Question

我试图在终端上运行我的服务。它几乎没问题，只是在谷歌的大量研究之后仍然存在缺失的默认数据源错误。让我解释一下

我使用的是wildfly 10.1.0

这是我在standalone.xml中的数据源

<datasources>
    <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true">
        <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 jta="true" jndi-name="java:jboss/datasources/PostgreSQLDS" pool-name="PostgreSQLDS" enabled="true" use-java-context="true">
        <connection-url>jdbc:postgresql://localhost:5432/lucasmucida</connection-url>
        <driver>postgresql</driver>
        <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
        <pool>
            <min-pool-size>10</min-pool-size>
            <max-pool-size>100</max-pool-size>
            <prefill>true</prefill>
        </pool>
        <security>
            <user-name>xxx</user-name>
            <password>xxx</password>
        </security>
        <statement>
            <prepared-statement-cache-size>32</prepared-statement-cache-size>
            <share-prepared-statements>true</share-prepared-statements>
        </statement>
    </datasource>
    <drivers>
        <driver name="h2" module="com.h2database.h2">
            <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
        </driver>
        <driver name="postgresql" module="org.postgresql">
            <xa-datasource-class>org.postgresql.xa.PGXADataSourc</xa-datasource-class>
        </driver>
    </drivers>
</datasources>

这是包含defaul-binding

的os standalone.xml部分

<subsystem xmlns="urn:jboss:domain:ee:4.0">
                <spec-descriptor-property-replacement>false</spec-descriptor-property-replacement>
                <concurrent>
                    <context-services>
                        <context-service name="default" jndi-name="java:jboss/ee/concurrency/context/default" use-transaction-setup-provider="true"/>
                    </context-services>
                    <managed-thread-factories>
                        <managed-thread-factory name="default" jndi-name="java:jboss/ee/concurrency/factory/default" context-service="default"/>
                    </managed-thread-factories>
                    <managed-executor-services>
                        <managed-executor-service name="default" jndi-name="java:jboss/ee/concurrency/executor/default" context-service="default" hung-task-threshold="60000" keepalive-time="5000"/>
                    </managed-executor-services>
                    <managed-scheduled-executor-services>
                        <managed-scheduled-executor-service name="default" jndi-name="java:jboss/ee/concurrency/scheduler/default" context-service="default" hung-task-threshold="60000" keepalive-time="3000"/>
                    </managed-scheduled-executor-services>
                </concurrent>
                <default-bindings context-service="java:jboss/ee/concurrency/context/default" datasource="java:jboss/datasources/lucasmucida" jms-connection-factory="java:jboss/DefaultJMSConnectionFactory" managed-executor-service="java:jboss/ee/concurrency/executor/default" managed-scheduled-executor-service="java:jboss/ee/concurrency/scheduler/default" managed-thread-factory="java:jboss/ee/concurrency/factory/default"/>
            </subsystem>

这是我的module.xml，位于/ modules / system / layers / base / org / postgresql / main文件夹中

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.0" name="org.postgresql">
  <resources>
    <resource-root path="postgresql-42.1.4.jar"/>
  </resources>
  <dependencies>
     <module name="javax.api"/>
     <module name="javax.transaction.api"/>
   </dependencies>
</module>

如果我运行sh standalone.sh，它甚至会在lucasmucida数据库中创建一个表，但错误：

17:38:49,984 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("deploy") failed - address: ([("deployment" => "jpa2-1.0-SNAPSHOT.war")]) - failure description: {
    "WFLYCTL0412: Required services that are not installed:" => ["jboss.naming.context.java.jboss.datasources.lucasmucida"],
    "WFLYCTL0180: Services with missing/unavailable dependencies" => ["jboss.naming.context.java.module.\"jpa2-1.0-SNAPSHOT\".\"jpa2-1.0-SNAPSHOT\".DefaultDataSource is missing [jboss.naming.context.java.jboss.datasources.lucasmucida]"]
}
17:38:49,988 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("deploy") failed - address: ([("deployment" => "testeJava-1.0-SNAPSHOT.war")]) - failure description: {
    "WFLYCTL0412: Required services that are not installed:" => ["jboss.naming.context.java.jboss.datasources.lucasmucida"],
    "WFLYCTL0180: Services with missing/unavailable dependencies" => ["jboss.naming.context.java.module.\"testeJava-1.0-SNAPSHOT\".\"testeJava-1.0-SNAPSHOT\".DefaultDataSource is missing [jboss.naming.context.java.jboss.datasources.lucasmucida]"]
}

不要让我在netbeans上运行它。如果我运行项目，它会创建表，但不会部署和启动项目。

如果我转到localhost：9090并测试连接，两个数据源连接正常。

我在这里缺少什么？

只需将driver.jar放在 module.xml 位置

即可
