使用jdbc插入嵌入式映射的问题

Question

当我尝试使用jdbc插入嵌入式地图时会弹出以下异常

com.orientechnologies.orient.core.exception.OValidationException: impossible to convert value of field "permission"

引起：java.lang.ClassCastException：java.lang.String无法强制转换为java.util.Map     在com.orientechnologies.orient.core.record.impl.ODocument.autoConvertValues（ODocument.java:2256）     ......还有16个

这里有什么问题

更新 代码：

Map<String,Object> permission = new HashMap<>();
permission.put("user_permission",Byte.valueOf("15"));
new JdbcTemplate(datasource).update("Insert into Role SET name = ?, permission = ?","Role1",permission);

注意： 我正在使用spring jdbc

Answer 1

我尝试使用以下代码

Properties info = new Properties();
info.put("user", "root");
info.put("password", "root");

Connection conn = (OrientJdbcConnection) DriverManager.getConnection("jdbc:orient:remote:localhost/test", info);

Statement statement = conn.createStatement();

Map<String,Object> permission = new HashMap<String,Object>();
permission.put("user_permission",Byte.valueOf("15"));

Gson gson = new Gson();
String myString = gson.toJson(permission);

String query= "Insert into ORole SET name = 'Role1' , permission = " + myString;

statement.execute(query);

希望它有所帮助。
