spring-data-jpa二級緩存(EhCache)配置

1、maven配置

<hibernate.version>5.1.4.Final</hibernate.version>

<!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-ehcache -->
        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-ehcache</artifactId>
            <version>${hibernate.version}</version>
        </dependency> 

2、配置xml

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="jpaVendorAdapter">
            <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
                <property name="showSql" value="${db.showSql}" />
                <property name="generateDdl" value="${db.generateDdl}" />
                <property name="database" value="${db.database}" />
            </bean>
        </property>
        <property name="packagesToScan">
            <list>
                <value>cn.com.easy.*.model</value>
                <value>cn.com.platform.model</value>
            </list>
        </property>
        <property name="jpaProperties">
            <props>
                <!-- 二級緩存配置 -->
                <prop key="hibernate.cache.use_query_cache">true</prop>
                <prop key="hibernate.cache.use_second_level_cache">true</prop>
                <prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop>
                <prop key="hibernate.use_sql_comments">true</prop>
                <prop key="hibernate.format_sql">false</prop>
                <prop key="hibernate.generate_statistics">true</prop>
                <prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop>
                <prop key="javax.persistence.sharedCache.mode">ENABLE_SELECTIVE</prop>
            </props>
        </property>
    </bean>

3、配置實體

@Entity
@Table(name = "pf_md_user_roles_mapping")
@DynamicInsert
@DynamicUpdate
@Cache(usage=CacheConcurrencyStrategy.TRANSACTIONAL)
public class UserRolesMappingModel extends BaseEntity {

4、配置 JpaRepository
public interface UserRolesMappingDao extends JpaRepository<UserRolesMappingModel, Long>, JpaSpecificationExecutor<UserRolesMappingModel> {
    @Query("select u from UserModel u where u.id in (select mapping.userId from UserRolesMappingModel mapping where mapping.roleId = ?1)")
    @QueryHints({@QueryHint(name = "org.hibernate.cacheable", value ="true") })
    public Page<UserModel> findUserModelByRoleId(Long roleId, Pageable pageable);
