Question

我正在使用Wildfly 8.2.1，我尝试将我的EAR项目部署到Wildfly。

一切正常，但由于我更改了数据库架构并通过 JPA-Tools 生成了新的实体类，因此出现错误。

这是我的persistence.xml（我在那里没有改变）：

<?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="PrototypeShitstormRecEJB">
        <jta-data-source>java:jboss/datasources/ShitstormDS</jta-data-source>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
            <property name="hibernate.hbm2ddl.auto" value="create"/>
            <property name="hibernate.show_sql" value="true"/>
        </properties>
    </persistence-unit>
</persistence>

此处console登录部署： ...

非常感谢您的帮助：）

Answer 1

非常感谢。在错误日志中，它对我来说有点隐藏：

Duplicate query mapping GETALL

我有两个同名的NamedQueries＆＃34; GETALL＆＃34;。
