ThreadLocal 緩存存入線程,防止其餘出現線程污染問題

// ThreadLocal裏只存儲了簡單的String對象，也能夠本身定義對象，存儲更加複雜的參數
    private static ThreadLocal<String> threadLocal = new ThreadLocal<String>();

    public static String getPostRequestParams(){
        return threadLocal.get();
    }

    public static void setPostRequestParams(String postRequestParams){
        threadLocal.set(postRequestParams);
    }

    public static void removePostRequestParams(){
        threadLocal.remove();
    }
