在 Spring Web 应用程序中，不能将 javax.servlet.ServletException 解析为类型

最佳答案

I guess this may work, in Eclipse select your project → then click on project menu bar on top → goto to properties → click on Targeted Runtimes → now you must select a check box next to the server you are using to run current project → click Apply → then click OK button. That's it, give a try.

It seems to me that eclipse doesn't recognize the java ee web api (servlets, el, and so on). If you're using maven and don't want to configure eclipse with a specified server runtime, put the dependecy below in your web project pom:

<dependency>
<groupId>javax</groupId>
<artifactId>javaee-web-api</artifactId>
<version>7.0</version> <!-- Put here the version of your Java EE app, in my case 7.0 -->
<scope>provided</scope>
</dependency>

import javax.servlet

STEP 1

Go to properties of your project ( with Alt+Enter or righ-click )

STEP 2

check on Apache Tomcat v7.0 under Targeted Runtime and it works.

As almost anyone said, adding a runtime service will solve the problem. But if there is no runtime services or there is something like Google App Engine which is not your favorite any how, click New button right down the Targeted Runtimes list and add a new runtime server environment. Then check it and click OK and let the compiler to compile your project again.

Hope it helps ;)

<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>javax.servlet.jsp-api</artifactId>
<version>2.3.2-b02</version>
<scope>provided</scope>
</dependency>

worked for me.

Add the server(tomcat) from Right click on the Project and select the "Properties" go to "Project Factes" "Runtime tab" other wise "Target Runtime"

if it is maven pom.xml issue, try added this to the pom.xml

 <dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>javax.servlet.jsp-api</artifactId>
<version>2.3.1</version>
<scope>provided</scope>
</dependency>

it will solve the issue.
