問題與embeddedmap使用JDBC

Question

插入，當我試圖插入使用JDBC的embeddedmap以下異常彈出

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

at com.orientechnologies.orient.core.record.impl.ODocument.autoConvertValues(ODocument.java:2270)

產生的原因：java.lang.ClassCastException：java.lang.String中不能轉換爲Java。 util.Map 在com.orientechnologies.orient.core.record.impl.ODocument.autoConvertValues（ODocument.java:2256） ...... 16多個

什麼是這裏的問題

UPDATE CODE：

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： 我使用了Spring JDBC

Answer 1

我已經用下面的代碼

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); 

嘗試

希望它有幫助。
