spring 定時任務、調用過程

網上介紹：http://gong1208.iteye.com/blog/1773177

一。常見用法：

1.任務類：

public class JobHandler {
	
	public void cleanLog() {
		logger.info("--開始執行刪除日誌任務--");
	}

}

2.spring xml配置：

	
	<!-- 工作的bean -->
	<bean id="cleanLog" class="com.core.util.JobHandler" />

	<!-- job的配置開始 -->
	<bean id="myJob" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<property name="targetObject">
			<ref bean="cleanLog" />
		</property>
		<property name="targetMethod" value="cleanLog">
		</property>
	</bean>
	<!-- job的配置結束 -->

	<!-- 調度的配置開始 -->
	<bean id="crontestJobTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail">
			<ref bean="myJob" />
		</property>
		<property name="cronExpression">
			<value>0 0 1 * * ?</value>
		</property>
	</bean>
	
	<!--
		cronExpression調度7個參數所代表的含義
		字段	 		允許值	 			允許的特殊字符
		秒	  		0-59	  			, - * /
		分	  		0-59	  			, - * /
		小時	  		0-23	  			, - * /
		日期	  		1-31	  			, - * ? / L W C
		月份	  		1-12 或者 JAN-DEC	<span style="white-space:pre">	</span>, - * /
		星期	  		1-7 或者 SUN-SAT	  	, - * ? / L C #
		年（可選）	<span style="white-space:pre">	</span>留空, 1970-2099		<span style="white-space:pre">	</span>, - * /
	-->
	<!-- 調度的配置結束 -->


	<!-- 啓動觸發器的配置開始 -->
	<bean name="startQuertz" lazy-init="false" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="crontestJobTrigger" />

			</list>
		</property>
	</bean>
	<!-- 啓動觸發器的配置結束 -->

二、實例一，定時調用存貯過程

1.xml定時配置

<!-- 每天2點自動跑存儲過程定時器 -->
	<bean id="bean" class="org.springframework.aop.framework.ProxyFactoryBean">
			<property name="target">
				<bean class="com.cc.Proc">
					<property name="jdbcTemplate">
						<ref bean="jdbcTemplate" />
					</property>
				</bean>
			</property>
			<property name="proxyTargetClass">
				<value>true</value>
			</property>
		</bean>   
	<bean id="executeProc" class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail">
			<bean
				class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
				<property name="targetObject" ref="bean" />
				<property name="targetMethod" value="executeProc" />
			</bean>
		</property>
		<property name="cronExpression">
			<value>0 0 2 * * ?</value>
		</property>
	</bean>
		
	<bean id="scheduler"
		class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
			 <!-- <ref bean="executeProc1" />-->
				<ref bean="executeProc" />
			</list>
		</property>
	</bean>

2.執行存儲過程類Proc

package com.cc;

import java.sql.CallableStatement;
import java.sql.SQLException;

import org.springframework.dao.DataAccessException;
import org.springframework.jdbc.core.CallableStatementCallback;
import org.springframework.jdbc.core.JdbcTemplate;

public class Proc{

    private JdbcTemplate jdbcTemplate;
    private String a;
    private String b;

    public void executeProc() {
	String sqlProc = "{call PROC(?,?,?,?)}";
	String strProc = (String) jdbcTemplate.execute(sqlProc, new CallableStatementCallback() {
	    @Override
	    public Object doInCallableStatement(CallableStatement cs) throws SQLException, DataAccessException {
		cs.setString(1, a);// 輸入參數
		cs.setString(2, b);// 輸入參數
		cs.registerOutParameter(3, java.sql.Types.VARCHAR);// 輸出參數
		cs.registerOutParameter(4, java.sql.Types.VARCHAR);// 輸出參數
		cs.execute();
		System.out.println("Proc code=" + cs.getString(3) + "：：：Proc message=" + cs.getString(4));
		return cs.getString(3);
	    }
	});
	System.out.println(strProc);
    }

    public JdbcTemplate getJdbcTemplate() {
	return jdbcTemplate;
    }

    public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
	this.jdbcTemplate = jdbcTemplate;
    }

    public String getA() {
	return this.a;
    }

    public void setA(String a) {
	this.a = a;
    }

    public String getB() {
	return this.b;
    }

    public void setB(String b) {
	this.b = b;
    }
}

3.執行的存儲過程PROC

CREATE OR REPLACE 
procedure PROC(a in varchar2,
               b in varchar2,
               code out varchar2,
               message out varchar2) is
  a1 varchar2(10);
  b1   varchar2(10);
begin
  a := to_char(to_date(a, 'yyyy-MM-dd') - 1,'yyyy-MM-dd');
  b   := to_char(to_date(b, 'yyyy-MM-dd'),'yyyy-MM-dd');
  
  code    := SQLCODE;
  msg := SUBSTR(SQLERRM, 1, 100);
  dbms_output.put_line(code || '::' || message);
end PROC;
