org.springframework.dao.InvalidDataAccessApiUsageException：SQLパラメータの値がありません

Question

私はJDBC JDBCの例で作業しています。BeanPropertySqlParameterSourceとSqlParameterSourceを使用しています。コードを実行すると、次のエラーが表示されていることがわかります。数時間過ごした後、私はその解決策を見つけられません。ここで何が間違っているか教えてください。

org.springframework.dao.InvalidDataAccessApiUsageException: No value supplied for the SQL parameter 'employeeId': Invalid property 'employeeId' of bean class [com.spring.jdbc.model.Order]: Bean property 'employeeId' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?

Answer 1

ああ、私は問題を参照してください。問題はクエリであり、変数名はまったく一致しません。以下のクエリを使用してください。完了！あなたがshipperIDとemployeeIDなくshipperIdとemployeeId

を使用する必要があります

String sql = "SELECT count(*) FROM orders WHERE EmployeeID = :employeeID AND 
ShipperID = :shipperID ";
