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" java.lang.ClassNotFoundException:test.Test" (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>
