Spring Boot MockMVC - 请求scoped bean没有正确自动装配

Question

我想要一个请求范围的bean，用过滤器中的数据填充它，然后访问控制器中的数据。当我运行我的应用程序时，这一切都正常，但是当我尝试使用MockMVC进行测试时，我的控制器中的请求范围bean中没有设置数据。

以下是代码：

应用

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan
@EnableAutoConfiguration
public class Application
{
    public static void main(String[] args) {
        ApplicationContext ctx = SpringApplication.run(Application.class, args);
    }
}

RequestScopedBean

import lombok.Data;
import org.springframework.context.annotation.Scope;
import org.springframework.context.annotation.ScopedProxyMode;
import org.springframework.stereotype.Component;  

@Component
@Scope(value = "request", proxyMode = ScopedProxyMode.TARGET_CLASS)
@Data
public class RequestScopedBean {

    private String data;
}

控制器

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class SomeController {

    @Autowired
    private RequestScopedBean requestScopedBean;

    @RequestMapping("/test")
    public ResponseEntity test() {
        return new ResponseEntity(requestScopedBean.getData(), HttpStatus.OK);
    }
}

过滤

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.filter.OncePerRequestFilter;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

@Component
public class SomeFilter extends OncePerRequestFilter {

    @Autowired
    private RequestScopedBean requestScopedBean;

    @Override
    protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException {
        requestScopedBean.setData("Data");

        filterChain.doFilter(httpServletRequest, httpServletResponse);
    }
}

最后测试：

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.SpringApplicationConfiguration;
import org.springframework.mock.web.MockHttpSession;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.is;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@SpringApplicationConfiguration(classes = Application.class)
public class SomeTest {

    @Autowired
    private MockHttpSession session;

    @Autowired
    private WebApplicationContext wac;

    @Autowired
    private SomeFilter someFilter;

    @Test
    public void should_return_data() throws Exception {
        MockMvc mockMvc = MockMvcBuilders.webAppContextSetup(wac)
                .addFilter(someFilter)
                .build();

        MvcResult result = mockMvc.perform(get("/test")
                .session(session))
                .andExpect(status().isOk())
                .andReturn();

        assertThat(result.getResponse().getContentAsString(), is("Data"));
    }
}

如果我将范围更改为＆＃34; session＆＃34;，则测试通过。
