**注**：启动项目需要spring-boot-test.jar请使用1.4.4.RELEASE以上包含此版本的springboot启动。低版本的没有上面说的那个jar，项目启动mock对象为null。  
依赖如下

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
            <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                <scope>test</scope>
            </dependency>
            <dependency>
                <groupId>org.mockito</groupId>
                <artifactId>mockito-all</artifactId>
                <version>1.8.5</version>
                <scope>test</scope>
            </dependency>
            <dependency>
                <groupId>commons-logging</groupId>
                <artifactId>commons-logging</artifactId>
                <version>1.1.1</version>
            </dependency>

service 依赖如下

@Service
    public class MessageServiceImpl implements MessageService { 
    
        @Autowired
        ActionService actionService;
    
        @Override
        public String say(String name) {
    
            return actionService.doSay(name);
        }
    
    }

测试代码如下

@RunWith(SpringJUnit4ClassRunner.class)
    @SpringApplicationConfiguration(classes = Application.class)
    @WebAppConfiguration
    public class BeanTest { 
    
        @Autowired
        @InjectMocks//被注入mock对象的类一般是被测试类
        MessageService messageService ;
    
        @Mock//需要mock的bean
        private ActionService actionService;
    
        @Before
        public void setUp() throws Exception {
            Mockito.when(actionService.doSay("name")).thenReturn("name");
        }
    
        @Test
        public void test() {
            // 和上面的before 2选1
            // when(actionService.doSay(anyString())).thenReturn("helloworld");
            System.out.println(messageService.say("name"));
            verify(actionService, times(1));
    
        }
    }
