集成Mybatis持久层框架
让我们改一下启动图形
Banner字符可以通过类似以下网站生成：

在resources文件夹下新建banner.txt，里面放入制作的图形即可

启动后就会显示出来
pom添加依赖
<!--集成 MyBatis 框架-->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.2</version>
</dependency>
创建一个配置文件MybatisConfig.java用来扫描DAO，model，mapper
package com.example.springboot.config;
import javax.sql.DataSource;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
@Configuration
@MapperScan("com.example.**.dao") // 扫描DAO
public class MybatisConfig {
@Autowired
private DataSource dataSource;
@Bean
public SqlSessionFactory sqlSessionFactory() throws Exception {
SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
sessionFactory.setDataSource(dataSource);
sessionFactory.setTypeAliasesPackage("com.example.**.model"); // 扫描Model
PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
sessionFactory.setMapperLocations(resolver.getResources("classpath*:mapper/*.xml")); // 扫描映射文件
return sessionFactory.getObject();
}
}
修改配置文件applicaton.properties为application.yml，本质上两个文件的功能都一样，不过我喜欢后一种，看着简洁点
application.yml配置文件中添加服务，更改端口的话就把port给改了，我的是8080
# Tomcat
server:
tomcat:
uri-encoding: UTF-8
max-threads: 1000
min-spare-threads: 30
port: 8080
servlet:context-path: /
pom添加热部署和mysql依赖
<!--添加热部署-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
<optional>true</optional>
</dependency>
<!-- mysql -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.11</version>
</dependency>
application.yml配置mysql
spring:
datasource:
driverClassName: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/kitty?useUnicode=true&characterEncoding=utf-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
username: root
password: root
现在的application.yml
