本文介绍了解决在JSP页面中导入JSONObject时遇到的错误：Onlyatypecanbeimported.*resolvestoapackage的方法。通过将fastjson.jar文件放置到Tomcat的lib目录并重启Tomcat来解决此问题。

解决Only a type can be imported. * resolves to a package

原创

我想在index.jsp中导入JSONObject，代码如下：<%@ page import="com.alibaba.fastjson.JSONObject" %>

运行时报错:

An error occurred at line: [14] in the generated java file: [C:\Users\Administrator\.IntelliJIdea2017.1\system\tomcat\Unnamed_demo\work\Catalina\localhost\service\org\apache\jsp\index_jsp.java]
Only a type can be imported. com.alibaba.fastjson.JSONObject resolves to a package
An error occurred at line: [4] in the jsp file: [/index.jsp]
JSONObject cannot be resolved to a type
1: <%@ page contentType="text/html;charset=UTF-8" language="java" %>
2: <%@ page import="com.alibaba.fastjson.JSONObject" %>
3: <%
4: JSONObject jsonObject = new JSONObject();
5: jsonObject.put("hight",150);
6: jsonObject.put("id",1);
7: jsonObject.put("name","lsw");
An error occurred at line: [4] in the jsp file: [/index.jsp]
JSONObject cannot be resolved to a type

解决方案：将fastjson.jar放到Tomcat中的lib目录下，重启Tomcat即可
