Spring mvc cvc complex type.2.4.c：匹配的通配符是严格的，但是找不到元素'；构造函数arg'；

这是我的spring-security.xml

我得到了这个错误 cvc复杂类型.2.4.c:匹配的通配符是严格的，但找不到元素“构造函数arg”的声明。 -安全命名空间不支持元素[constructor arg]的修饰 -配置问题：安全命名空间不支持元素[constructor arg]的修饰有问题的资源：文件（项目路径） 我如何解决这个错误

。我想输入密码并检查密码是否与数据库密码匹配。

我认为问题在于

beans

不是默认名称空间。所以你可以试试

<beans:bean id="passwordEncoder" class="org.springframework.security.authentication.encoding.ShaPasswordEncoder">
 <beans:constructor-arg value="256"/>

或者将bean声明为默认名称空间

    <beans xmlns="http://www.springframework.org/schema/beans"
