使用MyBatis Generator生成dao接口、映射文件和实体类 如何生成

搭建过程：

先来看一下项目的 目录结构

1.配置dispatcherServlet-servlet.xml，将此文件放于WEB-INF下

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">

2.配置web.xml

http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

login.jsp

dispatcherServlet

org.springframework.web.servlet.DispatcherServlet

1

dispatcherServlet

/

default

*.css

default

*.gif

default

*.jpg

default

*.js

characterEncodingFilter

org.springframework.web.filter.CharacterEncodingFilter

encoding

UTF-8

forceEncoding

true

characterEncodingFilter

/*

contextConfigLocation

classpath:applicationContext.xml

org.springframework.web.context.ContextLoaderListener

3.配置applicationContext.xml，并 将自动生成的dao实现类交给Spring管理

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.1.xsd

http://www.springframework.org/schema/aop

http://www.springframework.org/schema/aop/spring-aop-3.1.xsd">

4.将service实现类交给Spring管理

@Service("userService")public class UserServiceImpl implementsIUserService {

@Autowired　　// 此处使用ByType自动装配 dao实现类privateUserEntityMapper userDao;

@OverridepublicUserEntity login(UserEntity user) {returnuserDao.getByNameAndPwd(user);

}@Override

@Transactional　　// 使用该注解实现事务管理public voiddelById(String id) {

userDao.delByid(id);

}}

5.创建Controller

@Controller

@RequestMapping(value="/emp")public classEmpController {

@Autowired　　// 使用ByType装配privateIEmpService empService;@RequestMapping(value="/queryEmps")publicString queryEmps(HttpServletRequest request){

List list =empService.queryAll();request.getSession().setAttribute("list",list );return "index.jsp";

}

6.现在就可以使用 http://localhost:8080/ProjectName/emp/queryEmps访问到上述Controller
