springboot maven资源路径配置 resource路径配置, 解决mybatis的xml放在java路径而没有放在resource路径下报错的问题

 

 

 

 

 

 

我是这样配置的

 

 

      
      
         
            src/main/java
         
         
            src/main/resources
         
      
      
         
            org.springframework.boot
            spring-boot-maven-plugin
         
         
         
            org.apache.maven.plugins
            maven-surefire-plugin
            
               true
            
         
      
   

 

 

然后在资源文件 application.properites里面配置mybatis的xml路径

 

 

server.port=8081

#必须有
mybatis.mapper-locations=classpath*:com/hanhan/dao/xmlMapper/*.xml
#必须有
logging.config=classpath:logback.xml
#必须有
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
#必须有
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
#必须有
spring.datasource.username=root
#必须用
spring.datasource.password=root


#32位随机字符串
#dd9008e5ec8608c9eb9d57ab764651eb
rand.str = ${random.value}
#36位,比32位的多了4个-
#0cf88531-9569-44c4-926e-2528dd5948e2
rand.uuid = ${random.uuid}
#随机int类型,主意有负数
rand.intid = ${random.int}
#随机long类型
rand.longid = ${random.long}
#100以内的随机int类型
rand.number = ${random.int(100)}
#0-10亿范围内的随机int类型
rand.range = ${random.int[0,1000000000]}

java的接口mapper路径扫描在启动类上配置 

 

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);
   }
}
