我创建了一个带有 spring 的 REST Web 服务，带有 jdbc 模板的 mysql。我添加了 mysql 连接器 jar。我也在 pom.xml 中包含了 mysql。
在我添加的 tomcat server.xml 中<Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxActive="20" maxIdle="10" maxWait="-1" name="jdbc/test" password="root" type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/test" username="root"/>。
但我仍然无法找到此错误的来源。
添加<ResourceLink name="jdbc/test" global="jdbc/test" type="javax.sql.DataSource" />到 tomcat 的 context.xml 后，我没有收到异常 javax.naming.NameNotFoundException，但我的 ResourceMapping 无法正常工作。
