## spring boot整合mycat，不需要导入mycat包，只需要按照之前操作MySQL的流程去做就行，需要对SQL语句进行一些简单改造： ##

@Insert(“insert into table(字段) values(xxx,x,xxx)”)

## ①创建springboot项目 引入mysql、mybatis ##

```java
    <dependencies>
      	
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-web</artifactId>
    			<version>2.1.0.RELEASE</version>
    		</dependency>
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-starter-test</artifactId>
    			<version>2.1.0.RELEASE</version>
    		</dependency>
    		
    		<dependency>
    			<groupId>org.mybatis.spring.boot</groupId>
    			<artifactId>mybatis-spring-boot-starter</artifactId>
    			<version>1.3.2</version>
    		</dependency>
    		
      		<dependency>
    		    <groupId>mysql</groupId>
    		    <artifactId>mysql-connector-java</artifactId>
    		    <version>5.1.6</version>
    		</dependency>
    
    		
    		<dependency>
    			<groupId>org.springframework.boot</groupId>
    			<artifactId>spring-boot-devtools</artifactId>
    			<version>2.1.0.RELEASE</version>
    		</dependency>
    		
    		<dependency>
    		    <groupId>log4j</groupId>
    		    <artifactId>log4j</artifactId>
    		     <version>1.2.17</version>
    		</dependency>
      </dependencies>

## ②创建application.yml文件配置一下信息 ##

## ⑧编写启动类 ##

## 如果在程序中出现 packettoolager 问题是mysql的包版本太高，最好降低一下版本 ##
