Why isn't the Bean found? (Spring 4.x EhCache 3.x, Apache Tomcat 7)

问题

Trying to add a cache to an existing Spring 4.3 (not SpringBoot) application

Using EhCache 3.5, It is confusing.

beans.xml

<bean id="ehCacheManager" class="org.springframework.cache.jcache.JCacheCacheManager">
    <property name="cacheManager">
        <bean class="org.springframework.cache.jcache.JCacheManagerFactoryBean"
              jsr107:cacheManagerUri="classpath:ehcache.xml"/>
    </property>
</bean>

MyCacheService.java

package com.me;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.jcache.JCacheCacheManager;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Component;

import java.net.URISyntaxException;

@Component
public class MyCacheService {
    private static int value = 7;

    @Cacheable("cache")
    public int incValue() {
        return value++;
    }
}

pom.xml

    <dependency>
        <groupId>org.ehcache</groupId>
        <artifactId>ehcache</artifactId>
        <version>3.5.0</version>

        <groupId>javax.cache</groupId>
        <artifactId>cache-api</artifactId>

    </dependency>

ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>

  </service>

  <cache alias="cache">
    <resources>
      <heap unit="entries">2000</heap>
    </resources>
  </cache>
</config>

in a class,

@Autowired
MyCacheService myCacheService;

in a method if the class,

        System.out.println("FOO -------------" + myCacheService.incValue());

UPDATE:

I changed the version of ehcache to 3.0.0

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myCacheService' defined in file [C:\Foo\target\foo-web-service\WEB-INF\classes\com\me\MyCacheService.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cache.interceptor.CacheInterceptor#0': Cannot resolve reference to bean 'ehCacheManager' while setting bean property 'cacheManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ehCacheManager': Failed to introspect bean class [org.springframework.cache.jcache.JCacheCacheManager] for lookup method metadata: could not find class that it depends on; nested exception is java.lang.NoClassDefFoundError: javax/cache/CacheManager

回答1:

The error was due to xmlns improperly defined. When I changed it to this, it was fine.

xmlns:p="http://www.springframework.org/schema/p"

and referred to it as p:

<cache:annotation-driven cache-manager="ehCacheManager"/>
<bean id="ehCacheManager" class="org.springframework.cache.jcache.JCacheCacheManager">
    <property name="cacheManager">
        <bean class="org.springframework.cache.jcache.JCacheManagerFactoryBean"
              p:cacheManagerUri="classpath:ehcache.xml"/>
    </property>
</bean>
