Question

我正在处理有以下错误的项目。我推荐互联网。跟着他们说的话。但它仍然给出了错误。这浪费了我的一整天。请建议我。

server.xml中：

<GlobalNamingResources>
    <Context docBase="targetapp" path="/targetapp" reloadable="true"/>
    <Resource auth="Container" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" name="UserDatabase" pathname="conf/tomcat-users.xml" type="org.apache.catalina.UserDatabase"/>
   <Resource driverClassName="com.mysql.jdbc.Driver" maxActive="1" maxIdle="30" maxWait="10" name="jdbc/test" password="root" type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/test" username="root"/>
  </GlobalNamingResources>

错误日志：

我添加了这个文件META-INF文件夹然后错误不会再回来。

context.xml中：

<?xml version="1.0" encoding="UTF-8"?>
<Context path="/myapp" docBase="myapp"
   crossContext="true" reloadable="true" debug="1">
          <Resource driverClassName="com.mysql.jdbc.Driver" 
          maxActive="100" maxIdle="30" maxWait="10000" 
          name="jdbc/test" 
          type="javax.sql.DataSource" 
          url="jdbc:mysql://localhost:3306/test" username="root" password="root" />
