本文主要整理了在升级springboot3的过程中遇到的问题.

升级`spring-boot3`后代码中的`javax`包需要切换为`jakarta`

项目中使用到了apache-guacamole-common依赖, 该依赖中使用了javax包

解决方案

由于该依赖目前最新的版本还没有升级到jakarta, 所以需要相关依赖代码复制到项目中, 并将javax包切换为jakarta.

querydsl依赖变更

由于springboot3中的javax依赖变为了jakarta, 所以querydsl的依赖也需要变更

解决方案

将querydsl相关依赖的classfiier设置为jakarta.

build.kts
implementation("com.querydsl:querydsl-jpa:5.0.0:jakarta")
kapt("com.querydsl:querydsl-apt:5.0.0:jakarta")

升级`spring-boot3`后访问由`@PreAuthorize`注解保护的接口报错

升级spring-boot3后访问由@PreAuthorize注解保护的接口报错, 报错为401

原因

RoleHierarchy失效, 导致MGMT_SUPER_ADMIN无法访问@PreAuthorize("hasRole("MGMT_ADMIN")")注解保护的接口。
因为MGMT_SUPER_ADMIN继承自MGMT_ADMIN。
这个问题的原因是由@EnableGlobalMethodSecurity到@EnableMethodSecurity的迁移导致。
这两者内部对于defaultMethodExpressionHandler的初始化行为不一致导致RoleHierarchy失效。
区别如下

@EnableGlobalMethodSecurity
实现类GlobalMethodSecurityConfiguration创建defaultMethodExpressionHandler时会尝试从容器中获取RoleHierarchy。
@EnableMethodSecurity
实现类PrePostMethodSecurityConfiguration创建defaultMethodExpressionHandler时不会从容器中获取RoleHierarchy。

解决方案

为spring-security创建pull request确保初始化defaultMethodExpressionHandler行为保持一致
对于自身项目当前的解决办法是初始化MethodExpressionHandler

备注

GlobalMethodSecurityConfiguration.java
public class GlobalMethodSecurityConfiguration implements ImportAware, SmartInitializingSingleton, BeanFactoryAware {

	@Override
	public void afterSingletonsInstantiated() {
		try {
			initializeMethodSecurityInterceptor();
		} catch (Exception ex) {
			throw new RuntimeException(ex);
		}
		PermissionEvaluator permissionEvaluator = getSingleBeanOrNull(PermissionEvaluator.class);
		if (permissionEvaluator != null) {
			this.defaultMethodExpressionHandler.setPermissionEvaluator(permissionEvaluator);
		}
		RoleHierarchy roleHierarchy = getSingleBeanOrNull(RoleHierarchy.class);
		if (roleHierarchy != null) {
			this.defaultMethodExpressionHandler.setRoleHierarchy(roleHierarchy);
		}
		AuthenticationTrustResolver trustResolver = getSingleBeanOrNull(AuthenticationTrustResolver.class);
		if (trustResolver != null) {
			this.defaultMethodExpressionHandler.setTrustResolver(trustResolver);
		}
		GrantedAuthorityDefaults grantedAuthorityDefaults = getSingleBeanOrNull(GrantedAuthorityDefaults.class);
		if (grantedAuthorityDefaults != null) {
			this.defaultMethodExpressionHandler.setDefaultRolePrefix(grantedAuthorityDefaults.getRolePrefix());
		}

		this.defaultMethodExpressionHandler = this.objectPostProcessor.postProcess(this.defaultMethodExpressionHandler);
	}

}

PrePostMethodSecurityConfiguration.java
final class PrePostMethodSecurityConfiguration {

	private static MethodSecurityExpressionHandler defaultExpressionHandler(
		ObjectProvider<GrantedAuthorityDefaults> defaultsProvider, ApplicationContext context) {
		DefaultMethodSecurityExpressionHandler handler = new DefaultMethodSecurityExpressionHandler();
		defaultsProvider.ifAvailable((d) -> handler.setDefaultRolePrefix(d.getRolePrefix()));
		handler.setApplicationContext(context);
		return handler;
	}

升级`spring-boot3`后使用Token请求保护资源报错

使用Token请求保护资源报错401

原因

这个问题的原因是spring-security中进行了重构需要对securityContext进行配置

解决方案

http.securityContext().requireExplicitSave(false).and()
http.securityContext().securityContextRepository(new HttpSessionSecurityContextRepository()).and()

备注

spring6之后SecurityContextHolderFilter替换了SecurityContextPersistenceFilter
SecurityContextRepository默认实现也变了
(HttpSessionSecurityContextRepository) -> (RequestAttributeSecurityContextRepository)

升级`spring-boot3`后请求`/swagger-ui/index.html`报错

接口报错, 内容如下

chrome
This page isn’t working
If the problem continues, contact the site owner.
HTTP ERROR 401

原因

springdoc版本过老, 需要升级到v2版本。
springdoc.org 上的有相关说明For spring-boot v3 support, make sure you use springdoc-openapi v2

本项目的原始配置如下

pom.xml

<dependency>
	<groupId>org.springdoc</groupId>
	<artifactId>springdoc-openapi-ui</artifactId>
	<version>1.6.14</version>
</dependency>

解决方案

升级springdoc版本到v2, 升级后的配置如下, v2的artifactId发生了变化

pom.xml

<dependency>
	<groupId>org.springdoc</groupId>
	<artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
	<version>2.0.2</version>
</dependency>

	if (this.logger.isTraceEnabled()) {
		this.logger.trace(LogMessage.format("Checking authorization on %s using %s", request, manager));
	}
	// 后续命中了Mvc [pattern='/*/*.html']对应的Matcher, 而该Matcher对应的匹配规则要求需要`authentication`不为空, 导致报错
	return manager.check(authentication, new RequestAuthorizationContext(request, matchResult.getVariables()));
}

api接口报错后没有返回异常信息

解决方案

新版本的spring-boot默认不返回异常信息, 需要在application.yml中增加以下配置

server:
  error:
    include-message: always
