java - 使用 postgresql 连接到 Wildfly 上的数据库时出现问题

Question

我在使用 postgresql 连接到 Wildfly 上的数据库时遇到问题，并且在 Red Hat Core Studio 中编写。
我的standalone.xml是:

<datasources>
         <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true" statistics-enabled="${wildfly.datasources.statistics-enabled:${wildfly.statistics-enabled:false}}">
         <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url>
              <driver>h2</driver>
              <security>
                   <user-name>sa</user-name>
                   <password>sa</password>
              </security>
          </datasource>
          <datasource jndi-name="java:jboss/datasources/tvTutorial" pool-name="tvTutorial" enabled="true" statistics-enabled="true">
               <connection-url>jdbc:postgresql//localhost:5432/tvTutorial</connection-url>
               <driver-class>org.postgresql.Driver</driver-class>
               <connection-property name="url">
                   jdbc:postgresql//localhost:5432/tvTutorial
               </connection-property>
               <driver>NewPestsList-1.0.war</driver>
               <security>
                   <user-name>user</user-name>
                   <password>password</password>
               </security>
           <validation>
               <valid-connection-checker class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLValidConnectionChecker"/>
                   <background-validation>true</background-validation>
                   <exception-sorter class-name="org.jboss.jca.adapters.jdbc.extensions.postgres.PostgreSQLExceptionSorter"/>
            </validation>
            </datasource>
            <drivers>
                <driver name="h2" module="com.h2database.h2">
                    <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
                </driver>
            </drivers>
        </datasources>
    </subsystem>
...
    </deployment>
    </deployments>
</server>

我的 persistence.xml 是:

<!DOCTYPE xml>
<persistence version="2.1"
    xmlns="http://xmlns.jcp.org/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <persistence-unit name="NewPestsList">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <properties>
            <property name='javax.persistence.jdbc.driver'
                value='org.postgresql.Driver' />
            <property name='javax.persistence.jdbc.url'
                value='jdbc:postgresql//localhost:5432/tvTutorial' />
            <property name='javax.persistence.jdbc.user'
                value='user' />
            <property name='javax.persistence.jdbc.password'
                value='password' />

            <property name='hibernate.connection.shutdown' value='true' />
            <property name='hibernate.show_sql' value='false' />

                value="false" />
        </properties>
    </persistence-unit>
</persistence>

当我进入wildfly HAL管理时

console/configuration/subsystems/datasources&drivers/JDBC Drivers/

我看到两个 JDBC 驱动程序:

"NewPestsList-1.0.war"和"NewPestsList-1.0.war_org.postgresql.Driver_42_2"如图所示 two war files我的日志是:

我感觉这与此有关，但由于我是编程新手，我不确定是否应该添加更多数据，请告诉我。

编辑:我在 stdunbar 和 Will T 的帮助下更新了我的程序。仍需学习如何重新安装 Wildfly。现在我收到这些警告和错误:

        "jboss.persistenceunit.\"NewPestsList-1.0.war#tvTutorialPU\" is missing [jboss.naming.context.java.jdbc.tvTutorial]"

编辑#2:

在我写了正确的地址后它就起作用了 <jta-data-source>jdbc/tvTutorial</jta-data-source>谢谢两位

Answer 1

diver必须作为模块添加，你不能引用你的war部署

本指南适用于 mysql，但过程是相同的，只需使用正确的名称
