public DataSource dsDatasource(Environment env) throws Exception {
    HikariDataSource dataSource = new HikariDataSource();
    dataSource.setUsername(username);
    String password = env.getProperty(convertToHashicorpLabel());
    dataSource.setPassword(password != null ? password : dbPassword);
    if (dataSource.getPassword() == null) {
        throw new Exception("Datasource password is null");
    }
    dataSource.setJdbcUrl(url);
    dataSource.setDriverClassName(driverClassName);
    dataSource.setMaximumPoolSize(maxPoolSize);
    dataSource.setMinimumIdle(minPoolSize);
    dataSource.setPoolName(poolName);
    return dataSource;
}
private String convertToHashicorpLabel() {
    return username + "_label";
}

}
上面是java方法，当我运行checkmarx报告时，它在此行显示一个堆检查漏洞，字符串password=env.getproperty（converttohashicorplabel（））；。请帮我修一下好吗。
