原因：java.lang.ClassNotFoundException：javax.servlet.ServletException

Question

当我试图使用Spring-Boot-Test在Spring-Boot1.5.3版本中运行控制器测试时，我发现了以下错误：java.lang.ClassNotFoundException：javax.servlet.ServletException

import static org.hamcrest.CoreMatchers.equalTo;
import static org.hamcrest.CoreMatchers.is;
import static org.junit.Assert.assertThat;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.context.SpringBootTest.WebEnvironment;
import org.springframework.test.context.junit4.SpringRunner;

import com.hanselnpetal.domain.CustomerContact;

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = WebEnvironment.RANDOM_PORT)
@AutoConfigureMockMvc
public class ContactsManagementControllerIntegrationTest {

    @Autowired
    ContactsManagementController contactsManagementController;

    @Test
    public void testAddContactHappyPath() {

        CustomerContact aContact = new CustomerContact();
        aContact.setFirstName("Jenny");
        aContact.setLastName("Johnson");

        // POST our CustomerContact form bean to the controller; check the outcome
        String outcome = contactsManagementController.processAddContactSubmit(aContact);

        // Assert THAT the outcome is as expected
        assertThat(outcome, is(equalTo("success")));
    }


}

我正在运行ContactsManagementControllerIntegrationTest.java类，使用（eclipse）右键单击文件并以junit形式运行。感谢任何帮助。

确保pom.xml（maven）中有以下依赖项

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.0.1</version>
    <scope>provided</scope>
</dependency>
