java - Spring+Hibernate配置

Question

我正在尝试集成 Spring 和 Hibernate，但是当我运行代码并提交我的 for 时，它会抛出此异常
org.springframework.dao.InvalidDataAccessResourceUsageException: could not insert: [com.xgrid.evaltask.Entities.User]; SQL [insert into User (UserName, passwd, ID) values (?, ?, ?)]; nested exception is org.hibernate.exception.SQLGrammarException: could not insert: [com.xgrid.evaltask.Entities.User]
我在谷歌上找到了原因，但卡住了
请指导我哪里错了
这是applicationcontext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

    <context:component-scan base-package="com.xgrid.evaltask"/>


    <bean id="dataSource"
             class="org.springframework.jdbc.datasource.DriverManagerDataSource"
             p:driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
             p:url="jdbc:sqlserver://DBURL:1433;databaseName=Test_DB"
             p:username="sampleUser"
             p:password="@123456asdfgh" />


     <tx:annotation-driven transaction-manager="transactionManager" />


 <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
       p:dataSource-ref="dataSource"      
       p:packagesToScan="com.xgrid.evaltask"

    <context:annotation-config />

    <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"
       p:sessionFactory-ref="sessionFactory" />

</beans>

这是 hibernate.cfg.xml
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
<!-- Enable this to see the SQL statements in the logs-->
<property name="show_sql">true</property>
<!-- This will drop our existing database and re-create a new one.
Existing data will be deleted! -->
<property name="hbm2ddl.auto">create</property>
</session-factory>
</hibernate-configuration>
这是我的 DAO 类

@Repository("authorizeDao")
public class AuthorizeDaoImpl implements AuthorizeDao {

    @Autowired
    HiberAdd hiberAdd;

    @Override
    public boolean doAuthorize(Authentication authentication) {
        System.out.println("Name: " + authentication.getUserName());
        System.out.println("PW: " + authentication.getPassWord());
        User user = new User();
        user.setId(1212);
        user.setName(authentication.getUserName());
        user.setPasswd(authentication.getPassWord());
        hiberAdd.add(user);
        return true;
    }
}

这是我的 CRUD 类

`@Service("hiberAdd")
@Transactional
public class HiberAdd {

     @Resource(name="sessionFactory")
 private SessionFactory sessionFactory;
     public void add(User user) {


  // Retrieve session from Hibernate
  Session session = sessionFactory.getCurrentSession();

  // Save
        session.save(user);
         System.out.println("Saved ......................... ");
 }
}`

这是我的实体类

`@Entity
@Table(name="User")
public class User implements Serializable{

    @Id
    @Column(name="ID")
    private Integer id;

    @Column(name="UserName")
    private String name;

    @Column(name="passwd")
    private String passwd;
//getters setters

Answer 1

USER 是 reserved keyword您的数据库。为您的表使用另一个名称。
