基于quartz的定时任务(2)

datasource.setPassword(dbPassword); datasource.setMaxActive(maxConnections); datasource.setMinIdle(1);

datasource.setMaxWait(maxIdleSeconds);

datasource.setMaxOpenPreparedStatements(maxStatementsPerConnection);

if (dbValidationQuery != null) {

datasource.setValidationQuery(dbValidationQuery); if(!validateOnCheckout)

datasource.setTestOnBorrow(true); else

datasource.setTestOnReturn(true);

datasource.setTimeBetweenEvictionRunsMillis(idleValidationSeconds); } }

public Connection getConnection() throws SQLException { return datasource.getConnection(); }

public void shutdown() throws SQLException { datasource.close(); }

public void initialize() throws SQLException {

// do nothing, already initialized during constructor call newInstance try {

this.initialize(this.dbDriver, this.URL, this.dbUser, this.dbPassword,

maxConnections, this.maxStatementsPerConnection, this.dbValidationQuery, validateOnCheckout, this.idleValidationSeconds, maxIdleSeconds); } catch (SchedulerException e) {

// TODO Auto-generated catch block throw new SQLException(e); } }

public void setDriver(String dbDriver) { this.dbDriver = dbDriver; }

public void setURL(String URL) { this.URL = URL; }

public String getURL() { return URL; }

public void setUser(String dbUser) { this.dbUser = dbUser; }

public void setPassword(String dbPassword) { this.dbPassword = dbPassword; }

public void setMaxConnections(int maxConnections) {

this.maxConnections = maxConnections; }

public void setMaxCachedStatementsPerConnection(int maxStatementsPerConnection) {

this.maxStatementsPerConnection = maxStatementsPerConnection; }

public void setMaxIdleSeconds(int maxIdleSeconds) { this.maxIdleSeconds = maxIdleSeconds; }

public void setValidationQuery(String dbValidationQuery) { this.dbValidationQuery = dbValidationQuery; }

public void setIdleConnectionValidationSeconds(int idleValidationSeconds) { this.idleValidationSeconds = idleValidationSeconds; }

public void setValidateOnCheckout(boolean validateOnCheckout) { this.validateOnCheckout = validateOnCheckout; }

public void setDiscardIdleConnectionsSeconds(int maxIdleSeconds) { this.maxIdleSeconds = maxIdleSeconds; }

public void setDatasource(BasicDataSource datasource) { this.datasource = datasource; }

protected BasicDataSource getDataSource() { return datasource; } }

1.3 工具类对定时任务进行操作

主要是添加、修改、删除定时任务
