Today, the editor will share with you the relevant knowledge points about how to solve the problem of access control of springboot+shiro+thymeleaf page-level elements. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article.

Permission control of springboot+shiro+thymeleaf page-level elements

I use the springboot2.1 version.

Learned a lot of God's summary, basically the same, shiro permissions framework, front-end verification is designed for jsp, in which tag can only be used in the jsp series of template engines.

Using thymeleaf as the front-end template engine and using HTML files, it is impossible to introduce tag lib of shiro. At this time, if you want to use shiro, you can introduce thymeleaf-extras-shiro.jar as an extension package to realize the front-end verification of shiro.

Add the following dependencies to pom.xml:

Com.github.theborakompanioni thymeleaf-extras-shiro 1.2.1

Then, when configuring configuration for shiro, add

@ Beanpublic ShiroDialect shiroDialect () {return new ShiroDialect ();}

Then add xmlns to the page header of the page element you want to control:

Add user add interface has permission

No permission

The other configurations are the same as those used by shiro for background access control, and then that's fine. In fact, I did the same thing, but there was a problem.

Keep reporting this exception.

This exception means that the class AbstractTextChildModifierAttrProcessor can not be found. In fact, there is this class, but it can be found when compiling, so there is no exception, and this class cannot be found at run time, so it is abnormal. I checked it carefully many times. Finally, I changed the version of springboot, and then I did not report an error. At first, I used the latest version 2.0, and changed it to 1.5.

Here is a post about the package used by shiro

I hope the students who encounter the same problem will get around a hole.
