0. 最近感觉 “困意驱动睡眠” 也有他的意义
spring cache学习（一）：spring cache注解简单了解
Java Caching JSR107介绍
同样，本章也会简单的集成redisson作为缓存服务
1. 从我们自己写的javaConfig开始吧
@Configuration
// 这块依赖只是为了先初始化 RedissonClient
@ConditionalOnClass(DemoRedissonConfiguration.class)
@DependsOn(value = "demoRedissonConfiguration")
@EnableCaching
// spring.cache 提供了 configurer 的方式暴露可配置的接入点
public class DemoCacheConfiguration extends CachingConfigurerSupport {
private RedissonClient redissonClient;
@Autowired(required = false)
public void setRedissonClient(RedissonClient redissonClient) {
this.redissonClient = redissonClient;
}
@Bean
@Override
public KeyGenerator keyGenerator() {
return new KeyGenerator() {
/**
* 返回key
* @param target 包名
* @param method 方法名
* @param params 参数
* @return key 缓存密钥
*/
@Override
public Object generate(Object target, Method method, Object... params) {
StringBuilder sb = new StringBuilder();
//拼接字符串
sb.append(target.getClass().getName());
sb.append(method.getName());
sb.append("(");
for (Object obj : params) {
if (obj == null) {
continue;
}
sb.append(obj.toString());
sb.append(",");
}
sb.deleteCharAt(sb.length() - 1);
sb.append(")");
return sb.toString();
}
};
}
// Redisson 分布式缓存实现
// @Primary
// @Bean
// @ConditionalOnClass({RedissonClient.class})
// @Override
// public CacheManager cacheManager() {
// Map<String, CacheConfig> config = Maps.newHashMap();
// Arrays.stream(CacheEnum.values()).filter(Objects::nonNull).forEach(var -> {
// String cacheName = var.getName();
// cn.angel.boot.demo.cache.CacheConfig cacheConfig = var.getConfig();
// CacheConfig redissonCacheConfig = new CacheConfig(cacheConfig.getExpireInSec(), cacheConfig.getExpireInSec());
// config.put(cacheName, redissonCacheConfig);
// });
// return new RedissonSpringCacheManager(this.redissonClient, config);
// }
// Caffeine JVM缓存实现
@Bean
@Override
public CacheManager cacheManager() {
SimpleCacheManager cacheManager = new SimpleCacheManager();
List<CaffeineCache> caches = Arrays.stream(CacheEnum.values()).filter(Objects::nonNull).map(var -> {
String cacheName = var.getName();
CacheConfig cacheConfig = var.getConfig();
return new CaffeineCache(cacheName,
Caffeine
.newBuilder()
.initialCapacity(cacheConfig.getInitialCapacity())
.maximumSize(cacheConfig.getMaximumSize())
.expireAfterWrite(cacheConfig.getExpireInSec(), TimeUnit.SECONDS)
.build());
}).collect(Collectors.toList());
cacheManager.setCaches(caches);
return cacheManager;
}
}
1.1 补充:spring.context.no-lazy.@Bean的初始化
-
其实跟普通的bean初始化的位置是一样的
-
@Configuration.ProxyBeanMethod设为false，将不会走BeanMethodInterceptor
- 此时调用其下的bean工厂方法将会产生一个实例，并不会优先从池中查找，这点需要注意
- 这么做的好处即，少走一步，提升初始化的性能
// 我们自己的配置类
cacheManager:94, DemoCacheConfiguration (cn.angel.boot.demo.cache)

invokeSuper:244, MethodProxy (org.springframework.cglib.proxy)
// @Configuration(proxyBeanMethods默认true)就会走这里
intercept:331, ConfigurationClassEnhancer$BeanMethodInterceptor (org.springframework.context.annotation)

finishBeanFactoryInitialization:879, AbstractApplicationContext (org.springframework.context.support)
refresh:551, AbstractApplicationContext (org.springframework.context.support)
1.2 补充:configurer范式
-
相比于 Customizer 的扩展方法，我还是更喜欢 configurer的方式
-
spring.function.SingletonSupplier 是个函数式接口，impls j.u.Function
- 这也是configurer 扩展模式的"奥秘"，即借助函数式接口延迟执行，随取随用
看下我们对configurer中CacheManager的实现方法，在哪里被访问
cacheManager:72, DemoCacheConfiguration (cn.angel.boot.demo.cache)
get:-1, 497333241 (org.springframework.cache.annotation.AbstractCachingConfiguration$$Lambda$361)
resolve:40, SupplierUtils (org.springframework.util.function)
// 简单来说就是 CacheResolver 委托了 CacheManager
// CacheResolver 帮助 CacheManager 利用cache的cacheName

finishBeanFactoryInitialization:879, AbstractApplicationContext (org.springframework.context.support)
refresh:551, AbstractApplicationContext (org.springframework.context.support)
2. spring.cache 相关注解的元信息解析
这个也是发生在程序启动过程中的,准确的来说，是在AbstractAutoProxyCreator.postProcessAfterInitialization这个阶段
CacheOperation即我们使用的spring.cache 或 javax.caching(spring中称之为JCache) 注解被解析后的元信息CacheOperationSource用于引导CacheOperation初始化的
// 这玩意用来解析 cache 相关的注解的

注解的解析逻辑
// org.springframework.cache.annotation.SpringCacheAnnotationParser.java
// 被注解的Method -> CacheConfig
@Override
@Nullable
public Collection<CacheOperation> parseCacheAnnotations(Method method) {
DefaultCacheConfig defaultConfig = new DefaultCacheConfig(method.getDeclaringClass());
return parseCacheAnnotations(defaultConfig, method);
}
@Nullable
private Collection<CacheOperation> parseCacheAnnotations(DefaultCacheConfig cachingConfig, AnnotatedElement ae) {
Collection<CacheOperation> ops = parseCacheAnnotations(cachingConfig, ae, false);
if (ops != null && ops.size() > 1) {
// More than one operation found -> local declarations override interface-declared ones...
Collection<CacheOperation> localOps = parseCacheAnnotations(cachingConfig, ae, true);
if (localOps != null) {
return localOps;
}
}
return ops;
}
@Nullable
private Collection<CacheOperation> parseCacheAnnotations(
DefaultCacheConfig cachingConfig, AnnotatedElement ae, boolean localOnly) {
Collection<? extends Annotation> anns = (localOnly ?
AnnotatedElementUtils.getAllMergedAnnotations(ae, CACHE_OPERATION_ANNOTATIONS) :
AnnotatedElementUtils.findAllMergedAnnotations(ae, CACHE_OPERATION_ANNOTATIONS));
if (anns.isEmpty()) {
return null;
}
// 就这几个cache注解
final Collection<CacheOperation> ops = new ArrayList<>(1);
anns.stream().filter(ann -> ann instanceof Cacheable).forEach(
ann -> ops.add(parseCacheableAnnotation(ae, cachingConfig, (Cacheable) ann)));
anns.stream().filter(ann -> ann instanceof CacheEvict).forEach(
ann -> ops.add(parseEvictAnnotation(ae, cachingConfig, (CacheEvict) ann)));
anns.stream().filter(ann -> ann instanceof CachePut).forEach(
ann -> ops.add(parsePutAnnotation(ae, cachingConfig, (CachePut) ann)));
anns.stream().filter(ann -> ann instanceof Caching).forEach(
ann -> parseCachingAnnotation(ae, cachingConfig, (Caching) ann, ops));
return ops;
}
// cacheConfig -> CacheOperation
private CacheableOperation parseCacheableAnnotation(
AnnotatedElement ae, DefaultCacheConfig defaultConfig, Cacheable cacheable) {
CacheableOperation.Builder builder = new CacheableOperation.Builder();
builder.setName(ae.toString());
builder.setCacheNames(cacheable.cacheNames());
builder.setCondition(cacheable.condition());
builder.setUnless(cacheable.unless());
builder.setKey(cacheable.key());
builder.setKeyGenerator(cacheable.keyGenerator());
builder.setCacheManager(cacheable.cacheManager());
builder.setCacheResolver(cacheable.cacheResolver());
builder.setSync(cacheable.sync());
defaultConfig.applyDefault(builder);
CacheableOperation op = builder.build();
validateCacheOperation(ae, op);
return op;
}
AnnotationCacheOperationSource 内部维护了 SpringCacheAnnotationParser
CacheOperationSource 引导了 CacheOperation 的初始化
3. 接入 spring.expression
这块解析 spel表达式肯定是发生在运行过程中的
parseExpression:43, TemplateAwareExpressionParser (org.springframework.expression.common)
getExpression:89, CachedExpressionEvaluator (org.springframework.context.expression)
key:104, CacheOperationExpressionEvaluator (org.springframework.cache.interceptor)
// 接入 spring.expression

4. 接入 aop
-
spring.cache 整合了 javax.caching(JCache)、spring 两种风格
-
javax.caching 是一套规范，而非实现，redisson支持了其实现
-
javax.caching 支持 进程层面的缓存、分布式缓存,通过声明(注解)使用
