1 Update content1.1 Fixing defects

A) No prior consideration of the crawl process, an exception causes the crawl thread to terminate abnormally, but the resource is occupied. As the exception thread increases, the available resources are all occupied, the entire software stops working, and in the new version the exception is considered to release resources to ensure the uninterrupted nature of the crawl.

b) Change the method of updating the database to asynchronous mutually exclusive update mode, ensure that only one thread occupies the database at the same time, ensure the correctness of database data, and avoid sqlexception.

c) Accurate positioning of the target page, reducing the crawl failure rate and missus rate, to ensure the efficiency and correctness of the crawler.
