This article introduces the knowledge of "how to integrate thymleaf template engine in Springboot". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. Getting started with thymeleaf

1.1 introducing coordinates

Org.springframework.boot spring-boot-starter-thymeleaf

1.2 write controller classes

@ GetMapping ("/ index") public String index (Model model) {model.addAttribute ("msg", "hello"); return "index";}

1.3 Front-end page

This address must be added to the html tag in the page, otherwise thymeleaf cannot be used, and this URL can only be written in the html tag. If you add another URL, it will cause a page exception.

Exception:

Wang Chao

The result is that the content "Wang Chao" in the cite tag is replaced by hello.

Th:text is one of the grammars of thymeleaf, and its function is to replace text. Whether there is content in the tag or not, it will be replaced with the stored content. At the same time, we should also note that thymeleaf is relatively strict, if the label can not take the value, it will report an error.

Common thymeleaf notes are as follows:

In actual development, because ModelAndView is request-level, if you want to display data on other pages, you need to use session for storage. The most common thing is to display user information on the index page after login.

2. Thymeleaf uses session built-in objects (not recommended)

2.1 controller Class

HttpServletRequest request = HttpContextUtil.getHttpServletRequest (); request.getSession () .setAttribute ("user", (SysUser) SecurityUtils.getSubject () .getPrincipal ())

2.2 Front desk page

Wang Chao

The name of the account I logged in is admin, so Wang Chao in the tag will be replaced with admin. If you use model, you cannot get the value of username, and the page will report an error. So you need to use session for session storage, but thymeleaf does not recommend using built-in objects.
