如何在liferay 6.2中插入数据到数据库中？

jdbc.default.driverClassName=com.mysql.jdbc.Driver
jdbc.default.url=jdbc:mysql://localhost:3306/your_database_name
jdbc.default.username=your_username
jdbc.default.password=your_password

import com.liferay.portal.kernel.model.BaseModel;
import com.liferay.portal.kernel.util.StringPool;
import com.liferay.portal.model.impl.BaseModelImpl;

public class CustomEntity extends BaseModelImpl<CustomEntity> implements BaseModel<CustomEntity> {

    private long entityId;
    private String name;

    public CustomEntity() {
    }

    public long getEntityId() {
        return entityId;
    }

    public void setEntityId(long entityId) {
        this.entityId = entityId;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

import com.liferay.portal.service.impl.BaseLocalServiceImpl;

public class CustomEntityLocalServiceImpl extends BaseLocalServiceImpl implements CustomEntityLocalService {

    public CustomEntity addCustomEntity(String name) {
        long entityId = counterLocalService.increment(CustomEntity.class.getName());
        CustomEntity customEntity = customEntityPersistence.create(entityId);
        customEntity.setName(name);
        customEntityPersistence.update(customEntity);
        return customEntity;
    }
}

<service-builder package-path="com.example">
    <entity name="CustomEntity" local-service="true" remote-service="false">
        <!-- 定义实体类字段 -->
        <column name="entityId" type="long" primary="true" />
        <column name="name" type="String" />
    </entity>
</service-builder>

ant build-service
