我正在尝试在REST API中创建日志记录实用程序,并且我需要HttpServletRequest提供一些详细信息。
以下是日志记录实用程序的代码:
import javax.servlet.http.HttpServletRequest;
import org.springframework.context.annotation.Scope;
import org.springframework.context.annotation.ScopedProxyMode;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
import lombok.Getter;
import lombok.Setter;
@Component
@Scope(scopeName = "session",proxyMode = ScopedProxyMode.TARGET_CLASS)
@Getter
@Setter
public class LoggingUtil {
private String uri;
private String callerIp;
private String authorization;
public LoggingUtil() {
HttpServletRequest httpServletRequest =
((ServletRequestAttributes)RequestContextHolder.currentRequestAttributes()).getRequest();
this.uri = httpServletRequest.getRequestURI();
this.callerIp = httpServletRequest.getRemoteAddr();
this.authorization = httpServletRequest.getHeader("Authorization");
}
public void log() {
System.out.println("URI is "+this.uri+" Caller IP is "+this.callerIp+"authorization id is "+this.authorization);
}
}
我正在尝试使用JUnit-Mockito框架进行类的单元测试,但是测试范围始终存在InjectMocks无法正常工作的问题。
下面是单元测试用例代码:
import static org.junit.Assert.*;
import static org.mockito.Mockito.mock;
import javax.servlet.http.HttpServletRequest;
import org.junit.BeforeClass;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.omg.CORBA.portable.ResponseHandler;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.web.context.request.RequestContextHolder;
@RunWith(SpringJUnit4ClassRunner.class)
public class LoggingUtilTest {
@InjectMocks
LoggingUtil loggingUtil;
@Mock
static HttpServletRequest httpServletRequest;
@Mock
static MockHttpServletRequest request = new MockHttpServletRequest();
@BeforeClass
public static void setUpBeforeClass() throws Exception {
httpServletRequest = mock(HttpServletRequest.class);
request.setServerName("www.example.com");
request.setRequestURI("/foo");
request.setQueryString("param1=value1¶m");
}
@Test
public final void testLoggingUtil() {
assertEquals(request.getRequestURI(),"/foo");
}
}
以下是控制台中显示的错误:
org.mockito.exceptions.misusing.InjectMocksException:
Cannot instantiate @InjectMocks field named 'loggingUtil' of type 'class in.name.util.LoggingUtil'.
You haven't provided the instance at field declaration so I tried to construct the instance.
However the constructor or the initialization block threw an exception : No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

我想提出以下测试。 希望这会有所帮助:
Optional<List<Integer>>

具有模拟(https://github.com/ivan333m/mock.git)的另一个变体:
@RunWith(SpringJUnit4ClassRunner.class)
public class LoggingUtilTest {
private LoggingUtil loggingUtil;
@Mock
private HttpServletRequest httpServletRequest;
@Before
public void setUpBeforeClass() throws Exception {
RequestContextHolder.setRequestAttributes(new ServletRequestAttributes(httpServletRequest));
}
@Test
public final void testLoggingUtil() {
when(httpServletRequest.getRequestURI()).thenReturn("/foo");
when(httpServletRequest.getRemoteAddr()).thenReturn("10.1.1.11");
when(httpServletRequest.getHeader("Authorization")).thenReturn("xAuth");
loggingUtil = new LoggingUtil();
String requestURI = ReflectionTestUtils.getField(loggingUtil, "uri").toString();
assertEquals(requestURI, "/foo");
String authorization = ReflectionTestUtils.getField(loggingUtil, "authorization").toString();
assertEquals(authorization, "xAuth");
String callerIp = ReflectionTestUtils.getField(loggingUtil, "callerIp").toString();
assertEquals(callerIp, "10.1.1.11");
}
}
