从Liferay DXP 7.2升级到7.4：OpenIdConnectUserInfoProcessor接口无法识别求助

核心替代方案：自定义 OIDCUserMapper #

Liferay DXP 7.4中已移除OpenIdConnectUserInfoProcessor接口，官方改用OIDCUserMapper接口处理OpenID Connect用户数据映射逻辑，实现步骤如下：

• 实现com.liferay.portal.security.sso.openid.connect.internal.mapper.OIDCUserMapper接口，核心重写mapUserInfo方法，完成第三方用户信息到Liferay User对象的映射。
• 示例代码片段：

import com.liferay.portal.security.sso.openid.connect.internal.mapper.OIDCUserMapper;
import com.liferay.portal.security.sso.openid.connect.OpenIdConnectUserInfo;
import com.liferay.portal.kernel.model.User;
import com.liferay.portal.kernel.service.UserLocalService;
import org.osgi.service.component.annotations.Reference;

public class CustomOIDCUserMapper implements OIDCUserMapper {

    @Reference
    private UserLocalService _userLocalService;

    @Override
    public User mapUserInfo(OpenIdConnectUserInfo openIdConnectUserInfo, long companyId, long creatorUserId) throws Exception {
        // 提取OIDC返回的用户数据
        String email = openIdConnectUserInfo.getEmail();
        String fullName = openIdConnectUserInfo.getFullName();
        // 自定义属性可通过getAttributes获取
        String customAttr = openIdConnectUserInfo.getAttributes().get("custom_attr");

        // 检查用户是否已存在，按需创建或更新
        User existingUser = _userLocalService.fetchUserByEmailAddress(companyId, email);
        
        if (existingUser == null) {
            // 创建新用户逻辑
            return _userLocalService.addUser(
                creatorUserId, companyId, false, "temp_pwd", "temp_pwd",
                false, openIdConnectUserInfo.getSubject(), email, 0, "", 
                Locale.getDefault(), fullName.split(" ")[0], "", fullName.split(" ")[1],
                0, 0, true, 1, 1, 1970, null, null, null, null, false, null
            );
        } else {
            // 更新现有用户逻辑
            existingUser.setFullName(fullName);
            existingUser.setExpandoBridgeAttribute("customAttr", customAttr);
            return _userLocalService.updateUser(existingUser);
        }
    }
}

注册自定义Mapper #

将自定义Mapper注册为OSGi服务，通过设置service.ranking优先级覆盖默认实现：

import org.osgi.service.component.annotations.Component;

@Component(
    immediate = true,
    property = {"service.ranking:Integer=100"},
    service = OIDCUserMapper.class
)
public class CustomOIDCUserMapper implements OIDCUserMapper {
    // 实现代码同上
}

额外注意事项 #

• 确保项目依赖中已引入com.liferay.portal.security.sso.openid.connect.api和com.liferay.portal.kernel包。
• 若需处理OIDC返回的自定义扩展属性，可通过OpenIdConnectUserInfo.getAttributes()获取全部属性后进行映射。
