Example 1 with HandlerAdapter

use of org.springframework.web.servlet.HandlerAdapter in project spring-integration by spring-projects.

the class IntegrationGraphControllerTests method testIntegrationGraphControllerParser.

@Test
public void testIntegrationGraphControllerParser() throws Exception {
    ConfigurableApplicationContext context = new ClassPathXmlApplicationContext("IntegrationGraphControllerParserTests-context.xml", getClass());
    HandlerMapping handlerMapping = context.getBean(RequestMappingHandlerMapping.class.getName(), HandlerMapping.class);
    HandlerAdapter handlerAdapter = context.getBean(RequestMappingHandlerAdapter.class);
    MockHttpServletRequest request = new MockHttpServletRequest();
    request.setMethod("GET");
    request.setRequestURI("/foo");
    request.addHeader(HttpHeaders.ORIGIN, "http://foo.bar.com");
    MockHttpServletResponse response = new MockHttpServletResponse();
    HandlerExecutionChain executionChain = handlerMapping.getHandler(request);
    assertNotNull(executionChain);
    Object handler = executionChain.getHandler();
    for (HandlerInterceptor handlerInterceptor : executionChain.getInterceptors()) {
        // Assert the CORS config
        assertTrue(handlerInterceptor.preHandle(request, response, handler));
    }
    handlerAdapter.handle(request, response, handler);
    assertEquals(HttpStatus.OK.value(), response.getStatus());
    assertThat(response.getContentAsString(), containsString("\"name\":\"nullChannel\","));
    assertThat(response.getContentAsString(), not(containsString("\"name\":\"myChannel\",")));
    context.getBeanFactory().registerSingleton("myChannel", new DirectChannel());
    request = new MockHttpServletRequest();
    request.setMethod("GET");
    request.setRequestURI("/foo/refresh");
    response = new MockHttpServletResponse();
    executionChain = handlerMapping.getHandler(request);
    assertNotNull(executionChain);
    handler = executionChain.getHandler();
    for (HandlerInterceptor handlerInterceptor : executionChain.getInterceptors()) {
        // Assert the CORS config
        assertTrue(handlerInterceptor.preHandle(request, response, handler));
    }
    handlerAdapter.handle(request, response, handler);
    assertEquals(HttpStatus.OK.value(), response.getStatus());
    assertThat(response.getContentAsString(), containsString("\"name\":\"myChannel\","));
    context.close();
}

Example 2 with HandlerAdapter

use of org.springframework.web.servlet.HandlerAdapter in project openmrs-core by openmrs.

the class WebTestHelper method handle.

public Response handle(final HttpServletRequest request) throws Exception {

        }
    }
    Assert.assertNotNull("The requested URI has no mapping: " + request.getRequestURI(), handlerChain);
    boolean supported = false;

        if (handlerAdapter.supports(handler)) {
            Assert.assertFalse("The requested URI has more than one handler: " + request.getRequestURI(), supported);
