小编use*_*109的帖子

我有一个domainPrice设置为BigDecimal数据类型的域类.现在我正在尝试创建一个比较价格的方法,但似乎我不能在BigDecimal数据类型中有比较运算符.我是否必须更改数据类型或是否有其他方法？

我试图在春天将列表转换为页面.我用它转换了它

new PageImpl(users,pageable,users.size());

但现在我有排序和分页本身的问题.当我尝试传递大小和页面时,分页不起作用.

这是我正在使用的代码.

我的控制器

    public ResponseEntity<User> getUsersByProgramId(
        @RequestParam(name = "programId", required = true) Integer programId Pageable pageable) {

    List<User> users = userService.findAllByProgramId(programId);
    Page<User> pages = new PageImpl<User>(users, pageable, users.size());

    return new ResponseEntity<>(pages, HttpStatus.OK);
}

这是我的用户回购

public interface UserRepo extends JpaRepository<User, Integer>{

public List<User> findAllByProgramId(Integer programId);

这是我的服务

    public List<User> findAllByProgramId(Integer programId);

我有一张桌子上有学生的详细信息.这些字段是只读字段,可以在单击编辑按钮时进行编辑.但是我在单击编辑按钮时一次选择该行的所有输入字段时遇到问题.

这是我的HTML代码

<table class="table table-bordered table-striped">
          <thead>
            <tr>
              <th>Checklist</th>
              <th>Id</th>
              <th>Student Name</th>
              <th>Address</th>
              <th>Phone</th>
              <th>Class</th>
              <th colspan="2">Actions</th>
            </tr>
          </thead>
          <tbody>
            <tr>
              <td>
                <input type="checkbox" id="editCheck" class="btn1" />
                <input type="checkbox" id="deleteCheck" />
              </td>
              <td>1</td>
              <td><input type="text" class="form-control item" readonly="readonly" /></td>
              <td><input type="text" class="form-control item" readonly="readonly" /></td>
              <td><input type="text" class="form-control item" readonly="readonly" /></td>
              <td>12</td>
              <td><button type="button" class="btn btn-info btn-xs" id="btn1">Edit</button></td>
              <td><button type="button" class="btn btn-danger btn-xs" id="dbtn1">Delete</button></td>
            </tr>
            <tr>
              <td>
                <input type="checkbox" id="editCheck" class="btn2" />
                <input type="checkbox" …

我在UserController.php中不断收到此错误'Class'App\Http\Controllers\Mail'not found'错误

    public function store(CreateUserRequest $request)
{
    $result = DB::table('clients')->select('client_code','name','email')
                                  ->where('client_code','=',$request->code)
                                  ->where('email','=',$request->email)
                                  ->first();

    if($result){
        $tmp_pass = str_random(10);
        $user = User::create([
            'username'      => $result->name,
            'email'         => $request->email,
            'password'      => $tmp_pass,
            'tmp_pass'      => '',
            'active'        => 0,
            'client_code'   => $request->code
        ]);

        if($user){
            Mail::send('emails.verify',array('username' => $result->name, 'tmp_pass' => $tmp_pass), function($message) use ($user){
                $message->to($user->email, $user->username)
                    ->subject('Verify your Account');
            });
            return Redirect::to('/')
                ->with('message', 'Thanks for signing up! Please check your email.');
        }
        else{
            return Redirect::to('/')
                            ->with('message', 'Something went wrong');
        }
    }
    else{
        Session::flash('message', "Invalid code …

我想DbContext在我的ActionFilter中间件中使用a .可能吗？

public class VerifyProfile : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        using (var context = new SamuraiDbContext())
        {
            var user = filterContext.HttpContext.User.Identity.Name;
            if (context.Profiles.SingleOrDefaultAsync(p => p.IdentityName == user).Result == null)
            {
                filterContext.Result = new RedirectResult("~/admin/setup");
            }
        }
    }
}

但是这段代码using (var context = new SamuraiDbContext())需要传递选项.我应该再次通过DbContextOptionsBuilder()这里还是有其他办法吗？

我想[VerifyProfile]在我的控制器方法中有属性.有可能吗？

我想只从这个字符串中获取链接:

"<p><a href=\"https://www.youtube.com/watch?v=i2yscjyIBsk\">https://www.youtube.com/watch?v=i2yscjyIBsk</a></p>\n"

我希望输出为 https://www.youtube.com/watch?v=i2yscjyIBsk

那么,我怎么能实现它呢？

我试过了:

func matches(for regex: String, in text: String) -> [String] {
do {
let regex = try NSRegularExpression(pattern: regex)
let nsString = text as NSString
????let results = regex.matches(in: text, range: NSRange(location: 0, length: nsString.length))
????return results.map { nsString.substring(with: $0.range)}
} catch let error {????
}

并尝试了这个正则表达式: "<a[^>]+href=\"(.*?)\"[^>]*>.*?</a>"

但我仍然无法弄明白.
