在Spring Security中，如何配置自定义登录？ spring security添加自定义用户信息

在Spring Security中，你可以使用@PreAuthenticated注解来配置自定义登录。以下是一个示例：

import org.springframework.security.core.Authentication;import org.springframework.security.web.authentication.preauth.PreAuthenticatedAuthenticationToken;import org.springframework.security.web.authentication.www.BasicAuthenticationFilter;import org.springframework.security.web.authentication.www.BasicAuthenticationFilter.ChainMatcher;import org.springframework.security.web.authentication.www.BasicAuthenticationFilter.CredentialsProvider;import org.springframework.security.web.authentication.www.BasicAuthenticationFilter.Customizer;import org.springframework.security.web.authentication.www.BasicAuthenticationFilter.SuccessHandler;public class CustomAuthenticationFilter extends BasicAuthenticationFilter {    private String username;    private String password;    public CustomAuthenticationFilter(String username, String password) {        super("/api/login");        this.username = username;        this.password = password;    }    @Override    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain) throws IOException, ServletException {        String username = getUsernameFromRequest(request);        String password = getPasswordFromRequest(request);        if (username != null && password != null && !username.isEmpty() && !password.isEmpty()) {            Authentication authentication = new PreAuthenticatedAuthenticationToken(username, password);            addSuccessHandler(new SuccessHandler() {                @Override                public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response, Authentication authentication) throws IOException {response.setStatus(HttpStatus.SC_OK);chain.doFilter(request, response);                }            });        } else {            chain.doFilter(request, response);        }    }    private String getUsernameFromRequest(HttpServletRequest request) {        return request.getParameter("username");    }    private String getPasswordFromRequest(HttpServletRequest request) {        return request.getParameter("password");    }}

在这个例子中，我们创建了一个继承自BasicAuthenticationFilter的自定义过滤器，并重写了doFilterInternal方法。在这个方法中，我们从请求参数中获取用户名和密码，然后使用这些信息创建一个新的PreAuthenticatedAuthenticationToken对象，并将其添加到过滤器链中。
