SpringBoot集成MyBatis以及配置事务，xml也打进war包，tomcat部署war

目录：

1、SpringBoot集成MyBatis
2、SpringBoot配置事务
3、demo
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。

3、demo    <--返回目录

3.1、项目结构    <--返回目录

3.2、代码    <--返回目录

　　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);
    }

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
