ssm如何实现用户什么时候登录做了什么的日志管理系统?

可以使用拦截器interceptor 实现

可以使用spring的AOP技术，做切面拦截

切面拦截可以试试

/**
     * 创建用户
     */
    @UserActionAnt(method = "createUser")
    @RequestMapping("createUser")
    @ResponseBody
    public Map<String, Object> createUser(HttpServletRequest request, User user) {
        Map<String, Object> map = businessService.createUser(user);
        return map;
    }

@Aspect
@Component
@Order(value = 1)
public class SysUserLog {

    @Resource
    RecordService recordService;

    @AfterReturning(value = "@annotation(userActionAnt)", returning = "back")
    public void addSysRecord(JoinPoint joinPoint, UserActionAnt userActionAnt, Object back) {
        HttpServletRequest request = (HttpServletRequest) joinPoint.getArgs()[0];
        AdminUser adminUser = (AdminUser) request.getSession().getAttribute("adminUser");
        String name = adminUser.getUserName();
        int id = adminUser.getId();
        String ip = request.getRemoteAddr();
        String method = userActionAnt.method();
        if (method.equals("createUser")) {
            // 创建用户的操作记录
            recordService.createSysRecord(id, name, ip, (Map<String, Object>) back);
        }
