61+
62+
##2. application配置文件信息
63+
64+
```yml

68+

type:com.alibaba.druid.pool.DruidDataSource
74+
75+
mybatis-plus:
76+
global-config:
77+
db-config:
78+
table-prefix:tb_# 数据库表名的前缀
79+

81+
```
82+
83+
## 3. 启动类的扫描配置
84+
85+
```java
86+
package vip.msjava.examples;

91+
92+
@SpringBootApplication
93+
@MapperScan(basePackages = "vip.msjava.example.mapper")
94+
public class SpringbootApplication {
95+
96+
public static void main(String[] args) {
97+
SpringApplication.run(SpringbootApplication.class, args);
98+
}
99+
100+
}
101+
```
102+
103+
##4. 代码生成工具类
104+
105+
```java
106+

223+
}
224+
225+
226+
}
227+
228+
```
229+
230+
##5. 启动`MyBatisPlusGenerator`的Main方法
231+
232+
**输入表名即可，如果一次生成多个表信息，按照提示即可；**
233+
234+
**最终的项目结果如下图所示：**
