Eclipse - JPA EclipseLink从实体

Question

您好我正试图从eclipse中的实体生成数据库表。但它没有显示如link所示的模式生成对话框。当我点击＆＃34;从实体生成表格＆＃34;它什么都不做。

的persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
<persistence-unit name="TestEclipsLink" transaction-type="RESOURCE_LOCAL">
    <properties>
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/test"/>
        <property name="javax.persistence.jdbc.user" value="root"/>
        <property name="javax.persistence.jdbc.password" value="1234"/>
        <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver"/>
    </properties>
</persistence-unit>
</persistence>

实体类

package db.enitity;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.TableGenerator;

@Entity
@TableGenerator(name="person")
public class Person {

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int id;
private String name;


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;
}

}
