Question

我是Spring批处理的新手。我试图使用HibernateItemWriter写入目标数据库。我在执行批处理作业时遇到异常。

以下是我的申请的例外和代码

HibernateItemWriter配置： -

@StepScope
@Bean
public ItemWriter<NewEmployee> hibernateEmployeeItemWriter() throws IOException {
        HibernateItemWriter<NewEmployee> itemWriter = new HibernateItemWriter<>();
        itemWriter.setSessionFactory(sessionFactory().getObject());
        itemWriter.setClearSession(true);
        return itemWriter;
}

会话工厂和事务管理器代码

@Bean
public LocalSessionFactoryBean sessionFactory() throws IOException{
    LocalSessionFactoryBean factoryBean = new LocalSessionFactoryBean();
    factoryBean.setDataSource(configuration.getDataSource());
   // factoryBean.setAnnotatedPackages("com.qiwkreport.qiwk.etl.domain");
    factoryBean.setPackagesToScan("com.qiwkreport.qiwk.etl.domain");
    factoryBean.afterPropertiesSet();
    return factoryBean;
}


@Bean
public JpaTransactionManager transactionManager() {
    JpaTransactionManager jpaTransactionManager = new JpaTransactionManager();
    return jpaTransactionManager;
}

实体类代码： -

    Entity
    @Table(name = "NEWEMPLOYEE")
    public class NewEmployee {

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "ID")
private long id;
@Column(name = "FIRSTNAME")
private String firstName;
@Column(name = "LASTNAME")
private String lastName;
@Column(name = "VILLAGE")
private String village;
@Column(name = "STREET")
private String street;
@Column(name = "CITY")
private String city;
@Column(name = "DISTRICT")
private String district;
@Column(name = "STATE")
private String state;
@Column(name = "PINCODE")
private String pincode;
@Column(name = "MANAGERID")
private String managerid;
@Column(name = "MANAGERNAME")
private String managerName;

在批量发布时，它仍然包含JDBC语句 - HibernateItemWriter
