我有一个 Restful 应用程序,可以将一些联系人导入数据库。当文件未通过 restful 上传时,我想抛出异常。所以我写了一个异常类 DenemeException,我想发送状态 404,当我运行代码时我得到这个错误 org.jboss.resteasy.spi.UnhandledException: exception.DenemeException: off bu exler 你能帮我吗?
DenemeExceptionMapper.java
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;
@Provider
public class DenemeExceptionMapper implements ExceptionMapper<DenemeException> {
@Override
public Response toResponse(DenemeException ex){
return Response.status(Response.Status.FORBIDDEN).entity(ex.getMessage()).type(MediaType.TEXT_PLAIN).build();
}
}
DenemeException.java
public class DenemeException extends Exception {
/**
*
*/
private static final long serialVersionUID = 1L;
public DenemeException(String message) {
super(message);
}
我的休息 Controller
@POST
@Path("/import")
@Produces({"application/xml","application/json"})
public String saveContacts (@Context HttpServletRequest request, @Context HttpServletResponse response,
@QueryParam("alt") String alt) throws DenemeException {
byte[] content = null;
FileItemStream item = null;
try{
ServletFileUpload upload = new ServletFileUpload();
FileItemIterator iterator = upload.getItemIterator(request);
while (iterator.hasNext()) {
item = iterator.next();
if ("fileUpload".equals(item.getFieldName())){
content = IOUtils.toByteArray(item.openStream());
}
}
}
catch(Exception e){
System.out.println("hata oldu");
throw new DenemeException("off bu exler");
}
最佳答案
您需要使用 Application 注册 ExceptionMapper ,例如
public class HelloWorldApplication extends Application {
private Set<Object> singletons = new HashSet();
private Set<Class<?>> empty = new HashSet();
public HelloWorldApplication() {
// ADD YOUR RESTFUL RESOURCES HERE
this.singletons.add(new SimpleServiceImpl());
this.singletons.add(new AuthenticationServiceImpl());
this.singletons.add(new DenemeExceptionMapper()); //<<< -- HERE IS YOUR EXCEPTION MAPPER !
}
public Set<Class<?>> getClasses() {
return this.empty;
}
public Set<Object> getSingletons() {
return this.singletons;
}
}
