mysql - 尝试运行 Web 应用程序时出现 fatal error :3:2: The markup in the document following the root element must be well-formed.

Question

我第一次遇到这个错误。我不知道发生了什么，但它似乎与我的 context.xml 文件有关。

这是来自tomcat的错误

[Fatal Error] :3:2: The markup in the document following the root element must be well-formed.

并认为我的 context.xml 文件中只有 3 行

<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/Apo"/>
<Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" maxWait="10000" name="jdbc/apo" password="user" type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/apo" username="myUser"/>

Answer 1

尝试将 Resource 标签放在 Context 标签内，例如:

<Context antiJARLocking="true" path="/Apo">
    <Resource auth="Container" .../>
</Context>
