أحاول تحميل بعض السياق من آر إس إس وتمريرها كذاكرة تخزين مؤقت للعميل باستخدام مكتبة إهكاش في الربيع.هنا هو رمز بلدي :
import org.springframework.cache.annotation.Cacheable;
@Service
public class GlossaryReaderService {
@Cacheable(value = "glossaryList")
public List<Glossary> readGlossary(String url) {
XmlReader reader = null;
List<Glossary> extractedGlossay = new ArrayList<Glossary>();
SyndEntry entry;
SyndContent desc;
Glossary glossaryList = null;
try {
String decodedURL = URLDecoder.decode(url, "UTF-8");
reader = new XmlReader(new URL(decodedURL));
SyndFeed feed = new SyndFeedInput().build(reader);
for (Iterator i = feed.getEntries().iterator(); i.hasNext();) {
entry = (SyndEntry) i.next();
desc = entry.getDescription();
if (desc != null) { ...
extractedGlossay.add(glossaryList);
}
}
}
} catch (IOException | IllegalArgumentException | FeedException e) {
log.error("Error reading RSS feed", e);
} finally {
IOUtils.closeQuietly(reader);
}
return extractedGlossay;
}
أيضا تحت أت / ويبمي / سرك / الرئيسية / الموارد / إهكاش.شمل لدي إيشاهي.شمل :
<?xml version="1.0" encoding="UTF-8"?>
<ehcache>
<defaultCache maxElementsInMemory="500" eternal="true"
overflowToDisk="false" memoryStoreEvictionPolicy="LFU" />
<cache name="info" maxElementsInMemory="500" eternal="true"
overflowToDisk="false" memoryStoreEvictionPolicy="LFU" />
</ehcache>
ولكن المشكلة هي أنه عندما أريد أن أضيف الفاصوليا في محتوى التطبيق أنه يعطي خطأ.هنا هو تطبيق بارتين-المحتوى.شمل :
<!-- CACHE CONFIGURATION -->
<cache:annotation-driven />
<bean id="cacheManager"
class="org.springframework.cache.ehcache.EhCacheCacheManager"
p:cache-manager-ref="ehcache" />
<bean id="ehcache class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" p:config location="classpath:ehcache.xml" />
ولكن تعطيني الخطأ التالي:

لقد كنت أعمل على هذا طوال اليوم ، لكنني لا أعرف ما هي المشكلة.من فضلك إذا كان أي شخص يعرف الجواب ، مساعدة !!!
تحرير: لقد أضفت دعم الربيع ، وهنا هو التبعيات في بوم :
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>4.0.1.RELEASE</version>
</dependency>
<!-- Ehcache -->

المحلول
يقع هذا الفصل في spring-context-support وحدة اختيارية.يرجى التأكد من أنك قمت بإضافته كتبعية لمشروعك.
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>X.Y.Z.RELEASE</version>
</dependency>
نصائح أخرى
تكوين الربيع الخاص بك ممتاز، أرى أمثلة مع الكثير من الأخطاء المطبعية على الويب.
giveacodicetagpre.ملاحظة: تحتاج إلى كل من التبعيات:
giveacodicetagpre.أول واحد هو التنفيذ الثاني هو المجمع الربيع حوله.إذا لم تستخدم كلاهما سيكون لديك استثناءات متعلقة بإيجاد الفئة المنفذة.
استخدم أدناه تبعية Maven في Pom.xml
giveacodicetagpre.أيضا، تأكد من استخدام الإصدار 4.3.4.لا تستخدم 5.0.6 وغيرها من أحدث إصدار، لم يعمل بالنسبة لي.
