• 从零开始学习springBoot(myqsl链接+端口修改+jpa映射)


    1.修改端口号:在application.properties文件添加:server.port=9090   就能将端口号修改为9090

    2.连接数据库:

    2.1:修改pom.xml  添加

    2.2:application.properties文件添加:

      ########################################################
      ###datasource
      ########################################################
      spring.datasource.url = jdbc:mysql://localhost:3306/fy
      spring.datasource.username = root
      spring.datasource.password = root
      spring.datasource.driverClassName = com.mysql.jdbc.Driver
      spring.datasource.max-active=20
      spring.datasource.max-idle=8
      spring.datasource.min-idle=8
      spring.datasource.initial-size=10


      ########################################################
      ### JPA
      ########################################################
      # Specify the DBMS
      spring.jpa.database = MYSQL
      spring.jpa.show-sql = true
      spring.jpa.hibernate.ddl-auto = update
      spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
      spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

    3.添加dao接口

    4.编写service类

    5.写一个controller类

    6.访问http://127.0.0.1:9090/demo2/save

    7.数据库会保存一条数据
