在工程的pom文件的properties中添加代码，分别引入mybatis，dynamic-datasource，mysql-connector
问尤龙の时光
<mybatisplus.version>3.3.1</mybatisplus.version>
<dynamic-datasource-spring-boot-starter.version>3.2.0</dynamic-datasource-spring-boot-starter.version>
<mysql-connector-java.version>8.0.27</mysql-connector-java.version>
在工程的pom文件中添加依赖
<!-- mybatis-plus -->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-boot-starter</artifactId>
<version>${mybatisplus.version}</version>
</dependency>
<!-- 动态数据源 -->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>dynamic-datasource-spring-boot-starter</artifactId>
<version>${dynamic-datasource-spring-boot-starter.version}</version>
</dependency>
<!--mysql-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>${mysql-connector-java.version}</version>
<scope>runtime</scope>
</dependency>
中新建三个配置文件application.yml、application-dev.yml、application-prod.yml，dev和prod文件对应开发环境和生产环境
application.yml文件内容如下
spring:
application:
name: bs-boot-system
profiles:
active: dev
# active: prod
application-dev.yml文件内容如下
server:
port: 8082
servlet:
context-path: /bs
servlet:

max-request-size: 10MB

#mybatis plus 设置
mybatis-plus:
# mybatis的xml文件地址
mapper-locations: classpath*:cn/com/wenyl/bs/**/xml/*Mapper.xml
global-config:
# 关闭MP3.0自带的banner
banner: false
db-config:

# 处理查询空值

application-prod.yml文件配置与dev文件相同，根据生产环境去更改地址，用户名密码信息即可
新增启动类内容如下，需要在这里配置Mapper接口的扫描路径
package cn.com.wenyl.bs;
import lombok.extern.slf4j.Slf4j;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
@MapperScan(value={"cn.com.wenyl.bs.**.mapper*"})
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
public class BSBootApplication {
public static void main(String[] args){
SpringApplication.run(BSBootApplication.class);
}
}
