无法基于RequestMapping值访问View

RegistrationService

package com.simple.services;

import com.simple.dao.RegistrationDAO;

import simple.Registration;

public class RegistrationService {

public int insert(Registration r){
    RegistrationDAO rdao = new RegistrationDAO();
    return rdao.insert(r);

}

}

RegistrationDAO

package com.simple.dao;



import java.sql.Types;

import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.stereotype.Component;

import simple.Registration;
