<!-- spring 包扫描 -->

4. xxx-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>
<!-- Bean头部 -->
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd">

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
<value>/WEB-INF/jsp/</value>
</property>
<property name="suffix">

</property>
</bean>
</beans>
至此，这个项目的配置文件就告一段落
5. Controller
package com.bank.base.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.bank.base.entity.User;
import com.bank.base.service.BaseService;
@Controller
@RequestMapping(value = "bank")
public class BaseController {
@Autowired
private BaseService baseService;
@RequestMapping(value = "success")
@ResponseBody
public String success() {
System.out.println("im here");
return "success";
}
@RequestMapping(value = "reg")
@ResponseBody
public String reg(User user) {
baseService.register(user);
return "ok";
}
@RequestMapping(value = "find")
@ResponseBody
public User findUser(int id){
return baseService.findUserById(id);
}
@RequestMapping(value = "del")
@ResponseBody
public String delete(int id){
baseService.delete(id);
return "success";
}
}
7. Service
package com.bank.base.service;
import javax.transaction.Transactional;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.bank.base.dao.BaseDao;
import com.bank.base.entity.User;
@Service
public class BaseService {
@Autowired
private BaseDao baseDao;
@Transactional
public void register(User user){
baseDao.add(user);
}
public User findUserById(int id){
return baseDao.get(id);
}
@Transactional
public void delete(int id){
baseDao.delete(id);
}
}
8. Dao
package com.bank.base.dao;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.orm.hibernate5.HibernateTemplate;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import com.bank.base.entity.User;
@Repository
public class BaseDao {
@Autowired
private SessionFactory sessionFactory;
@Autowired
private HibernateTemplate hibernateTemplate;
@Transactional
public void add(User user) {
this.hibernateTemplate.save(user);
}
public User get(int id) {
return getSession().get(User.class, id);
}
private Session getSession() {
return sessionFactory.getCurrentSession();
}
@Transactional
public void delete(int id) {
Session session = getSession();
User user = get(id);
session.delete(user);
}
}
亲测成功!
后续会搭建项目中遇到的一些问题在做深入的了解。
