1、修改spring配置文件applicationContext.xml:
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation=“http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd”
<bean class="com.hmnet.common.TaskJob" name="taskJob"></bean>
<task:scheduled-tasks>
<!--
"0 0/0 * * * ?" 整点调用,就如时间整点报钟一样。
"0 0/1 * * * ?" 每1分钟调用一次,每几分钟调用改“1”对应的位置就OK啦。
"10 0/5 * * * ?" 每5分钟之后的10秒时调用。例如:10:00:10 am, 10:05:10 am,10:10:10 am,10:15:10 am........................
"0 30 10-13 ? * WED,FRI" 在星期三到星期五的10:30, 11:30, 12:30, and 13:30调用。
"0 0/30 8-9 5,20 * ?" 在每个月的5号和20号,在上午 8:00, 8:30, 9:00 and 9:30会被调用。
-->
<task:scheduled ref="taskJob" method="doMyJob" cron="0 0/50 * * * ?"/>
</task:scheduled-tasks>
<context:component-scan base-package=" com.hmnet.common " />
2、新建工作类
package com.hmnet.common;
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
public class TaskJob{
@Autowired
DataSource dataSource;
public DataSource getDataSource() {
return dataSource;
}
public void setDataSource(DataSource dataSource) {
this.dataSource = dataSource;
}
public void doMyJob(){
Connection connection=null;
try {
connection = dataSource.getConnection();
} catch (SQLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Statement statement=null;
try {
String sql = "";
sql = "update SERIAL_NUMBER t set t.IS_TEMP_BUSY = '0' where t.IS_EMPTY = '0' and t.IS_TEMP_BUSY = '1'";
statement=connection.createStatement();
statement.executeUpdate(sql);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally{
try {
if(null!=statement){
statement.close();
}
if(null!=connection){
connection.close();
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
System.out.println("每隔一段时间,此方法会被调用一次");
}
}
