1、问题描述

修改之前我的pom.xml文件如下，但是sec:authorize一直不生效。

        </dependency>
    </dependencies>

        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>

            </plugin>
        </plugins>
    </build>

</project>

2、解决方案：

将springsecurity的版本切换到5就行

代码语言：javascript复制

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.thymeleaf.extras/thymeleaf-extras-springsecurity5 -->
        <dependency>
            <groupId>org.thymeleaf.extras</groupId>
            <artifactId>thymeleaf-extras-springsecurity5</artifactId>
           <!-- <version>3.0.4.RELEASE</version>-->
        </dependency>

然后在thymeleaf的模板开头引入：

代码语言：javascript复制

<html xmlns:th="https://www.thymeleaf.org"
	  xmlns:sec="https://www.thymeleaf.org/thymeleaf-extras-springsecurity5">

重新启动项目，发现sec:authorize生效了

3、扩充

我发现换成springsecurity5之后，模板引擎的sec:authorize相关的所有标签没有补全提示了，但还能用，影响不大
