<parent>
<groupId>com.kfyty</groupId>
<artifactId>loveqq-framework</artifactId>
<version>1.1.5</version>
</parent>
<dependencies>
<dependency>
<groupId>com.kfyty</groupId>
<artifactId>loveqq-boot</artifactId>
</dependency>
<dependency>
<groupId>com.kfyty</groupId>
<artifactId>loveqq-boot-starter-logback</artifactId>
</dependency>
<dependency>
<groupId>com.kfyty</groupId>
<artifactId>loveqq-boot-starter-tomcat</artifactId>
</dependency>
</dependencies>
- 创建主应用类:
@EnableWebMvc
@RestController
@BootApplication
@RequestMapping(expose = true)
public class HelloWorldApplication {
public static void main(String[] args) {
K.run(HelloWorldApplication.class, args);
}
@GetMapping("/hello")
public String hello() {
return "Hello, loveqq-framework!";
}
}
- 创建配置文件
application.yml:
k:
server:
port: 8080
mvc:
tomcat:
maxThreads: 100
- 运行应用:
mvn spring-boot:run
- 访问测试:
curl http://localhost:8080/hello
Gradle项目配置
对于Gradle项目,添加以下配置:
apply plugin: 'java'
group = 'com.kfyty.example'
version = '1.0-SNAPSHOT'
ext {
bootLibOutput = 'boot-lib'
bootMainClass = 'com.kfyty.loveqq.framework.core.support.BootLauncher'
bootStartClass = 'com.kfyty.demo.HelloWorldApplication'
}
dependencies {
implementation 'com.kfyty:loveqq-framework:1.1.5@pom'
implementation 'com.kfyty:loveqq-boot'
implementation 'com.kfyty:loveqq-boot-starter-logback'
implementation 'com.kfyty:loveqq-boot-starter-tomcat'
}
// 复制依赖
tasks.register('copyDependencies', Copy) {
from configurations.runtimeClasspath
into "$buildDir/libs/$rootProject.ext.bootLibOutput"
}
// 构建jar index
tasks.register('buildJarIndex', JavaExec) {
mainClass = 'com.kfyty.loveqq.framework.core.support.task.BuildJarIndexAntTask'
classpath = configurations.runtimeClasspath
args "-OUTPUT_DIRECTORY=$project.buildDir/libs"
args "-OUTPUT_JAR=$project.name-$project.version.jar"
args "-OUTPUT_DEFAULT_JAR=$project.name-$project.version.jar"
}
// 覆盖默认jar任务
jar {
dependsOn copyDependencies
manifest {
attributes 'Main-Class': "$rootProject.ext.bootMainClass"
attributes 'Start-Class': "$rootProject.ext.bootStartClass"
attributes 'Class-Path': configurations.runtimeClasspath.files.collect {
"$rootProject.ext.bootLibOutput/$it.name"
}.join(' ')
}
}
build {
dependsOn buildJarIndex
}
核心功能详解
IOC容器与依赖注入
loveqq-framework的IOC容器实现于loveqq-boot模块,提供了完整的依赖注入功能:
@Service
public class UserService {
private final UserRepository userRepository;
// 构造器注入
public UserService(UserRepository userRepository) {
this.userRepository = userRepository;
}
// 方法注入
@Autowired
public void setRoleService(RoleService roleService) {
this.roleService = roleService;
}
// 字段注入
@Value("${user.default.age:18}")
private int defaultAge;
}
作用域管理
框架支持多种Bean作用域:
// 单例作用域(默认)
@Singleton
@Component
public class SingletonBean { ... }
// 原型作用域
@Prototype
@Component
public class PrototypeBean { ... }
// 懒加载
@Lazy
@Component
public class LazyBean { ... }
// 刷新作用域(配置变更时重建)
@RefreshScope
@Component
public class RefreshableBean { ... }
循环依赖处理
loveqq-framework提供两种优雅解决循环依赖的方案:
// 方案1:在类上添加@Lazy注解
@Lazy
@Component
public class CycleBeanA {
private final CycleBeanB cycleBeanB;
public CycleBeanA(CycleBeanB cycleBeanB) {
this.cycleBeanB = cycleBeanB;
}
}
@Component
public class CycleBeanB {
private final CycleBeanA cycleBeanA;
// 方案2:在构造器参数上添加@Lazy注解
public CycleBeanB(@Lazy CycleBeanA cycleBeanA) {
this.cycleBeanA = cycleBeanA;
}
}
AOP编程
loveqq-aop模块提供了强大的面向切面编程支持:
@Aspect
@Component
public class LoggingAspect {
// 切入点:匹配com.kfyty.service包下所有类的所有方法
@Pointcut("execution(* com.kfyty.service.*.*(..))")
public void serviceMethods() {}
// 前置通知
@Before("serviceMethods()")
public void beforeServiceMethod(JoinPoint joinPoint) {
log.info("调用方法: {},参数: {}",
joinPoint.getSignature().getName(),
Arrays.toString(joinPoint.getArgs()));
}
// 环绕通知
@Around("serviceMethods()")
public Object aroundServiceMethod(ProceedingJoinPoint joinPoint) throws Throwable {
long start = System.currentTimeMillis();
try {
return joinPoint.proceed();
} finally {
log.info("方法执行耗时: {}ms", System.currentTimeMillis() - start);
}
}
}
Web开发
MVC配置
通过@EnableWebMvc注解快速启用Web功能:
@EnableWebMvc
@BootApplication
public class WebApplication {
public static void main(String[] args) {
K.run(WebApplication.class, args);
}
}
控制器开发
@RestController
@RequestMapping("/api/users")
public class UserController {
private final UserService userService;
public UserController(UserService userService) {
this.userService = userService;
}
@GetMapping("/{id}")
public User getUser(@PathVariable Long id) {
return userService.findById(id);
}
@PostMapping
public User createUser(@Valid @RequestBody User user) {
return userService.create(user);
}
@PutMapping("/{id}")
public User updateUser(@PathVariable Long id, @RequestBody User user) {
return userService.update(id, user);
}
@DeleteMapping("/{id}")
public void deleteUser(@PathVariable Long id) {
userService.delete(id);
}
}
请求参数验证
结合JSR-303验证规范:
@Data
public class User {
@NotNull(message = "ID不能为空")
private Long id;
@NotBlank(message = "用户名不能为空")
@Length(min = 2, max = 20, message = "用户名长度必须在2-20之间")
private String username;
@Email(message = "邮箱格式不正确")
private String email;
// 自定义条件验证
@Condition(when = "type == 1",
then = "photo != null",
message = "类型为1时,头像不能为空")
private Integer type;
private String photo;
}
数据访问
数据源配置
k:
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/loveqq_demo?useSSL=false&serverTimezone=UTC
username: root
password: password
hikari:
maximum-pool-size: 20
minimum-idle: 5
idle-timeout: 300000
connection-timeout: 20000
MyBatis集成
添加依赖:
<dependency>
<groupId>com.kfyty</groupId>
<artifactId>loveqq-boot-starter-mybatis</artifactId>
</dependency>
定义Mapper接口:
@Mapper
public interface UserMapper {
@Select("SELECT * FROM user WHERE id = #{id}")
User findById(Long id);
@Insert("INSERT INTO user(username, email) VALUES(#{username}, #{email})")
@Options(useGeneratedKeys = true, keyProperty = "id")
void insert(User user);
@Update("UPDATE user SET username = #{username}, email = #{email} WHERE id = #{id}")
void update(User user);
@Delete("DELETE FROM user WHERE id = #{id}")
void delete(Long id);
}
缓存支持
loveqq-cache提供强大的缓存功能:
@Service
public class UserService {
private final UserRepository userRepository;
public UserService(UserRepository userRepository) {
this.userRepository = userRepository;
}
// 缓存结果
@Cacheable(value = "user", key = "#id")
public User findById(Long id) {
return userRepository.findById(id)
.orElseThrow(() -> new NotFoundException("用户不存在"));
}
// 更新缓存
@CachePut(value = "user", key = "#user.id")
public User update(User user) {
return userRepository.save(user);
}
// 删除缓存
@CacheEvict(value = "user", key = "#id")
public void delete(Long id) {
userRepository.deleteById(id);
}
// 清空缓存
@CacheEvict(value = "user", allEntries = true)
@Scheduled(fixedRate = 86400000) // 每天清空一次
public void clearCache() {
log.info("清除用户缓存");
}
}
企业级特性
异步编程
框架提供简洁的异步编程模型:
@Service
public class AsyncService {
// 异步执行
@Async
public CompletableFuture<User> findUserAsync(Long id) {
return CompletableFuture.supplyAsync(() -> {
// 模拟耗时操作
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
return null;
}
return userRepository.findById(id).orElse(null);
});
}
// 响应式异步
@Async
public Mono<User> findUserReactive(Long id) {
return Mono.fromSupplier(() -> {
// 模拟耗时操作
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
return null;
}
return userRepository.findById(id).orElse(null);
});
}
// 异步等待
@Async.Await
public void processUsers(List<Long> ids) {
List<CompletableFuture<User>> futures = ids.stream()
.map(this::findUserAsync)
.collect(Collectors.toList());
// 自动等待所有异步操作完成
List<User> users = futures.stream()
.map(CompletableFuture::join)
.collect(Collectors.toList());
// 处理用户数据
users.forEach(user -> {
// ...
});
}
}
事件驱动
基于事件驱动的编程模型:
// 定义事件
@Data
public class UserCreatedEvent {
private final User user;
private final LocalDateTime createdAt;
public UserCreatedEvent(User user) {
this.user = user;
this.createdAt = LocalDateTime.now();
}
}
// 发布事件
@Service
public class UserService {
private final EventPublisher eventPublisher;
private final UserRepository userRepository;
public UserService(EventPublisher eventPublisher, UserRepository userRepository) {
this.eventPublisher = eventPublisher;
this.userRepository = userRepository;
}
public User create(User user) {
User saved = userRepository.save(user);
// 发布事件
eventPublisher.publishEvent(new UserCreatedEvent(saved));
return saved;
}
}
// 监听事件
@Component
public class UserEventListener {
private final EmailService emailService;
public UserEventListener(EmailService emailService) {
this.emailService = emailService;
}
// 同步监听
@EventListener
public void onUserCreated(UserCreatedEvent event) {
log.info("用户创建: {}", event.getUser().getUsername());
}
// 异步监听
@Async
@EventListener
public void sendWelcomeEmail(UserCreatedEvent event) {
emailService.sendWelcomeEmail(event.getUser());
}
// 事务监听(事务提交后执行)
@TransactionalEventListener
public void syncToSearchEngine(UserCreatedEvent event) {
// ...同步数据到搜索引擎
}
}
