ClassCastException: com.mysql.jdbc.Driver Wildfly 10.0.0.Final
ClassCastException: com.mysql.jdbc.Driver with Wildfly 10.0.0.Final
我在尝试使用 Wildfly 10 数据源时使用 com.mysql.jdbc.Driver cannot be cast to javax.sql.DataSource。
这是我的独立数据源配置-full.xml:
<datasource jndi-name="java:jboss/datasources/casadocodigoDS" pool-name="casadocodigoDS">
<connection-url>jdbc:mysql://localhost:3306/casadocodigo_javaee</connection-url>
<driver>mysql</driver>
<pool>
<min-pool-size>10</min-pool-size>
<max-pool-size>20</max-pool-size>
</pool>
<security>
<user-name>root</user-name>
</security>
</datasource>
还有我的驱动配置：
<driver name="mysql" module="com.mysql">
<datasource-class>com.mysql.jdbc.Driver</datasource-class>
</driver>
我将 jar 放在文件夹中：modules/system/layers/base/com/mysql/main。使用 module.xml 个文件：
<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="com.mysql">
<resources>
<resource-root path="mysql-connector-java-5.1.35.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
</dependencies>
</module>
有什么想法吗？我正在使用 Wildfly 10.0.0.Final。 当我在 Wildfly 9.0 中进行完全相同的配置时。2.Final 一切正常。
这是完整的 Stacktrace：

谢谢
datasource-class 应该是 java.sql.DataSource 实现。
您应该在驱动程序定义中使用 driver-class 或使用 :
com.mysql.jdbc.jdbc2.optional.MysqlDataSource
com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource
注意，在这种情况下，您必须在数据源定义中使用 connection-properties 而不是 connection-url。
https://issues.jboss.org/browse/WFLY-6198
使用 application.yml 中的 YAML 配置在 spring 引导应用程序中使用以下配置。
spring:
datasource:
driver-class-name: com.mysql.jdbc.Driver
url: jdbc:mysql://127.0.0.1:3306/test
username: root
password: root
它在最新的 spring boot 2.3 版本中运行良好。
我遇到了类似的错误，但针对的是另一个名为 webMethods Designer 的应用程序。我将 DataSource class 更改为 com.mysql.cj.jdbc.MysqlConnectionPoolDataSource 如上所述，它工作正常。感谢分享。
