我已經使用Apache Olingo在我試圖獲取從MySQL數據庫的數據開發的Java項目，但我收到以下錯誤JDBC連接器的Apache Olingo
有一個例外！ com.mysql.jdbc.Driver
要在Apache olingo中爲此導入哪個庫。下面是我的Java類
private EntityCollection getData(EdmEntitySet edmEntitySet){
EntityCollection productsCollection = new EntityCollection();
// check for which EdmEntitySet the data is requested
if(DemoEdmProvider.ES_PRODUCTS_NAME.equals(edmEntitySet.getName())) {
List<org.apache.olingo.commons.api.data.Entity> productList = productsCollection.getEntities();
try
{
// create our mysql database connection
//String myDriver = "org.gjt.mm.mysql.Driver";
String myDriver ="com.mysql.jdbc.Driver";
String myUrl = "jdbc:mysql://localhost:3306/testDB";
Class.forName(myDriver);
Connection conn = DriverManager.getConnection(myUrl, "root", "test1234");
// our SQL SELECT query.
// if you only need a few columns, specify them by name instead of using "*"
String query = "SELECT * FROM Employee";
// create the java statement
Statement st = conn.createStatement();
// execute the query, and get a java resultset
ResultSet rs = st.executeQuery(query);
// iterate through the java resultset
while (rs.next())
{
String NAME = rs.getString("NAME");
String CITY = rs.getString("CITY");
int AGE = rs.getInt("AGE");
// print the results
final Entity e1 = new Entity()
.addProperty(new Property(null, "NAME", ValueType.PRIMITIVE, NAME))
.addProperty(new Property(null, "CITY", ValueType.PRIMITIVE, CITY))
.addProperty(new Property(null, "AGE", ValueType.PRIMITIVE,
AGE));
e1.setId(createId("Products", 1));
productList.add(e1);
}
st.close();
}
catch (Exception e)
{
System.err.println("Got an exception! ");
System.err.println(e.getMessage());
}
}
