CustomRealm customRealm = new CustomRealm();

// 哈希凭证匹配器
HashedCredentialsMatcher hashedCredentialsMatcher = new HashedCredentialsMatcher();
hashedCredentialsMatcher.setHashAlgorithmName("md5");
hashedCredentialsMatcher.setHashIterations(1);
customRealm.setCredentialsMatcher(hashedCredentialsMatcher);

// 1.构建SecurityManager环境
DefaultSecurityManager defaultSecurityManager = new DefaultSecurityManager();
defaultSecurityManager.setRealm(customRealm);

// 2.主体提交认证请求
SecurityUtils.setSecurityManager(defaultSecurityManager);
