Spring-整合mybatis

在后面的学习中我们会接触到maven，那个时候就不用我们自己这么费劲的导入jar包了

导入springIOC相关jar包、mybatis包、mybatis整个包和jdbc

    
    
        contextConfigLocation
        classpath:applicationcontext.xml
    
    
    
        org.springframework.web.context.ContextLoaderListener
    

public class LoginServlet extends HttpServlet {
    private UserService service;
    @Override
    public void init() throws ServletException {
        ApplicationContext ac = WebApplicationContextUtils.getWebApplicationContext(this.getServletContext());
        service = (UserServiceImpl) ac.getBean("userService");
    }

    @Override
    protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        String user = req.getParameter("user");
        String pwd = req.getParameter("pwd");

        User user1 = service.doLogin(user, pwd);
        if(user1!=null){
            resp.getWriter().print("success");
        }else{
            resp.getWriter().print("false");

        }
    }
}
