Question

I am trying to send multiple parameter to Mapper function defined in DAO implementation but unable to send more than 1 parameter in the case when parameter are not holder of any class.
I mean how can I modify the following code-

obj.getName(int a, int b);

In DAO implementation

public void getAllName() throws PersistenceException {
        SqlSession session = sf.openSession();
        try {
            session.selectList("getNames");         
        } finally {
            session.close();
        }
    }

I want to send a and b to query getNames.

Thanks in advance.

If you are using DAO implementation then you can do this by using a HashMap. Just add the key-value pair in HashMap and add it in function call and you can access it in the mapper.xml using “key”.
