JeecgBoot 框架升级至 Spring Boot3 的实战步骤
JeecgBoot 框架升级 Spring Boot 3.1.5 步骤
JEECG官方推出SpringBoot3分支:https://github.com/jeecgboot/jeecg-boot/tree/springboot3
本次更新由于属于破坏式更新,有几个生态内的组件,无法进行找到平替或无法升级,目前尚不完善,部分功能选择直接注释的方式,以下为功能列表
- Online功能
- 积木报表功能
- 仪表盘功能
- spring cloud gateway 的 SentinelFilterContextConfig 过滤器
Spring Boot
从 2.7.10升级到3.1.5有以下几个点需要注意。
- JDK版本支持从JDK 17-19版本
- javax.servlet切换到jakarta.servlet
- spring.redis配置切换为spring.data.redis
- Spring Cloud 2022.0.4
- Spring Cloud Alibaba 2022.0.0.0
除以上三点外,其它都是平滑升级,不过这也只是相对于我们应用Spring Boot的用户来说。不过对于第二点,属于是破坏性升级了,需要将项目中引用的javax.servlet替换成jakarta.servlet。
spring boot升级参考文档:https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-3.0-Migration-Guide
spring cloud升级参考文档:https://docs.spring.io/spring-cloud/docs/current/reference/html/
spring cloud alibaba升级参考文档:https://sca.aliyun.com/zh-cn/docs/2022.0.0.0/overview/version-explain
Shiro
前面讲到由于Spring Boot内部的servlet包换掉了,jeecg框架使用shiro以及spring boot集成,所以shiro需要升级,不过还好shiro官方给这个点提供了支持,以下是shiro的升级替换。
需要注意的是,spring boot 3.1.5对jedis的版本做了提升,提升后shiro无法兼容,所以只能在项目进行降版本处理。
shiro升级参考文档:https://blog.csdn.net/weixin_43492211/article/details/131217344

knife4j
knife4j对于spring boot 3.X版本提供了支持,不过相当于spring boot 2.X的版本来说,差异比较大,从springfox转换成了springdoc,不能做到平滑升级,以下是需要替换的注解列表.
knife4j升级参考文档:

@ApiParam

→@ApiResponse(responseCode = "404", description = "foo")
同样在初始化文档对象上也有区别,以下前后替换
[@Bean](https://my.oschina.net/bean)
public GroupedOpenApi swaggerOpenApi() {
return GroupedOpenApi.builder()
.group("default")
.packagesToScan("org.jeecg")
.build();
}
[@Bean](https://my.oschina.net/bean)
public OpenAPI customOpenAPI() {
return new OpenAPI()
.info(new Info()
.title("JeecgBoot 后台服务API接口文档")
.version("1.0")
.contact(new Contact().name("北京国炬信息技术有限公司").url("www.jeccg.com").email("jeecgos@163.com"))
.description( "后台API接口")
.termsOfService("NO terms of service")
.license(new License().name("Apache 2.0").url("http://www.apache.org/licenses/LICENSE-2.0.html"))
);
}
// ---------------------------替换后---------------------
[@Bean](https://my.oschina.net/bean)
public GroupedOpenApi swaggerOpenApi() {
return GroupedOpenApi.builder()
.group("default")
.packagesToScan("org.jeecg")
.build();
}
[@Bean](https://my.oschina.net/bean)
public OpenAPI customOpenAPI() {
return new OpenAPI()
.info(new Info()

.termsOfService("NO terms of service")

);
}
升级的maven地址:
<dependency>
<groupId>com.github.xiaoymin</groupId>
<artifactId>knife4j-openapi3-jakarta-spring-boot-starter</artifactId>
<version>4.3.0</version>
</dependency>
在knife4j 4.X版本中,首次在对swagger文档与spring cloud gateway进行了整合,提供完整的解决方案,做到了开箱即用,以下是应用案例,在jeecg中也得到了升级。
<dependency>
<groupId>com.github.xiaoymin</groupId>
<artifactId>knife4j-gateway-spring-boot-starter</artifactId>
<version>4.3.0</version>
</dependency>
spring boot 3.x 生态增强平滑升级
以下为平滑升级,即更换版本即可,不需要做任何调整,jeecg框架调整如下
