I have a pretty simple code.

There is a model with toString overwritten:

policy.ts:

export class Policy {
  public id: number;
  public name: string;
  public description: string;

  toString(): string {
    return this.name + ': ' + this.description;
  }
}

Then I use the Policy model in two ways.

binding to create-policy.component.html:

...
<input type="text" name="name" [(ngModel)]="policy.name" required>

and it in the component create-policy.component.ts:

import { Component, OnInit } from '@angular/core';
import { Policy } from '../models/policy';

@Component({
    selector: …

找不到解决方案似乎是一个简单的问题.例如,我有一个LineBreak"a \na"的字符串.此字符串的System.out.println输出显示2行.但是,我需要以完全相同的形式显示输出,即"a \na".怎么做到这一点？

我收到错误尝试由Gradle构建项目:

  gradle -q acRpm

FAILURE: Build failed with an exception.

* Where:
Script '/Users/anarinsky/eclipse-workspace/aaa/build/gradle-tools/build-scripts/repo-config.gradle' line: 32

* What went wrong:
A problem occurred evaluating script.
> Cannot change strategy of configuration ':fixMe' after it has been resolved.

据我所知,此问题特定于gradle版本> = 3.0.是的,这个脚本适用于2.*版本的gradle.有没有解决方法？我在MacOs Sierra.

尝试将数据从 S3 存储桶中的一个文件夹复制到同一存储桶中的另一文件夹。是否可以通过 GUI 或 AWS CLI 实现？

我在网上看到很多答案,但这对我不起作用.所以,我右键单击该文件并选择"TortoiseGit"/"删除(保持本地)".文件图标变为红色,所有上述目录也变为红色.

如果我再次克隆此目录,我仍然会检查此文件

我试图从上面的目录做"TortoiseGit"/"推送".选项默认为推送.TortoiseGit为用户名和密码创建对话框.但是,这不会改变任何内容 - 仍然不会从存储库中删除静态文件

我有一个curl请求,我想在JMeter中使用它:

curl  -i -X POST -u 'anarinsky@aaa.com:a1234' -d "email=anarinsky@aaa.com" 
-k http://anarinsky.aaa.com/rest/secure/requestOrderMultipleAttr/skuOrderList/AAA_Prod_Go_d2/quantityAdult/1/quantityChild/1/email/anarinsky@aaa.com

这样做的最佳方式是什么？

我正在尝试验证包含电子邮件的 Spring Bean，但是当请求 Bean 中的电子邮件作为空字符串出现时，验证器和 BindingResult 都没有显示任何错误。\n请参阅以下代码：

豆角，扁豆：

import org.springframework.context.annotation.Scope;\nimport org.springframework.stereotype.Component;\nimport org.springmodules.validation.bean.conf.loader.annotation.handler.Email;\nimport org.springmodules.validation.bean.conf.loader.annotation.handler.NotEmpty;\n\n@Component("grouponRedemptionFormBean")\n@Scope("prototype")\npublic class GrouponRedemptionBean {\n\n@NotEmpty(message = "Please enter your email addresss.")\n@Email(message = "Please correct your email.")\nprivate String  email;\n   \xe2\x80\xa6\n}\n

控制器：

import javax.servlet.http.HttpServletRequest;\nimport javax.servlet.http.HttpServletResponse;\nimport javax.validation.Valid;\n\nimport org.apache.log4j.Logger;\nimport org.springframework.beans.factory.annotation.Autowired;\nimport org.springframework.beans.factory.annotation.Qualifier;\nimport org.springframework.stereotype.Controller;\nimport org.springframework.ui.Model;\nimport org.springframework.validation.BeanPropertyBindingResult;\nimport org.springframework.validation.BindingResult;\nimport org.springframework.validation.Errors;\nimport org.springframework.validation.Validator;\nimport org.springframework.web.bind.annotation.ModelAttribute;\nimport org.springframework.web.bind.annotation.RequestMapping;\nimport org.springframework.web.bind.annotation.RequestMethod;\nimport org.springframework.web.bind.annotation.RequestParam;\n\n\n@Controller\npublic class GrouponVoucherRedemptionController {\n\n@Autowired\n@Qualifier("defaultBeanValidator")\nprivate Validator validator;\n\n@RequestMapping(value="/groupon-redemption.ep", method=RequestMethod.POST)\npublic String PostGrouponRedemption(@Valid @ModelAttribute GrouponRedemptionBean grouponRedemptionBean, BindingResult bindingResult,\nHttpServletRequest request, HttpServletResponse response, Model model){\n\n    Errors errors = new BeanPropertyBindingResult(grouponRedemptionBean, "grouponRedemptionFormBean");\n    validator.validate(grouponRedemptionBean, errors);\n    if(errors.hasErrors()) {\n …

这个问题有很多答案，我尝试了我发现的 - 没有用

所以，我试过 sudo mysqld stop。我仍然看到 mysql 进程正在运行：

0   317     1   0 11:15AM ??         0:00.02 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/usr/local/mysql/data --pid-file=/usr/local/mysql/data/anarinsky-mbp.smartdestinations.com.pid


74  3562   317   0 11:40AM ??         0:00.41 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/usr/local/mysql/data/anarinsky-mbp.smartdestinations.com.err --pid-file=/usr/local/mysql/data/anarinsky-mbp.smartdestinations.com.pid

如果我这样做，也会发生同样的情况 “sudo kill -9 3562”.

尝试转到 /Library/LaunchDaemons 不会检索任何 mysql 条目

ls /Library/LaunchDaemons | grep mysql

服务命令不起作用：

-bash: service: command not found

我的 OS X 版本是 10.9.2

我们使用以下代码从 AWS Parameter Store 获取参数：

AWSSimpleSystemsManagement client = AWSSimpleSystemsManagementClientBuilder.standard().build();
    GetParametersByPathRequest request = new GetParametersByPathRequest();
    request.setWithDecryption(true);
    request.setPath(path);
    GetParametersByPathResult result = client.getParametersByPath(request);

设置参数的代码是什么？

我有代码,没有Map,BiFunction和BiConsumer的引用参数化,这个代码导致Java警告.我试图添加此参数化,但这导致编译错误

Map numbers = new HashMap<>();
Map numbers2 = new HashMap();
numbers.put(1, "one");
numbers.put(2, "two");
numbers2.put(3, "three");
numbers2.put(4, "four");
BiFunction func = (k,v) -> v;
BiConsumer cons = (k,v) ->numbers.merge(k,v,func);
numbers2.forEach(cons);
