Table's schema is different with datasource's user

Hibernate ORM
1 
I have defined the schema attribute in @Table annotation of a POJO class:

@Entity
@Table(name = "EQ_REGISTER", schema = "IPARKMETADATA")
@JsonIgnoreProperties(value = { "hibernateLazyInitializer", "handler", "fieldHandler" })
public class EqTypeRegister implements Serializable {

and configured the user parameter in the db.properties:

jdbc.user=IPARKMETADATA_dleq

and related them in the spring configuration xml file:

<context:property-placeholder location="classpath:db.properties" />
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driverClass}" />
        <property name="jdbcUrl" value="${jdbc.jdbcUrl}" />
        <property name="user" value="${jdbc.user}" />
        <property name="password" value="${jdbc.password}" />
    </bean>

But it does not work.So I delete the "schema" attribute in the @Table annotation, and configure the default schema in the hibernate.cfg.xml:

<property name="Hibernate.default_schema">iParkMetaData_dleq</property>

It doesn't work as well!
Because the user IPARKMETADATA is the product's default database of Oracle,we have to copy new databases for different projects in the same instance of oracle(for example, use IPARKMETADATA_a,IPARKMETADATA_b,...e.g.),so we can't change the schema attribute value in the JavaBean class. 
So how can I solve the problem?How to map them?
