Spring整合Quartz
1、quartz調(diào)度框架是有內(nèi)置表的
進入quartz的官網(wǎng)http://www.quartz-scheduler.org/，點擊Downloads
下載quartz-2.2.3-distribution.tar
下載后在目錄\docs\dbTables下有常用數(shù)據(jù)庫創(chuàng)建quartz表的腳本
例如：“tables_mysql.sql”
table_mysql.sql
table_mysql_innodb.sql
上述兩者所有的數(shù)據(jù)庫引擎不一樣
在數(shù)據(jù)庫里導入table_mysql.sql內(nèi)置表
2、創(chuàng)建工程
導入pom依賴和逆向生成插件
generatorConfig.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN""http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" > <generatorConfiguration><!-- 引入配置文件 --><properties resource="jdbc.properties"/><!--指定數(shù)據(jù)庫jdbc驅(qū)動jar包的位置--><classPathEntry location="D:\\tools\\mvn\\mysql\\mysql-connector-java\\5.1.44\\mysql-connector-java-5.1.44.jar"/><!-- 一個數(shù)據(jù)庫一個context --><context id="infoGuardian"><!-- 注釋 --><commentGenerator><property name="suppressAllComments" value="true"/><!-- 是否取消注釋 --><property name="suppressDate" value="true"/> <!-- 是否生成注釋代時間戳 --></commentGenerator><!-- jdbc連接 --><jdbcConnection driverClass="${jdbc.driver}"connectionURL="${jdbc.url}" userId="${jdbc.username}" password="${jdbc.password}"/><!-- 類型轉(zhuǎn)換 --><javaTypeResolver><!-- 是否使用bigDecimal， false可自動轉(zhuǎn)化以下類型（Long, Integer, Short, etc.） --><property name="forceBigDecimals" value="false"/></javaTypeResolver><!-- 01 指定javaBean生成的位置 --><!-- targetPackage：指定生成的model生成所在的包名 --><!-- targetProject：指定在該項目下所在的路徑 --><javaModelGenerator targetPackage="com.xwt.quartz02.model"targetProject="src/main/java"><!-- 是否允許子包，即targetPackage.schemaName.tableName --><property name="enableSubPackages" value="false"/><!-- 是否對model添加構造函數(shù) --><property name="constructorBased" value="true"/><!-- 是否針對string類型的字段在set的時候進行trim調(diào)用 --><property name="trimStrings" value="false"/><!-- 建立的Model對象是否 不可改變 即生成的Model對象不會有 setter方法，只有構造方法 --><property name="immutable" value="false"/></javaModelGenerator><!-- 02 指定sql映射文件生成的位置 --><sqlMapGenerator targetPackage="com.xwt.quartz02.mapper"targetProject="src/main/java"><!-- 是否允許子包，即targetPackage.schemaName.tableName --><property name="enableSubPackages" value="false"/></sqlMapGenerator><!-- 03 生成XxxMapper接口 --><!-- type="ANNOTATEDMAPPER",生成Java Model 和基于注解的Mapper對象 --><!-- type="MIXEDMAPPER",生成基于注解的Java Model 和相應的Mapper對象 --><!-- type="XMLMAPPER",生成SQLMap XML文件和獨立的Mapper接口 --><javaClientGenerator targetPackage="com.xwt.quartz02.mapper"targetProject="src/main/java" type="XMLMAPPER"><!-- 是否在當前路徑下新加一層schema,false路徑com.oop.eksp.user.model， true:com.oop.eksp.user.model.[schemaName] --><property name="enableSubPackages" value="false"/></javaClientGenerator><!-- 配置表信息 --><table schema="" tableName="t_schedule_trigger" domainObjectName="ScheduleTrigger"enableCountByExample="false" enableDeleteByExample="false"enableSelectByExample="false" enableUpdateByExample="false"><property name="useActualColumnNames" value="true" /></table><table schema="" tableName="t_schedule_trigger_param" domainObjectName="ScheduleTriggerParam"enableCountByExample="false" enableDeleteByExample="false"enableSelectByExample="false" enableUpdateByExample="false"><property name="useActualColumnNames" value="true" /></table></context> </generatorConfiguration>jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/demo?useUnicode=true&characterEncoding=UTF-8 jdbc.username=root jdbc.password=1233、在項目中添加quartz.properties文件(這樣就不會加載自帶的properties文件)
此文件的內(nèi)容主要分為：scheduler，ThreadPool，JobStore，plugin，Datasources等部分
覆蓋properties文件的目的是覆蓋默認的數(shù)據(jù)源，更換為druid的數(shù)據(jù)配置
quartz.properties
重寫數(shù)據(jù)源的連接去更換
DruidConnectionProvider.java
package com.xwt.quartz02.util;import com.alibaba.druid.pool.DruidDataSource; import org.quartz.SchedulerException; import org.quartz.utils.ConnectionProvider;import java.sql.Connection; import java.sql.SQLException;public class DruidConnectionProvider implements ConnectionProvider {/** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~** 常量配置，與quartz.properties文件的key保持一致(去掉前綴)，同時提供set方法，Quartz框架自動注入值。** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*///JDBC驅(qū)動public String driver;//JDBC連接串public String URL;//數(shù)據(jù)庫用戶名public String user;//數(shù)據(jù)庫用戶密碼public String password;//數(shù)據(jù)庫最大連接數(shù)public int maxConnection;//數(shù)據(jù)庫SQL查詢每次連接返回執(zhí)行到連接池，以確保它仍然是有效的。public String validationQuery;private boolean validateOnCheckout;private int idleConnectionValidationSeconds;public String maxCachedStatementsPerConnection;private String discardIdleConnectionsSeconds;public static final int DEFAULT_DB_MAX_CONNECTIONS = 10;public static final int DEFAULT_DB_MAX_CACHED_STATEMENTS_PER_CONNECTION = 120;//Druid連接池private DruidDataSource datasource;/** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~** 接口實現(xiàn)** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*/public Connection getConnection() throws SQLException {return datasource.getConnection();}public void shutdown() throws SQLException {datasource.close();}public void initialize() throws SQLException{if (this.URL == null) {throw new SQLException("DBPool could not be created: DB URL cannot be null");}if (this.driver == null) {throw new SQLException("DBPool driver could not be created: DB driver class name cannot be null!");}if (this.maxConnection < 0) {throw new SQLException("DBPool maxConnectins could not be created: Max connections must be greater than zero!");}datasource = new DruidDataSource();try{datasource.setDriverClassName(this.driver);} catch (Exception e) {try {throw new SchedulerException("Problem setting driver class name on datasource: " + e.getMessage(), e);} catch (SchedulerException e1) {}}datasource.setUrl(this.URL);datasource.setUsername(this.user);datasource.setPassword(this.password);datasource.setMaxActive(this.maxConnection);datasource.setMinIdle(1);datasource.setMaxWait(0);datasource.setMaxPoolPreparedStatementPerConnectionSize(this.DEFAULT_DB_MAX_CACHED_STATEMENTS_PER_CONNECTION);if (this.validationQuery != null) {datasource.setValidationQuery(this.validationQuery);if(!this.validateOnCheckout)datasource.setTestOnReturn(true);elsedatasource.setTestOnBorrow(true);datasource.setValidationQueryTimeout(this.idleConnectionValidationSeconds);}}/** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~** 提供get set方法** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*/public String getDriver() {return driver;}public void setDriver(String driver) {this.driver = driver;}public String getURL() {return URL;}public void setURL(String URL) {this.URL = URL;}public String getUser() {return user;}public void setUser(String user) {this.user = user;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public int getMaxConnection() {return maxConnection;}public void setMaxConnection(int maxConnection) {this.maxConnection = maxConnection;}public String getValidationQuery() {return validationQuery;}public void setValidationQuery(String validationQuery) {this.validationQuery = validationQuery;}public boolean isValidateOnCheckout() {return validateOnCheckout;}public void setValidateOnCheckout(boolean validateOnCheckout) {this.validateOnCheckout = validateOnCheckout;}public int getIdleConnectionValidationSeconds() {return idleConnectionValidationSeconds;}public void setIdleConnectionValidationSeconds(int idleConnectionValidationSeconds) {this.idleConnectionValidationSeconds = idleConnectionValidationSeconds;}public DruidDataSource getDatasource() {return datasource;}public void setDatasource(DruidDataSource datasource) {this.datasource = datasource;} }4、自定義MyJobFactory 解決spring不能在quartz中注入bean的問題
package com.xwt.quartz02.quartz;import lombok.extern.slf4j.Slf4j; import org.quartz.spi.TriggerFiredBundle; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.config.AutowireCapableBeanFactory; import org.springframework.scheduling.quartz.AdaptableJobFactory; import org.springframework.stereotype.Component;@Component @Slf4j public class MyJobFactory extends AdaptableJobFactory {//這個由Spring自動注入@Autowiredprivate AutowireCapableBeanFactory autowireCapableBeanFactory;//重寫Job任務對象的創(chuàng)建實例方法@Overrideprotected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {Object jobInstance = super.createJobInstance(bundle);//通過以下方式 解決Job任務無法使用Spring中的Bean問題autowireCapableBeanFactory.autowireBean(jobInstance);return jobInstance;} }5、創(chuàng)建調(diào)度器schedule 交給spring進行管理
QuartzConfiguration.java（quartz調(diào)度框架與spring框架整合的配置類 主要是要將org.quartz.Scheduler交給spring進行管理）
package com.xwt.quartz02.quartz;import org.quartz.Scheduler; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.config.PropertiesFactoryBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.core.io.ClassPathResource; import org.springframework.scheduling.quartz.SchedulerFactoryBean;import java.io.IOException; import java.util.Properties;@Configuration public class QuartzConfiguration {@Autowiredprivate MyJobFactory myJobFactory;//創(chuàng)建調(diào)度器工廠@Beanpublic SchedulerFactoryBean schedulerFactoryBean(){//1.創(chuàng)建SchedulerFactoryBean//2.加載自定義的quartz.properties配置文件//3.設置MyJobFactorySchedulerFactoryBean factoryBean=new SchedulerFactoryBean();try {factoryBean.setQuartzProperties(quartzProperties());factoryBean.setJobFactory(myJobFactory);return factoryBean;} catch (IOException e) {throw new RuntimeException(e);}}@Beanpublic Properties quartzProperties() throws IOException {PropertiesFactoryBean propertiesFactoryBean=new PropertiesFactoryBean();propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));propertiesFactoryBean.afterPropertiesSet();return propertiesFactoryBean.getObject();}@Bean(name="scheduler")public Scheduler scheduler(){return schedulerFactoryBean().getScheduler();} }配置application.yml
