控制器是：
package com.project.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import com.project.model.User;
import com.project.service.UserService;
@RestController
@RequestMapping("/testmap")
public class TestController {
@Autowired
private UserService userService;
@RequestMapping(value="/test", method = RequestMethod.GET, produces = "application/json")
public @ResponseBody List<User> testMethod(){
try{
System.out.println("--------------inside testmethod----------------------------");
return userService.getAllUser();
}catch(Exception e){
System.out.println("Exception Occur = "+e);
return null;
}
}
}
服务看起来像：
package com.project.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import com.project.dao.UserDAO;
import com.project.model.User;
@Service
@Configuration
@EnableWebMvc
public class UserService {
@Autowired
private UserDAO userDAO;
@Transactional(readOnly = true)
public List<User> getAllUser() {
return userDAO.fetchAll(User.class);
}
}
DAO看起来像：
package com.project.dao;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import com.project.common.HibernateUtil;
@Repository
@Configuration
@EnableWebMvc
public class UserDAO extends HibernateUtil {
}
通用DAO是：
package com.project.common;
import java.io.Serializable;
import java.util.List;
import org.hibernate.Criteria;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Repository;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
@Repository
@Configuration
@EnableWebMvc
public class HibernateUtil {
@Autowired
private SessionFactory sessionFactory;
public <T> Serializable create(final T entity) {
return sessionFactory.getCurrentSession().save(entity);
}
public <T> T update(final T entity) {
sessionFactory.getCurrentSession().update(entity);
return entity;
}
public <T> void delete(final T entity) {
sessionFactory.getCurrentSession().delete(entity);
}
public <T> void delete(Serializable id, Class<T> entityClass) {
T entity = fetchById(id, entityClass);
delete(entity);
}
public <T> void saveOrUpdate(final T o){
sessionFactory.getCurrentSession().saveOrUpdate(o);
}
public <T> List<T> getAll(final Class<T> type) {
final Criteria crit = sessionFactory.getCurrentSession().createCriteria(type);
return crit.list();
}
@SuppressWarnings("unchecked")
public <T> List<T> fetchAll(Class<T> entityClass) {
return sessionFactory.getCurrentSession().createQuery(" FROM "+entityClass.getName()).list();
}
@SuppressWarnings("rawtypes")
public <T> List fetchAll(String query) {
return sessionFactory.getCurrentSession().createSQLQuery(query).list();
}
@SuppressWarnings("unchecked")
public <T> T fetchById(Serializable id, Class<T> entityClass) {
return (T)sessionFactory.getCurrentSession().get(entityClass, id);
}
}
web.xml是：

我的项目配置在上面。实际上问题是找不到“http://localhost:8080/ShoppingProject/testmap/test”的映射和警告在
之下2017-06-24 13:19:39 DEBUG DispatcherServlet:865 - DispatcherServlet with name 'mvc-dispatcher' processing GET request for [/ShoppingProject/testmap/test]

我遇到了映射中的问题？任何帮助将不胜感激
