I can verify that it works fine. See below example, where I mock the <code>HttpServletRequest</code> and provide a remote address when <code>getRemoteAddr()</code> is called. I use that mocked value to set a property in the <code>ContainerRequestContext</code>. I then use <code>ArgumentCaptor</code>s to capture the value to test.

<pre><code>import java.io.IOException;

import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerRequestFilter;
import javax.ws.rs.core.Context;

import org.junit.Before;
import org.junit.Test;
import org.mockito.ArgumentCaptor;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.MockitoAnnotations;

import static org.assertj.core.api.Assertions.assertThat;

public class MockitoInjectMocksTest {

 @Mock
 private HttpServletRequest request;

 @Mock
 private ContainerRequestContext requestContext;

 /**
 * With the @InjectMocks annotation, Mockito will
 * inject the filter with the mock HttpServletRequest
 */
 @InjectMocks
 private Filter filter = new Filter();

 @Before
 public void setUp() {
 // Handle all the mock creation and injection.
 MockitoAnnotations.initMocks(this);

 // Mock the HttpServletRequest#getRemoteAddr()
 // method to return a dummy IP address.
 Mockito.when(request.getRemoteAddr())
 .thenReturn("122.21.32.233");
 }

 /**
 * See the `Filter` class below. The `filter()` method doesn't
 * do much. It just grabs the remote IP address from the
 * `HttpServletRequest` and uses it to set a property on
 * the `ContainerRequestContext`. This test asserts that

 * method are the correct arguments. We do that with the
 * help of Mockito's `ArgumentCaptor`,
 */
 @Test
 public void testIpPropertySet() throws Exception {
 // Call the `filter()` method that we are testing,
 // passing in the mock `ContainerRequestContext`.
 // We use a mock so that we can later verify methods
 // on it are called
 filter.filter(requestContext);

 // We create argument captors to capture the args of call to
 // `ContainerRequestContext#setProperty(String, String)`
 ArgumentCaptor&lt;String&gt; propNameArg = ArgumentCaptor.forClass(String.class);
 ArgumentCaptor&lt;String&gt; propValArg = ArgumentCaptor.forClass(String.class);

 // Verify the `ContainerRequestContext#setProperty()`
 // is called. We use the `ArgumentCaptors` to capture
 // the arguments that are passed when `setProperty()`
 // is called.
 Mockito.verify(requestContext)
 .setProperty(propNameArg.capture(), propValArg.capture());

 // Test that the arguments passed in the call to
 // `ContainerRequestContext#setProperty()` are correct.
 assertThat(propNameArg.getValue()).isEqualTo("RemoteAddress");
 assertThat(propValArg.getValue()).isEqualTo("122.21.32.233");
 }

 public static class Filter implements ContainerRequestFilter {

 @Context
 private HttpServletRequest request;

 @Override
 public void filter(ContainerRequestContext requestContext) throws IOException {
 System.out.println(request.getRemoteAddr());
 requestContext.setProperty("RemoteAddress", request.getRemoteAddr());
 }
 }
}
</code></pre>

I can't copy the exact code here but I will put a sample class that explains the problem I am facing.

<pre><code>public XYZ implements ContainerRequestFilter{

 @Context
 HttpServletRequest httpServletRequest;

 @Override
 public void filter(ContainerRequestContext abc){
 //rest of the code below where httpServletRequest is used inside 
 }
}
</code></pre>

So when I write a write test code using <code>@InjectMocks</code>, the <code>HttpServletRequest</code> instance is not injected and is null.

Can anyone help me here what I am misssing. 

I have even used the following in <code>@Before</code> method but still no resolution.

<pre><code>MockitoAnnotations.initMocks(this);
</code></pre>

How to inject HttpServletRequest into ContainerRequestFilter with Mockito @InjectMocks

我不能在这里复制确切的代码，但我会放一个样例类来解释我面临的问题。public XYZ implements ContainerRequestFilter{    @Context    HttpServletRequest httpServletRequest;    @Override    public void...
