Hyperjaxb 3导入了XSD和persistence.xml

Question

这是我第一次尝试使用Hyperjaxb3。我有一个2 XSD的片段，如下所示

ContractFullInfo.xsd

<xsd:import namespace="http://homecredit.net/homerselect/common/v1" schemaLocation="Common.xsd"/>
<xsd:element name = "ContractFullInfoRequest">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="systemEvent" type="common:ContractSystemEventType"/>
<xsd:element name="data" type="ContractFullInfo"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
<xsd:complexType name="ContractPerson">
<xsd:sequence>
<xsd:element name="cuid" type="xsd:long"/>
<xsd:element name="personRole" type="PersonRoleType"/>
</xsd:sequence>
</xsd:complexType>

Common.xsd

<xsd:complexType name="ContractPerson">
<xsd:sequence>
<xsd:element name="cuid" type="xsd:long"/>
<xsd:element name="personRole" type="PersonRoleType"/>
</xsd:sequence>
</xsd:complexType>

这个问题产生了两个ContractPerson类，如下所示：

<class>net.homecredit.homerselect.common.v1.ContractPerson</class> <==
<class>net.homecredit.homerselect.common.v1.MoneyDto</class>
<class>net.homecredit.homerselect.contract.v3.BankAccount</class>
<class>net.homecredit.homerselect.contract.v3.ClosedEndParameter</class>
<class>net.homecredit.homerselect.contract.v3.ContractBase</class>
<class>net.homecredit.homerselect.contract.v3.ContractCommodity</class>
<class>net.homecredit.homerselect.contract.v3.ContractDocument</class>
<class>net.homecredit.homerselect.contract.v3.ContractEvent</class>
<class>net.homecredit.homerselect.contract.v3.ContractFullInfo</class>
<class>net.homecredit.homerselect.contract.v3.ContractFullInfoRequest</class>
<class>net.homecredit.homerselect.contract.v3.ContractParameter</class>
<class>net.homecredit.homerselect.contract.v3.ContractPerson</class> <==
<class>net.homecredit.homerselect.contract.v3.ContractService</class>
<class>net.homecredit.homerselect.contract.v3.RefinancedContract</class>
<class>net.homecredit.homerselect.contract.v3.RevolvingParameter</class>

它在部署为时给了我错误

Entity name must be unique in a persistence unit. Entity name [ContractPerson] is used for the entity classes [net.homecredit.homerselect.common.v1.ContractPerson] and [net.homecredit.homerselect.contract.v3.ContractPerson].

我的Java配置的一部分(我目前对此发表了评论(

@Bean
public DataSource dataSource() throws NamingException {
return (DataSource) new JndiTemplate().lookup(env.getProperty("spring.datasource.jndi-name"));
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() throws NamingException {
LocalContainerEntityManagerFactoryBean em
= new LocalContainerEntityManagerFactoryBean();
em.setPackagesToScan(new String[]{"net.homecredit.homerselect.contract.v3"});
em.setPersistenceUnitName("net.homecredit.homerselect.common.v1:net.homecredit.homerselect.contract.v3");
em.setJtaDataSource(dataSource());
Properties properties = new Properties();
properties.setProperty("hibernate.dialect", env.getProperty("spring.jpa.properties.hibernate.dialect"));
properties.setProperty("hibernate.hbm2ddl.auto", env.getProperty("spring.jpa.hibernate.ddl-auto"));
em.setJpaProperties(properties);
return em;
}

我的问题：

1. 两个类完全相同。我该怎么选
2. 我使用的是Spring Boot，有没有一种方法可以使用Spring Boot java配置来覆盖persistence.xml

Answer 1

您的类不同，因为您的模式中有两种不同的复杂类型。它们可能还引用了不同的PersonRoleType，但很难说没有看到完整的模式。

虽然将这些复杂类型映射到同一个Java类上并非不可能，但我不会这么做。这些类型在您的模式中是不同的类型，您也应该在Java中保持它们的不同。

由于类具有相同的本地名称会遇到问题，因此最简单的解决方案是重命名其中一个。使用类似的绑定
