package com.edu.ssh.service.impl;
import javax.annotation.Resource;
import org.springframework.stereotype.Component;
import com.edu.ssh.dao.UserDAO; import com.edu.ssh.model.User; import com.edu.ssh.service.UserManager;
// 用Component注解，使得本类交给spring容器管理， // 并且指定bean的名字为userManagerImpl @Component("userManagerImpl") public class UserManagerImpl implements UserManager {
private UserDAO userDAO;
public UserDAO getUserDAO() { return userDAO; }
// 使用spring依赖注入 @Resource public void setUserDAO(UserDAO userDAO) { this.userDAO = userDAO; }
public boolean exists(User user) { return userDAO.checkUserExistsWithName(user.getUsername()); }
public void insertOneUser(User user) { userDAO.save(user); } }

在SSH里spring主要的功能是管理几乎所有的bean，实例化程序所有配置好的bean。有了spring Hibernate的所有配置都移到了spring的配置文件里，但是struts2的配置文件还是要单独配置。spring主要是管理程序的事务管理，是使用AOP实现的。
