我怎麼使用REST容易

Question

我有幾下端點「/ REST /角色/」無所謂「

我怎麼趕例如錯誤的請求」趕上不好的URL請求休息/角色/ dbbhwbhb/wdwdwed

如果我使用：

@GET 
    @Path("/{param}") 
    @Produces(MediaType.TEXT_PLAIN) 
    public Response badURLS() { 
     return Response.ok().entity("bad url").build(); 
    } 

這捕獲靜止/角色/ dfsdfsds但其餘/角色/ sdsasd/asdad仍然沒有抓到。我如何設置一個方法，如果沒有我的終端點擊，然後返回默認消息？

JBoss的方法

• https://docs.jboss.org/jbportal/v2.7.0.B1/referenceGuide/html/errorhandling.html

RestEasy的方法

• https://docs.jboss.org/resteasy/docs/2.2.0.GA/userguide/html/ExceptionHandling.html

EDIT

正如我以前發給你的 - 第二個鏈接做的伎倆。

鑑於寫入這樣的方式映射器和結構：

package atata; 

import javax.ws.rs.NotFoundException; 
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 _404Handler implements ExceptionMapper<NotFoundException> { 

    public Response toResponse(NotFoundException exception) { 
     return Response.status(500).entity(new ResponseEntity(333, "Got 404.")).type(MediaType.APPLICATION_JSON).build(); 
    } 

} 

配置

package atata; 

import java.util.HashSet; 
import java.util.Set; 

import javax.ws.rs.core.Application; 


public class EmployeeApplication extends Application { 

    private Set<Object> singletons = new HashSet<Object>(); 

    public EmployeeApplication() { 
     singletons.add(new MessageRestService()); 
     singletons.add(new _404Handler()); 
    } 

    @Override 
    public Set<Object> getSingletons() { 
     return singletons; 
    } 

}

包atata;

import javax.ws.rs.GET; 
import javax.ws.rs.Path; 
import javax.ws.rs.Produces; 
import javax.ws.rs.core.MediaType; 
import javax.ws.rs.core.Response; 

@Path("/roles") 
public class MessageRestService { 

    @GET 
    @Path("/1") 
    @Produces(MediaType.APPLICATION_JSON) 
    public Response badURLS() { 
     return Response.ok().entity("OK").build(); 
    } 

} 

你會得到
