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...

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-vers...

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

[@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:

        <dependency>

            <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。

            <groupId>com.github.xiaoymin</groupId>
            <artifactId>knife4j-gateway-spring-boot-starter</artifactId>
            <version>4.3.0</version>
        </dependency>
