Spring boot 2.0 jump to jsp tutorial https://blog.csdn.net/q18771811872/article/details/88342298
Explain. Integration issues,
1. The return template of springboot will jump to html by default after the pom.xml file is put into the thymeleaf package and jsp support,
Even if you don't configure the properties of thmeleaf
Solution: use getRequestDispatcher method to jump to jsp page, and support html and jsp at the same time
request.getRequestDispatcher("/WEB-INF/views/testJsp.jsp").forward(request, response);
2. In addition, when using getRequestDispatcher to jump to the html page, there may be problems with the receiving parameters of the thmeleaf template.
Solution 1: html abandons the use of thmeleaf template, and then actively requests interface data on the page (AJAX POST, etc.)
Solution 2: html continues to use the thmeleaf template, and return s the template to jump to the page

That's all.
In addition, a return template java code configuration is attached. You can configure the priority of the return template. The following file format, of course, can only be skipped by getRequestDispatcher
In addition, the profile parameters and code can be repeated, but the code takes precedence over the profile.

InternalResourceViewResolver internalResourceViewResolver = new InternalResourceViewResolver();
internalResourceViewResolver.setPrefix("/WEB-INF/");//prefix

return internalResourceViewResolver;
}
