3.1、项目结构
3.2、代码
3.3、本地启动
3.4、打成war部署到tomcat
1、SpringBoot集成MyBatis <--返回目录
另外可以参考:Spring Security(一)自定义表单及认证授权(整合mybatis generator和mybatis)
2、SpringBoot配置事务 <--返回目录
@Transactional既可以使用在方法上,也可以使用在类上。

ServletInitializer:作用打war包
public class ServletInitializer extends SpringBootServletInitializer { @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(Application.class); } }
主启动类 Application, @MapperScan("com.oy.dao") 扫描生成dao的实现
@SpringBootApplication @MapperScan("com.oy.dao") public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
PageController
@Controller public class PageController { @GetMapping({"/", "/index"}) public String toIndex() { return "index"; } @GetMapping("/page/{pageName}") public String toPage(@PathVariable String pageName) { return pageName; } }
BookController
/** * @author oy * @version 1.0 * @date 2019年1月9日 * @time 下午7:32:15 */ @Controller @RequestMapping("/book") public class BookController { @Autowired private BookService bookService; /** * 查询所有图书 * @return */ @RequestMapping("/list") public ModelAndView list() { ModelAndView mv = new ModelAndView(); mv.addObject("bookList", bookService.list()); mv.setViewName("book/list"); return mv; } }
BookServiceImpl
@Service public class BookServiceImpl implements BookService { @Autowired private BookDao bookDao; @Override public List<Book> list() { return bookDao.findAll(); } }
BookDao
public interface BookDao { List<Book> findAll(); }

3.3、本地启动 <--返回目录
选中Application,右键
访问:http://localhost/book/list
3.4、打成war部署到tomcat <--返回目录
选中项目,Run as -> Maven build...
将打成的war,改名为ROOT.war(改名为ROOT访问时就无需加项目名),复制到tomcat的webapps目录下
双击 bin/startup.bat, 启动tomcat。查看ROOT.war解压后的目录结构
