security遇到的问题

This may be the result of an unspecified view, due to default view name generation

解决方案

在pom文件中增加配置

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>

 java.lang.IllegalArgumentException: There is no PasswordEncoder mapped for the id "null"

解决方案

给密码加密

 thymeleaf整合springsecurity的依赖包

        <dependency>
            <groupId>org.thymeleaf.extras</groupId>
            <artifactId>thymeleaf-extras-springsecurity4</artifactId>
            <version>3.0.4.RELEASE</version>
        </dependency>

 

 导入thymeleaf-extras-springsecurity4后发现页面的sec:authorize="isAuthenticated()"不生效，然后就改为了thymeleaf-extras-springsecurity5

页面跳转失败，需要配置视图
