一、背景

目前我們已經(jīng)修改完成了modeler單獨(dú)編譯，現(xiàn)在我們需要去除modeler的相關(guān)認(rèn)證，并且自動使用超級用戶來完成modeler的用戶查詢

二、代碼修改，去除認(rèn)證

2.1. 修改攔截請求

修改文件:SecurityConfiguration.java,讓spring security不攔截請求，修改后代碼:

核心修改為:
http.antMatcher("/api/**").authorizeRequests().antMatchers("/api/**").permitAll();

2.2. 修改用戶查詢信息

核心文件為SecurityUtils.java,核心修改內(nèi)容如下:

/*** @return the {@link User} object associated with the current logged in user.*/public static User getCurrentUserObject() {if (assumeUser != null) {return assumeUser;}RemoteUser user = new RemoteUser(); // FlowableAppUser appUser = getCurrentFlowableAppUser(); // if (appUser != null) { // user = appUser.getUserObject(); // }user.setId("admin");user.setDisplayName("admin");user.setFirstName("admin");user.setLastName("admin");user.setEmail("admin@admin.com");user.setPassword("test");List<String> pris = new ArrayList<>();pris.add(DefaultPrivileges.ACCESS_MODELER);pris.add(DefaultPrivileges.ACCESS_IDM);pris.add(DefaultPrivileges.ACCESS_ADMIN);pris.add(DefaultPrivileges.ACCESS_TASK);pris.add(DefaultPrivileges.ACCESS_REST_API);user.setPrivileges(pris);return user;}

2.3. 賬號查詢請求修改

如下,文件為RemoteAccountResource.java：

/*** GET /rest/account -> get the current user.*/@RequestMapping(value = "/rest/account", method = RequestMethod.GET, produces = "application/json")public UserRepresentation getAccount() {UserRepresentation userRepresentation = new UserRepresentation();userRepresentation.setFirstName("admin");userRepresentation.setLastName("admin");userRepresentation.setFullName("admin");userRepresentation.setId("admin");List<String> pris = new ArrayList<>();pris.add(DefaultPrivileges.ACCESS_MODELER);pris.add(DefaultPrivileges.ACCESS_IDM);pris.add(DefaultPrivileges.ACCESS_ADMIN);pris.add(DefaultPrivileges.ACCESS_TASK);pris.add(DefaultPrivileges.ACCESS_REST_API);userRepresentation.setPrivileges(pris); // UserRepresentation userRepresentation = null; // String currentUserId = SecurityUtils.getCurrentUserId(); // if (currentUserId != null) { // RemoteUser remoteUser = remoteIdmService.getUser(currentUserId); // if (remoteUser != null) { // userRepresentation = new UserRepresentation(remoteUser); // // if (remoteUser.getGroups() != null && remoteUser.getGroups().size() > 0) { // List<GroupRepresentation> groups = new ArrayList<>(); // for (RemoteGroup remoteGroup : remoteUser.getGroups()) { // groups.add(new GroupRepresentation(remoteGroup)); // } // userRepresentation.setGroups(groups); // } // // if (remoteUser.getPrivileges() != null && remoteUser.getPrivileges().size() > 0) { // userRepresentation.setPrivileges(remoteUser.getPrivileges()); // } // // } // }if (userRepresentation != null) {return userRepresentation;} else {throw new NotFoundException();}}

2.4. 效果驗(yàn)證

通過類FlowableModelerApplication啟動，啟動后效果如下:

2.5. 登錄驗(yàn)證

進(jìn)入登錄頁面http://localhost:8889/flowable-modeler,沒有認(rèn)證直接可以進(jìn)來

三、集成設(shè)計(jì)

將modeler作為一個(gè)單獨(dú)的微服務(wù)存在，可以獨(dú)立db，也可以公用db，如果獨(dú)立db，那么將流程導(dǎo)出，在自己的框架中導(dǎo)入，公用db，配置個(gè)流程查詢頁面即可，代碼到這個(gè)地步基本隨便集成了，后續(xù)我們深入研究如何是用流程的一些API，并盡量設(shè)計(jì)一個(gè)通用的服務(wù)，敬請期待。
