# 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。

#### 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:

https://doc.xiaominfo.com/docs/quick-start/start-knife4j-version#22-spring-boot-3x

https://springdoc.org/#migrating-from-springfox

- `@Api` → `@Tag`

- `@ApiIgnore` → `@Parameter(hidden = true)` or `@Operation(hidden = true)` or `@Hidden`

- `@ApiImplicitParam` → `@Parameter`

- `@ApiImplicitParams` → `@Parameters`

- `@ApiModel` → `@Schema`

- `@ApiModelProperty(hidden = true)` → `@Schema(accessMode = READ_ONLY)`

- `@ApiModelProperty` → `@Schema`

- `@ApiOperation(value = "foo", notes = "bar")` → `@Operation(summary = "foo", description = "bar")`

- `@ApiParam` → `@Parameter`

- `@ApiResponse(code = 404, message = "foo")` → `@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

~~~java

[@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()

.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"))

);

}

升级的maven地址:

~~~xml

<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。

~~~xml

<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

~~~xml

<!-- druid -->

<dependency>

<groupId>com.alibaba</groupId>

<artifactId>druid-spring-boot-3-starter</artifactId>

<version>1.2.20</version>

</dependency>

<!-- 动态数据源 -->

<dependency>

<groupId>com.baomidou</groupId>

<artifactId>dynamic-datasource-spring-boot3-starter</artifactId>

<version>4.1.3</version>

</dependency>

<!-- spring boot-admin -->

<dependency>

<groupId>de.codecentric</groupId>

<artifactId>spring-boot-admin-starter-server</artifactId>

<version>3.0.4</version>

</dependency>
