SpringSecurityConfig

.and()
    .logout()
    .logoutUrl("/user/logout")

    .logoutSuccessHandler(new LzcLogoutSuccessHandler()) // 設定退出處理器
.and()

LzcLogoutSuccessHandler

@Slf4j
public class LzcLogoutSuccessHandler implements LogoutSuccessHandler {
    private ObjectMapper objectMapper = new ObjectMapper();
    @Override
    public void onLogoutSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {
        log.info("退出登入");
        // 根據需要返回html頁面或者json


        httpServletResponse.sendRedirect("/login/index");


//        Map<String, Object> map = new HashMap<>();
//        map.put("code", 0);
//        map.put("msg", "退出成功");
//        httpServletResponse.setContentType("application/json;charset=UTF-8");
//        httpServletResponse.getWriter().write(objectMapper.writeValueAsString(map));
    }
