Question

我有一个应用程序将ejb模块打包到一个ear文件中。当我想部署到Wildfly时，我得到以下错误。根据{{3}}帖子，standalone.xml文件不行。我检查过我的，很好。

有人可以告诉我这里可能出现什么问题吗？

的persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">
    <persistence-unit name="PU" transaction-type="JTA">
        <jta-data-source>jdbc:postgresql://localhost:5432/Database</jta-data-source>
        <properties>
            <property name="hibernate.connection.username" value="postgres"/>
            <property name="hibernate.connection.password" value="postgres" />
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.format_sql" value="true"/>
            <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQL95Dialect"/>
        </properties>
    </persistence-unit>
</persistence>

“jta-data-source指向此持久性单元映射到的数据库的JNDI名称。”来自链接https://docs.jboss.org/jbossas/docs/Server_Configuration_Guide/4/html/ch01s02s01.html

但您已经配置了connection-url。可以从jboss管理页面配置数据源，也可以通过修改独立文件来配置数据源。一个例子 - https://developer.jboss.org/wiki/JBossAS7-DatasourceConfigurationForPostgresql?_sscc=t

为什么Wildfly 10给了我＆＃34; jdbc不允许使用空名称段：postgresql＆＃34;在部署？
