# SpringBoot7_7_6

#### 介绍
数据回滚测试

#### 软件架构
SpringBoot-Data
JPA
MySQL

#### JPA和MySQL和单元测试junit的依赖

```
<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<scope>runtime</scope>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-data-jpa</artifactId>
		</dependency>
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<scope>test</scope>
		</dependency>
```

#### Applicaiton.properities中关于Mysql的一点配置

```
spring.datasource.url=jdbc:mysql://127.0.0.1/book?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC&useSSL=true
spring.datasource.username=root
spring.datasource.password=rootroot
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.properties.hibernate.hbm2ddl.auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.show-sql= true

spring.thymeleaf.cache=false
server.port=8080
```

#### 在IDEA中JPA的实体创建方式
New-JPA-Entity-[Card]
Name:类名字
EntityType:Entity
Id:int
Idgeneration:Identity
Select OK

#### 在IDEA中快速创建Responsitory
New-SpringData-Respository
Entity:上一步创建的[Card]
inputName

#### 其他说明：
@Transactional:数据回滚的意思。所有方法执行完了以后，回滚成原来的样子。在实际的测试代码中，如果将改注解注释掉，数据是不会回滚的。
Assert.assertThat过期了，需要用到MatcherAssert.assertThat
