我正在使用Java编写red5应用程序,并使用c3p0进行数据库交互。
似乎在MySQL服务器中连接超时后,我的应用程序停止工作,并提示配置autoreconnect=true。
我该怎么做呢?
这是我用来创建数据源的函数:
private ComboPooledDataSource _createDataSource() {
Properties props = new Properties();
// Looks for the file 'database.properties' in {TOMCAT_HOME}\webapps\{RED5_HOME}\WEB-INF\
try {
FileInputStream in = new FileInputStream(System.getProperty("red5.config_root") + "/database.properties");
props.load(in);
in.close();
} catch (IOException ex) {
log.error("message: {}", ex.getMessage());
log.error("stack trace: " + ExceptionUtils.getFullStackTrace(ex));
return null;
}
// It will load the driver String from properties
String drivers = props.getProperty("jdbc.drivers");
String url = props.getProperty("jdbc.url");
String username = props.getProperty("jdbc.username");
String password = props.getProperty("jdbc.password");
ComboPooledDataSource cpds = new ComboPooledDataSource();
try {
cpds.setDriverClass(drivers);
} catch (PropertyVetoException ex) {
log.error("message: {}", ex.getMessage());
log.error("stack trace: " + ExceptionUtils.getFullStackTrace(ex));
return null;
}
cpds.setJdbcUrl(url);
cpds.setUser(username);
cpds.setPassword(password);
cpds.setMaxStatements(180);
return cpds;
}
