为单元测试模拟@AuthenticationPrincipal

Question

我是 spring 和龙目岛的新手。我正在为方法使用@AuthenticationPrincipal 的控制器进行单元测试。根据我的阅读，它将经过身份验证的用户的信息传递到方法中。有没有办法为单元测试模拟这个？

Answer 1

想到的最简单的解决方案是 @WithMockUser。它做你要求的。但是，如果您对它不满意，您可以创建一个注释并根据您的需要进行调整。

我假设您已经尝试过 @WithMockUser，但确实不符合您的需求。

有三项重要任务。第一个是 创建一个注释 然后创建一个 class 代表你系统的用户最后创建 SecurityContextFactory.

让我们从注释开始

import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;

import org.springframework.security.test.context.support.WithSecurityContext;

@Retention(RetentionPolicy.RUNTIME)
@WithSecurityContext(factory = WithMockAaronSecurityContextFactory.class)
public @interface WithAaronUser {
    String username() default "TestUser";
    String[] roles() default { "ROLE_ADMIN" };
}

模拟用户class

import java.util.Collection;
import java.util.stream.Collectors;
import java.util.stream.Stream;

import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;

public class MockUserDetails {

    private String username;
    private Collection<? extends GrantedAuthority> authorities;
    
    public MockUserDetails(String username, String[] roles) {
        this.username = username;
        this.authorities = Stream.of(roles)
                .map(role -> new SimpleGrantedAuthority(role)).collect(Collectors.toSet());
    }

    public String getUsername() {
        return username;
    }

    public Collection<? extends GrantedAuthority> getAuthorities() {
        return authorities;
    }
}

3 最后 SecurityContextFactory。请注意，实现使用 @WithMockUser 使用的相同工厂 class (WithSecurityContextFactory)。

import java.io.Serializable;
import java.util.Collections;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Set;

import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.context.SecurityContext;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.oauth2.provider.OAuth2Authentication;
import org.springframework.security.oauth2.provider.OAuth2Request;
import org.springframework.security.oauth2.provider.authentication.OAuth2AuthenticationDetails;
import org.springframework.security.test.context.support.WithSecurityContextFactory;

public class WithMockAaronSecurityContextFactory implements WithSecurityContextFactory<WithAaronUser> {

    @Override
    public SecurityContext createSecurityContext(WithAaronUser user) {

        MockUserDetails principal = new MockUserDetails(user.username(), user.roles());

        MockHttpServletRequest request = new MockHttpServletRequest();
        request.setServerName("www.example.com");
        request.setRequestURI("/token");
        request.setQueryString("param1=value1&param");
        request.setAttribute(OAuth2AuthenticationDetails.ACCESS_TOKEN_VALUE, "mocked_token");
        OAuth2AuthenticationDetails authDetails = new OAuth2AuthenticationDetails(request);
        
        Map<String, String> decodedDetails = new HashMap<>();
        decodedDetails.put("first_name", "Jean-Claude");
        decodedDetails.put("last_name", "Van Damme");
        authDetails.setDecodedDetails(decodedDetails);
        
        
        UsernamePasswordAuthenticationToken auth = new UsernamePasswordAuthenticationToken(principal.getUsername(), "password", principal.getAuthorities());
        auth.setDetails(authDetails);
        
        
        List<GrantedAuthority> authorities = AuthorityUtils.createAuthorityList("ROLE_ADMIN");
        OAuth2Request oAuth2Request = new OAuth2Request(Collections.emptyMap(), "", authorities, true, Collections.emptySet(), Collections.emptySet(), "http://somethig.com", Collections.emptySet(), Collections.emptyMap());
                    
                    
        OAuth2Authentication oAuth = new OAuth2Authentication(getOauth2Request(), auth);
        oAuth.setDetails(authDetails);
            
        SecurityContext context = SecurityContextHolder.createEmptyContext();
        context.setAuthentication(oAuth);
        return context;
    }
}
