初學springboot、springMVC、Mybatis專案--學習筆記

1.建立sts專案 建立步驟連結:https://blog.csdn.net/he90227/article/details/53308222 (我在建立專案時,選擇了mysql,但是初始測試時,未配置資料庫連結,專案啟動報錯:Failed to configure a DataSource: ‘url’ attribute is not specified and no embedde,解決方法如圖:
注意:在使用Autowired自動注入時,需要將紅色框體中的內容刪除,否則報錯,Property ‘sqlSessionFactory’ or ‘sqlSessionTemplate’ are required
建立config包及Application檔案:
package com.fengsx; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Import; import com.fengsx.config.ApplicationConfig; /** * Configuration配置spring並啟動spring容器 * Import--ApplicationConfig應用配置類 * @author xi * */ @Configuration @SpringBootApplication @Import({ApplicationConfig.class}) public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
ApplicationConfig檔案:
package com.fengsx.config; import org.mybatis.spring.annotation.MapperScan; import org.springframework.context.annotation.ComponentScan; /** * 應用配置類 * MapperScan(掃描mapper檔案) * ComponentScan告訴Spring 哪個packages 的用註解標識的類 會被spring自動掃描並且裝入bean容器 * 例如,如果你有個類用@Controller註解標識了,那麼,如果不加上@ComponentScan,自動掃描該controller, * 那麼該Controller就不會被spring掃描到,更不會裝入spring容器中,因此你配置的這個Controller也沒有意義。 * 微服務 通過EnableFeignClients呼叫其他服務的api(這裡未使用) * @author xi * */ @MapperScan("com.fengsx.domain.persistence") @ComponentScan({"com.fengsx.api.controller", "com.fengsx.domain.service"}) public class ApplicationConfig { }
5.pom.xml配置如下:

6.application.properties簡單配置如下:
# --- {Logging}
#logging.level.DEBUG
logging.level.org.springframework.web=INFO
logging.level.com.netflix.discovery=DEBUG
logging.level.org.hibernate=ERROR
logging.level.org.springframework.boot.autoconfigure.security=WARN
logging.level.com.fengsx.domain.persistence=DEBUG
# --- {MyBatis}
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/cf_couture?characterEncoding=UTF-8&useSSL=false
spring.datasource.username=root
spring.datasource.password=123
mybatis.type-aliases-package=com.fengsx.domain
7.generatorConfig.xml自動生成modal、mapper.java、mapper.xml
