Spring-Hibernate-mvc自动表创建失败

时间：2017-03-14 06:35:33

标签： java spring hibernate model-view-controller

即使数据库存在于后端......在执行spring-hibernate-cf文件时，它会导致以下异常......

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException：表＆＃39; school.customer＆＃39;不存在

注意：我没有使用H2 DB BUILDER ..

以下是我的Customer.java pojo：

    package org.springsource.cloudfoundry.mvc.services;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.validation.constraints.NotNull;
import java.io.Serializable;
import java.util.Date;

@Entity
public class Customer implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;

@NotNull
private Date signupDate;

@NotNull
private String firstName;

@NotNull
private String lastName;

public Integer getId() {
    return id;
}

public void setId(Integer id) {
    this.id = id;
}

public String getFirstName() {
    return firstName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
}

public String getLastName() {
    return lastName;
}

public void setLastName(String lastName) {
    this.lastName = lastName;
}

public Date getSignupDate() {
    return signupDate;
}

public void setSignupDate(Date signupDate) {
    this.signupDate = signupDate;
}
}

以下是CustomerService.java：

     package org.springsource.cloudfoundry.mvc.services;

  import org.springframework.cache.annotation.Cacheable;
  import org.springframework.stereotype.Service;

    Customer customer = new Customer();
    customer.setFirstName(firstName);
    customer.setLastName(lastName);
    customer.setSignupDate(signupDate);
    em.persist(customer);
    return customer;
 }

 public Collection<Customer> search(String name) {
    String sqlName = ("%" + name + "%").toLowerCase();
    String sql = "select c.* from customer c where (LOWER( c.firstName ) LIKE :fn OR LOWER( c.lastName ) LIKE :ln)";
    return em.createNativeQuery(sql, Customer.class)
            .setParameter("fn", sqlName)
            .setParameter("ln", sqlName)
            .getResultList();
        }


 @Transactional(readOnly = true)
 public List<Customer> getAllCustomers() {
    return em.createQuery("SELECT * FROM " +   Customer.class.getName()).getResultList();
  }


@Cacheable(CUSTOMERS_REGION)
@Transactional(readOnly = true)
public Customer getCustomerById(Integer id) {
    return em.find(Customer.class, id);
}

@CacheEvict(CUSTOMERS_REGION)
public void deleteCustomer(Integer id) {
    Customer customer = getCustomerById(id);
    em.remove(customer);
}

@CacheEvict(value = CUSTOMERS_REGION, key = "#id")
public void updateCustomer(Integer id, String fn, String ln, Date birthday)         {
    Customer customer = getCustomerById(id);
    customer.setLastName(ln);
    customer.setSignupDate(birthday);
    customer.setFirstName(fn);
    //sessionFactory.getCurrentSession().update(customer);
    em.merge(customer);
    }
   }

我认为问题是你在这里使用H2Dialect连接到MySQL数据库：

p.put(org.hibernate.cfg.Environment.DIALECT, H2Dialect.class.getName());
