Question

我有一个使用两个数据源的Spring boot + Spring数据JPA应用程序。我已经使用LocalContainerEntityManagerFactoryBean配置了实体管理器，如下所示：

#include <stdio.h>

int main(void)
{
    printf("Hello World\n");
    printf("Press the Enter key to continue\n");
    (void) getc(stdin);
    return 0;
}

这对我来说很好。 为两个数据源添加缓存 然后我想为此添加memcached。我将属性添加到setJpaPropertyMap。 但是我仍然得到错误hibernate.cache.region.factory_class没有给出

我设置了以下属性：

 @Bean
    @Primary
    public LocalContainerEntityManagerFactoryBean userEntityManager() {
        LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
        em.setDataSource(userDataSource());
        em.setPackagesToScan(new String[] { "uk.co.o2.smip.validator.dao.entity.user" });
        em.setSharedCacheMode(SharedCacheMode.ALL);
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();

        em.setJpaVendorAdapter(vendorAdapter);
        HashMap<String, Object> properties = new HashMap<String, Object>();
        properties.put("hibernate.hbm2ddl.auto", "validate");
        properties.put("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
        em.setJpaPropertyMap(properties);

我已经检查过类路径中提到的类文件。不知道什么是错的。

例外

properties.put("spring.jpa.properties.hibernate.cache.use_second_level_cache", "true");
    properties.put("spring.jpa.properties.hibernate.cache.use_query_cache", "true");
    properties.put("spring.jpa.properties.hibernate.cache.region.factory_class", "kr.pe.kwonnam.hibernate4memcached.Hibernate4MemcachedRegionFactory");
    properties.put("spring.jpa.properties.hibernate.cache.default_cache_concurrency_strategy", "NONSTRICT_READ_WRITE");
    properties.put("spring.jpa.properties.hibernate.cache.region_prefix", "validatorCache");
    properties.put("spring.jpa.properties.hibernate.cache.use_structured_entries", "false");
    properties.put("spring.jpa.properties.h4m.adapter.class", "kr.pe.kwonnam.hibernate4memcached.spymemcached.SpyMemcachedAdapter");
    properties.put("spring.jpa.properties.h4m.timestamper.class", "kr.pe.kwonnam.hibernate4memcached.timestamper.HibernateCacheTimestamperMemcachedImpl");

    properties.put("spring.jpa.properties.h4m.adapter.spymemcached.hosts", "localhost:11211");
    properties.put("spring.jpa.properties.h4m.adapter.spymemcached.hashalgorithm", "KETAMA_HASH");
    properties.put("spring.jpa.properties.h4m.adapter.spymemcached.operation.timeout.millis", "5000");
    properties.put("spring.jpa.properties.h4m.adapter.spymemcached.transcoder", "kr.pe.kwonnam.hibernate4memcached.spymemcached.KryoTranscoder");
    properties.put("spring.jpa.properties.h4m.adapter.spymemcached.cachekey.prefix", "validator");
    properties.put("spring.jpa.properties.h4m.adapter.spymemcached.kryotranscoder.compression.threashold.bytes", "20000");


    properties.put("spring.jpa.properties.h4m.expiry.seconds", "600");

    properties.put("spring.jpa.properties.h4m.expiry.seconds.validatorCache.org.hibernate.cache.spi.UpdateTimestampsCache", "86400");

    properties.put("spring.jpa.properties.h4m.expiry.seconds.validatorCache.org.hibernate.cache.internal.StandardQueryCache", "3600");


   // properties.put("spring.jpa.properties.h4m.expiry.seconds.validatorCache.certificates", "1800");
    properties.put("spring.jpa.properties.h4m.expiry.seconds.validatorCache.users", "1800");

使用Spring进行Memcached，因为多个数据源无法正常工作
