springboot学习随笔
1.使用配置
eclipse、jdk1.8、maven3.5.4、tomcat8、MySQL
2.新建maven web项目，容易出现新建不成功，缺少maven-archetype-webapp-1.0-alpha-4.jar之类的，百度搜索该jar包，保存之后，cmd管理员权限进入到该jar包保存路径下，执行以下命令（注：后边jar包名称为下载名称），如果该命令执行失败，检查maven、jdk配置是否完成，jdk和maven版本是否匹配，之后执行命令mvn clean;最后再执行以下命令，再去eclipse新建项目即可
mvn install:install-file -DgroupId=org.apache.maven.archetypes -DartifactId=maven-archetype-webapp -Dversion=1.0 -Dpackaging=jar -Dfile=maven-archetype-webapp-1.0-alpha-4.jar3.新建完毕之后应不会报错
修改pom文件，也可一个一个添加，在这我的pom文件做参考

新建YiyangApplication类该类一定要在controller层级之上，不然springboot会扫描不到
//Spring Boot 应用的标识
@SpringBootApplication
@ComponentScan("com.miliyf")
//@MapperScan("com.miliyf.fan.dao")
@EnableScheduling
public class YiyangApplication {
protected final static Logger logger = LoggerFactory.getLogger(YiyangApplication.class);
public static void main(String[] args) {
System.out.println("--------start--------");
SpringApplication.run(YiyangApplication.class, args);
logger.info("YiyangApplication is sussess!");
System.out.println("--------end--------");
}
}新建controller控制类（@RequestMapping可以不写，运行main方法也可以运行访问http://localhost:8080即可；写的话类名，方法名之上都要写，不然会访问不到）--至此可以main方法运行访问
@Controller
@RequestMapping("/yiyang")
public class SampleController {
@Autowired
private userService userService;
@RequestMapping("/yang")
public String sayHello() {
System.out.println("------------------123");
return "index";
}
}4.部署到Tomcat上
新建ServletInitializer类extends SpringBootServletInitializer类，与YiyangApplication类同级别
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.annotation.Configuration;
@Configuration
public class ServletInitializer extends SpringBootServletInitializer{
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
// TODO Auto-generated method stub
System.out.println("======================start==========================");
return builder.sources(YiyangApplication.class);
}
}5,使用eclipse打成war包，将war包复制到tomcat的webapp下，启动bin目录下的startup.bat--至此访问http://localhost:8080/yiyang/yang
6.记得在resources下新建文件templates/index.html;application.properties
该文件内容作参考
