From a8250500fc56916bb3a4d640e45152900312a6f6 Mon Sep 17 00:00:00 2001 From: guqing <38999863+guqing@users.noreply.github.com> Date: Thu, 4 May 2023 15:40:38 +0800 Subject: [PATCH] refactor: add system initialization check and redirect to console if not initialized (#3892) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit #### What type of PR is this? /kind improvement /area core /milestone 2.5.2 #### What this PR does / why we need it: 添加系统初始化检查，如果未初始化则重定向到控制台。 此检查只针对首页，当用户访问首页时检查到未初始化则跳转到 Console 让用户初始化以优化没有数据时的访问体验。 SetupStateCache 用于缓存系统初始化状态，当数据库状态改变时会更新缓存以优化性能，避免每次访问首页都查询数据。 #### Which issue(s) this PR fixes: A part of #3230 #### Does this PR introduce a user-facing change? ```release-note 添加系统初始化检查，如果未初始化则重定向到控制台 ``` --- .../run/halo/app/infra/SetupStateCache.java | 96 +++++++++++++++ .../InitializeRedirectionWebFilter.java | 57 +++++++++ .../InitializeRedirectionWebFilterTest.java | 109 ++++++++++++++++++ .../ThemeMessageResolverIntegrationTest.java | 5 + 4 files changed, 267 insertions(+) create mode 100644 application/src/main/java/run/halo/app/infra/SetupStateCache.java create mode 100644 application/src/main/java/run/halo/app/security/InitializeRedirectionWebFilter.java create mode 100644 application/src/test/java/run/halo/app/security/InitializeRedirectionWebFilterTest.java diff --git a/application/src/main/java/run/halo/app/infra/SetupStateCache.java b/application/src/main/java/run/halo/app/infra/SetupStateCache.java new file mode 100644 index 0000000000..b989953433 --- /dev/null +++ b/application/src/main/java/run/halo/app/infra/SetupStateCache.java @@ -0,0 +1,96 @@ +package run.halo.app.infra; + +import io.micrometer.common.util.StringUtils; +import java.util.Optional; +import java.util.concurrent.atomic.AtomicBoolean; +import java.util.function.Supplier; +import lombok.Data; +import org.springframework.lang.NonNull; +import org.springframework.stereotype.Component; +import run.halo.app.extension.ConfigMap; +import run.halo.app.extension.ExtensionClient; +import run.halo.app.extension.controller.Controller; +import run.halo.app.extension.controller.ControllerBuilder; +import run.halo.app.extension.controller.Reconciler; +import run.halo.app.infra.utils.JsonUtils; + +/** + *
