我正在為控制器類編寫 JUnit。我正在使用@PropertySource("classpath:webmvc_test.properties")和Environment反對從屬性文件中讀取值。在調用getProperty()方法獲取null價值。屬性文件webmvc_test.properties在類路徑下。TestClass.java:package com.kalavakuri.webmvc.web.controller;import static org.mockito.Mockito.when;import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.view;import java.util.ArrayList;import java.util.List;import org.junit.Before;import org.junit.Test;import org.junit.runner.RunWith;import org.mockito.InjectMocks;import org.mockito.Mock;import org.mockito.MockitoAnnotations;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.annotation.PropertySource;import org.springframework.core.env.Environment;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import org.springframework.test.web.servlet.MockMvc;import org.springframework.test.web.servlet.setup.MockMvcBuilders;import com.kalavakuri.webmvc.business.service.FamilyService;import com.kalavakuri.webmvc.business.valueobject.FamilyAddress;import com.kalavakuri.webmvc.business.valueobject.FamilyVO;import com.kalavakuri.webmvc.init.ApplicationInitializer;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(classes = { ApplicationInitializer.class })@PropertySource("classpath:webmvc_test.properties")public class WelcomeControllerTest { @Mock private FamilyService familyService; @InjectMocks private WelcomeController welcomeController; @Autowired private Environment environment; private MockMvc mockMvc; @Before public void setup() { MockitoAnnotations.initMocks(this); this.mockMvc = MockMvcBuilders.standaloneSetup(welcomeController).build(); } }}

我遇到了同樣的問題，當我為它尋找解決方案時，我發現了這篇文章@Autowired + PowerMock：修復一些 Spring Framework 的誤用/濫用似乎 powermock 和 spring 之間存在設計問題，無法@Autowire在測試類中正常工作, 所以不要使用@Autowireuse@Mock并期望返回值

import com.kalavakuri.webmvc.init.ApplicationInitializer;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = { ApplicationInitializer.class })
@PropertySource("classpath:webmvc_test.properties")
public class WelcomeControllerTest {
@Mock
private FamilyService familyService;
@InjectMocks
private WelcomeController welcomeController;
@Mock
private Environment environment;
private MockMvc mockMvc;
@Before
public void setup() {
MockitoAnnotations.initMocks(this);
this.mockMvc = MockMvcBuilders.standaloneSetup(welcomeController).build();
when(environment.getProperty("familyId")).thenReturn("1");
when(environment.getProperty("familyMemberName")).thenReturn("Ramachandrappa Kalavakuri");
when(environment.getProperty("familyMemberAge")).thenReturn("36");
when(environment.getProperty("familyAddress")).thenReturn("Flat no: 305, 2nd Floor, Prakasa Pride Apartments, Opp To J.P.Morgan, Kadubesinahalli, Bangalore - 560087");
}
@Test
public void welcomePage() throws Exception {
FamilyVO allFamilyMembers = getAllFamilyMembers();
when(familyService.getAllFamilyMembers()).thenReturn(allFamilyMembers);
mockMvc.perform(get("/")).andExpect(status().isOk()).andExpect(view().name("Index"));
}
/**

private FamilyVO getAllFamilyMembers() {
FamilyVO allFamilyMembers = new FamilyVO();
FamilyVO familyVO = new FamilyVO();
familyVO.setFamilyId(Integer.parseInt(environment.getProperty("familyId")));
familyVO.setFamilyMemberName(environment.getProperty("familyMemberName"));
familyVO.setFamilyMemberAge(Integer.parseInt(environment.getProperty("familyMemberAge")));
FamilyAddress familyAddress = new FamilyAddress();
familyAddress.setAddress(environment.getProperty("familyAddress"));
familyVO.setFamilyAddress(familyAddress);
List<FamilyVO> familyVOs = new ArrayList<FamilyVO>();
familyVOs.add(familyVO);
allFamilyMembers.setFamilyVOs(familyVOs);
return allFamilyMembers;
}
}
