我是這樣配置的

<build>
      <!--resources配置解決mybatis 的mapperXml配置在java路徑不被掃描的問題 -->
      <resources>
         <resource>
            <directory>src/main/java</directory>
         </resource>
         <resource>
            <directory>src/main/resources</directory>
         </resource>
      </resources>
      <plugins>
         <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
         </plugin>
         <!--跳過測試 -->
         <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
               <skipTests>true</skipTests>
            </configuration>
         </plugin>
      </plugins>
   </build>


</project>
 

然後在資原始檔 application.properites裡面配置mybatis的xml路徑

server.port=8081

#必須有
mybatis.mapper-locations=classpath*:com/hanhan/dao/xmlMapper/*.xml
#必須有
logging.config=classpath:logback.xml
#必須有
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
#必須有
spring.datasource.url=jdbc:mysql://127.0.0.1:3307/ipace?autoReconnect=true&useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=CONVERT_TO_NULL&useSSL=false&serverTimezone=CTT
#必須有
spring.datasource.username=root
#必須用
spring.datasource.password=root


#32位隨機字串
#dd9008e5ec8608c9eb9d57ab764651eb
rand.str = ${random.value}
#36位,比32位的多了4個-
#0cf88531-9569-44c4-926e-2528dd5948e2
rand.uuid = ${random.uuid}
#隨機int型別,主意有負數
rand.intid = ${random.int}
#隨機long型別
rand.longid = ${random.long}
#100以內的隨機int型別
rand.number = ${random.int(100)}
#0-10億範圍內的隨機int型別
rand.range = ${random.int[0,1000000000]}

 

java的介面mapper路徑掃描在啟動類上配置 

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication(scanBasePackages = {"com.hanhan","hanhan"})
@MapperScan({"com.hanhan.dao"})
@EnableScheduling
public class BeetltestApplication {


   public static void main(String[] args) {
      SpringApplication.run(BeetltestApplication.class, args);
   }
}
