使用Spring Boot 2的401而不是403

spring

随着spring引导 1.5.6.RELEASE我能够发送HTTP状态代码401，而不是403在描述如何让春天的安全响应未经授权（HTTP 401码）如果请求URI不进行认证，这样做：

public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //...
        http.exceptionHandling()
                .authenticationEntryPoint(new Http401AuthenticationEntryPoint("myHeader"));
        //...
    }
}

使用org.springframework.boot.autoconfigure.security.Http401AuthenticationEntryPoint课程。

我刚刚升级到Spring Boot 2.0.0.RELEASE，发现不再有此类（至少在该软件包中）。

问题：

Http401AuthenticationEntryPoint Spring Boot中是否存在此类（）？
如果不是，那么在现有项目中保持相同行为，以便与依赖于此状态代码（401）而不是其他状态的其他实现保持一致的最佳选择是403什么？

默认情况下， Spring Boot 2将401在spring-boot-starter-security添加为依赖项并执行未授权的请求时返回。

如果你放置一些自定义配置来修改安全机制行为，则可能会更改。如果是这种情况，并且你确实需要强制执行该401状态，请阅读以下原始帖子。

Original Post

The classorg.springframework.boot.autoconfigure.security.Http401AuthenticationEntryPoint被取消了org.springframework.security.web.authentication.HttpStatusEntryPoint。

就我而言，代码如下所示：

public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //...
        http.exceptionHandling()
            .authenticationEntryPoint(new HttpStatusEntryPoint(HttpStatus.UNAUTHORIZED));
        //...
    }
}

Bonus

如果你需要在响应正文中返回一些信息或以某种方式自定义响应，则可以执行以下操作：

1-扩展 AuthenticationEntryPoint

public class MyEntryPoint implements AuthenticationEntryPoint {
    private final HttpStatus httpStatus;
    private final Object responseBody;

    public MyEntryPoint(HttpStatus httpStatus, Object responseBody) {
        Assert.notNull(httpStatus, "httpStatus cannot be null");
        Assert.notNull(responseBody, "responseBody cannot be null");
        this.httpStatus = httpStatus;
        this.responseBody = responseBody;
    }

    @Override
    public final void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws IOException {
        response.setStatus(httpStatus.value());

        try (PrintWriter writer = response.getWriter()) {
            writer.print(new ObjectMapper().writeValueAsString(responseBody));
        }
    }
}

2-提供MyEntryPoint安全配置的实例

public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // customize your response body as needed
        Map<String, String> responseBody = new HashMap<>();
        responseBody.put("error", "unauthorized");

        //...
        http.exceptionHandling()
            .authenticationEntryPoint(new MyEntryPoint(HttpStatus.UNAUTHORIZED, responseBody));
        //...
    }
}
