Jersey ExceptionMapper不会映射异常（servlet无法映射mapping）
我的Spring Boot + Jersey REST服务无法正常工作。
EmailExistsException在UserController中引发，但我始终只收到错误500。而且我的异常未记录。
我怀疑异常处理存在一些配置问题，但不知道在哪里进行设置。有什么建议么？
@POST@Path("register")@Produces(MediaType.APPLICATION_JSON)public Response register(NewUserPayload newUserPayload) throws EmailExistsException, MessagingExceptionEmailExistsExceptionMapper
@Providerpublic class EmailExistsExceptionMapper extends AbstractExceptionMapper implements ExceptionMapper<EmailExistsException>{@Overridepublic Response toResponse(EmailExistsException e){ ResponseEntity re = new ResponseEntity(org.springframework.http.HttpStatus.BAD_REQUEST); return this.errorResponse(HttpStatus.BAD_REQUEST_400, re, e);}}AbstractExceptionMapper
@Slf4jpublic abstract class AbstractExceptionMapper{protected Response errorResponse(int status, ResponseEntity responseEntity, Throwable t){ StringWriter sw = new StringWriter(); PrintWriter pw = new PrintWriter(sw); t.printStackTrace(pw); log.error(sw.toString()); // logging stack trace. return customizeResponse(status, responseEntity);}private Response customizeResponse(int status, ResponseEntity responseEntity){ return Response.status(status).entity(responseEntity).build();}}build.gradle
compile("org.springframework.boot:spring-boot-starter-web") { exclude module: ''spring-boot-starter-tomcat''}compile "org.springframework.boot:spring-boot-starter-jetty"compile "org.springframework.boot:spring-boot-starter-security"compile "org.springframework.boot:spring-boot-starter-aop"compile "org.springframework.boot:spring-boot-starter-data-jpa"compile "org.springframework.boot:spring-boot-starter-thymeleaf"compile "org.springframework.boot:spring-boot-starter-jersey"compile ''org.springframework.boot:spring-boot-starter-mail''答案1
小编典典解决了我的问题的答案：
我已经把packages（“ package.name”）; 这是我的根程序包名称，异常映射器的工作原理很吸引人。
@Component@ApplicationPath("/api")public class JerseyConfig extends ResourceConfig{public JerseyConfig(){ packages("package.name"); register(UserController.class); register(TimezoneController.class);}}
Android上Jetty上的Jersey抛出ContainerException：“没有WebApplication提供者”
我创建了一个用Jersey Servlet实例化Jetty服务器的Android.
无论如何,当我启动Jetty并访问REST资源(在我的情况下：http：//192.168.1.12：8080 / api / hello)时,我收到一条带有消息的ContainerException：没有WebApplication提供程序(请参阅下面的异常堆栈跟踪).
知道为什么吗？
我已经将javax包JNDI添加到项目中,因为它是Jetty或Jersey所要求的. Android不喜欢imporitng javax库所以我暂时使用–core-library命令行参数来编译dex文件.
EXCEPTION追踪：

活动代码：
public class StartServerActivity extends Activity {
private Server webServer;
private final static String LOG_TAG = "Jetty";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
System.setProperty("java.net.preferIPv4Stack","true");
System.setProperty("java.net.preferIPv6Addresses","false");
webServer = new Server(8080);
ServletHolder servletHolder = new ServletHolder(ServletContainer.class);
servletHolder.setinitParameter("com.sun.jersey.config.property.packages","com.famenu.server.resources");
servletHolder.setinitParameter("com.sun.jersey.config.property.resourceConfigClass","com.sun.jersey.api.core.PackagesResourceConfig");
ServletContextHandler servletContextHandler = new ServletContextHandler(webServer,"/api");
servletContextHandler.addServlet(servletHolder,"/");
webServer.setHandler(servletContextHandler);
try {
webServer.start();
webServer.join();
Log.d(LOG_TAG,"started Web server");
}
catch (Exception e) {
Log.d(LOG_TAG,"unexpected exception starting Web server: " + e);
}
}
}
我正在使用Jetty 7.3.0.v20110203,Jersey 1.12,Android 1.6
解决方法
因此,要解决此异常,需要将来自jersey-core jersey-server和jersey-servlet的meta-inf / services文件夹添加到apk的meta-inf文件夹中.
然后您将无法使用Eclipse进行部署,但以下命令行将起作用：
cd PROJECT_DIRECTORY
蚂蚁调试
adb install -r“bin / YOUR_PROJECT-debug.apk”
c# – AutoMapper.dll中出现类型“AutoMapper.AutoMapperMappingException”的异常,但未在用户代码中处理
代码
我正在尝试使用以下代码将一些对象映射到viewmodels：
组态：
Mapper.CreateMap<BookcaseItem,FoundBookcaseItemviewmodel>()
.ForMember(x => x.Title,opt => opt.MapFrom(src => src.Book.Title))
.ForMember(x => x.Authors,opt => opt.MapFrom(src => src.Book.Authors.Select(x => x.Name).Aggregate((i,j) => i + "," + j)))
.ForMember(x => x.Identifiers,opt => opt.MapFrom(src => (!string.IsNullOrEmpty(src.Book.Isbn10) ? ("ISBN10: " + src.Book.Isbn10 + "\r\n") : string.Empty) +
(!string.IsNullOrEmpty(src.Book.Isbn13) ? ("ISBN13: " + src.Book.Isbn13) : string.Empty)))
.ForMember(x => x.Pages,opt => opt.MapFrom(src => src.Book.Pages))
.ForMember(x => x.ImageUri,opt => opt.MapFrom(src => src.Book.ThumbnailUriSmall));
用法：
public ActionResult Index()
{
string facebookId = _accountService.GetLoggedInUserFacebookId();
IEnumerable<BookcaseItem> items = _bookcaseItemService.GetBookcaseItemsForUser(facebookId);
IEnumerable<FoundBookcaseItemviewmodel> viewmodels = items.Select(Mapper.Map<BookcaseItem,FoundBookcaseItemviewmodel>);
return PartialView(viewmodels);
}
错误
这会导致以下错误：
An exception of type ‘AutoMapper.AutoMapperMappingException’ occurred in AutoMapper.dll but was not handled in user code
调试数据
首先我确保没有配置错误调用：
Mapper.AssertConfigurationIsValid();
我已经在我的代码中设置了断点,并尝试调试它,但我无法理解它. ‘items’集合中填有数据(由Entity Framework生成的代理类),但’viewmodels’集合中填满了奇怪的数据.它有一个“消息”,说：
Mapping types:
BookcaseItem_B9B52593B2659AC05C47AB2A6E0F7AEA9989CC34D3527DF5B6AA988ED57166FB
-> String System.Data.Entity.DynamicProxies.BookcaseItem_B9B52593B2659AC05C47AB2A6E0F7AEA9989CC34D3527DF5B6AA988ED57166FB
-> System.StringDestination path: FoundBookcaseItemviewmodel.Authors
Source value:
System.Data.Entity.DynamicProxies.BookcaseItem_B9B52593B2659AC05C47AB2A6E0F7AEA9989CC34D3527DF5B6AA988ED57166FB
然后有一个stacktrace属性说：
at System.Linq.Enumerable.WhereSelectEnumerableIterator`2.MoveNext()
at System.Linq.SystemCore_EnumerableDebugView`1.get_Items()
哦,最后还有一个名为“context”的属性,其中包含以下数据：
任何人都可以解释这里发生了什么,为什么我的代码不再工作？我最近对我的解决方案进行了几次更改,但是我已经将它们放回Git,所以不应该对代码有任何影响.
我的设置
> Visual Studio 12 RC
> ASP.NET MVC 4
> .NET Framework 4.0(我有4.5但是引起了太多的错误,所以我用Git回滚到版本4.0)
>实体框架5.0 RC
> AutoMapper 2.1.267
实体和viewmodel
我不知道它是否相关,但这里是映射的源类：
public class BookcaseItem : Entity
{
public Guid Id { get; set; }
public bool IsRenting { get; set; }
public bool IsSwapping { get; set; }
public bool IsSelling { get; set; }
public decimal RentingPrice { get; set; }
public decimal SellingPrice { get; set; }
public string Currency { get; set; }
public bool IsAvailable { get; set; }
public virtual Guid BookId { get; set; }
public virtual Guid UserId { get; set; }
public virtual Book Book { get; set; }
public virtual User User { get; set; }
public BookcaseItem()
{
IsAvailable = true;
Currency = "USD";
}
}
这是映射的目标类：
public class FoundBookcaseItemviewmodel
{
public Guid Id { get; set; }
public bool IsRenting { get; set; }
public bool IsSwapping { get; set; }
public bool IsSelling { get; set; }
public decimal RentingPrice { get; set; }
public decimal SellingPrice { get; set; }
public string Title { get; set; }
public string Authors { get; set; }
public string Identifiers { get; set; }
public int Pages { get; set; }
public string ImageUri { get; set; }
}
解决方法
.ForMember(x => x.Authors," + j)))
c# – AutoMapperMappingException – 缺少类型映射配置或不支持的映射
从挖掘文章和文档,我的猜测是AutoMapper需要对只读类型进行特殊编码.这会是什么样的？
注意：我尝试了Mapper.AssertConfigurationIsValid();正如另一篇文章所建议,但没有任何改进

public Contract GetById(string contractId)
{
var contractDto = _contractRepository.GetById(contractId);
var contract = Mapper.Map<ContractDto,Contract>(contractDto);
Mapper.AssertConfigurationIsValid();
return contract;
}
合同类：
public class Contract
{
public string ContractId { get; set; }
public DateTime ExpirationDate { get; set; }
}
ContractDto类：
public class ContractDto
{
public string ContractId { get; set; }
public DateTime ExpirationDate { get; set; }
}
解决方法
因此,在测试的Setup方法中,您应该像这样调用它：
Mapper.Initialize(cfg => {
cfg.CreateMap<ContractDto,Contract>();
cfg.CreateMap<PartDto,Part>();
});
ElasticSearch PutMapping API：MapperParsingException解析后，根类型映射不为空
我在ES 1.3.4和JDBC For MySql 1.3.4.4的本地实例上拥有River
这条河工作得很好，并在ES中导入数据。我遇到的问题是我的一个字段是文本字段，并且其中包含空格。例如“实时计算器”。ES将其索引为“实时”，“时间”和“计算器”，而不是“实时计算器”。
所以我正在使用下面提到的JSON创建映射：
{
"sale_test": {
"properties": {
"Client": {
"index": "not_analyzed","type": "string"
},"OfferRGU": {
"type": "long"
},"SaleDate": {
"format": "dateOptionalTime","type": "date"
},"State": {
"type": "string"
}
}
}
}
和命令：
curl -XPUT http://localhost:9200/my_index/_mapping/my_type
但是我得到以下提到的错误：
> {"error":"MapperParsingException[Root type mapping not empty after
> parsing! Remaining fields: [sale_test :
> {properties={Client={type=string,index=not_analyzed},> OfferRGU={type=long},SaleDate={type=date,format=dateOptionalTime},> State={type=string}}}]]","status":400}
当我尝试使用下面提到的命令查看当前映射时：
curl -XGET http://localhost:9200/dgses/sale_test_river/_mapping
我只有这个： {}
谢谢你的帮助。
