springboot整合myabtis+mysql

一、pom.xml

<!--mysql驱动包-->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
        </dependency>

        <!--springboot与JDBC整合包-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-jdbc</artifactId>
        </dependency>
   <!--springboot与mybatis的整合包-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.0</version>
        </dependency>

二、application.yml

server:
  port: 8081
  servlet:
    session:
      timeout: 10

spring:
  servlet:
    multipart:
      max-file-size: 50MB     #单个文件最大限制
      max-request-size: 100MB  #多个文件最大限制
  # 数据源配置
  datasource:
    # 主库数据源
    master1:
      jdbcurl: jdbc:mysql://localhost/plc_xz?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true&serverTimezone=GMT%2B8
      username: root
      password: root
    # 从库数据源
    master2:
      # 从数据源开关/默认关闭
      enabled: true
      jdbcurl: jdbc:sqlserver://localhost:1433;DatabaseName=ckyw
      username: a
      password: a

  thymeleaf:
    prefix: classpath:/templates/
    suffix: .html
    mode: HTML5
    encoding: UTF-8
    content-type: text/html
    cache: false
#  web:
#    resources:
#      static-locations: classpath:/static/

mybatis:
  mapper-locations: classpath:mappers/*.xml
  type-aliases-package: com.hs.entity
  configuration:
    #开启驼峰
    map-underscore-to-camel-case: true
    cache-enabled: true


logging:
  level:
    com:
      hs:
        dao : debug

upload_url : d:/uploads/

三、启动类 SpringBootApplication.java 加 @MapperScan("com.hs.dao")注解

 注意：mapper.xm路径一般在resource下面
