修改底座版本号 ​

当前支持JDK17的最新版本号为：1.9.0_17

格式说明：之后会存在两种格式的版本号，如1.9.0，1.9.0_17。若存在后缀_17，表示JDK要求为17；不存在_17后缀，则JDK要求为8。

升级的技术选型 ​

JDK 17

Spring Boot 3.3.5

spring-cloud 2023.0.3

spring-cloud-alibaba 2023.0.1.3

mybatis-plus 3.5.9

knife4j 4.5.0

代码生成 ​

底座版本：存在后缀_17（例：1.9.0_17），基于JDK17进行代码生成；否则基于JDK8进行代码生成。

JDK8项目升级 ​

pom.xml文件 ​

xml
<parent>
    <groupId>cn.zjtele.pubinfo.boot</groupId>
    <artifactId>pubinfo-boot</artifactId>
    <version>jdk17版本,例如1.9.0_17</version>
</parent>

<properties>
    <maven.compiler.source>17</maven.compiler.source>
    <maven.compiler.target>17</maven.compiler.target>

</properties>

修改包路径 ​

javax -> jakarta

例如：

java
javax.annotation.Resource -> jakarta.annotation.Resource
javax.validation.Constraint -> jakarta.validation.Constraint
javax.validation.Payload -> jakarta.validation.Payload
javax.annotation.PostConstruct -> jakarta.annotation.PostConstruct

logback-spring.xml ​

converterClass -> class

xml
<conversionRule conversionWord="clr" class="org.springframework.boot.logging.logback.ColorConverter" />
<conversionRule conversionWord="wex" class="org.springframework.boot.logging.logback.WhitespaceThrowableProxyConverter" />
<conversionRule conversionWord="wEx" class="org.springframework.boot.logging.logback.ExtendedWhitespaceThrowableProxyConverter" />

yml配置文件 ​

spring.redis -> spring.data.redis

yml
spring:
  data:
    redis:
      host:
      port:
      password:
      database:

Spring Boot自动配置 ​

删除META-INF/spring.factories中的自动配置

org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.example.autoconfig.AutoConfiguration1

新增配置文件META-INF/org.springframework.boot.autoconfigure.AutoConfiguration.imports ，将自动配置类添加到此文件中

com.example.autoconfig.AutoConfiguration1
