3 yml配置

3.1 修改前

mybatis:
#  type-aliases-package: com.wen.system
  mapper-locations: classpath:mapper/**/*.xml
  configuration:
    map-underscore-to-camel-case: true
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

3.2 修改后

mybatis:
#  type-aliases-package: com.wen.system
  mapper-locations: classpath*:mapper/**/*.xml
  configuration:
    map-underscore-to-camel-case: true
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

3.3 总结

        对于多模块项目应该在classpath后面加*
