SSH系列（二）：Spring + Hibernate + SpringMVC Maven整合
阿新 • • 發佈：2019-01-08
宣告：本文是關於Spring4.3.2 + Hibernate5.1.0 + SpringMVC Maven方式的簡單整合。pom.xml只添加了最基本的依賴，實際開發中需要的依賴根據專案具體新增; 本文不詳細說明maven安裝與使用。不當的地方歡迎大家指正，不勝感激。
整合環境
JDK 1.7
Tomcat：apache-tomcat-7.0.59
Spring：spring-framework-4.3.2.RELEASE
Hibernate：hibernate-release-5.1.0.Final
Maven工程目錄結構
整合步驟
MyEclipse中建立Maven工程
File –> New –> Project：
Next：
選擇建立原型：
指定原型引數：groupId、ArtifactID 和 version 等
注意：此時建立好工程中目錄如下圖，需要自己新增src/main/java、src/test/resource、src/test/java等目錄
pom.xml中新增依賴

@Service
public class UserServiceImpl implements IUserService {
@Autowired
private IUserDao userDao;
@Override
@Transactional(readOnly = true)
public List<User> findAllUser() {
return userDao.findAllUser();
}
