环境 getProperty("SomeValue") 值在 Spring 测试和 Mockito

Question

我正在为控制器类编写 JUnit。我正在使用@PropertySource("classpath:webmvc_test.properties")和Environment反对从属性文件中读取值。在调用getProperty()方法获取null价值。属性文件webmvc_test.properties在类路径下。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();    }    }}

我遇到了同样的问题，当我为它寻找解决方案时，我发现了这篇文章@Autowired + PowerMock：修复一些 Spring Framework 的误用/滥用似乎 powermock 和 spring 之间存在设计问题，无法@Autowire在测试类中正常工作, 所以不要使用@Autowireuse@Mock并期望返回值
