1. sessionFactory 的配置

@Configuration
//啟用註解事務管理,使用CGLib代理
@EnableTransactionManagement(proxyTargetClass = true)
@Import({DataSourceConfig.class})
public class DaoConfig {

    private static final Logger logger = Logger.getLogger(DaoConfig.class);
    @Resource(name = "dataSource")
    public DataSource dataSource
 
;
    @Value("${hibernate.dialect}")
    String hibernate_dialect;
    @Value("${hibernate.show_sql}")
    String hibernate_show_sql;

    /**
     * 描述 : <負責解析資原始檔>. <br>     * <p>     * <這個類必須有,而且必須宣告為static,否則不能正常解析>
     * </p>     *
     * @return
*/
@Bean
public static 
 
PropertySourcesPlaceholderConfigurer placehodlerConfigurer() {
        logger.info("PropertySourcesPlaceholderConfigurer");
        return new PropertySourcesPlaceholderConfigurer();
    }

    @Bean(name = "hibernateDAO")
    public CP_Hibernate4DAOImpl hibernate4Dao() {
        logger.info("hibernateDAO"
 
);
        CP_Hibernate4DAOImpl dao = new CP_Hibernate4DAOImpl();
        dao.setSessionFactory(localSessionFactoryBean().getObject());
        return dao;
    }

    @Bean(name = "sessionFactory")
    public LocalSessionFactoryBean localSessionFactoryBean() {
        logger.info("sessionFactory");
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource);
        String[] packagesToScan = new String[]{"com.mvc.entity"};
        sessionFactory.setPackagesToScan(packagesToScan);

        Properties hibernateProperties = new Properties();
        hibernateProperties.setProperty("hibernate.dialect", hibernate_dialect);
        hibernateProperties.setProperty("hibernate.show_sql",
            hibernate_show_sql);
        hibernateProperties.setProperty(
            "hibernate.current_session_context_class",
            "org.springframework.orm.hibernate5.SpringSessionContext");
        // 二級快取
hibernateProperties.setProperty("hibernate.cache.use_second_level_cache", "true");
        hibernateProperties.setProperty("hibernate.cache.use_query_cache", "true");
//        hibernateProperties.setProperty("hibernate.cache.provider_class",
//                "org.hibernate.cache.EhCacheProvider");
//        hibernateProperties.setProperty("hibernate.cache.region.factory_class",
//                "org.hibernate.cache.ehcache.EhCacheRegionFactory");
hibernateProperties.setProperty("hibernate.cache.region.factory_class",
                "org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory");


        sessionFactory.setHibernateProperties(hibernateProperties);

        return sessionFactory;

    }

2. datasource配置

@Configuration
//db 配置檔案
@PropertySource({"classpath:config/properties/db.properties"})
public class DataSourceConfig {
    private static final Logger logger = Logger.getLogger(DataSourceConfig.class);
    /*
     *db 配置
     */
@Value("${jdbc.driver}")
    String driverClass;
    @Value("${jdbc.url}")
    String url;
    @Value("${jdbc.username}")
    String userName;
    @Value("${jdbc.password}")
    String passWord;

    @Bean(name = "dataSource")
    public DataSource dataSource() {
        logger.info("DataSource");
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(driverClass);
        dataSource.setUrl(url);
        dataSource.setUsername(userName);
        dataSource.setPassword(passWord);
        return dataSource;
    }
}

//  ehcache 配置配置

@Configuration
@EnableCaching//<!-- 啟用快取註解 --> <cache:annotation-driven cache-manager="cacheManager" />
public class CachingConfig {
    private static final Logger logger = Logger.getLogger(CachingConfig.class);


    @Bean
public EhCacheManagerFactoryBean ehCacheManagerFactoryBean() {
        EhCacheManagerFactoryBean ehCacheManagerFactoryBean = new EhCacheManagerFactoryBean();
        ehCacheManagerFactoryBean.setConfigLocation(new ClassPathResource(
            "config/ehcache.xml"));
        ehCacheManagerFactoryBean.setShared(true);
        return ehCacheManagerFactoryBean;
    }

    @Bean
public CacheManager cacheManager() {
        logger.info("EhCacheCacheManager");
        EhCacheCacheManager cacheManager = new EhCacheCacheManager();
        cacheManager.setCacheManager(ehCacheManagerFactoryBean().getObject());
        return cacheManager;
    }
}

@Entity
@Table(name="UserInfo")
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
public class UserInfo {

1 . Unable to create requested service [org.hibernate.cache.spi.RegionFactory]

原因： hibernate.cache.region.factory_class 屬性沒有配置， 這個屬於hibernate版本4以上的配置, 3版本配置 hibernate.cache.provider_class

2. Another unnamed CacheManager already exists in the same VM.

原因  ehcache在2.5以後，CacheManager使用了Singleton，這樣在建立多個CacheManager時就會產生上述錯誤。ehCacheManagerFactoryBean.setShared(true);

於是我嘗試找到ehcache2.5 以前的jar包進行嘗試，對於gradle 自動下載compile("org.hibernate:hibernate-ehcache:5.1.7.Final") 自動下載hibernate依賴會連

同ehcache也自動關聯一個版本， 所以使用本地jar載入，建立src 同級目錄，在build.gradle 中新增 compile fileTree(dir:'libs',include:['*.jar'])， 去掉ehCacheManagerFactoryBean.setShare(true),

同時還要載入 
    compile("org.apache.logging.log4j:log4j-core:2.8.2")
    compile("log4j:log4j:1.2.17")

這兩個日誌依賴，才能正常執行
