Guo Tai — public information about this author is limited. At present, only one work by this author is known, SSH Framework Enterprise Application in Practice, which falls under programming and design. Judging from the title, the book addresses enterprise-level Java application development and offers hands-on explanation centered on the SSH stack — the combination of the three open-source frameworks Struts, Spring, and Hibernate. Books of this kind generally serve developers who already have some Java foundation and want to apply framework knowledge to real projects, so they tend to focus on configuration points, integration workflows, and case implementations rather than broad conceptual surveys. Since no reliable record of the author's education, professional background, or career experience is available, no speculation is offered here, nor are any technical titles or industry roles invented. Readers interested in the practical use of enterprise Java frameworks may treat this work as one reference in that direction; regarding the author personally, it is best to stay within the limits of the work itself and remain cautious.
