java如何在Liferay portlet中使用Bonite引擎api？

Question

我安装了BonitaBPMCommunity-7.2.3和liferay-portal-6.2-ce-ga6

• 博尼塔-http://localhost:28604/bonita
• Liferay-http://localhost:8080

我想在Liferay portlet中使用Bonita引擎Api。我已经在目录"C:\_portal\liferay-portal-6.2-ce-ga6\bonita"中配置了bonita home

我的java代码：

System.setProperty(BONITA_HOME_KEY, BONITAHOME);
System.out.println("Start");
final LoginAPI loginAPI = TenantAPIAccessor.getLoginAPI();
System.out.println("login with install//install");
final APISession session = loginAPI.login("walter.bates", "bpm");
final IdentityAPI identityAPI = TenantAPIAccessor.getIdentityAPI(session);
final SearchResult<User> searchUsers = identityAPI.searchUsers(new SearchOptionsBuilder(0, 20).done());
System.out.println("20 first users:");
for (final User user : searchUsers.getResult()) {
  System.out.println(" * " + user.getUserName() + " -- " + user.getId());
  }
loginAPI.logout(session);
System.out.println("logged out");  
System.out.println("Hello");

我有一个错误：

Answer 1

1. 我从bonita服务器的URL和用于登录的用户中收集到，您正试图连接到studio中的嵌入式服务器进行测试。请注意，您为测试bonita和liferay而进行的唯一可靠测试是一台独立的bonita服务器（您可以在liferay服务器中安装bonita，但由于两者都可能占用大量内存，我不建议这样做）
2. 唯一需要设置bonita Home的时间是在您最喜欢的IDE服务器配置或直接在服务器配置中的setenv变量中

3. 除了登录部分，你的代码还可以。缺少tenantApiAcessor参数的配置（下面的示例代码）

   映射设置=新建HashMap（）； 设置。put（“server.url”，“http://localhost:8080”）； 设置。put（“application.name”、“bonita”）； 我是打字机管理员。SetApitype和Params（ApiAccessType.HTTP，设置）； //使用租户访问器获取LoginAPI LoginAPI LoginAPI=租户访问器。getLoginAPI（）； //此处的异常处理
