Spring为任务调度与异步方法执行提供了注解支持。通过在方法上设置@Async注解,可使得方法被异步调用。也就是说调用者会在调用时立即返回,而被调用方法的实际执行是交给Spring的TaskExecutor来完成。
Spring异步配置
<!-- 异步配置 -->
<task:annotation-driven executor="myExecutor"/>
<task:executor id="myExecutor" pool-size="5-25" queue-capacity="100" rejection-policy="CALLER_RUNS"/>
同时在xml的配置文件中要增加标签的定义
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.1.xsd
http://www.springframework.org/schema/mvc

使用@Async实现异步执行
@Service
public class APILogServiceImpl implements IAPILogService {
@Async
public void saveAPILog(String taskId, String accountId, String accountName, String apiId, String apiUrl, String parameter,
String result) {
......
}
}
这样在其他地方调用该方法的时候就可以实现异步执行
//记录查询日志
apiLogService.saveAPILog(taskId, accountId, accountName, apiId, url, parameter, JSONObject.toJSONString(result));
