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.jar

3.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

	4.0.0

	yiyang
	war

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

## shujuku
spring.datasource.url=jdbc:mysql://localhost:3306/yiyang
spring.datasource.username=yang
spring.datasource.password=yang
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

spring.jpa.properties.hibernate.hbm2ddl.auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.show-sql= true

spring:
  thymeleaf:
    encoding: UTF-8
    mode: HTML5
    prefix: classpath:/templates/
    suffix: .html
    check-template: true
    cache: false
    
mybatis.typeAliasesPackage=com.miliyf.fan.entity
mybatis.mapperLocations=classpath:/mybatis/mapper/*.xml

# 
spring.mvc.view.prefix=/WEB-INF/jsp/

spring.mvc.view.suffix=.jsp

application.hello=Hello GOD

logging.path=/user/local/log
logging.level.com.favorites=DEBUG
logging.level.org.springframework.web=INFO
logging.level.org.hibernate=ERROR
logging.level.com.miliyf=debug
