类广播异常休眠映射nvarchar

Question

I am trying to use DetachedCriteria to retreive Database details from the SQl server DB like below. the nvarcharID is of String Type

List<POJO> pojoObj = (List<POJO>) getHibernateTemplate().findByCriteria(DetachedCriteria.forClass(
            POJO.class).add(Restrictions.idEq(nvarcharID)));

In My POJO I have following attributes

@Id
@GeneratedValue
@Column(name = "ID")
private double ID;

@Nationalized
@Column(name = "Column1")
private String string1;

@Nationalized
@Column(name = "column2")
private String string2;

Both column1 and column 2 are of type nvarchar inSql serverDB. and nvarcharID used above in the Criteria is another field in DB which is of type nvarchar in DB and I have mapped it as String. While populating the POJO, I do not want navarcharID field to be part of my POJO.

For hibernate I have following dependencies in my gradle file

compile group: 'org.hibernate', name: 'hibernate-entitymanager', version: '4.3.11.Final'
compile group: 'javax.validation', name: 'validation-api', version: '1.0.0.GA'
compile group: 'org.hibernate', name: 'hibernate-validator-annotation-processor', version: '4.3.2.Final'
compile group: 'org.hibernate', name: 'hibernate-validator', version: '4.3.2.Final'
compile 'org.hibernate:hibernate-core:4.3.11.Final'

and my Spring dependencies are

 compile group: 'org.springframework', name: 'spring-orm', version:'4.1.6.RELEASE'
compile group: 'org.springframework', name: 'spring-webmvc', version: '4.1.6.RELEASE'
compile group: 'org.springframework.security', name: 'spring-security-web', version: '4.0.2.RELEASE'

I am also setting following properties in my Hibernate config file for Dialect and ddl operations.

   @Bean
public LocalSessionFactoryBean sessionFactoryBean() {
    LocalSessionFactoryBean localSessionFactoryBean = new LocalSessionFactoryBean();
    localSessionFactoryBean.setDataSource(dataSource);
    localSessionFactoryBean.setPackagesToScan(new String[] { "com.wk.cdi" });

    Properties properties = new Properties();
    properties.setProperty("hibernate.dialect", "org.hibernate.dialect.SQLServer2012Dialect");
    properties.setProperty("hibernate.use_nationalized_character_data", "true");
    properties.setProperty("hibernate.hbm2ddl.auto", "update");
    properties.setProperty("hibernate.format_sql", "true");
    properties.setProperty("hibernate.show_sql", "true");
    localSessionFactoryBean.setHibernateProperties(properties);
    return localSessionFactoryBean;
}

When I try to use hibernateTemplate to retreive the data I am getting java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Double and it throws the error while using DetachedCriteria ealborated above

PLease ignore this as there was something else. It happens to be that the Restrcition.idEq needed to be replaced by Restrictions.eq
