JBoss 错误：org.jboss.as.controller.management-operation]（控制器引导线程）

Question

在配置 mysql 依赖项后尝试运行我的 JBOSS，但出现此错误

09:49:00,138 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([
    ("subsystem" => "datasources"),
    ("data-source" => "TripTicketDS")
]) - failure description: {"WFLYCTL0180: Services with missing/unavailable dependencies" => [
    "jboss.data-source.java:jboss/datasources/TripTicketDS is missing [jboss.jdbc-driver.mysql]",
    "jboss.driver-demander.java:jboss/datasources/TripTicketDS is missing [jboss.jdbc-driver.mysql]"
]}

    "jboss.data-source.java:jboss/datasources/TripTicketDS is missing [jboss.jdbc-driver.mysql]"
]}

我的standalone.xml配置如下

<datasource jndi-name="java:jboss/datasources/TripTicketDS" pool-name="TripTicketDS" enabled="true" use-java-context="true">
    <connection-url>jdbc:mysql://localhost:3306/trip_ticket</connection-url>
    <driver>mysql</driver>
    <security>
        <user-name>root</user-name>
        <password></password>
    </security>
</datasource>

我的 SQL module.xml 文件看起来像这样

<?xml version="1.0" encoding="UTF-8"?> 
<module xmlns="urn:jboss:module:1.3" name="com.sql.mysql"> 
    <resources> 
        <resource-root path="mysql-connector-java-5.1.39-bin.jar"/> 
    </resources> 
    <dependencies> 
        <module name="javax.api"/> 
    </dependencies> 
</module> 

Answer 1

尝试使用 jboss-cli.sh 命令创建模块本身，而不是手动编写 module.xml 文件。这是因为当我们使用一些文本编辑器时，它们可能会将一些隐藏字符附加到我们的文件中。 （特别是当我们在此类编辑器中进行复制和粘贴时）

[standalone@localhost:9990 /]  module add --name=com.mysql.driver  --dependencies=javax.api,javax.transaction.api --resources=/PATH/TO/mysql-connector-java-5.1.35.jar  

[standalone@localhost:9990 /] :reload  
{  
    "outcome" => "success",  
    "result" => undefined  
}  

运行上述命令后，您应该会在以下位置看到生成的 module.xml：“wildfly-version.Final/modules/com/mysql/driver/main/module.xml”

现在创建数据源：

[standalone@localhost:9990 /] /subsystem=datasources/jdbc-driver=mysql/:add(driver-module-name=com.mysql.driver,driver-name=mysql,jdbc-compliant=false,driver-class-name=com.mysql.jdbc.Driver)  
{"outcome" => "success"}  

Answer 2

您的驱动程序名称不正确。它需要与您的模块名称相同，即com.sql.mysql。

我建议不要编辑 XML，而是使用 CLI 或 Web 控制台来添加数据源。使用 CLI，您还可以添加模块。

module add --name=com.mysql --resources=~/Downloads/mysql-connector-java-5.1.37/mysql-connector-java-5.1.37-bin.jar --dependencies=javax.api,javax.transaction.api

/subsystem=datasources/jdbc-driver=com.mysql:add(driver-name=com.mysql, driver-module-name=com.mysql, driver-xa-datasource-class-name=com.mysql.jdbc.jdbc2.optional.MysqlXADataSource)
/subsystem=datasources/data-source=TripTicketDS:add(driver-name=com.mysql, jndi-name="java:jboss/datasources/TripTicketDS", enabled=true, connection-url="jdbc:mysql://localhost:3306/trip_ticket", user-name=root, password="mypassword")
