小编Dre*_*208的帖子

我想在我的VPS上放一个war文件.但它缺少webapps文件夹.

Tomcat 7在那里,但我正在摸着webapps文件夹的位置.

这是我在服务器上部署war文件的第一次尝试,我只在我的本地完成.

当我找到webapps时,如何将其链接到域？

假设我有一个名为www.foo.com的网站和一个名为software.war的war文件.如何将war文件链接到域？

据我所知,这是正确设置但我收到以下错误:

java.lang.IllegalStateException: Neither BindingResult nor plain target 
object for bean name 'person' available as request attribute

形成

<form action="#" th:action="@{/person}" th:object="${person}" method="post" th:required="required">
    <input type="text" th:field="*{subject}" class="contact col-md-6" placeholder="Name *" th:required="required"/>
    <input type="text" th:field="*{name}" class="contact col-md-6" placeholder="Name *" th:required="required"/>
    <input type="text" th:field="*{lastName}" class="contact col-md-6" placeholder="Name *" th:required="required"/>
    <input type="email" th:field="*{email}" class="contact noMarr col-md-6" placeholder="E-mail address *" th:required="required"/>
    <textarea name="comment" class="contact col-md-12" th:field="*{message}" placeholder="Message *"></textarea>
    <input type="submit" id="submit" class="contact submit" value="Send message"/>
</form>

Person.java

public class Person {

    private int id; …

我与实践@Input和@Output在这里是问题.

在我的家庭组件中,我有以下内容:

<!-- Main Content -->
<div class="container">

    <div *ngIf="registered">
        <login></login>
    </div>

    <div *ngIf="!registered">
        <register></register>
    </div>


</div>

registered 位于 HomeComponent.ts

@Component({
    selector:'home',
    templateUrl:'./home.html',
})

export class HomeComponent {

    registered:Boolean = true;

}

我的目标是registered根据按下的内容更改主组件中的值.

如果在导航栏中按下了注册表单,则表单将更改为注册表单,因为其中的值home component已更改.但是,如果按下登录,它会返回.

我把它变得有点复杂,但这是为了学习目的.

在目录中user我有三个模块Login,Register和UserService.UserService imports the components from登录and注册and exports them. I importUserService intoNavigationBar`模块.

在home.html我想要更改表单的页面中,我只是调用<nav-bar></nav-bar>

@NgModule({

    imports:[
        SmartAdminModule,
        UserModule //has Login and …

我试图像这样呈现一个模态:

HTML

<div class="btn-holder">
            <a (click)="this.open()" class="btn btn-success text-uppercase">Edit My Profile</a>
        </div>

模块:

imports: [BrowserModule, HttpModule,
    RouterModule.forRoot(appRoutes),
      NgbModule.forRoot(),
    EditProfileComponent

  ],

零件:

import {Component} from "@angular/core";

@Component({
    selector: 'edit-profile',
    templateUrl: './editProfile.html'
})
export class EditProfileComponent{

    constructor(){

    }

    submitForm(){

    }

}

问题是我不知道如何让它工作,因为文档含糊不清.建议吗？

我尝试过以下方法:

@Component({
    selector: 'edit-profile',
    templateUrl: './editProfile.html'
})
export class EditProfileComponent{

    closeResult: string;

    constructor(private modalService: NgbModal){ }

    open(content) {
        this.modalService.open(content).result.then((result) => {
            this.closeResult = `Closed with: ${result}`;
        }, (reason) => {
            this.closeResult = `Dismissed ${this.getDismissReason(reason)}`;
        });
    }

    private getDismissReason(reason: any): string …

我有multibuild项目，目前正在设置。每个模块自然都有一个gradle.build仅包含以下内容的文件：

dependencies {

}

在build.gradle我想要的主文件中，每个模块都需要。但是当我做一个gradle build我得到一个错误说：

无法解析外部依赖项org.springframework.boot：spring-boot-starter：，因为未定义存储库。要求：项目：

我正在尝试测试服务，但存储库始终为空。使用 JPA 存储库时，我从未遇到过此问题。我不确定它是否与 ReactiveCrudRepository 有关。有人遇到过这个问题吗？

    @RunWith(MockitoJUnitRunner.class)
    class UserTest {
    

        @InjectMocks
        private UserService underTest;
  
        @Mock
        private  UserRepository userRepository;

        @Mock
        private AutoCloseable closeable;
    
        @BeforeEach
        public void init() {
            closeable = MockitoAnnotations.openMocks(this);
        }
    
        @AfterEach
        public void closeService() throws Exception {
            closeable.close();
        }
    
        @Test
        void getApplicableUsers() {

    
            when(userRepository.findAll().collectList().block()).thenReturn(new ArrayList<>());
            Set<User> expected = underTest.getUsers(getUser(), getUsers());
    
            verify(underTest, times(1)).updateUsers(getUser(),expected);
    
        }

我正在尝试创建 Jupyter Notebook，但我不断收到错误消息

Constraint constraints/compute.vmExternalIpAccess violated for project <projectID>. Add instance <project> to the constraint to use external IP with it.

我创建了 VPC 网络，笔记本尝试创建自身，但我无法克服该错误。

我正在尽力在这里使用很少甚至没有XML.我做了一个非常简单的程序,但它不起作用.希望有人可以帮助我.

public class App {

    public static void main(String[] args) {

        AnnotationConfigApplicationContext ctx = new    
AnnotationConfigApplicationContext(Logger.class);

        Logger logger = ctx.getBean(Logger.class);

        logger.writeConsole("Hello there");
        logger.writeFile("Hi again");

        ctx.close();
    }

}

接口

public interface LogWriter {
    public void write(String text);
}

的FileWriter

public class FileWriter implements LogWriter {

    public void write(String text) {

    System.out.println("FileWriter: " + text);

   }

}

ConsoleWriter

 public class ConsoleWriter implements LogWriter{

      public void write(String text) {
      System.out.println("Console Writer: "+text);

   }

}

我正在学习Angular 2测试,我收到一个目前对我没有意义的错误.

'expect' was used when there was no current spec,

测试:

import {ExperimentsComponent} from "./experiments.component";
import {StateService} from "../common/state.service";
import {ExperimentsService} from "../common/experiments.service";

describe('experiments.component title and body should be correct',() => {

  let stateService = StateService;
  let experimentService = ExperimentsService;

  let app = new ExperimentsComponent(new stateService, new experimentService);

  expect(app.title).toBe('Experiments Page');
  expect(app.body).toBe('This is the about experiments body');

});

组件:

import {Component, OnInit} from "@angular/core";
import {Experiment} from "../common/experiment.model";
import {ExperimentsService} from "../common/experiments.service";
import {StateService} from "../common/state.service";


@Component({
    selector: 'experiments',

我启动了以下两个容器，但卡夫卡说连接被拒绝。

docker run zookeeper和docker run wurstmeister/kafka

我就这样运行它，连接被拒绝。日志中写道：

信息正在打开与服务器 localhost/127.0.0.1:2181 的套接字连接。不会尝试使用 SASL 进行身份验证（未知错误）(org.apache.zookeeper.ClientCnxn)

然后：

警告会话 0x0 服务器为空，意外错误，关闭套接字连接并尝试重新连接（org.apache.zookeeper.ClientCnxn）java.net.ConnectException：连接被拒绝

首先启动了zookeeper，它在2181上启动，当启动kafka时，它会查看2181“zookeeper”，然后对我爆炸。建议？
