java - JPA、EJB 错误 HHH000262 : Table not found: employee

Question

我有一个带有 jpa 和 ejb 的简单 maven 项目，它在服务器 glassfish 4.1 上运行

我的 persistence.xml 文件是:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
    <persistence-unit name="EmployeeService" transaction-type="JTA">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
        <class>com.bkstorm.jpa.model.Employee</class>
        <properties>
            <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
            <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/jpa" />
            <property name="javax.persistence.jdbc.user" value="root" />

            <property name="hibernate.format_sql" value="true"/>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="validate"/>
            <!-- Configuring Connection Pool -->
            <property name="hibernate.c3p0.min_size" value="5"/>
            <property name="hibernate.c3p0.max_size" value="20"/>
            <property name="hibernate.c3p0.timeout" value="500"/>
            <property name="hibernate.c3p0.max_statements" value="50"/>
            <property name="hibernate.c3p0.idle_test_period" value="2000"/>
            <property name="javax.persistence.schema-generation.database.action" value="create"/>
        </properties>
    </persistence-unit>
</persistence>

我的实体文件Employee.java:

@Entity
@Table(name = "employee")
public class Employee implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "emp_id")
    private int id;
    @Column(name = "name")
    private String name;
    @Column(name = "sal")
    private int salary;

    public int getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public int getSalary() {
        return salary;
    }

    public void setSalary(int salary) {
        this.salary = salary;
    }

    @Override
    public String toString() {
        return "Employee id: " + getId() + " name: " + getName() + " salary: " + getSalary();
    }
}

我有一个 ejb session bean:员工服务.java

public interface EmployeeService {

    public Employee createEmployee(String name, int salary);

    public Collection<Employee> findAllEmployees();
}

和实现EmployeeService的EmployeeServiceBean.java

@Stateless
public class EmployeeServiceBean implements EmployeeService {

    @PersistenceContext(unitName = "EmployeeService")
    protected EntityManager em;

    @Override
    public Employee createEmployee(String name, int salary) {
        Employee emp = new Employee();
        emp.setName(name);
        emp.setSalary(salary);
        em.persist(emp);
        return emp;
    }

    @Override
    public Collection<Employee> findAllEmployees() {
        Query query = em.createQuery("SELECT e FROM Employee e");
        return (Collection<Employee>) query.getResultList();
    }

}

我不知道错误是从哪里来的。任何想法，谢谢!

更新 1:将“验证”更改为“更新”并没有解决我的问题。员工表存在于我的数据库中。当我运行 glassfish 服务器时，它显示日志:
