我创建一个新的数据库,'sakila'用pgAdmin III在我的本地PostgreSQL数据库中,然后执行这些SQL语句:
sakila的-schema.sql文件然后sakila的-data.sql
第一个语句执行时没有错误,但是第二个SQL在执行时确实产生了错误:
ERROR: syntax error at or near "1"
LINE 112: 1 PENELOPE GUINESS 2006-02-15 09:34:33
^
********** Error **********
ERROR: syntax error at or near "1"
SQL state: 42601
Character: 2511
如何解决这个错误？
String使用App Engine 存储字段时:
length()是String多少？如何解决此错误:

有人解决了这个问题吗？或者这个插件在Eclipse中根本不受支持？
我只是尝试http-server在Windows 10 Ubuntu Bash上安装NodeJS ,安装工作正常,但运行它以服务静态站点$http-server src会引发此错误:
$ http-server src
/usr/lib/node_modules/http-server/bin/http-server:14
var ifaces = os.networkInterfaces();
^
Error: EINVAL, invalid argument

这里可以缺少什么？在Windows 10上使用Ubuntu bash不支持？
我一直在努力了解如何解决此错误:
SEVERE: Missing dependency for method public java.lang.String com.myrest.FileService.uploadFile(java.io.File,com.sun.jersey.core.header.FormDataContentDisposition) at parameter at index 0 SEVERE: Missing dependency for method public java.lang.String com.myrest.FileService.uploadFile(java.io.File,com.sun.jersey.core.header.FormDataContentDisposition) at parameter at index 1 SEVERE: Method, public java.lang.String com.myrest.FileService.uploadFile(java.io.File,com.sun.jersey.core.header.FormDataContentDisposition), annotated with POST of resource, class com.myrest.FileService, is not recognized as valid resource method.
我正在使用基于Apache Jersey的休息Web服务并执行上传服务.
以前有人遇到过这个错误吗？
我收到此代码的错误:
@POST
@Path("/upload{path:.*}")
@Consumes("multipart/form-data")
@Produces("text/plain")
public String uploadFile(
@FormDataParam("file") File file,
@FormDataParam("file") FormDataContentDisposition fileDetail) {
String fileLocation = "/files/" + fileDetail.getFileName();
System.out.println("Copying file to : " + fileLocation);
return "1";
}
我需要知道是否检查String是否以.xyz之类的内容加上其后的任何字符.
像这样:
myString.endsWidth(".css*")
但是这不会通过我的if语句.一个具体的例子是这种字符串:style.css?v=a1b23
有任何想法吗？
完整示例字符串:
http://xyz.com//static/css/style.css?v=e9b34
为什么 swagger-codegen 生成的项目缺少依赖项？
跑步：
java -jar swagger-codegen-cli.jar generate -l java -i swagger.json
例如生成一个项目：
@javax.annotation.Generated(value = "io.swagger.codegen.languages.JavaClientCodegen", date = "2021-04-27T18:37:06.211+08:00")
public class Table {
@SerializedName("requiredIndexColumns")
private List<Column> requiredIndexColumns = null;
哪里javax.annotation.Generate无法解决。然后编译生成的项目会抛出：Error:(33,18) java: package javax.annotation does not exist
以下是测试方法（使用公开招摇）：
wget https://repo1.maven.org/maven2/io/swagger/swagger-codegen-cli/2.4.19/swagger-codegen-cli-2.4.19.jar -O swagger-codegen-cli.jar
然后运行：
java -jar swagger-codegen-cli.jar generate -l java -i https://petstore.swagger.io/v2/swagger.json -o petstore
我需要在一个内部进行查询Transaction,但是我不知道实体@Id,我所拥有的是一个字段的值,比如用户名而不是ID,
换句话说,我无法创建一个Key查询.如何进行查询以获取实体内部Transaction？
我已经尝试过这篇SO帖子中的说明:
cd ~
git clone git://repo.or.cz/fast-export.git
git init git_repo
cd git_repo
~/fast-export/hg-fast-export.sh -r /path/to/old/mercurial_repo
git checkout HEAD
但是当git checkout HEAD它做的时候抛出:
error: pathspec 'HEAD' did not match any file(s) known to git
这是什么解决方案？
更新:
我设法安装mercurial-python howen当我尝试导入仍然无法工作,错误是:
Error: No --marks option given
做的时候:
C:\fast-export\hg-fast-export.py -r C:\path\to\repo
