我试图在Wildfly 10.0中添加数据源,但是当我测试连接时,会抛出错误消息:
Anchor['keystone::service::begin']
服务器日志中的错误:
Unexpected HTTP response: 500
Request
{
"address" => [
("subsystem" => "datasources"),
("data-source" => "PostgreCrawlazo")
],
"operation" => "test-connection-in-pool"
}
Response
Internal Server Error

"rolled-back" => true,
"response-headers" => {"process-state" => "reload-required"}
}
我从standalone.xml和module.xml复制相同的配置文件
这是我在standalone.xml中设置数据源的部分原因:
2016-09-01 16:28:40,524 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([

"org.wildfly.data-source.PostgreCrawlazo is missing [jboss.jdbc-driver.postgres]",
"org.wildfly.data-source.PostgreCrawlazo is missing [jboss.jdbc-driver.postgres]"
]
}
和module.xml:
<datasource jndi-name="java:/crawlazo" pool-name="PostgreCrawlazo" enabled="true">
<connection-url>jdbc:postgresql://x.x.x.x:5432/crawlazo</connection-url>
<driver>postgres</driver>

</pool>
<security>

<password>somePasswd</password>
</security>
</datasource>
<drivers>
<driver name="h2" module="com.h2database.h2">
<xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class>
</driver>
<driver name="postgres" module="org.postgres">
<driver-class>org.postgresql.Driver</driver-class>
</driver>
</drivers>
我在部署文件夹中有一个postgresql-9.2-1004.jdbc3.jar。
为什么会出现此错误?我可以忘记配置什么?
答案 0 :(得分:8)
驱动程序jar应该位于模块文件夹中,而不是在部署文件夹中,因为您在写下时暗示了这一点:
<resources>
<resource-root path="postgresql-9.2-1004.jdbc3.jar"/>
</resources>
答案 1 :(得分:6)
我的工作是这样的:
1 - 在WildFly安装目录中创建一个文件夹: \模块\有机\ postgres的\主
2 - 在上面的文件夹中创建一个“module.xml”,内容为:
<?xml version='1.0' encoding='UTF-8'?>
<module xmlns="urn:jboss:module:1.1" name="org.postgres">
<resources>
<resource-root path="postgresql-9.4-1204-jdbc4.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
<module name="javax.servlet.api" optional="true"/>
</dependencies>
</module>
3 - 将驱动程序JAR文件复制到步骤1的同一文件夹
4 - 在standalone.xml中添加数据源:
<datasource jta="false" jndi-name="java:jboss/datasources/YourDS" pool-name="YourDS" enabled="true" use-ccm="false">
<connection-url>jdbc:postgresql://localhost:5432/yourDB</connection-url>
<driver>postgres</driver>
<security>
<user-name>user</user-name>
<password>pass/password>
</security>
<validation>
<validate-on-match>false</validate-on-match>
<background-validation>false</background-validation>
</validation>
<statement>
<share-prepared-statements>false</share-prepared-statements>
</statement>
</datasource>
<drivers>
<driver name="postgres" module="org.postgres">
<driver-class>org.postgresql.Driver</driver-class>
</driver>
</drivers>
答案 2 :(得分:0)
这是我使用jboss-cli创建xa-datasources 的方式 控制台强>:
首先,我在 / opt / wildfly / modules / system / layers / base / org / postgresql / main 上添加了驱动程序。注意我为驱动程序模块创建了文件,但我还添加了jar
[root@localhost main]# ls -lrta
total 776
drwxr-xr-x. 3 root root 18 abr 4 17:10 ..
-rwxr-xr-x. 1 wildfly wildfly 790405 abr 4 17:14 postgresql-42.2.2.jar
-rwxr-xr-x. 1 wildfly wildfly 278 abr 17 17:25 module.xml
drwxr-xr-x. 2 root root 53 abr 17 19:40 .
[root@localhost main]# cat module.xml
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.1" name="org.postgresql" >
<resources>
<resource-root path="postgresql-42.2.2.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.transaction.api"/>
</dependencies>
</module>
接下来,我在控制台上创建了数据源
jboss-cli.sh --connect --controller=192.168.119.116:9990 --commands='xa-data-source add --name=FrontEndDSXA --profile=full --driver-name="postgresql" --enabled="true" --use-ccm="true" --jndi-name="java:jboss/datasources/FrontEndDSXA" --user-name="user" --password="password" --validate-on-match=true --background-validation=false --prepared-statements-cache-size=50 --share-prepared-statements=true --min-pool-size=5 --max-pool-size=150 --pool-prefill=true --transaction-isolation=TRANSACTION_READ_COMMITTED --check-valid-connection-sql="select 1;" --xa-datasource-properties={ "DatabaseName"=>"frontend", "PortNumber"=>"5432", "ServerName"=>"192.168.119.114" }'
接下来,将配置文件完整添加到domain.xml上的my-server-group
<server-groups>
<server-group name="my-server-group" profile="full">
<jvm name="default">
<heap size="64m" max-size="512m"/>
</jvm>
<socket-binding-group ref="full-sockets"/>
</server-group>
</server-groups>
最后,我重新加载了Wildfly(在我的情况下,主机默认为master
)
/opt/wildfly/bin/jboss-cli.sh --connect --controller=192.168.119.116:9990 --commands="reload --host=master"
现在,my-server-group上的所有服务器都可以看到数据源。
希望有所帮助
