弹簧测试安全性:如何模拟身份验证?

我试图弄清楚如何对我的控制器的 URL 进行单元测试是否正确保护.以防万一有人改变了事情并意外删除了安全设置.

I was trying to figure out how to unit test if my the URLs of my controllers are properly secured. Just in case someone changes things around and accidentally removes security settings.

我的控制器方法如下所示:

My controller method looks like this:

@RequestMapping("/api/v1/resource/test") 
@Secured("ROLE_USER")
public @ResonseBody String test() {
    return "test";
}

我像这样设置了一个 WebTestEnvironment:

I set up a WebTestEnvironment like so:

import javax.annotation.Resource;
import javax.naming.NamingException;
import javax.sql.DataSource;

import org.junit.Before;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.FilterChainProxy;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.ContextConfiguration;
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.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@ContextConfiguration({ 
        "file:src/main/webapp/WEB-INF/spring/security.xml",
        "file:src/main/webapp/WEB-INF/spring/applicationContext.xml",
        "file:src/main/webapp/WEB-INF/spring/servlet-context.xml" })
public class WebappTestEnvironment2 {

    @Resource
    private FilterChainProxy springSecurityFilterChain;

    @Autowired
    @Qualifier("databaseUserService")
    protected UserDetailsService userDetailsService;

    @Autowired
    private WebApplicationContext wac;

    @Autowired
    protected DataSource dataSource;

    protected MockMvc mockMvc;

    protected final Logger logger = LoggerFactory.getLogger(this.getClass());

    protected UsernamePasswordAuthenticationToken getPrincipal(String username) {

        UserDetails user = this.userDetailsService.loadUserByUsername(username);

        UsernamePasswordAuthenticationToken authentication = 
                new UsernamePasswordAuthenticationToken(
                        user, 
                        user.getPassword(), 
                        user.getAuthorities());

        return authentication;
    }

    @Before
    public void setupMockMvc() throws NamingException {

        // setup mock MVC
        this.mockMvc = MockMvcBuilders
                .webAppContextSetup(this.wac)
                .addFilters(this.springSecurityFilterChain)
                .build();
    }
}

在我的实际测试中，我尝试做这样的事情:

In my actual test I tried to do something like this:

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import org.junit.Test;
import org.springframework.mock.web.MockHttpSession;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.web.context.HttpSessionSecurityContextRepository;

import eu.ubicon.webapp.test.WebappTestEnvironment;

public class CopyOfClaimTest extends WebappTestEnvironment {

    @Test
    public void signedIn() throws Exception {

        UsernamePasswordAuthenticationToken principal = 
                this.getPrincipal("test1");

        SecurityContextHolder.getContext().setAuthentication(principal);        

        super.mockMvc
            .perform(
                    get("/api/v1/resource/test")
//                    .principal(principal)
                    .session(session))
            .andExpect(status().isOk());
    }

}

然而，如果仔细观察，这只会在不向 URL 发送实际请求时有所帮助，而仅在功能级别上测试服务时才有帮助.在我的情况下，抛出了拒绝访问"异常:

Yet if one looks closely this only helps when not sending actual requests to URLs, but only when testing services on a function level. In my case an "access denied" exception was thrown:

org.springframework.security.access.AccessDeniedException: Access is denied
    at org.springframework.security.access.vote.AffirmativeBased.decide(AffirmativeBased.java:83) ~[spring-security-core-3.1.3.RELEASE.jar:3.1.3.RELEASE]

        ...

以下两条日志消息值得注意，基本上是说没有用户通过身份验证，表明设置 Principal 不起作用，或者它被覆盖了.

The following two log messages are noteworthy basically saying that no user was authenticated indicating that setting the Principal did not work, or that it was overwritten.
