Springboot integration MyBatis (a): run up

0x1 environment

　　1. System: Windows 10 

　　2. IDE:IntelliJ IDEA 2018.3 x64

0x2 creation project

　　1. Create a project SpringBoot

　　　　Select Spring Initailizr> Next

　　　　

　　　　

　　　　Simple configuration can> Next

　　　　

　　　　Select the desired item rely> Next

　　　　

　　　　Select the project workspace [write casually]: directory does not exist automatically creates> Next 

　　　　

　　　　Once it's created, idea will load dependencies, and pop-up prompts, Meven projects need to import dependence, select automatic pilot package

　　　　

　　　　Wait a moment .... When the progress bar on the bottom right corner there is no good explanation

　　2. Create a project structure

　　　　These three files can be deleted

　　　　

 

　　　　In order to create the directory: controller layer, domain layer (entity), mapper layer, query layer, service layer, is created like this ......

　　　　

　　

Note: This article does not use application.properties files use more concise application.yml file, you may have noticed, there are four yml project file which is why?

　　Because now there are a lot of environmental projects, development environment, test environment, quasi-production environment, production environment, different parameters for each environment, so we can put the configuration parameters for each environment to yml file

　　In Spring Boot multi environment configuration file names need to meet application- {profile} .yml format, wherein {profile} identification corresponding to your environment, such as:

　　　　application.yml: master file
　　　　application-dev.yml: development environment,
　　　　application-test.yml: Test Environment
　　　　application-prod.yml: the production environment

　　To load that file in the property set by spring.profiles.active application.yml file, which corresponds to the value {profile} value. such as

　　　　

 

　　Create a database table

　　　　

CREATE TABLE `user` (
  `id` BIGINT(32) NOT NULL AUTO_INCREMENT,
  `userName` varchar(32) NOT NULL,
  `passWord` varchar(50) NOT NULL,
  `realName` varchar(32) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

Impl directory created at the service layer and create IUserService impl implementation class and implements the following directory override inherited methods

⑥ create mapper directory in the resources, and create UserMapper.xml

　　Structure test data

INSERT INTO `springboot`.`t_user` (` id`, `userName`,` passWord`, `realName`) VALUES ( '10000001', 'admin', 'admin', ' super administrator' );
INSERT INTO `springboot`.`t_user` (`id`, `userName`, `passWord`, `realName`) VALUES ('10000002', 'user1', '123', '用户1');
INSERT INTO `springboot`.`t_user` (`id`, `userName`, `passWord`, `realName`) VALUES ('10000003', 'user2', '123', '用户2');

 

 

　　All completed only be tested

　　　Use PostMan test wave

　　　　

 

　　Success, and perfect

　　

 

 

Pit:

　　java.sql.SQLException: The server time zone value '�й���׼ʱ��' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.

 

Modify the configuration file:

url: jdbc: mysql: // localhost :? 3306 / springboot useUnicode = & characterEncoding = utf-8 & useSSL = true & serverTimezone = UTC true
