  Oinone登录扩展：对接SSO(适应于4.7.8及之后的版本)

  适配版本 4.7.8及其之后的版本 概述 在企业内部，对于已有一套完整的登录系统(SSO)的情况下，通常会要求把所有的系统都对接到SSO中；本文主要讲解用Oinone开发的项目对接SSO的具体实现。 对接步骤 1、项目自定义实现UserCookieLogin，可参考示例说明： pro.shushi.pamirs.user.api.login.UserCookieLoginFree 2、对接SSO示例 对接流程说明： 1）【必须】从请求头Header或者Query中获取到token； 2）【必须】去SSO服务端验证token的有效性； 3）【可选】根据token去服务端获取用户信息；如果token可以直接反解析出用户信息，则该步骤忽略； 4）【可选】根据实际情况用户信息是否进行DB的存储； 5）【必须】验证token有效后，生成Session和Cookie（即token换cookie）； 注意超时时间需要 <= SSO服务端token失效时间。 package pro.shushi.pamirs.demo.core.sso; import com.alibaba.fastjson.JSON; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.core.annotation.Order; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.stereotype.Component; import org.springframework.web.context.request.RequestContextHolder; import org.springframework.web.context.request.ServletRequestAttributes; import pro.shushi.pamirs.demo.core.sso.constant.HttpConstant; import pro.shushi.pamirs.demo.core.sso.constant.SessionUserTypeEnum; import pro.shushi.pamirs.demo.core.sso.model.ApiCommonTransient; import pro.shushi.pamirs.demo.core.sso.model.PermissionInfoResp; import pro.shushi.pamirs.demo.core.sso.utils.AuthenticateUtils; import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j; import pro.shushi.pamirs.meta.api.dto.model.PamirsUserDTO; import pro.shushi.pamirs.meta.api.session.PamirsSession; import pro.shushi.pamirs.meta.common.exception.PamirsException; import pro.shushi.pamirs.meta.common.spring.BeanDefinitionUtils; import pro.shushi.pamirs.resource.api.enmu.UserSignUpType; import pro.shushi.pamirs.user.api.cache.UserCache; import pro.shushi.pamirs.user.api.constants.UserConstant; import pro.shushi.pamirs.user.api.enmu.UserExpEnumerate; import pro.shushi.pamirs.user.api.enmu.UserLoginTypeEnum; import pro.shushi.pamirs.user.api.login.IUserLoginChecker; import pro.shushi.pamirs.user.api.login.UserCookieLogin; import pro.shushi.pamirs.user.api.login.UserCookieLoginSimple; import pro.shushi.pamirs.user.api.model.PamirsUser; import pro.shushi.pamirs.user.api.model.tmodel.PamirsUserTransient; import pro.shushi.pamirs.user.api.service.UserService; import pro.shushi.pamirs.user.api.utils.CookieUtil; import javax.servlet.http.HttpServletResponse; /** * * @author shushi * * 完全自定义login的过程 * 需要实现登陆部分login 以及拦截部分fetchUserIdByReq * 如果fetchUserIdByReq返回值为null的时候 将会被拦截 */ @Slf4j @Order(0) @Component public class DemoUserSSOCookieLogin extends UserCookieLogin<PamirsUser> { //刷新令牌 private static String REFRESH_TOKEN = "refreshToken"; //系统id private static String CLIENT_ID = "client-id"; //访问令牌 private static String AUTHORIZATION = "Authorization"; private IUserLoginChecker checker; @Autowired private UserService userService; @Autowired private RedisTemplate<String, String> redisTemplate; @Override public String type() { return UserLoginTypeEnum.COOKIE.value(); } @Override public PamirsUser resolveAndVerification(PamirsUserTransient user) { if (checker == null) { checker = BeanDefinitionUtils.getBean(IUserLoginChecker.class); } return checker.check4login(user); } /** * 重写登录拦截功能 * 该函数主要作用,通过三方权限校验. * @return */ // 版本升级需要修改 @Override public PamirsUserDTO fetchUserIdByReq() { String sessionId =…

  如何自定义Excel导出功能

  介绍 在平台提供的默认导出功能无法满足业务需求的时候，我们可以自定义导出功能，以满足业务中个性化的需求。 功能示例 继承平台的导出任务模型，加上需要在导出的弹窗视图需要展示的字段 package pro.shushi.pamirs.demo.api.model; import pro.shushi.pamirs.file.api.model.ExcelExportTask; import pro.shushi.pamirs.meta.annotation.Field; import pro.shushi.pamirs.meta.annotation.Model; @Model.model(DemoItemExportTask.MODEL_MODEL) @Model(displayName = "商品-Excel导出任务") public class DemoItemExportTask extends ExcelExportTask { public static final String MODEL_MODEL = "demo.DemoItemExportTask"; // 自定义显示的字段 @Field.String @Field(displayName = "发布人") private String publishUserName; } 编写自定义导出弹窗视图的数据初始化方法和导出提交的action package pro.shushi.pamirs.demo.core.action; import org.springframework.stereotype.Component; import pro.shushi.pamirs.demo.api.model.DemoItemExportTask; import pro.shushi.pamirs.file.api.action.ExcelExportTaskAction; import pro.shushi.pamirs.file.api.model.ExcelWorkbookDefinition; import pro.shushi.pamirs.file.api.service.ExcelFileService; import pro.shushi.pamirs.meta.annotation.Action; import pro.shushi.pamirs.meta.annotation.Function; import pro.shushi.pamirs.meta.annotation.Model; import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j; import pro.shushi.pamirs.meta.enmu.ActionContextTypeEnum; import pro.shushi.pamirs.meta.enmu.FunctionOpenEnum; import pro.shushi.pamirs.meta.enmu.FunctionTypeEnum; import pro.shushi.pamirs.meta.enmu.ViewTypeEnum; @Slf4j @Component @Model.model(DemoItemExportTask.MODEL_MODEL) public class DemoItemExcelExportTaskAction extends ExcelExportTaskAction { public DemoItemExcelExportTaskAction(ExcelFileService excelFileService) { super(excelFileService); } @Action(displayName = "导出", contextType = ActionContextTypeEnum.CONTEXT_FREE, bindingType = {ViewTypeEnum.TABLE}) public DemoItemExportTask createExportTask(DemoItemExportTask data) { if (data.getWorkbookDefinitionId() != null) { ExcelWorkbookDefinition workbookDefinition = new ExcelWorkbookDefinition(); workbookDefinition.setId(data.getWorkbookDefinitionId()); data.setWorkbookDefinition(workbookDefinition); } super.createExportTask(data); return data; } /** * @param data * @return */ @Function(openLevel = FunctionOpenEnum.API) @Function.Advanced(type = FunctionTypeEnum.QUERY) public DemoItemExportTask construct(DemoItemExportTask data) { data.construct(); return data; } } 编写导出的数据处理逻辑，此处可以拿到导出弹窗内自定义的字段提交的值，然后根据这些值处理自定义逻辑 package pro.shushi.pamirs.demo.core.excel.extPoint; import org.springframework.stereotype.Component; import pro.shushi.pamirs.demo.api.model.DemoItem; import pro.shushi.pamirs.demo.api.model.DemoItemExportTask; import pro.shushi.pamirs.demo.api.model.DemoItemImportTask; import pro.shushi.pamirs.file.api.context.ExcelDefinitionContext; import pro.shushi.pamirs.file.api.enmu.ExcelTemplateTypeEnum; import pro.shushi.pamirs.file.api.extpoint.ExcelExportFetchDataExtPoint; import pro.shushi.pamirs.file.api.extpoint.impl.ExcelExportSameQueryPageTemplate; import pro.shushi.pamirs.file.api.model.ExcelExportTask; import pro.shushi.pamirs.file.api.model.ExcelWorkbookDefinition; import pro.shushi.pamirs.file.api.util.ExcelHelper; import pro.shushi.pamirs.file.api.util.ExcelTemplateInit; import pro.shushi.pamirs.meta.annotation.ExtPoint; import java.util.Collections; import java.util.List; @Component public class DemoItemExportExtPoint extends ExcelExportSameQueryPageTemplate implements ExcelTemplateInit , ExcelExportFetchDataExtPoint…

  如何自定义SQL(Mapper)语句

  场景描述 在实际业务场景中，存在复杂SQL的情况，具体表现为： 单表单SQL满足不了的情况下 有复杂的Join关系或者子查询 复杂SQL的逻辑通过程序逻辑难以实现或实现代价较大 在此情况下，通过原生的mybatis/mybatis-plus, 自定义Mapper的方式实现业务功能 1、编写所需的Mapper SQL Mapper写法无限制，与使用原生的mybaits/mybaits-plus用法一样； Mapper(DAO)和SQL可以写在一个文件中，也分开写在两个文件中。 package pro.shushi.pamirs.demo.core.map; import org.apache.ibatis.annotations.Mapper; import org.apache.ibatis.annotations.Param; import org.apache.ibatis.annotations.Select; import java.util.List; import java.util.Map; @Mapper public interface DemoItemMapper { @Select("<script>select sum(item_price) as itemPrice,sum(inventory_quantity) as inventoryQuantity,categoryId from ${demoItemTable} as core_demo_item ${where} group by category_id</script>") List<Map<String, Object>> groupByCategoryId(@Param("demoItemTable") String pamirsUserTable, @Param("where") String where); } 2.调用mapper 调用Mapper代码示例 package pro.shushi.pamirs.demo.core.map; import com.google.api.client.util.Lists; import org.springframework.stereotype.Component; import pro.shushi.pamirs.demo.api.model.DemoItem; import pro.shushi.pamirs.framework.connectors.data.api.datasource.DsHintApi; import pro.shushi.pamirs.meta.api.core.orm.convert.DataConverter; import pro.shushi.pamirs.meta.api.session.PamirsSession; import pro.shushi.pamirs.meta.common.spring.BeanDefinitionUtils; import java.util.List; import java.util.Map; @Component public class DemoItemDAO { public List<DemoItem> customSqlDemoItem(){ try (DsHintApi dsHint = DsHintApi.model(DemoItem.MODEL_MODEL)) { String demoItemTable = PamirsSession.getContext().getModelCache().get(DemoItem.MODEL_MODEL).getTable(); DemoItemMapper demoItemMapper = BeanDefinitionUtils.getBean(DemoItemMapper.class); String where = " where status = 'ACTIVE'"; List<Map<String, Object>> dataList = demoItemMapper.groupByCategoryId(demoItemTable,where); DataConverter persistenceDataConverter = BeanDefinitionUtils.getBean(DataConverter.class); return persistenceDataConverter.out(DemoItem.MODEL_MODEL, dataList); } return Lists.newArrayList(); } } 调用Mapper一些说明 启动类需要配置扫描包MapperScan @MapperScan(value = "pro.shushi", annotationClass = Mapper.class) @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, FreeMarkerAutoConfiguration.class}) public class DemoApplication { 调用Mapper接口的时候，需要指定数据源；即上述示例代码中的 DsHintApi dsHint = DsHintApi.model(DemoItem.MODEL_MODEL)， 实际代码中使用 try-with-resources语法。 从Mapper返回的结果中获取数据 如果SQL Mapper中已定义了resultMap，调用Mapper(DAO)返回的就是Java对象 如果Mapper返回的是Map<String, Object>，则通过 DataConverter.out进行转化，参考上面的示例 其他参考：Oinone连接外部数据源方案：https://doc.oinone.top/backend/4562.html
