SSM整合SpringSecurity 时遇到的错误

1.在pom.xml加入SpringSecurity的依赖

<!-- SpringSecurity对Web应用进行权限管理 -->
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-web</artifactId>
            </dependency>
        
        <!-- SpringSecurity配置 -->
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-config</artifactId>
            </dependency>
        
        <!-- SpringSecurity标签库 -->
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-taglibs</artifactId>
            </dependency>
