续写于SSM整合-Spring整合MyBatis 02
一、
1、配分页插件

2、配事务jdbc类型的事务
2.1、开启事务驱动

2.2、注入jdbc类型的事务

目前在applicationContext.xml的配置

2.3、在UserService业务接口添加事务的注解，注意增删改不能设为只读

import org.springframework.transaction.annotation.Transactional;

@Transactional(readOnly = true)
public interface UserService {
    /**
     * 保存用户信息
     * @param user
     * @return
     */
    @Transactional(readOnly = false)
    public boolean save(User user);

    /**
     * 删除用户信息
     * @param uuid
     * @return
     */
    @Transactional(readOnly = false)
    public boolean delete(Integer uuid);

    /**
     * 修改用户信息
     * @param user
     * @return
     */
    @Transactional(readOnly = false)
    public boolean update(User user);

    /**
     * 查询用户信息
     * @param uuid
     * @return
     */
    public User get(Integer uuid);

    /**
     * 分页查询用户信息
     * @param page
     * @param size
     * @return
     */
   public PageInfo<User> getAll(int page, int size);

    /**
     * 用户的登录
     * @param userName
     * @param password
     * @return
     */
    public User login(String userName,String password);
}
