Question

我正在使用hibernate-entity-generator（maven插件）从数据库表生成实体类。

生成实体中的所有数据类型都是对象类型，如何让hibernate生成主要类型而不是对象类型？

例如，我有一个user_data_profile表（mysql）：

+--------------------+------------+
| Field              | Type       |
+--------------------+------------|
| id                 | bigint(20) |
| login_times        | int(11)    |
| work_apply_times   | int(11)    |
| work_done_times    | int(11)    |
+--------------------+------------+

生成的实体类如下：

public class UserDataProfile {
    private Long id;
    private Integer loginTimes;
    private Integer workApplyTimes;
    private Integer workDoneTimes;
}

我真正想要的是：

public class UserDataProfile {
    private long id;
    private int loginTimes;
    private int workApplyTimes;
    private int workDoneTimes;
}

最后我找到了解决方案，并在此处发布。希望它可以帮助别人。

要使hibernate实体生成器生成主要类型而不是包装器对象，我们需要在“hibernate-reverse-engineering”配置文件中配置类型映射。例如：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-reverse-engineering PUBLIC
        "-//Hibernate/Hibernate Reverse Engineering DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-reverse-engineering-3.0.dtd" >
<hibernate-reverse-engineering>
    <schema-selection match-schema="user"/>
    <!-- use type-mappings to mapping jdbc type and hibernate type -->
    <type-mapping>
        <sql-type jdbc-type="BIGINT" hibernate-type="long"/>
        <sql-type jdbc-type="INTEGER" hibernate-type="int"/>
    </type-mapping>
    <table schema="user" name="user">
        <primary-key>
            <key-column name="id"/>
        </primary-key>
    </table>
</hibernate-reverse-engineering>
