背景

Spring Boot 2.x 升级到 Spring Boot 3.x 需要使用Java 17或更高版本，所以有些地方需要改动

pom.xml文件改动

修改pom.xml文件，version版本根据实际情况配置最新。

<!-- java.version版本8更换为17 -->
<java.version>17</java.version><!-- 新增节点 -->
<mybatis-spring-boot.version>3.0.3</mybatis-spring-boot.version>
<mysql.version>8.2.0</mysql.version>
<jaxb-api.version>2.3.1</jaxb-api.version>
<jakarta.version>6.0.0</jakarta.version>
<springdoc.version>2.5.0</springdoc.version><!-- spring-boot版本2.5.15更换为3.3.0 -->
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-dependencies</artifactId><version>3.3.0</version><type>pom</type><scope>import</scope>
</dependency><!-- 新增四个配置依赖 -->
<dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>${mybatis-spring-boot.version}</version>
</dependency><dependency><groupId>com.mysql</groupId><artifactId>mysql-connector-j</artifactId><version>${mysql.version}</version>
</dependency><dependency><groupId>javax.xml.bind</groupId><artifactId>jaxb-api</artifactId><version>${jaxb-api.version}</version>
</dependency><dependency><groupId>jakarta.servlet</groupId><artifactId>jakarta.servlet-api</artifactId><version>${jakarta.version}</version>
</dependency>

Java EE转Jakarta EE

Spring Boot 3.0将所有底层依赖项从Java EE迁移到了Jakarta EE，会对一些使用了Java EE的方法造成影响，需要进行相应的修改和调整。

将javax.xxxx替换成jakarta.xxxx，例如

javax.annotation 替换成 jakarta.validation
javax.servlet    替换成 jakarta.servlet
javax.validation 替换成 jakarta.validation
javax.xxxxxxxxxx 替换成 jakarta.xxxxxxxxxx

但是有些原生方法是不需要去进行修改的，例如项目中的这几个方法，包不需要替换成jakarta.xxxx

import javax.imageio.ImageIO;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import javax.sql.DataSource

修改SecurityConfig.java

修改SecurityConfig.java，以支持Spring Security6新的配置方式。

修改application.yml的spring.redis配置

修改application.yml的spring.redis配置为spring.data.redis
