共享全局对象

public class UserContext {

    public static final String SUBJECT_IN_SESSION = "SUBJECT_IN_SESSION";
    public static final String EXPRESSIONS_IN_SESSION = "EXPRESSIONS_IN_SESSION";
    //获取session 公共的整个项目  方便调用  所以写出
    public static HttpSession getSession(){
        ServletRequestAttributes requestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        return requestAttributes.getRequest().getSession();
    }

    //共享当前用户

    //获取当前用户

    }

    //共享当前用户的权限表达式
    public static void setExpressions(List<String> expressions){

在拦截器中拦截请求 获取对应对用户信息  那对应对用户信息set 到对应到对象中 在设置对象到session中   在该项目中调用getsesion 获到对应到详细信息  ‘

String token1 = request.getHeader("token");

String manufactorId = JSONObject.parseObject(jwtUtil.parseJWT(token1).getSubject()).getString("id");

SubJectObjectUtil subJectObjectUtil1 = new SubJectObjectUtil();//设置到实体类中

subJectObjectUtil1.setManufactorId(manufactorId);

UserContext.setCurrentEmp(subJectObjectUtil1); //设置到session 中  

SubJectObjectUtil session1 = UserContext.getCurrentEmp();//获取session中变量

System.out.println(session1.getManufactorId());//获取session中变量
实体类中设置对应需要共享的变量
