This article mainly introduces "how to use the basic objects of Thymeleaf". In the daily operation, I believe that many people have doubts about how to use the basic objects of Thymeleaf. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "how to use the basic objects of Thymeleaf". Next, please follow the editor to study!

There are many built-in objects in Thymeleaf that can implement various functions in templates.

Here are a few basic objects.

Web objects are commonly used: request, session, servletContext.

Thymeleaf provides several built-in variables param, session, and application, which can access the request parameter, the session attribute, and the application attribute, respectively.

All properties of request can be accessed directly using ${attribute name}.

Note: built-in objects and built-in variables are two concepts. Built-in objects use the form of "${# object}", while built-in variables do not need "#".

Development environment: IntelliJ IDEA 2019.2.2

Spring Boot version: 2.1.8

Create a new Spring Boot project named demo.

1. Pom.xml joins Thymeleaf dependency:

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

2 、 src/main/resources/templates/test1.html

The above can also be changed into the following ways:

3 、 src/main/java/com/example/demo/Test1Controller.java

Package com.example.demo;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import javax.servlet.http.HttpServletRequest;@Controllerpublic class Test1Controller {@ RequestMapping ("/ test1") public String test1 (@ RequestParam String name1, HttpServletRequest request) {request.setAttribute ("name2", "b"); request.getSession () .setAttribute ("name3", "c") Request.getServletContext () .setAttribute ("name4", "d"); return "test1";}

Browser access: http://localhost:8080/test1?name1=a

Page output:

Abcd can also be replaced with the following way: bcd at this point, the study on "how to use the basic objects of Thymeleaf" is over, I hope to be able to solve your doubts.
