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

        
            org.springframework.boot
            spring-boot-starter-thymeleaf
        

 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

        
            org.thymeleaf.extras
            thymeleaf-extras-springsecurity4
            3.0.4.RELEASE
        

 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
