java - Spring Test无法获取Spring配置Bean

Question

@ContextConfiguration(loader = AnnotationConfigContextLoader.class)
@ActiveProfiles(profiles = "test")
@RunWith(MockitoJUnitRunner.class)
public class ConfigurationTest {
    @Autowired
    private Environment environment;

    @Test
    public void test1() throws Exception {
        environment.getProperty("bhavya",Boolean.class);
    }

    @Configuration
    @Profile("test")
    @ComponentScan(basePackages={"com.bhavya.test"})
    public static class EnvironmentServiceTestConfiguration{

        @Bean
        @Primary
        public Environment environment(){
           return Mockito.mock(Environment.class);
        }
    }
}

我还尝试将 EnvironmentServiceTestConfiguration 作为非内部非静态类，但没有帮助。

这是我在单独的类(class)中尝试的内容:

@RunWith(MockitoJUnitRunner.class)
@Profile("test")
@Configuration
class EnvironmentServiceTestConfiguration{

    @Bean
    @Primary
    public Environment environment(){
        return Mockito.mock(Environment.class)
    }
}

也没用

测试类位于test/java/com.bhavya.test包中。我正在尝试运行这个特定的测试 test1

这是我第一次进行此类测试。我以前从未使用过AnnotationConfigContextLoader.class，请赐教。

堆栈跟踪:

java.lang.NullPointerException

在我有声明的行号:

environment.getProperty("bhavya",Boolean.class);

尝试使用@RunWith(SpringJUnit4ClassRunner.class)

这是一个示例，解释如何做到这一点 https://www.mkyong.com/unittest/junit-spring-integration-example/

以下是适用于问题中示例的代码示例:

包com.example.demo.test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mockito;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.core.env.Environment;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.support.AnnotationConfigContextLoader;

import static org.mockito.Matchers.eq;
import static org.mockito.Mockito.when;

@ContextConfiguration(loader = AnnotationConfigContextLoader.class)
@RunWith(SpringJUnit4ClassRunner.class)
public class ConfigurationTest {
    @Autowired
    private Environment environment;

    @Test
    public void test1() throws Exception {
        System.out.println(environment.getProperty("bhavya",Boolean.class));
    }

    @Configuration
    @ComponentScan(basePackages={"com.example.demo.test"})
    public static class EnvironmentServiceTestConfiguration{

        @Bean
        @Primary
        public Environment environment(){
            Environment env =  Mockito.mock(Environment.class);
            when(env.getProperty(eq("bhavya"), eq(Boolean.class))).thenReturn(true);

            return env;
        }
    }
}
