Question

所以我试图使用Intellij设置glassfish服务器。它曾经工作但突然间它不再起作用了。我得到的错误信息是＆＃34; java.lang.ClassNotFoundException：test.Test＆＃34; （底部的完整堆栈跟踪）。

编辑：不使用maven。

项目结构如下：

Test3.iml是自动生成的，而我自己创建了test.Test.java和web.xml。

Test.java看起来像这样：

package test;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class Test extends HttpServlet{
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        resp.getWriter().write("Bla bla bla");
        resp.getWriter().close();
    }
}

web.xml看起来像这样：

<?xml version='1.0' encoding='UTF-8'?>

<web-app xmlns="http://java.sun.com/xml/ns/javaee" version="2.5">
    <servlet>
        <servlet-name>test</servlet-name>
        <servlet-class>test.Test</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>test</servlet-name>
        <url-pattern>/test</url-pattern>
    </servlet-mapping>
</web-app>

最后，Test3.iml看起来像这样：

<?xml version="1.0" encoding="UTF-8"?>
<module type="JAVA_MODULE" version="4">
  <component name="FacetManager">
    <facet type="web" name="Web">
      <configuration>
        <webroots>
          <root url="file://$MODULE_DIR$/web" relative="/" />
        </webroots>
      </configuration>
    </facet>
  </component>
  <component name="NewModuleRootManager" inherit-compiler-output="true">
    <exclude-output />
    <content url="file://$MODULE_DIR$">
      <sourceFolder url="file://$MODULE_DIR$/src" isTestSource="false" />
    </content>
    <orderEntry type="inheritedJdk" />
    <orderEntry type="sourceFolder" forTests="false" />
    <orderEntry type="library" scope="PROVIDED" name="GlassFish 5.0.0 - RESTful Web Service" level="application_server_libraries" />
    <orderEntry type="library" scope="PROVIDED" name="GlassFish 5.0.0" level="application_server_libraries" />
  </component>
</module>
