java - 创建实体管理器时映射用户角色

Question

Map properties = new HashMap();
properties.put("javax.persistence.jdbc.driver", "org.firebirdsql.jdbc.FBDriver");
properties.put("javax.persistence.jdbc.url", "jdbc:firebirdsql://localhost:3050/" + DBpath);
properties.put("javax.persistence.jdbc.user", "dbuser");
properties.put("javax.persistence.jdbc.password","dbpassword");
Persistence.createEntityManagerFactory("DB_manager", properties);
DB_ondulatiPUEntityManager = Persistence.createEntityManagerFactory("DB_manager",properties).createEntityManager();

我可以正确创建实体管理器，问题是我使用的用户已在数据库中授予特定角色，我如何在属性中指定此角色？否则我会得到错误 “无权读取/选择访问表...”

Answer 1

您可以将它们添加到 URL，就像直接通过 DriverManager 创建连接一样:

properties.put("javax.persistence.jdbc.url", 
   "jdbc:firebirdsql://localhost:3050/" + DBpath + "?roleName=myrole");
