    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) {
            
        }
    
    }

    类上添加@EnableAsync, 方法上添加@Async, 

    添加@Service, 其他类可以注入这个实例,并调用成员方法

    注:有了解到,如果@Async修饰的方法和调用此方法的其他方法在同一个类中,不会生效
