## README

# 1. 前言
整合SpringBoot 常用技术点

# 2. 使用说明

### 2.1 数据库
创建数据库
```sql
CREATE DATABASE springboot_test CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
```

# 3. 升级3.0踩坑记录

##### 3.1 mysql 依赖错误

这是2.0版本的依赖
```xml
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
</dependency>
```
需要更换为
```xml
<dependency>
    <groupId>com.mysql</groupId>
    <artifactId>mysql-connector-j</artifactId>
    <scope>runtime</scope>
</dependency>
```

##### 3.2 servlet 包需要更改
2.0 的
```java
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
```
3.0之后的
```java
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;
import jakarta.servlet.http.HttpSession;
```

##### 3.3 mybatis-plus 升级

使用之前的 mybatis-plus 会报错 `Invalid value type for attribute 'factoryBeanObjectType': java.lang.String`

```pom
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus</artifactId>
    <version>3.5.11</version>
</dependency>
```
