Spring Boot Quartz dynamic configuration, persistence

Quartz is a very powerful task scheduler framework SpringBoot is also very easy to integrate

Add dependence:

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
        </dependency>
        <!--Quartz-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-quartz</artifactId>
        </dependency>

Data Sources: We need to realize org.quartz.utils.ConnectionProvider method inside an interface with the database connection pool method is quite similar, Quartz will help us to inject various properties

Under normal circumstances it can be used Druid or C3p0 data sources, but has been integrated project C3p0 before we do not have to create a connection pool to obtain a connection pool instance of reflection can be directly shown: connnectionProvider is what we need

Posted the main code:

public class QuartzC3p0ConnectionProvider implements ConnectionProvider {

    //这些属性都会被注入，不过我们项目中已经有现成的连接池

    public String driver;
    //JDBC连接串
    public String URL;
    //数据库用户名
    public String user;

    public String password;
    //数据库最大连接数
    public int maxConnections;
    //数据库SQL查询每次连接返回执行到连接池，以确保它仍然是有效的。
    public String validationQuery;

    private C3P0ConnectionProvider c3P0ConnectionProvider;

    public QuartzC3p0ConnectionProvider() {
        try {
            Field sessionFactorField = MySqlClient.class.getDeclaredField("sessionFactory");
            sessionFactorField.setAccessible(true);

            Session session = sessionFactory.openSession();
            SessionImpl session1 = (SessionImpl) session;
            NonContextualJdbcConnectionAccess connectionAccess = (NonContextualJdbcConnectionAccess) session1.getJdbcConnectionAccess();
            Field providerField = connectionAccess.getClass().getDeclaredField("connectionProvider");
            providerField.setAccessible(true);
            c3P0ConnectionProvider = (C3P0ConnectionProvider) providerField.get(connectionAccess);
        } catch (NoSuchFieldException e) {
            e.printStackTrace();
            System.exit(-1);
        } catch (IllegalAccessException e) {
            e.printStackTrace();

But this created out of the Job lifecycle management is not Spring, you can not use dependency injection, if needed to support dependency injection will take some other action
