#spring boot

1. 创建一个`springboot`应用

1.1 创建

springboot应用没有相应的archetype，不能通过mvn generate:archetype创建，一般有两种方式创建一个springboot应用：

访问 https://start.spring.io/，选择Web依赖，点击Generate Project 创建一个springboot应用。
通过IDEA：File -> New Project -> Spring Initializr -> Choose Initializr Service URL(https://start.spring.io) -> next(填写 Project Metadata) -> next -> 选择Web -> Finish

1.2 启动

mvn spring-boot:run
# 或
mvn clean spring-boot:run

1.3 @SpringBootApplication

@SpringBootApplicatoin是用的@ComponentScan扫描，扫描的是Component，包括@Component, @Controller, @Service, @Repository等。

SpringBootApplication默认扫描运行类所在包及其子包中的Component。

2. 单元测试

2.1 `spring-boot-starter-test` Starter

通常通过添加 spring-boot-starter-test "Starter"依赖来导入 Spring Boot test 模块以及 JUnit, AssertJ, Hamcrest, Spring Test, Mockito, JSONassert and JSONPath 库，如果这些库满足不了你的需要，你可以再添加其他的测试依赖。

        <!-- spring-boot-starter-test imports both Spring Boot test modules as well as JUnit, AssertJ, Hamcrest, Spring Test, Mockito, JSONassert and JSONPath -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

2.2 @SpringBootTest

A Spring Boot application is a Spring ApplicationContext, so nothing very special has to be done to test it beyond what you would normally do with a vanilla Spring context.

Spring Boot provides a @SpringBootTest annotation, which can be used as an alternative to the standard spring-test @ContextConfiguration annotation when you need Spring Boot features. The annotation works by creating the ApplicationContext used in your tests through SpringApplication.

3. 集成MyBatis

3.1 `pom.xml`中添加MyBatis依赖

        <!-- mybatis ORM 框架 -->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.0</version>
        </dependency>

        <!-- MySQL -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.35</version>
            <scope>runtime</scope>
        </dependency>

        <!-- Druid 数据库连接池 -->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.0.29</version>
        </dependency>

3.2 `application.properties`中添加相关配置

spring.datasource.url=jdbc:mysql://127.0.0.1:3306/erp?autoReconnect=true&allowMultiQueries=true&zeroDateTimeBehavior=convertToNull
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
# \u914D\u7F6E\u83B7\u53D6\u8FDE\u63A5\u7B49\u5F85\u8D85\u65F6\u7684\u65F6\u95F4
spring.datasource.maxWait=60000

# mybatis
