    </dependency>
</dependencies>

2.2 安全架构升级

Spring Security 6.x配置迁移

@Configuration
@EnableWebSecurity
public class SecurityConfig {
    
    @Bean
    @Order(1)
    public SecurityFilterChain apiFilterChain(HttpSecurity http) throws Exception {
        http
            .securityMatcher("/api/**")
            .authorizeHttpRequests(auth -> auth
                .requestMatchers("/api/public/**").permitAll()
                .anyRequest().authenticated()
            )
            .oauth2ResourceServer(OAuth2ResourceServerConfigurer::jwt);
        
        return http.build();
    }
    
    @Bean
    public SecurityFilterChain formLoginFilterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(auth -> auth
                .requestMatchers("/login", "/captchaImage").permitAll()
                .requestMatchers(HttpMethod.GET, "/**/*.css", "/**/*.js").permitAll()
                .anyRequest().authenticated()
            )
            .formLogin(form -> form
                .loginPage("/login")
                .successHandler(authenticationSuccessHandler())
                .failureHandler(authenticationFailureHandler())
            )
            .rememberMe(remember -> remember
                .key("uniqueAndSecret")
                .tokenValiditySeconds(86400)
            )
            .logout(logout -> logout
                .logoutUrl("/logout")
                .logoutSuccessHandler(logoutSuccessHandler())
            )
            .csrf(csrf -> csrf.disable());
        
        return http.build();
    }
}

2.3 持久层优化方案

MyBatis-Plus 3.5.x增强特性

// 新版动态表名处理器
public class DynamicTableNameInterceptor implements InnerInterceptor {
    
    private final ThreadLocal<String> tableName = new ThreadLocal<>();
    
    public void setTableName(String name) {
        tableName.set(name);
    }
    
    @Override
    public void beforeQuery(Executor executor, MappedStatement ms, 
            Object parameter, RowBounds rowBounds, ResultHandler resultHandler, 
            BoundSql boundSql) {
        
        if (tableName.get() != null) {
            BoundSql newBoundSql = new BoundSql(
                ms.getConfiguration(),
                boundSql.getSql().replace("original_table", tableName.get()),
                boundSql.getParameterMappings(),
                parameter
            );
            resetSql(ms, boundSql, newBoundSql);
        }
    }
}

// 新版Lambda查询
public List<SysUser> selectUsersByCondition(UserQuery query) {
    return lambdaQuery()
        .select(SysUser::getUserId, SysUser::getUserName)
        .eq(query.getDeptId() != null, SysUser::getDeptId, query.getDeptId())
        .like(StringUtils.isNotBlank(query.getUserName()), 
              SysUser::getUserName, query.getUserName())
        .between(query.getBeginTime() != null && query.getEndTime() != null,
                SysUser::getCreateTime, query.getBeginTime(), query.getEndTime())
        .list();
}

三、关键技术突破点

3.1 响应式编程支持

WebFlux集成方案

@RestController
@RequestMapping("/reactive/users")
public class ReactiveUserController {
    
    private final ReactiveUserService userService;
    
    @GetMapping("/{id}")
    public Mono<Result<SysUser>> getUser(@PathVariable Long id) {
        return userService.findById(id)
            .map(Result::success)
            .onErrorResume(e -> Mono.just(Result.error(e.getMessage())));
    }
    
    @GetMapping
    public Flux<SysUser> listUsers(UserQuery query) {
        return userService.findList(query)
            .delayElements(Duration.ofMillis(100)) // 背压控制
            .timeout(Duration.ofSeconds(5));
    }
}

// 响应式Repository
public interface ReactiveUserRepository extends R2dbcRepository<SysUser, Long> {
    
    @Query("SELECT * FROM sys_user WHERE dept_id = :deptId")
    Flux<SysUser> findByDeptId(Long deptId);
    
    Mono<SysUser> findByUserName(String username);
}

3.2 原生镜像支持

GraalVM Native Image配置

# application-native.properties
spring.aot.enabled=true
spring.sql.init.mode=never

# 反射配置示例
@TypeHint(types = {
    com.ruoyi.common.core.domain.model.LoginUser.class,
    com.ruoyi.common.exception.GlobalExceptionHandler.class
}, access = { TypeAccess.DECLARED_CONSTRUCTORS, TypeAccess.DECLARED_METHODS })
public class NativeConfig implements RuntimeHintsRegistrar {
    
    @Override
    public void registerHints(RuntimeHints hints, ClassLoader classLoader) {
        // 注册反射
        hints.reflection().registerType(LoginUser.class, MemberCategory.values());
        
        // 资源文件注册
        hints.resources().registerPattern("templates/*.html");
        
        // 序列化配置
        hints.serialization().registerType(Result.class);
    }
}

四、企业级特性增强

4.1 多租户架构升级

// 基于Schema的多租户实现
public class TenantSchemaInterceptor extends AbstractSqlParserHandler 
    implements InnerInterceptor {
    
    @Override
    public void beforeQuery(Executor executor, MappedStatement ms, 
            Object parameter, RowBounds rowBounds, ResultHandler resultHandler, 
            BoundSql boundSql) {
        
        String tenantId = TenantContext.getCurrentTenant();
        if (StringUtils.isNotBlank(tenantId)) {
            String sql = boundSql.getSql();
            String newSql = sql.replace("from ", "from " + tenantId + ".");
            resetSql(ms, boundSql, newSql);
        }
    }
}

// 动态数据源路由
public class TenantDataSourceRouter extends AbstractRoutingDataSource {
    
    @Override
    protected Object determineCurrentLookupKey() {
        String tenantId = TenantContext.getCurrentTenant();
        return tenantId != null ? tenantId : "master";
    }
    
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource.druid.master")
    public DataSource masterDataSource() {
        return DruidDataSourceBuilder.create().build();
    }
    
    @Bean
    public DataSource tenantDataSource() {
        Map<Object, Object> targetDataSources = new HashMap<>();
        targetDataSources.put("master", masterDataSource());
        TenantDataSourceRouter router = new TenantDataSourceRouter();
        router.setDefaultTargetDataSource(masterDataSource());
        router.setTargetDataSources(targetDataSources);
        return router;
    }
}

4.2 分布式事务强化

Seata 2.x集成方案

# application.yml 配置
seata:
  enabled: true
  application-id: ruoyi-system
  tx-service-group: ruoyi_tx_group
  service:
    vgroup-mapping:
      ruoyi_tx_group: default
    disable-global-transaction: false
  config:
    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848
      namespace: dev
      group: SEATA_GROUP
  registry:
    type: nacos
    nacos:
      application: seata-server
      server-addr: 127.0.0.1:8848
      namespace: dev
      group: SEATA_GROUP

// 分布式事务使用示例
@GlobalTransactional
public void transfer(Long fromId, Long toId, BigDecimal amount) {
    accountService.debit(fromId, amount);
    accountService.credit(toId, amount);
    
    // 模拟业务异常
    if (amount.compareTo(new BigDecimal("100000")) > 0) {
        throw new RuntimeException("超额转账限制");
    }
}

五、性能优化实践

5.1 启动加速方案

// 延迟初始化配置
@SpringBootApplication
@LazyInitialization(
    value = "!com.ruoyi.system.*",  // 系统模块不延迟加载
    exclude = {
        DataSourceInitializer.class,
        CacheManager.class
    }
)
public class RuoYiApplication {
    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(RuoYiApplication.class);
        app.setLazyInitialization(true);  // 全局开启延迟初始化
        app.run(args);
    }
}

// 编译时AOT优化
@Configuration(proxyBeanMethods = false)  // 禁用CGLIB代理
public class OptimizedConfig {
    
    @Bean
    public ThreadPoolTaskExecutor taskExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(Runtime.getRuntime().availableProcessors());
        executor.setThreadNamePrefix("Async-");
        return executor;
    }
}

5.2 内存优化策略

// 堆外内存管理
@Bean(destroyMethod = "release")
public PooledByteBufAllocator nettyBufferAllocator() {
    return new PooledByteBufAllocator(
        PlatformDependent.directBufferPreferred(),
        Runtime.getRuntime().availableProcessors(),
        256,  // 每区域页数
        64,   // 最大阶数
        16,   // 页大小
        64,   // 堆缓存阈值
        32,   // 直接内存缓存阈值
        3     // 缓存回收频率
    );
}

// 缓存优化配置
@Configuration
@EnableCaching(mode = AdviceMode.ASPECTJ)  // 使用AspectJ避免动态代理
public class CacheConfig implements CachingConfigurer {
    
    @Bean
    public CacheManager cacheManager() {
        CaffeineCacheManager manager = new CaffeineCacheManager();
        manager.setCaffeine(Caffeine.newBuilder()
            .maximumSize(1000)
            .expireAfterWrite(10, TimeUnit.MINUTES)
            .recordStats());
        return manager;
    }
    
    @Bean
    public KeyGenerator multiKeyGenerator() {
        return (target, method, params) -> {
            StringBuilder key = new StringBuilder();
            key.append(target.getClass().getSimpleName());
            key.append(":").append(method.getName());
            for (Object param : params) {
                if (param != null) {
                    key.append(":").append(param.toString());
                }
            }
            return key.toString();
        };
    }
}

六、迁移路线图

6.1 分阶段升级策略

1. 准备阶段（1-2周）

   • JDK 17环境验证
   • 依赖兼容性分析（使用mvn dependency:tree）
   • 制定回滚方案

2. 基础改造阶段（2-3周）

   • Jakarta EE包名替换
   • Spring Security 6配置迁移
   • 测试环境验证

3. 增强特性阶段（可选，1-2周）

   • 响应式编程改造
   • 原生镜像编译支持
   • 性能调优

4. 全量上线阶段（1周）

   • 灰度发布策略
   • 监控指标埋点
   • 应急预案执行

6.2 常见问题解决方案

问题1：javax包找不到错误
解决：使用IDE全局替换javax.为jakarta.（注意排除JPA实体注解）

问题2：Spring Security 5到6的鉴权失败
解决：更新配置方式并添加请求匹配器：

http.authorizeHttpRequests(registry -> registry
    .requestMatchers("/static/**").permitAll()
    .anyRequest().authenticated()
);

问题3：MyBatis映射文件兼容性问题
解决：更新DTD声明并检查参数类型：

<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" 
    "https://mybatis.org/dtd/mybatis-3-mapper.dtd">

结语：面向未来的技术布局

RuoYi-Vue-Plus 5.x与Spring Boot 3.x的结合，为企业级应用开发带来三大核心价值：

1. 性能飞跃：基于虚拟线程（Loom）和原生镜像的极致性能
2. 云原生就绪：完善的Kubernetes和Service Mesh集成能力
3. 长期支持：获得Spring官方5年以上的维护周期

以下是推荐的新项目启动模板：

@SpringBootApplication
public class NextGenApplication {
    
    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(NextGenApplication.class);
        
        // 启用虚拟线程
        app.setWebApplicationType(WebApplicationType.SERVLET);
        app.setBeanNameGenerator(new DefaultBeanNameGenerator());
        app.addListeners(new ApplicationPidFileWriter());
        
        // 生产环境建议添加的配置
        if (NativeDetector.inNativeImage()) {
            app.setAot(true);
            app.setLazyInitialization(true);
        }
        
        app.run(args);
    }
}

通过本次技术升级，RuoYi-Vue-Plus将为企业数字化转型提供更强大的技术支撑，建议开发团队重点关注：

• 响应式编程的渐进式采用
• GraalVM原生镜像的编译优化
• JDK 21新特性（如虚拟线程）的落地实践
