[英]Autowire not working in servlet when performing unit test
我有一個標准的HttpServlet。 當我在tomcat上運行autowire時,它可以很好地工作,我已經使用此問題的答案來完成此工作。
但是我無法對其進行單元測試。 它不會自動切絲豆。 我知道這是因為Servlet未使用ServletConfig初始化。 但是我該怎么辦呢?
Servlet類
public class MyServlet extends HttpServlet {
@Autowired
private MyService myService;
public void init(ServletConfig config) {
super.init(config);
SpringBeanAutowiringSupport.processInjectionBasedOnServletContext(this,
config.getServletContext());
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) {
myService.doSomething();// myService is null on unit test
}
}
測試班
@ContextConfiguration(locations = {"classpath:META-INF/spring/test-context.xml"})
@Transactional
@TransactionConfiguration(defaultRollback = true)
@TestExecutionListeners({TransactionalTestExecutionListener.class})
public class MyServletTest extends AbstractTransactionalTestNGSpringContextTests{
private MockHttpServletRequest request;
private MockHttpServletResponse response;
private MyServlet myServlet;
@Test(enabled=true)
public void test() throws Exception {
myServlet = new MyServlet();
myServlet.init();
//myServlet.init(servletConfig); //Where can i get this
request = new MockHttpServletRequest();
response = new MockHttpServletResponse();
//Add stuff to request
.
.
.
myServlet.doPost(request,response);
//request goes through but myService throws a null pointer exception
}
}
將DependencyInjectionTestExecutionListener.class添加到您的TestExecutionListeners中。 並且不要使用“ new MyServlet()”創建它。
