  如何自定义覆盖内置模块的页面

  1.首先通过sql查询找到我们需要的页面，从其中的template字段复制出原视图的配置 通过模型编码model在base_view查找需要修改的视图 select * from base_view where model='workflow.WorkflowUserTask' and is_deleted = 0; 2.将base_view的template内容复制到java的core工程的resources目录下新建一个xml文件，修改里面的动作名称 <view widget="WorkFlowImplement"> <template slot="actions"> <action name="$$internal_GotoListTableRouter" priority="1" model="workflow.WorkflowUserTask" tag="contextFreeAction"/> <action name="approveStaging" widget="FlowTaskCommonAction" invisible="!(activeRecord.allowStaging)" priority="2" label="新暂存" model="workflow.WorkflowUserTask" displayName="新暂存"/> <action name="workflow_agree" invisible="!(activeRecord.allowAgree && activeRecord.status == &apos;ACTIVE&apos;)" priority="3" label="新同意" model="workflow.WorkflowUserTask" load="fetchDetailReadOnly" displayName="新同意" goBack="true" validateForm="true" loadRootData="true"/> <action name="workflow_rejust" invisible="!(activeRecord.allowReject && activeRecord.status == &apos;ACTIVE&apos;)" priority="4" label="新拒绝" model="workflow.WorkflowUserTask" displayName="新拒绝" goBack="true" loadRootData="true" tag="contextFreeAction"/> <action name="workflow_turnon" invisible="!(activeRecord.taskType == &apos;APPROVE&apos; && activeRecord.allowTransfer && activeRecord.status == &apos;ACTIVE&apos;)" priority="5" label="新转交" model="workflow.WorkflowUserTask" load="fetchDetailReadOnly" displayName="新转交" goBack="true" loadRootData="true" tag="contextFreeAction"/> <action name="workflow_addsign" invisible="!(activeRecord.taskType == &apos;APPROVE&apos; && activeRecord.allowAddSign && activeRecord.status == &apos;ACTIVE&apos;)" priority="6" label="新加签" model="workflow.WorkflowUserTask" load="fetchDetailReadOnly" displayName="新加签" goBack="true" loadRootData="true" tag="contextFreeAction"/> <action name="workflow_write_fallback" invisible="!(activeRecord.taskType == &apos;WRITE&apos; && activeRecord.allowFallback && activeRecord.status == &apos;ACTIVE&apos;)" priority="7" label="新回退" model="workflow.WorkflowUserTask" displayName="新回退" goBack="true" loadRootData="true" tag="contextFreeAction"/> <action name="workflow_sharing" priority="8" label="新分享" model="workflow.WorkflowUserTask" displayName="新分享" goBack="true" loadRootData="true" tag="contextFreeAction"/> </template> <template slot="fields"> <field name="remark" widget="TextArea" invisible="activeRecord.taskType != &apos;APPROVE&apos;" priority="8" model="workflow.WorkflowUserTask" data="remark" displayName="意见备注"/> </template> </view> 3.在生命周期的元数据编辑方法内覆盖视图 package pro.shushi.pamirs.demo.core.init; import org.springframework.core.Ordered; import org.springframework.core.annotation.Order; import org.springframework.stereotype.Component; import pro.shushi.pamirs.boot.common.api.command.AppLifecycleCommand; import pro.shushi.pamirs.boot.common.extend.MetaDataEditor; import pro.shushi.pamirs.core.common.InitializationUtil; import pro.shushi.pamirs.demo.api.DemoModule; import pro.shushi.pamirs.meta.annotation.fun.extern.Slf4j; import pro.shushi.pamirs.meta.api.dto.meta.Meta; import pro.shushi.pamirs.meta.enmu.ViewTypeEnum; import pro.shushi.pamirs.workflow.app.api.model.WorkflowUserTask; import java.util.Map; @Slf4j @Component @Order(Ordered.LOWEST_PRECEDENCE) public class DemoModuleMetaInstall implements MetaDataEditor { @Override public void edit(AppLifecycleCommand command,…

  Oinone请求路由源码分析

  通过源码分析，从页面发起请求，如果通过graphQL传输到具体action的链路，并且在这之间做了哪些隐式处理分析源码版本5.1.x 请求流程大致如下： 拦截所有指定的请求 组装成graphQL请求信息 调用graphQL执行 通过hook拦截先执行 RsqlDecodeHook：rsql解密 UserHook： 获取用户信息, 通过cookies获取用户ID，再查表获取用户信息，放到本地Local线程里 RoleHook： 角色Hook FunctionPermissionHook： 函数权限Hook ,跳过权限拦截的实现放在这一层，对应的配置 pamirs: auth: fun-filter: – namespace: user.PamirsUserTransient fun: login #登录 – namespace: top.PetShop fun: action DataPermissionHook： 数据权限hook PlaceHolderHook：占位符转化替换hook RsqlParseHook： 解释Rsql hook SingletonModelUpdateHookBefore 执行post具体内容 通过hook拦截后执行 QueryPageHook4TreeAfter： 树形Parent查询优化 FieldPermissionHook： 字段权限Hook UserQueryPageHookAfter UserQueryOneHookAfter 封装执行结果信息返回 时序图 核心源码解析 拦截所有指定的请求 /pamirs/模块名RequestController @RequestMapping( value = "/pamirs/{moduleName:^[a-zA-Z][a-zA-Z0-9_]+[a-zA-Z0-9]$}", method = RequestMethod.POST ) public String pamirsPost(@PathVariable("moduleName") String moduleName, @RequestBody PamirsClientRequestParam gql, HttpServletRequest request, HttpServletResponse response) { } DefaultRequestExecutor 构建graph请求信息，并调用graph请求 () -> execute(GraphQL::execute, param), param private <T> T execute(BiFunction<GraphQL, ExecutionInput, T> executor, PamirsRequestParam param) { // 获取GraphQL请求信息，包含grapsh schema GraphQL graphQL = buildGraphQL(param); … ExecutionInput executionInput = ExecutionInput.newExecutionInput() .query(param.getQuery()) .variables(param.getVariables().getVariables()) .dataLoaderRegistry(Spider.getDefaultExtension(DataLoaderRegistryApi.class).dataLoader()) .build(); … // 调用 GraphQL的方法execute 执行 T result = executor.apply(graphQL, executionInput); … return result; } QueryAndMutationBinder 绑定graphQL读取写入操作 public static DataFetcher<?> dataFetcher(Function function, ModelConfig modelConfig) { if (isAsync()) { if (FunctionTypeEnum.QUERY.in(function.getType())) { return AsyncDataFetcher.async(dataFetchingEnvironment -> dataFetcherAction(function, modelConfig, dataFetchingEnvironment), ExecutorServiceApi.getExecutorService()); } else { return dataFetchingEnvironment -> dataFetcherAction(function, modelConfig, dataFetchingEnvironment); } } else { return dataFetchingEnvironment -> dataFetcherAction(function, modelConfig, dataFetchingEnvironment); } } private static Object dataFetcherAction(Function function, ModelConfig modelConfig, DataFetchingEnvironment environment) { try { SessionExtendUtils.tagMainRequest(); // 使用共享的请求和响应对象 return Spider.getDefaultExtension(ActionBinderApi.class) .action(modelConfig,…
