我使用jhipster构建一个应用程序,这是一个使用cassandra db的微服务网关,并使用maven构建,在scaffold.i运行gulp命令之后构建正常用于ui的实时重新加载.
我在导航栏和主页上做了一个变化.这也是工作文件,并在家庭和导航栏的json文件中做了一些更改,并在添加搜索框和其他时做了一些小的更改.
它无法重新加载.我停下了gulp&maven并重新启动它们.maven正在构建但是再次没有在localhost中加载该站点
当我跑了一口气时,它向我显示了这个错误.
gulp

我已经为nodejs应用程序编写了两个Javascript文件，这些文件使用express路由和用于创建服务器。作为我的初学者，我对此并不了解。当我运行该应用程序时，它向我显示以下错误：-
/usr/lib/node_modules/express/lib/router/index.js:472
this.stack.push(layer);

index.js文件如下：-
var express = require('express'),
api = require('./api'),
app=express();
app
.use(express.static('./public'))
.use('/api',api)
.get('*',function (req,res) {
res.sendfile('public/index.html');
}).listen(3000);
api.js文件如下：-
var express = require('express'),
bourne = require('bourne'),
bodyParser= require('body-parser'),
db = new bourne('data.json'),
router =express.Router();
router
.use(function(req,res,next){

实际上我生成了买方实体
我正在使用Jhipster构建Web应用程序。
我在Java后端修改了一些东西。现在，当我通过Maven运行它时，它还会同时编译jhipster生成器附带的测试用例，我不想修改它们，而是想跳过它们。
在运行Maven时
./mvnw -DskipTests=true
它并没有跳过那些测试。我曾尝试清理并重新编译，但仍然没有效果。
谁能告诉我如何跳过那些测试。
我正在学习java中的位操作。因此，我将二进制字符串转换为整数字节和短整数。这是我的程序：-
byte sByte,lByte; // 8 bit
short sShort,lShort; // 16 bit
int sInt,lInt; // 32 bit
sByte= (byte)(int)Integer.valueOf("10000000", 2); //Smallest Byte
lByte= (byte) ~sByte;
sShort= (short)(int)Integer.valueOf("1000000000000000", 2); //Smallest Short
lShort = (short) ~sShort;
sInt = (int) (int)Integer.valueOf("10000000000000000000000000000000", 2); //Smallest Int
lInt= (int)~sInt;
System.out.println("\"10000000\" \"8 bit\" byte=>"+sByte+"\t~byte=>"+lByte);
System.out.println("\"1000000000000000\" \"16 bit\" short=>"+sShort+"\t~short=>"+lShort);
System.out.println("\"10000000000000000000000000000000\" \"32 bit\" int=>"+sInt+"\t~int=>"+lInt);
字节和短整型正在转换并给出最小的字节和最小的短整型值，而整数则不进行转换。
它抛出 NumberFormatException 如下：-
Exception in thread "main" java.lang.NumberFormatException: For input string: "10000000000000000000000000000000"

我必须制作一个 jar 来点击 API 来获取人员详细信息列表，该列表基本上有四个字段：id、name、salary、department。
我正在使用 apache httpclient 执行 get 请求，该请求在点击 API 时为我提供了 httpentity。
httpentity提供了一个获取response内容的方法，但它返回的是inputstream。
在通过 inputreader 读取此输入流并将其打印出来时，我确认它为我提供了人员详细信息列表。
但我不知道如何将其转换为人员详细信息列表。
那是 PersonDetails 对象：-
public class PersonDetails {
private UUID id;
private String name;
private String department;
private Integer salary;
public UUID getId() {
return id;
}
public void setId(UUID id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDepartment() {
return department;
}
public void setDepartment(String …我是 flutter 的新手，我构建了一个显示当前纬度和经度的很小的应用程序，这需要我在 pubspec.yaml 中添加两个依赖项：-
location 和 simple_permissions 获取当前用户位置并请求位置权限。
但是当我运行该应用程序时，它显示以下错误：-
