我正在尝试使用此处的信息在 spring-boot服务器中添加静态Web内容

我尝试在上一个链接所说的几个文件夹中添加我需要的.js和.css文件,但它不起作用:

/META-INF/resources/
/resources/

注意:我没有创建/static/和/public/文件夹,因为我不知道项目中的绝对路径.

我也添加了addResourceHandlers方法:

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
if (!registry.hasMappingForPattern("/webjars/**")) {
    registry.addResourceHandler("/webjars/**").addResourceLocations(
            "classpath:/META-INF/resources/webjars/");
}
if (!registry.hasMappingForPattern("/**")) {
    registry.addResourceHandler("/**").addResourceLocations(
            RESOURCE_LOCATIONS);
}
}

HTML文件中的引用如下所示:

<script src="bootstrap-switch.js"></script> 知道如何解决这个问题吗？

更新:

更新2:尝试@jfcorugedo

不起作用.看一下,那是你在说什么？

更新3:尝试@jfcorugedo,第二个建议:

我正在开发一个使用Android Retrofit发送JSON的Android应用程序(它在JSON中转换POJO类).它工作正常,但我需要忽略从POJO类发送JSON一个元素.

有谁知道任何Android Retrofit注释？

例

POJO课程:

public class sendingPojo
{
   long id;
   String text1;
   String text2;//--> I want to ignore that in the JSON

   getId(){return id;}
   setId(long id){
     this.id = id;
   }

   getText1(){return text1;}
   setText1(String text1){
     this.text1 = text1;
   }

   getText2(){return text2;}
   setText2(String text2){
     this.text2 = text2;
   }


}

接口发件人ApiClass

 public interface SvcApi {

 @POST(SENDINGPOJO_SVC_PATH)
 public sendingPojo addsendingPojo(@Body sendingPojo sp);

}

知道如何忽略text2吗？

我正在学习javascript,我想在javascript中初始化一个布尔数组.

我试过这样做:

 var anyBoxesChecked = [];
 var numeroPerguntas = 5;     
 for(int i=0;i<numeroPerguntas;i++)
 {
    anyBoxesChecked.push(false);
 }

但它不起作用.

谷歌搜索后我才发现这种方式:

 public var terroristShooting : boolean[] = BooleanArrayTrue(10);
 function BooleanArrayTrue (size : int) : boolean[] {
     var boolArray = new boolean[size];
     for (var b in boolArray) b = true;
     return boolArray;
 }

}

但我只是初始化一个数组是一个非常困难的方法.任何人都知道另一种方法吗？

我想在我的Repository接口中添加一个方法,该方法可以查找大于long publishdata值的所有数据并按顺序对其进行排序:

我尝试过这个,但它似乎没有起作用:

@Repository
public interface NoticiaRepository extends CrudRepository<Noticia,Long>{

    Noticia findById(long id);
    List<Noticia> findByOrderPublishdateGreaterThanDesc(long publishdate);

}

我使用Spring服务器和JPA来保存变量.

我想保存:

@ElementCollection(fetch=FetchType.EAGER)
    List<List<String>> Listarespostas = new ArrayList<List<String>>();

但显然会出现错误:

我有一个@EntityJPA,有@ElementCollection这样的:

@ElementCollection(fetch=FetchType.EAGER)
List<String> photodescription = new ArrayList<>();

问题是默认情况下,any的列photodescription是a VARCHAR(255).我需要将其增加到10000.

是否存在a中元素的任何anotation,@ElementCollection以设置最大大小,如@Size(max=1000)用于简单的String？

html2canvas我正在尝试使用和从 HTML 创建 PDF jsPDF。首先，我获取所有想要传递给 PDF 的 html 元素image，然后将它们一一添加，如下所示：

   var quality = 1
   var report1 = null
   var report2 = null
   var report3 = null
   var report4 = null
   var report5 = null
   var header = null

   html2canvas(document.querySelector('header'), {scale: quality})
        .then(canvas => {
            header = canvas
            html2canvas(document.querySelector('#report-1'), {scale: quality})
            .then(canvas => {
                report1 = canvas
                html2canvas(document.querySelector('#report-2'), {scale: quality})
                .then(canvas => {
                    report2 = canvas
                    html2canvas(document.querySelector('#report-3'), {scale: quality})
                        .then(canvas => {
                            report3 = canvas
