Spring Security——获取当前已登录用户UserDetails对象

源代码 

SecurityContextHolder.getContext().getAuthentication().getPrincipal()

对于WebSecurityConfigurer中关于认证成功的 AuthenticationSuccessHandler 配置DEMO

.successHandler(new AuthenticationSuccessHandler() {
                    @Override
                    public void onAuthenticationSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
                        httpServletResponse.setContentType("application/json;charset=UTF-8");
                        ApiResponse retTemp = ApiResponseUtil.getRetTemp();
                        retTemp.setCode("200");
                        retTemp.setMsg("登录成功");
                        retTemp.setData(authentication.getPrincipal());
                        PrintWriter out = httpServletResponse.getWriter();
                        out.write(new ObjectMapper().writeValueAsString(retTemp));
                        out.flush();
                        out.close();
                    }
                })
