解决方法

//添加----ThreadContext.bind(defaultWebSecurityManager);或SecurityUtils.setSecurityManager(defaultWebSecurityManager);问题解决
 @Bean
    public DefaultWebSecurityManager defaultWebSecurityManager() {
        //创建defaultWebSecurityManager
        DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager();
        //创建加密对象
        HashedCredentialsMatcher matcher = new HashedCredentialsMatcher();
        matcher.setHashAlgorithmName("MD5");
        matcher.setHashIterations(3);
        authRealm.setCredentialsMatcher(matcher);
        //将realm存入defaultWebSecurityManager
        defaultWebSecurityManager.setRealm(authRealm);
        SecurityUtils.setSecurityManager(defaultWebSecurityManager);
        //ThreadContext.bind(defaultWebSecurityManager);
        return defaultWebSecurityManager;
    }
